Kangaroos never domesticated can ask humans for help

Kangaroos display gazing and gaze alternations during an unsolvable problem task. Alan G. McElligott, Kristine H. O'Keeffe and Alexandra C. Green. The Royal Society Biology Letters, December 16 2020. https://doi.org/10.1098/rsbl.2020.0607

Abstract: Domestication is generally assumed to have resulted in enhanced communication abilities between non-primate mammals and humans, although the number of species studied is very limited (e.g. cats, Felis catus; dogs, Canis familiaris; wolves, Canis lupus; goats, Capra hircus; horses, Equus caballus). In species without hands for pointing, gazing at humans when dealing with inaccessible food during an unsolvable task, and in particular gaze alternations between a human and the unsolvable task (considered forms of showing), are often interpreted as attempts at referential intentional communication. We report that kangaroos, marsupial mammals that have never been domesticated, actively gazed at an experimenter during an unsolvable problem task (10/11 kangaroos tested), thus challenging the notion that this behaviour results from domestication. Nine of the 10 kangaroos additionally showed gaze alternations between the unsolvable task and experimenter. We propose that the potential occurrence of these behaviours displayed towards humans has been underestimated, owing to a narrow focus on domestic animals, as well as a more general eutherian research bias.

Fellatio among male sanctuary-living chimpanzees during a period of social tension

Fellatio among male sanctuary-living chimpanzees during a period of social tension. Authors: Jake S. Brooker et al. Behaviour, Dec 15 2020. https://doi.org/10.1163/1568539X-bja10053

Abstract: Same-sex sexual behaviour has been documented across the animal kingdom, and is thought to reflect and enhance dyadic cooperation and tolerance. For instance, same-sex fellatio — the reception of a partner’s penis into another’s mouth — has been reported in several mammalian species other than humans. Although same-sex sexual behaviour is observed in our close relatives, the chimpanzees, fellatio appears to be very rare — as yet there are no published reports clearly documenting its occurrence. At Chimfunshi Wildlife Orphanage in Zambia, we observed an instance of fellatio occurring during a post-conflict period between two adult male chimpanzees (born and mother-reared at the sanctuary) where one of the males was the victim. We discuss this event with respect to the putative functions of homosexual behaviour in great apes. Given its rarity in chimpanzees, this fellatio between adult males also highlights the apparent behavioural flexibility present in our close relatives.

4. Discussion

In this report, we described an instance of same-sex fellatio occurring between two sanctuary-living adult male chimpanzees. Although fellatio has been observed in other mammals (Ogawa, 2006; Tan et al., 2009; Sergiel et al., 2014; Sugita, 2016), including captive/semi-captive bonobos (de Waal, 1988; Clay, personal observation) and chimpanzees (Heesen, personal communication) it has not yet been reported among adult chimpanzees during social tension, with two previous reports noting the occurrence of oral-genital contact among play in immature chimpanzees (Savage & Malick, 1977; Savage-Rumbaugh & Wilkerson, 1978). Moreover, while bonobos habitually engage in diverse same-sex sexual behaviour, fellatio appears to be rare and constrained to play contexts involving immatures (de Waal, 1988; Clay, personal observation). To our knowledge, fellatio has not been reported to occur in post-conflict affiliative interactions among either chimpanzees or bonobos. This observation thus provides relevant insights into the potential diversity of its functions in our closest living relatives.

Homosexual interactions, such as those reported here between Max and David, have been hypothesised to reinforce same-sex alliances and increase the propensity to support and cooperate (Kirkpatrick, 2000; Moscovice et al., 2019). Creating such connections may facilitate alliance formation and provide greater opportunities for future cooperation and support during agonism between non-kin. As a low-ranking chimpanzee, it is possible that Max’s request for fellatio in this case may have been driven by a motivation to associate with potential coalition partners, with genital contacts having been shown to facilitate coalitionary support in bonobos, the close relative of chimpanzees (Moscovice et al., 2019). As our closest phylogenetic relatives, studying genital contacts in chimpanzees, including fellatio, in specific contexts may provide clarity on the evolutionary origins of same-sex sexual behaviour within and between the sexes.

Our observation may also reflect fellatio serving a reassurance and alliance testing function by a subordinate male, akin to genital touches and mounting commonly observed between wild male chimpanzees during socially tense periods such as before boundary patrols and intergroup encounters (Wittig et al., 2016; Samuni et al., 2019). It has been proposed that engaging in intimate, risky behaviour such as fellatio can be used to test social relationships and tolerance (Kirkpatrick, 2000).

Chimpanzees are behaviourally innovative and spontaneously develop unique behaviour that may culturally transmit, even if such actions appear to lack adaptive benefits (van Leeuwen et al., 2014). As chimpanzees are not known to habitually engage in same-sex sexual interactions, Max’s repeated attempts to initiate genital contact for reassurance may also represent a behavioural innovation. Observing Max’s group in varying contexts would be necessary to detect whether he possesses a more general tendency for same-sex sexual interactions. Further, longitudinal investigations may show that idiosyncratic sexual behaviour, such as fellatio, is culturally transmitted over time.

Although the functions of fellatio remain to be explored in great apes, its initiation by a lower ranking to a dominant male in a socially tense context makes a novel contribution to the literature. Given the apparent overlaps between this behaviour and genital contacts occurring among the close sister species, the bonobos, systematically comparing sexual behaviours during periods of social tension between Pan would provide greater clarity on how sexual behaviours may be adapted and deployed to fortify and repair social relationships.

The More Who Die, the Less We Care: Evidence from Natural Language Analysis of Online News Articles and Social Media Posts

The More Who Die, the Less We Care: Evidence from Natural Language Analysis of Online News Articles and Social Media Posts. Sudeep Bhatia et al. Risk Analysis, August 25 2020. https://doi.org/10.1111/risa.13582

Abstract: Considerable amount of laboratory and survey‐based research finds that people show disproportional compassionate and affective response to the scope of human mortality risk. According to research on “psychic numbing,” it is often the case that the more who die, the less we care. In the present article, we examine the extent of this phenomenon in verbal behavior, using large corpora of natural language to quantify the affective reactions to loss of life. We analyze valence, arousal, and specific emotional content of over 100,000 mentions of death in news articles and social media posts, and find that language shows an increase in valence (i.e., decreased negative affect) and a decrease in arousal when describing mortality of larger numbers of people. These patterns are most clearly reflected in specific emotions of joy and (in a reverse fashion) of fear and anger. Our results showcase a novel methodology for studying affective decision making, and highlight the robustness and real‐world relevance of psychic numbing. They also offer new insights regarding the psychological underpinnings of psychic numbing, as well as possible interventions for reducing psychic numbing and overcoming social and psychological barriers to action in the face of the world's most serious threats.

