The Dietary Behaviors of Participants in UK-Based meat reduction and vegan campaigns – A longitudinal, mixed-methods study. Trent Grassian. Appetite, June 26 2020, 104788. https://doi.org/10.1016/j.appet.2020.104788
Highlights
• Examination of dietary changes revealed reduction and abstention hierarchies that prioritize reducing/eliminating red meat consumption.
• Findings supports tendency toward gradual dietary changes.
• Planned abstainers (i.e. vegans and vegetarians) were more likely to meet