Chimpanzees have diverse behavioral repertoires yet lack more complex cultures than humans; invention and social information use in a cumulative task and chimpanzees fail at that

Why do chimpanzees have diverse behavioral repertoires yet lack more complex cultures? Invention and social information use in a cumulative task. Gillian L. Valeai et al. Evolution and Human Behavior, December 16 2020. https://doi.org/10.1016/j.evolhumbehav.2020.11.003

Abstract: Humans are distinctive in their dependence upon products of culture for survival, products that have evolved cumulatively over generations such that many cannot now be created by a single individual. Why the cultural capacity of humans appears unrivalled in the animal kingdom is a topic of ongoing debate. Here we explore whether innovation and/or social learning propensities may constrain the ability of one of our closest living relatives, chimpanzees (Pan troglodytes), to master an extractive foraging and tool-use task designed to afford opportunities for cumulative culture to develop. We further explore the potential demographic characteristics associated with novel task solutions. Chimpanzees (N = 53) were inventive, flexibly exploring the novel task, albeit complex inventions were rare and shaped by prior individual experience with similar tool-use tasks. However, they displayed no evidence of cumulative cultural learning. Communities displayed richer behavioral repertoires and had greater task success than chimpanzees tested in an asocial control condition, but their solution complexity did not surpass what individuals invented. The lack of social transmission of complex and beneficial solutions in contexts like those we studied provides one explanation for the limited cumulative culture observed in this species.

Why Has Burglary Declined by 80 Percent Across Four Decades in the US? Household security, largely absent in the 1970s, improved gradually over time (juveniles finding burglary increasingly difficult)

Farrell, Graham. 2020. “Why Has Burglary Declined by 80 Percent Across Four Decades in the United States? Evidence Relating to the Security Hypothesis.” SocArXiv. January 18. doi:10.31235/osf.io/c78wz

Abstract: Residential burglary imposes significant financial and emotional costs upon victims and society overall. Yet residential burglary in the US has declined by over 80 percent across the last four decades, representing a major social phenomenon that remains largely unexplained. International research indicates a need for investigation of the security hypothesis. Here, 50 years of burglary studies are examined chronologically. A consistent narrative emerges which indicates that household security, largely absent in the 1970s, improved gradually over time. Improvement occurred via three mechanisms: the increased prevalence, quality, and routine use of security fixtures and fittings. In addition, crime displacement declined as fewer household presented easy crime opportunities, and burglars’ average age increased ( juveniles finding burglary increasingly difficult). The likelihood that 50 years of diverse evidence points in the same direction by chance, and without significant contrary evidence, seems remote. Hence the conclusion is that gradual household security improvements played a central role in the decline in residential burglary over time. Implications for theory, policy, and further research are identified.

COVID-19: the emoji density (average number of emojis per tweet) and the relative popularity of specific emojis have changed

How has the coronavirus (COVID-19) pandemic affected global emoji usage? Anwesha Das. Journal of Human Behavior in the Social Environment, Dec 14 2020. https://doi.org/10.1080/10911359.2020.1838383

Abstract: Over the past few decades, emojis have emerged as a popular form of non-linguistic expression in computer-mediated communication. Various factors have been known to affect emoji usage patterns (such as age, gender, platform diversity etc.). The aim of the current study is to explore if the onset of the coronavirus pandemic (2019–20) has affected emoji usage patterns across various countries. The present study was conducted on two sets of tweets, collected before (July, 2019) and during the pandemic (March, 2020). The results suggest that although the usage of specific emojis has not changed noticeably (that is, the popular emojis mostly remained the same), the emoji density (average number of emojis per tweet) and the relative popularity of specific emojis have changed. This could potentially point toward a sense of insufficiency of emojis to express the sentiments associated with the pandemic.

Discussions and conclusions

Emoji usage and their patterns can provide significant insight into human behavior in CMC. In addition, the scope of understanding the different factors affecting emoji usage is vast.

In the present work, emoji usage was compared between two datasets (one collected before and the other after the start of the pandemic), and different characteristic parameters were explored for the purpose of this comparison.

Current results do not show any significant shift in the use of the popular emojis before and after the start of pandemic. It was observed that across all four country-clusters, the most popular emojis more or less remained the same. In addition to this, no emoji that can be associated with the pandemic was present in the top 10 emojis used for each cluster, suggesting that on a general scale, the pandemic does not seem to have altered the most commonly used emojis. Further, the average sentiment score of the emojis used (by country-cluster, for the top 5 emojis) remained approximately the same before and after the start of the pandemic.

However, an interesting point to note here is that across the first three clusters (with the maximum number of COVID-19 patients), the relative popularity of some of the most popular emojis dropped after the start of the pandemic. For example, in cluster 1, the “tears of joy emoji” (the most popular emoji across all clusters), made up 34.36% of all the emojis used, whereas after the start of the pandemic, it made up only 14.69%. A similar pattern is seen in cluster 2 as well, where initially the “tears of joy” emoji makes up 17.72% of all emojis, whereas it makes up only 5.00% after the start of the pandemic. In cluster 3, the values are 7.46 and 4.59 before and after the start of the pandemic, respectively, that is the difference closes in. In cluster 4, this difference almost levels out. A similar pattern is also observed amongst a few of the other top 5 emojis. As mentioned earlier in this paper, the emoji usage density dropped for 75% of the countries (by approximately 40%) in the first three clusters. Hence, indicating that the average usage of emojis by countries which are most affected by the pandemic dropped.

Although this difference is subtle, this could potentially indicate toward a shift in general public sentiment—a possible explanation being that there is a sense of insufficiency in emojis being able to convey the emotions associated with the pandemic. Another explanation could be that people associate emojis to a (comparatively) lighthearted conversation (Danesi, 2016), whereas the pandemic calls for more serious expressions, where emojis may be inadequate.

Nevertheless, it is important to mention here that a number of other factors could possibly affect global emoji usage and emoji usage amongst country-clusters (say clusters having countries with vastly differing economies etc.). The current study aimed to look at only one such possible factor, namely, the onset of the COVID-19 pandemic.

Dishonest behavior is positively correlated with happiness; happiness may provide the cognitive flexibility necessary to reframe and rationalize dishonest acts

Do Happy People Cheat Less? A Field Experiment on Dishonesty. Erez Siniver. Journal of Behavioral and Experimental Economics, December 15 2020, 101658. https://doi.org/10.1016/j.socec.2020.101658

Highlights

• An experiment is designed to examine the effect of happiness on dishonest behavior.

• Dishonest behavior is found to be positively correlated with happiness.

• The positive relationship between dishonesty and happiness is not gender driven.

Abstract: Results of an experimental study designed to examine the effect of happiness on dishonest behavior are reported and analyzed. Passersby on the streets of Tel Aviv were asked to answer the Oxford Happiness Questionnaire (OHQ), which contains 29 multiple-choice questions for measuring Subjective Well-Being (SWB). Each question is answered according to a uniform six-point Likert scale. After filling out the questionnaire, they were invited to perform the Fischbacher and Follmi-Heusi (2013)’s die-under-the-cup (DUTC) task, which incentivizes dishonest behavior. Past research has found a positive relationship between a person's level of honesty and their reported SWB. However, that result is based entirely on a subject's responses to a direct-question survey that simply asks whether he behaves ethically. The present study examines the relationship between dishonest behavior and SWB based on experimental data. Happiness was found to be positively correlated with dishonest behavior, implying that happy people cheat more than unhappy people. A possible explanation for this unexpected result is that happiness may provide the cognitive flexibility necessary to reframe and rationalize dishonest acts. This may pave the way for the commission of dishonest acts by altering how people evaluate the moral implications of their behavior.

Find higher fertility among men with higher cognitive ability among Swedish men using taxation & conscription registers; low income & low cognitive ability independently predict low fertility & high childlessness

Do income and marriage mediate the relationship between cognitive ability and fertility? Data from Swedish taxation and conscriptions registers for men born 1951–1967. Martin Kolk, Kieron Barclay. Intelligence, Volume 84, January–February 2021, 101514. https://doi.org/10.1016/j.intell.2020.101514

Highlights

• We find higher fertility among men with higher cognitive ability among Swedish men using population-level taxation and conscription registers

• Low income and low cognitive ability independently predict low fertility and high childlessness

• Strong evidence of lower access to marriage and reproduction among low status men in contemporary Sweden

Abstract: Recent evidence suggests a positive association between fertility and cognitive ability among Swedish men. In this study we use data on 18 birth cohorts of Swedish men to examine whether and how the relationship between cognitive ability and patterns of childbearing are mediated by income, education and marriage histories. We examine whether the expected positive associations between cognitive ability and life course income can explain this positive association. We also explore the role of marriage for understanding the positive gradient between cognitive ability and fertility. To address these questions we use Swedish population administrative data that holds information on fertility histories, detailed taxation records, and data from conscription registers. We also identify siblings in order to adjust for confounding by shared family background factors. Our results show that while cognitive ability, education, income, marriage, and fertility, are all positively associated with each other, income only explains a part of the observed positive gradient between fertility and cognitive ability. We find that much of the association between cognitive ability and fertility can be explained by marriage, but that a positive association exists among both ever-married and never-married men. Both low income and low cognitive ability are strong predictors of childlessness and low fertility in our population. The results from the full population persist in the sub-sample of brothers.

Keywords: FertilityChildlessnessCognitive abilityIncomeSweden

6. Discussion

In our paper, we show that while income is strongly associated with cognitive ability, men with below average cognitive ability have fewer children, even after adjusting for income. We also find that these differences are magnified for childlessness, and are also very strong for entry into marriage. Consistent with previous research, we find that income and fertility are very strongly associated (Chudnovskaya, 2019; Kolk, 2019), but that the relationship between cognitive ability and fertility persists net of the mediation of income. This is particularly true at lower income levels. Men with low cognitive ability who are above the median in cumulative income between age 18 and 45 have approximately the same number of children as men who score highly on cognitive ability. However, men with low cognitive ability are much less likely to find themselves in the top half of the cumulative income distribution. Among ever-married individuals, the association between cognitive ability and fertility is strongly attenuated, and only really suggests lower fertility among men with the lowest scores on cognitive ability. When comparing full biological brothers with each other, we find a strong positive fertility and cognitive ability gradient even after adjusting for income. Overall, our results indicate that the primary reason that we observe low fertility among men with lower cognitive ability is because of their failure to attract a partner for stable unions for childbearing. In addition to confirming previous findings on cognitive ability and fertility in Sweden (Kolk & Barclay, 2019), the findings of this study provide evidence for the importance of partnership formation for fertility, as well as showing that the intelligence-fertility association persists even after taking cumulative income into account.

Another intriguing empirical pattern that we have observed is that, although men with high cognitive ability have more children overall, men of average cognitive ability had more children than men with high cognitive ability scores among those who never married. These never-married men with high cognitive ability are too few to affect the population-level intelligence-fertility gradient, but may indicate a sub-population that either voluntarily abstains from childbearing and marriage, or in other ways have life trajectories that are associated with high education and income but not traditional patterns of family formation. In our full population analyses, when adjusting for cumulative income, we find that the men with the highest cognitive ability scores have slightly lower fertility and higher childlessness than men with median cognitive ability scores. After adjusting for income we observe slightly lower fertility among high IQ never-married men (left-panels of Fig. 6, Fig. 7), as well as slightly lower fertility among men with high cognitive ability (see Fig. 1). However, our finding that higher cognitive ability men have higher childlessness and lower fertility than men with similar incomes but average cognitive ability is not replicated in sibling comparison models.

In our sibling comparison models we consistently observe lower fertility among men in the bottom half of the cognitive ability distribution. The difference between our population level models and the sibling models is intriguing. Although the results from our population level models are key to understanding how cognitive ability may be distributed in the following generation (though without data on women we cannot speculate about this), the sibling comparison models effectively adjust for all factors shared in the family of origin. It is certainly possible that the results in the full population are confounded by factors that are jointly associated with both cognitive ability as well as fertility outcomes, for example negative experiences in early adulthood such as health shocks or substance abuse.

We believe that our study highlights the importance of examining and interpreting gross associations between cognitive ability and fertility by taking account of the associations between cognitive ability and mediating dimensions of social status and partnership formation. The sociological and demographic literature suggests great variation across the West in the associations between income and fertility, and education and fertility. The findings from our Swedish data may not generalize to other countries. In other high-income countries, the interrelationships between education, income, marriage, and fertility, differ in important ways from Sweden, and our results may to some extent be contingent on the aggregate positive relationships between status and marriage and family formation in Sweden. Nevertheless, we think that the fertility disadvantage of very low cognitive ability men is likely widespread across OECD contexts and that using datasets where such individuals are fully included is important if researchers are to be able to make population-level inferences. Future research on cognitive ability and fertility is therefore advised to pay careful attention to contemporary research in family sociology, demography, and economics on the overall relationship between status and fertility in the focal society. Importantly, the associations between income and fertility and education and fertility typically differ by gender. Unfortunately, we cannot examine any gender differences in the intelligence-fertility gradient in Sweden as we have male-only conscription data.

Our findings also contribute towards the increasing evidence for social polarization of childbearing in many Western countries. We find that the proportion childless and the proportion that never-marry is very substantial among men with lower cognitive ability. We find large separate effects where both low income and low cognitive ability are each strongly associated with a higher probability of childlessness and low completed fertility. When a man has both low income and low cognitive ability, fertility is even lower. This corresponds to the findings from a growing literature that shows that men with low income, low levels of education, worse health, and low cognitive ability, are much less likely to find a childbearing partner in Scandinavia (Barclay & Kolk, 2020; Jalovaara et al., 2019; Jalovaara & Fasang, 2020; Kolk, 2019). Fertility in Scandinavia has traditionally been characterized by relatively small social differences between groups. Our findings of differences by cognitive ability in probabilities of childlessness and ever-marriage of 20 to 30 percentage points clearly show that partnership and childbearing are increasingly less likely for many men with low cognitive ability in contemporary Sweden.

Global trends in the prevalence and incidence of depression: There is a predominant increasing trend in its prevalence over time

Global trends in the prevalence and incidence of depression: a systematic review and meta-analysis. Darío Moreno-Agostino et al. Journal of Affective Disorders, Volume 281, 15 February 2021, Pages 235-243. https://doi.org/10.1016/j.jad.2020.12.035

 

Highlights

• There is a predominant increasing trend in depression prevalence over time

• The increase is not attributable to methodological changes within or across studies

• Studies on depression incidence change with similar designs over time are needed

Abstract

Background: There is mixed evidence regarding the change in the prevalence of depression in the general population over time. This study aimed to synthesise the evidence on studies that use equivalent approaches in equivalent populations across different time points.

Methods: A systematic review was conducted to identify studies focused on the change over time in depression incidence and prevalence in the general population. A random-effects meta-analysis was performed to obtain a pooled effect for the change in the prevalence estimates between the first and last time points considered. Subgroup and meta-regression analyses were used to ascertain differences in the effect sizes by gender, age group, prevalence type, elapsed time between cross-sections, and depression operationalisation.

Results: 19 studies provided information on the change in depression prevalence over time, whereas none provided such information regarding incidence. The pooled odds ratio (OR) and confidence interval (CI) were estimated by using 17 studies: OR=1.35 (95% CI: 1.14, 1.61). Similar pooled effects were obtained for females and males, separately. The high heterogeneity across studies was not explained by any of the design variables considered. No evidence for publication bias was found.

Limitations: The review included published articles up to August 2018, and the information of studies with more than two time points was summarised in a single estimate of change.

Conclusions: There is a predominant increasing trend in the likelihood of experiencing depression over time that seems not to be explainable by study design differences or publication bias alone.

People tend to like interpersonal behaviors that are similar to their own and become bothered by behaviors that are the opposite of their own, consistently across different levels of relationship closeness

An Interpersonal Approach to Social Preference: Examining Patterns and Influences of Liking and Being Bothered by Interpersonal Behaviors of Others. Tianwei V. Du, Katherine M. Thomas and Donald R. Lynam. Journal of Personality Disorders, December 2020. https://guilfordjournals.com/doi/abs/10.1521/pedi_2020_34_496

Abstract: Personality disorders are rooted in maladaptive interpersonal behaviors. Previously, researchers have assessed interpersonal behaviors using self-ratings of one's own behaviors and third-person ratings of dyadic interactions. Few studies have examined individuals’ perceptions of others’ interpersonal behaviors. Using a sample of 470 undergraduate students, the authors examined patterns of interpersonal perception as well as influences of these patterns on psychological functioning. Findings showed that people tend to like interpersonal behaviors that are similar to their own and become bothered by behaviors that are the opposite of their own. Such a pattern is particularly characteristic on the warmth dimension and is consistent across different levels of closeness of the relationship. The authors also found small but significant effects of interpersonal perception on personality and general psychological functioning, above and beyond effects of individuals’ own interpersonal traits. Such findings highlight the importance of including perceptions of others in investigating interpersonal dynamics when understanding personality disorders.

Teams of mostly women performed better than teams of mostly men, when negative relationships existed among team members

When Can Negativity Mean Success? Gender Composition, Negative Relationships and Team Performance. Bret Bradley, Sarah Henry, Benjamin Blake. Small Group Research, December 11, 2020. https://doi.org/10.1177/1046496420959446

Rolf Degen's take: https://twitter.com/DegenRolf/status/1338744287836647424

Abstract: Teams are often plagued by internal discord, such as negative relationships, which can impede successful team performance. While most teams eventually encounter negative relationships, we have limited knowledge on how teams manage this negativity. In this article, we expand scholarship on teams by exploring an inherent team characteristic, gender composition, to assess its role in how teams cope with negative relationships. On the one hand, social role theory suggests that teams comprised of more women will perform better in the presence of negative relationships. On the other hand, theories and evidence on personality and individual differences suggest that teams comprised of more men will perform better in the presence of negative relationships. We studied 151 student project teams, and found that teams of mostly women performed better than teams of mostly men, when negative relationships existed among team members. We discuss the implications of these findings for research and practice.

Social information is immensely valuable, but lots of it is wasted (we fail to give such information its optimal weight); egocentric discounting is a pervasive effect, but we have single unifying explanation for it

Morin, Olivier, Pierre O. Jacquet, Krist Vaesen, and Alberto Acerbi. 2020. “Social Information Use and Social Information Waste.” SocArXiv. December 10. doi:10.1098/rstb.2020.0052

Abstract: Social information is immensely valuable. Yet we waste it. The information we get from observing other humans and from communicating with them is a cheap and reliable informational resource. It is considered the backbone of human cultural evolution. Theories and models focused on the evolution of social learning show the great adaptive benefits of evolving cognitive tools to process it. In spite of this, human adults in the experimental literature use social information quite inefficiently: they do not take it sufficiently into account. A comprehensive review of the literature on five experimental tasks documented 45 studies showing social information waste, and 4 studies showing social information being over-used. These studies cover “egocentric discounting” phenomena as studied by social psychology, but also include experimental social learning studies. Social information waste means that human adults fail to give social information its optimal weight. Both proximal explanations and accounts derived from evolutionary theory leave crucial aspects of the phenomenon unaccounted for: egocentric discounting is a pervasive effect that no single unifying explanation fully captures. Cultural evolutionary theory’s insistence on the power and benefits of social influence is to be balanced against this phenomenon.

The Role of Subjective and Objective Social Status in the Generation of Envy: Those who were the most respected in the eyes of others were envied more than the richest ones

The Role of Subjective and Objective Social Status in the Generation of Envy. Henrietta Bolló, Dzsenifer Roxána Háger, Manuel Galvan and Gábor Orosz. Front. Psychol., December 15 2020. https://doi.org/10.3389/fpsyg.2020.513495

Abstract: Envy is a negative emotion experienced in response to another person’s higher status. However, little is known about the composition of its most important element: status. The present research investigates the two main forms of social status (objective and subjective) in the generation of envy. In Study 1, participants recounted real-life situations when they felt envious; in Study 2 we examined whether the effect was the same in a controlled situation. We consistently found that those who were the most respected in the eyes of others were envied more than the richest ones. Furthermore, perceived deservingness of the superior other’s success differentiated between benign and malicious envy. Although previous studies focused on material comparisons when investigating envy, our results indicate that envy is rather a subjective social status related emotion. Not material, but social advantage of the superior other causes the most painful envy and future studies should put more emphasis on this type of social comparison in envy research.

General Discussion

According to the social-functional approach to envy, the goal of envy is to lessen the social status gap between the self and a superior other (Van de Ven et al., 2009; Lange and Crusius, 2015a,b). Previous research on envy was more focused on material inequalities (Carter and Gilovich, 2010; Fiske, 2011; Lin and Utz, 2015; Lin et al., 2018); the present research aimed to investigate the subjective facet of social status as well, taking into account the role of deservingness. Our findings suggest that SSS intensifies feelings of envy more than OSS and that deservingness helps differentiate between benign and malicious envy. A potential explanation for the prominent role of SSS in envy is that social factors are more related to our identity and cause more frustration, which can result in envy (Salovey and Rodin, 1984; DeSteno and Salovey, 1996; Lin et al., 2018). It has to be noted that previous studies (Salovey and Rodin, 1984; DeSteno and Salovey, 1996) confirmed this relationship in the case of jealousy, although recent research gave empirical evidence for the role of self-relevance in the case of envy as well (Lin et al., 2018). Although envy and jealousy have some overlap regarding hostility, lowered self-esteem, and sadness, they are two distinct emotions (Parrott and Smith, 1993). Envy is more focused on inferiority and therefore can be characterized by self-diminishment and resentment, while jealousy is more focused on the threat of loss of another’s fidelity and can be characterized by anxiety, distrust, and anger (Parrott and Smith, 1993).

There are two contradicting theories regarding the role of material things in envy. Some scholars suggest that, as material possessions are easily comparable, individuals compare themselves more frequently in this domain, and that consequently envy is experienced more in relation to material possessions (Carter and Gilovich, 2010). In contrast, others suggest that envy is most intense when social comparison is important for a person’s identity (Salovey and Rodin, 1984; Bolló et al., 2018).

Furthermore, although previous studies indicated that individuals tend to exaggerate the importance of OSS in hypothetical situations (Bolló et al., 2018), this study did not confirm this finding. In Study 2 respondents were asked to evaluate their feelings in a hypothetical situation, but SSS still played a more prominent role. However, in Study 2 respondents were asked to imagine that they were in the role of the envier, while in previous studies they were either the envied one (Lin et al., 2018) or the comparison affected their own status (Bolló et al., 2018). The findings of this study therefore suggest that there is a discrepancy between what individuals believe others are envious of and what they themselves are envious of, which can be a direction for future research.

Furthermore, the present research study replicated previous findings about the role of deservingness in envy (Parrott and Smith, 1993; Lange and Crusius, 2015b; Crusius and Lange, 2017; Crusius et al., 2017). Benign envy was more likely to be expressed when the superior other’s outcome was deserved and malicious envy was more likely when it was seen to be (Study 1) or characterized as (Study 2) undeserved. In the present research we applied the value theory of deservingness by Feather (1992). By definition, deservingness refers to whether the outcome is contingent with the situation: if there is a fit between the situation and the outcome it is deserved, otherwise it is undeserved (Feather, 1999). Based on Feather (1992), in Study 2 we characterized deserved advantage by positively valued behaviors (hard work in the case of OSS and being dependable in the case of SSS) and undeserved advantage by a negatively valued behavior (“cozying up” to others) and both were followed by the same positive outcome. In the present study, attributing the superior other’s success as undeserved (negatively valued behavior followed by a positive outcome) promoted malicious envy, while attributing the other’s advantage as deserved (positively valued behavior followed by a positive outcome) promoted benign envy. According to attribution theory (Hareli and Weiner, 2002), balanced structures (Heider, 1958) carry the possibility of controllability (namely that hard work pays off) and individuals will have the motivation to work hard and become as successful as the superior other.

In summary, the findings indicate that SSS and OSS play different roles in the generation of envy. SSS is more relevant in upward social comparisons leading to benign and malicious envy, and material possessions do not motivate people to move up the social hierarchy to the same extent.

Limitations and Future Studies

Although this study has important implications in relation to envy, there are a number of limitations which should be taken into account. Firstly, females were over-represented in the sample, which may lead to biased results. Previous studies suggest that women are more likely to avoid socially comparative situations that men (Niederle and Vesterlund, 2007; Rand, 2017), which can have an effect on envy.

Secondly, both studies were cross-sectional and no behavioral measures were used. Future studies should apply longitudinal or experimental design with behavioral measures.

Thirdly, Study 2 was a situation evaluation task with an imaginary scenario, so participants’ reactions in this imaginary situation may differ from their reactions in a real-life scenario. Although applying a vignette method in Study 2 can lead to interesting and informative contributions, there are limitations, especially for examining potentially less desirable emotions like envy (Van Dijk et al., 2006). For example, in the undeserved conditions of Study 2 participants might draw negative evaluations of not only the outcome but also the person themselves and it might also affect their answer about envy, added to “deservedness,” as Crusius and Lange (2014) pointed out previously that malicious envy biases attention toward the envied person rather than the advantage of this person. In future studies, this bias can be treated with manipulating not only the deservingness of the outcome but also the characteristics of the person, and then investigating their interactions.

However, vignette studies have long been used in experimental emotion research, offering the possibility to systematically control for other factors by providing identical information to respondents, thereby increasing their internal validity (Powell et al., 2008). In addition, there is empirical evidence that vignette studies can be highly generalizable to real life behavior, while overcoming the ethical, practical, and scientific limitations associated with alternative methods (Evans et al., 2015). Furthermore, respondents were assured about their anonymity and were encouraged to answer honestly. In sum, despite the limitations of online hypothetical methods, they are widely used in envy research (for example, Parrott and Smith, 1993; Lange and Crusius, 2015b; Poelker et al., 2019) and there is also empirical evidence that people do not seem more reluctant to report envy than other negative social emotions (Hareli and Weiner, 2002).

There are several potential directions for future studies, but the most important is that more emphasis should be placed on social factors instead of material inequalities in envy research. SSS is a broad conception but investigating its elements, such as respect or influence, could be a fruitful area. Furthermore, future studies should investigate possible mediating variables between envy and social status. Some possible mediators may be status maintenance strategies, prestige, and dominance. Previous research indicates that prestige is related to SSS (Bolló et al., 2018) and benign envy (Crusius and Lange, 2017).

Losing Elections' Effects on Political and Social Attitudes and Subjective Well-being: Most effects are bigger for those with strong partisan attachments, some are bigger for men

Toshkov, Dimiter, and Honorata Mazepus. 2020. “Winning and Losing Democratic Elections: Effects on Political and Social Attitudes and Subjective Well-being.” OSF Preprints. December 14. doi:10.31219/osf.io/j9dty

Abstract: In democracies, losing free and fair elections is a normal part of politics, and the consent of losers is needed for the survival of democratic government itself. But being on the losing side of the electoral contest can trigger important changes in the political and social attitudes, and even in the life outlook and subjective well-being of citizens. Based on individual-level survey data from 25 European countries and two time periods (2012 and 2018), we show that there is a significant gap between people who have voted for the parties in government and the losers of democratic elections when it comes to a wide set of political attitudes, including political trust, perceived efficacy and importance of government responsiveness and perceptions about how politics and government work. We also find that the gap between winners and losers extends to social trust, country attachment, feeling happy, healthy, safe, and optimistic, life satisfaction and perceived place in society. Most of these effects are greater in new democracies and for citizens with strong partisan attachments, some are bigger for men, and many are mediated by satisfaction with the government. Losing elections is hard for politics, but it could also be hard for the soul.

For people with an unrestricted sociosexual orientation (i.e., interested in a short-term, sexual relationship), however, self-control was related to lower selectivity...

The role of self-control and sociosexual orientation in partner selection: A speed-dating study. Tila M. Pronk et al. Journal of Social and Personal Relationships, December 9, 2020. https://doi.org/10.1177/0265407520977675

Abstract: Self-control is a crucial factor in maintaining an established romantic relationship, but its role in relationship formation is understudied. The current study tested whether trait self-control is related to a more selective approach toward romantic partners. Over 4 years, we organized 11 speed-date events at which a total of 342 single, heterosexual participants met potential partners. Our results indicated that there was no main effect of self-control on selectivity. However, there was an interaction between self-control and sociosexual orientation (SOI) in predicting selectivity. Specifically, self-control was positively related to selectivity for people with a restricted SOI (i.e., interested in a long-term, stable relationship). For people with an unrestricted SOI (i.e., interested in a short-term, sexual relationship), however, self-control was related to lower selectivity. Our findings point to the flexibility of self-control in facilitating goal progress, stimulating people to refrain from—or act on—their impulses, depending on their own personal mating goals.

I thought this was already debunked, but these authors say that higher-class individuals made more errors than lower-class individuals in the Director Task (requires participants to assume the visual perspective of another person)

Social Class Predicts Emotion Perception and Perspective-Taking Performance in Adults. Pia Dietze, Eric D. Knowles. Personality and Social Psychology Bulletin, April 27, 2020. https://doi.org/10.1177/0146167220914116

Abstract: “Theory of Mind” (ToM; people’s ability to infer and use information about others’ mental states) varies across cultures. In four studies (N = 881), including two preregistered replications, we show that social class predicts performance on ToM tasks. In Studies 1A and 1B, we provide new evidence for a relationship between social class and emotion perception: Higher-class individuals performed more poorly than their lower-class counterparts on the Reading the Mind in the Eyes Test, which has participants infer the emotional states of targets from images of their eyes. In Studies 2A and 2B, we provide the first evidence that social class predicts visual perspective taking: Higher-class individuals made more errors than lower-class individuals in the Director Task, which requires participants to assume the visual perspective of another person. Potential mechanisms linking social class to performance in different ToM domains, as well as implications for deficiency-centered perspectives on low social class, are discussed.

Is Touch in Romantic Relationships Universally Beneficial for Psychological Well-Being? The Role of Attachment Avoidance

Is Touch in Romantic Relationships Universally Beneficial for Psychological Well-Being? The Role of Attachment Avoidance. Anik Debrot et al. Personality and Social Psychology Bulletin, December 7, 2020. https://doi.org/10.1177/0146167220977709

Abstract: Affectionate touch is crucial for well-being. However, attachment avoidance is associated with negative attitudes toward touch. We tested two preregistered hypotheses about how attachment avoidance influences the association between touch in romantic couples and psychological well-being. We examined whether greater attachment avoidance is associated with a reduced link between touch and well-being, and/or whether reduced touch mediates the relationship between attachment avoidance and lower well-being. Across three studies, including two dyadic ones, we measured retrospective self-reports (Studies 1 and 2), laboratory observations (Study 2), and daily experiences (Study 3) of touch. Touch and well-being were positively associated, and attachment avoidance was associated with lower well-being and less frequent touch. Touch was associated with greater well-being regardless of level of attachment avoidance, and less frequent touch mediated the negative association between attachment avoidance and well-being in most analyses. This underscores the importance of touch, even for those valuing distance and autonomy.

No Detectable Electroencephalographic Activity 24-hours After Clinical Declaration of Death among Tibetan Buddhist Meditators in apparent tukdam, a putative postmortem meditation state

No Detectable Electroencephalographic Activity 24-hours After Clinical Declaration of Death among Tibetan Buddhist Meditators in apparent tukdam, a putative postmortem meditation state. Dylan T. Lott1 et al. Front. Psychol., Dec 2020. doi: 10.3389/fpsyg.2020.599190

Abstract: Recent EEG studies on the early postmortem interval that suggest the persistence of electrophysiological coherence and connectivity in the brain of animals and humans reinforce the need for further investigation of the relationship between the brain’s activity and the dying process. Neuroscience is now in a position to empirically evaluate the extended process of dying and more specifically, to investigate the possibility of brain activity following the cessation of cardiac and respiratory function. Under the direction of the Center for Healthy Minds at the University of Wisconsin-Madison, research was conducted in India on a postmortem meditative state cultivated by some Tibetan Buddhist practitioners in which decomposition is putatively delayed. For all healthy baseline (HB) and post-mortem (PM) subjects presented here, we collected resting state electroencephalographic data, Mismatch Negativity (MMN), and Auditory Brainstem Response (ABR). In this study, we demonstrate the feasibility that a sparse electrode EEG configuration is capable of capturing well-defined ERP waveforms from living subjects under very challenging field conditions. While living subjects displayed well-defined MMN and ABR responses, no recognizable EEG waveforms were discernable in any of these tukdam cases.

Genetic predispositions may make some children more likely to start musical training early; they may be encouraged by other people who recognize their talent

Why Is an Early Start of Training Related to Musical Skills in Adulthood? A Genetically Informative Study. Laura W. Wesseldijk, Miriam A. Mosing, Fredrik Ullén. Psychological Science, December 14, 2020. https://doi.org/10.1177/0956797620959014

Abstract: Experts in domains such as music or sports often start training early. It has been suggested that this may reflect a sensitive period in childhood for skill acquisition. However, it could be that familial factors (e.g., genetics) contribute to the association. Here, we examined the effect of age of onset of musical training on musical aptitude and achievement in professional musicians (n = 310) and twins (n = 7,786). In line with previous literature, results showed that an earlier age of onset was associated with higher aptitude and achievement in both samples. After we adjusted for lifetime practice hours, age of onset was associated only with aptitude (p < .001; achievement: p > .14). Twin analyses showed that the association with aptitude was fully explained by familial factors. Thus, these findings provide little support for a sensitive period for music but highlight that familiar factors play an important role for associations between age of onset of training and skills in adulthood.

Keywords: sensitive period, musical training, musical expertise, twins, professional musicians

Discussion

Here, we examined whether musical training at a younger age leads to higher levels of musical expertise when controlling for the effects of total practice and familial factors, as would be predicted from the hypothesis that there is a sensitive period for musical training in childhood. In both professional musicians and twins, an earlier age of onset of musical training was associated with higher aptitude and achievement. However, when we controlled for lifetime practice, associations between age of onset and achievement became insignificant, whereas age of onset still predicted aptitude. The latter association disappeared, in turn, when we controlled for familial liability in a cotwin control design. Further twin analyses showed that the associations between age of onset of musical training and musical aptitude and between age of onset and musical achievement were fully explained by familial factors (i.e., shared genetic and shared environmental factors), in line with our cotwin control findings.

In both samples, an earlier age of onset of musical training was associated with higher musical aptitude and musical achievement, but when analyses controlled for lifetime practice, age of onset significantly predicted only higher levels of musical aptitude. Whereas this highlights the importance of adjusting for lifetime practice when exploring the above associations, it also lends further support to the findings of associations between age of onset of musical training and performance on some musical tasks reported in earlier studies (Bailey & Penhune, 2010, 2012, 2013; Bailey et al., 2014; Ireland et al., 2019; Skoe & Kraus, 2013; Steele et al., 2013; Vaquero et al., 2016; Watanabe et al., 2007). The consistency across our two samples, a professional-musician and population-based twin sample, strengthens these findings and suggests a similar effect of age of onset of musical training in a wide range of musical expertise. More importantly, our findings suggest a mediating effect of total practice on the relationship between age of onset of musical training and musical achievement but not on musical aptitude. Importantly, cumulative lifetime practice has been shown to be influenced by genetic factors (Mosing et al., 2014) and therefore does not reflect only unique environmental influences. Further, in both samples, age of onset of musical training significantly predicted higher levels of pitch discrimination but not rhythm discrimination. Only in the population-based sample did an earlier age of onset predict higher levels of melody discrimination. This is in line with the finding by Ireland and colleagues (2019) that children who received musical training before the age of 7 years outperformed children who started later on simple melody discrimination but not complex rhythm synchronization. Last, when we treated age of onset as a binary variable to test for an age window of below and at or above 8 years old, our findings remained the same.

The twin sample allowed us to extend our analyses to control for familial confounding, thereby further investigating causality, as well as to estimate the influence of genetic, shared environmental, and nonshared environmental factors on age of onset of musical training and its relationship with expertise. The twin analyses provided no evidence for a causal effect of early training in such associations. First, we found the association between age of onset of musical training (continuous or binary) and musical aptitude or achievement to diminish (close to zero) when controlling for familial liability. Further, the associations were fully explained by familial factors (i.e., common genetic and shared environmental). Because unique environmental factors did not play a role in the association between age of onset of musical training and musical expertise, the data provide little support for a causal association. We wish to emphasize that these findings do not necessarily rule out the existence of a sensitive period. Importantly, however, our findings provide clear evidence for the importance of shared familiar factors in associations between age of onset and adult performance.

As mentioned before, genetic predispositions may make some children more likely to start musical training early. They may be encouraged by other people who recognize their talent and may to a higher degree seek out, show interest in, and have access to a musical environment. More musical parents may not only pass their genetic predisposition to their children but also provide both access to early musical training and a musically enriched childhood environment that enhances musical expertise. This is an example of gene–environment correlation, in which genetics and shared environmental factors may influence the association between age of onset of musical training and later expertise. For future research, children-of-twins and adoption studies are genetically informative designs that offer possibilities to further explore gene–environment correlation.

There are some limitations of this study. First, age of onset of musical training was self-reported, which may introduce a rater or recall bias. Another possibility is that parents who are aware that their children are monozygotic twins treat them more similarly compared with parents of dizygotic twins with regard to early musical training. This would mean a violation of the equal-environment assumption (i.e., that, on average, both monozygotic and dizygotic twins are treated equally similarly), also causing an upward bias in the heritability estimates. Although we were not able to control for this in our study, multiple earlier studies have shown that the assumption generally holds (Derks, Dolan, & Boomsma, 2006). The absence of an effect of age of onset of musical training on rhythm discrimination in professional musicians should be interpreted with caution because strong ceiling effects were found in the musician sample on this subtest. Last, we note that the mean age of onset is significantly higher in male than in female participants. However, additional regression analyses separately for sex did not change the findings. One major strength of this study is the availability of both a professional musician sample and a large population-based twin sample. This allowed us to fully explore the association between age of onset of musical training and musical expertise while controlling for confounds between genetic and shared environmental factors.

The present study is, to our knowledge, the largest and only genetically informative study to focus on whether starting musical training at a younger age leads to higher levels of musical expertise. When controlling for lifetime practice, we found that an earlier age of onset of musical training predicted higher levels of musical aptitude in adulthood in professional musicians and in the general population. However, the association diminished when analyses controlled for familial liability in a cotwin control design. This, together with the finding that the association between age of onset of musical training and musical aptitude was fully explained by familial factors, suggests that a genetic predisposition for music may make children start musical training at a younger age. Thus, our findings provide little direct support that early training has a specific, causal effect on later performance and achievement; rather, they highlight the importance of taking into account cumulative measures of practice as well as genetic and shared environmental factors when studying sensitive periods and effects of an early age of onset of musical training on expertise in later life.

Some participants described sexual boredom as feeling obligated to engage in undesired sexual acts

Perceptions of sexual boredom in a community sample. Leonor de Oliveira,Joana Carvalho & Pedro Nobre. Journal of Sex & Marital Therapy, Dec 8 2020. https://doi.org/10.1080/0092623X.2020.1854405

Abstract: This study explored the definitions of sexual boredom in a large community sample of Portuguese individuals. A thematic analysis of written responses to the question “What is sexual boredom for you?” was conducted with 653 participants aged 18 to 75 (M = 33.14; SD = 9.01) of multiple genders, sexual orientations, and relationship types. Three main themes were identified: definitions of sexual boredom, predisposing and maintenance factors of sexual boredom, and managing of sexual boredom. Sexual monotony, sexual desire, and hedonic value stand out as defining features of sexual boredom. Findings suggest the need of a multidimensional measure of sexual boredom.

Discussion

This thematic analysis identified diverse definitions of sexual boredom, as well as individual,

interpersonal, and practice-related factors involved, and, finally, management paths.

Participants frequently defined sexual boredom with aspects of sexual monotony, lack of sexual

desire and lack of hedonic value. Monotony is a core feature of general boredom (Fenichel, 1951;

Geiwitz, 1966; Perkins & Hill, 1985; Zuckerman, 1979) and research verified that monotonous

stimuli led to decreases in judged hedonic value (Berlyne, 1970). Sexual monotony is central to

the definition of sexual boredom (Watt & Ewing, 1996), which was negatively correlated with sexual

satisfaction and sexual desire (Carvalheira et al., 2014;
Stulhofer et al., 2010).

Some participants described sexual boredom as feeling obligated to engage in undesired sexual

acts. We are unaware of similar findings in previous research. In the context of general boredom,

research concluded that boredom is a function of the level of effort required to attend to stimuli

that are not intrinsically captivating (Leary et al., 1986; Mikulas & Vodanovich, 1993). Being

bored with an obligation in a more mundane situation may not cause much distress, however

this might not be the case for mandatory sex.

In addition, participants identified sexual boredom could be a result of having sex with the

same partner. These findings may be partially explained by the sexual strategies theory (Buss &

Schmitt, 1993) that postulates sexual boredom in males restores mating behavior in the presence

of novel females (see Dewsbury, 1981). According to this view, desire for sexual variety is not

observed in women (Buss & Schmitt, 1993; Schmitt et al., 2001), but our study suggests sexual

boredom linked to having sex with the same partner is too found in women. Possibly, some

people, independently of gender, may have a non-monogamous orientation, which may be in the

genesis of their sexual boredom.

Our findings suggest sex frequency may also play a role in one’s assessment of sexual boredom.

Although no previous research addressed sexual boredom and sex frequency, some studies

reported sex frequency predicts sexual satisfaction in couples (e.g. Frederick et al., 2017; McNulty

et al., 2016; Schoenfeld et al., 2017). Further research is needed to determine if low sex frequency

can trigger or result in sexual boredom.

Finally, our research implies having low or no emotional connection with a sexual partner

may contribute to sexual boredom for some. There are no previous studies addressing this link,

although emotional connection to a sexual partner was found as an important component of

sexuality in long-term couples (Lemieux et al., 2004), friends with benefits (Lehmiller et al.,

2011), and individuals reporting having “great sex” (Kleinplatz & Menard, 2007).

Our findings highlight potential cognitive, emotional, and physical mechanisms of sexual boredom,

namely distraction, negative affect, and fatigue – all of which were previously related with

boredom proneness (Farmer & Sundberg, 1986; Malkovsky et al., 2012; Mercer-Lynn et al., 2014),

or with decreases in sexual desire (Maserejian et al., 2010; Murray et al., 2014). However, there is

no research on individual factors of sexual boredom we are aware of. This study indicates that

similarly to general boredom, sexual boredom may have relationships with attentional processes,

affect, and physical well-being. More importantly, it suggests sexual boredom is linked to personal

distress, emphasizing the need of further examining this construct as a sexual problem with

impact on sexual relationships.

In addition, our participants linked partner and relationship factors to sexual boredom.

Although we did not find research concerning partner factors in sexual boredom, some studies

indicate partners’ poor sexual skills impacted negatively sexual desire in women (Basson, 2001;

Brotto et al., 2011; Gehring, 2003), whilst partner responsiveness was positively associated with

sexual satisfaction in women and men (Vaillancourt-Morel et al., 2019). Within relationship factors,

were identified themes of lack of passion or eroticism, relationship issues, and duration of

relationship - which were previously related with decreases in sexual desire (Klusmann, 2002;

Murray et al., 2014; Murray & Milhausen, 2012; Sims & Meana, 2010). Only the studies of

Tunariu and Reavey (2003, 2007) explored relational aspects of sexual boredom, suggesting poor

sexual communication and relationship length could lead to sexual boredom.

Engaging in solitary practices and lack of sexual stimulation during partnered activity were

two reasons our participants related to sexual boredom. We know masturbation was related with

boredom (Gana et al., 2001), and sexual boredom (Carvalheira et al., 2015), but there seem to be

no studies regarding partnered sexual practices and sexual boredom. Moreover, several participants

reflected on a general sense of frustration stemming from sexual disappointment, as when

sex does not meet expectation. This could be in part related to the over-emphasis placed on sexual

variety and novelty (Tunariu & Reavey, 2007), which sets unrealistic expectations, and consequently

leads to frustration (Metz & McCarthy, 2011).

Several participants referred potential stages involved in managing sexual boredom. Some

mentioned acknowledging changing sex patterns allowed them identifying sexual boredom, while

others reflected on solutions to overcoming this, or identified potential constraints doing so.

Participants in this study named engaging in novel sexual behaviors (e.g. try new positions,

using sex toys, practicing BDSM, etc.) as potential solutions for overcoming sexual boredom.

Previous research suggested introducing sexual novelty to combat negative consequences of sexual

boredom could be helpful for couples in long-term monogamous relationships (Matthews

et al., 2018).

From the participants’ answers we also extracted some potential constraints, which may possibly

interfere with adopting new practices to fight sexual boredom, namely sexual beliefs and

ignorance of sexuality or one’s body. Research shows dysfunctional sexual beliefs play a role in

sexual dysfunction (Nobre & Pinto-Gouveia, 2006), and specifically in sexual desire in men and

women (Carvalho & Nobre, 2010, 2011). As well, poor sexual skills, such as unwillingness to integrate

the sexual skills necessary to uphold exciting sex, was postulated by Tunariu and Reavey

(2007) as a factor leading to the onset of sexual boredom. Our study adds evidence for the

importance of sexual education in managing sexual problems, an area of clinical intervention

with people with sexual difficulties for some time (Annon, 1976).

Limitations

This study aimed to explore definitions and dimensions of sexual boredom in a heterogeneous

sample of the community. Like many studies of sexuality, participants volunteering to take part

in the investigation may not resemble the general population in several aspects, especially in what

concerns openness to discuss sex related matters. Although our findings are not meant for generalization,

it is possible that they more closely reflect women’s sexual boredom, as they made up

most of our sample. In addition, the investigators responsible for the analysis were both women

psychologists, which may have also influenced the process. Another drawback of this study relates

to the potential influence of survey content on our participants’ answers to the open-ended item.

We are mindful that the participants’ attitudes and responses may have been primed having

answered questionnaires on some aspects of human sexuality before providing their definitions of

sexual boredom. This study did not assess intercoder reliability as, similarly to Braun and Clarke

(2019), we believe this would bear a positivist assumption there is a reality in the data that can

be accurately captured through coding. Our final coding matrix is purposely a simplification of a

complex construct and a product of these authors’ choices. While acknowledging this we also

stress the importance of rendering dimensions of sexual boredom intelligible, as most of the individual

and interpersonal aspects of sexual boredom were not yet known.
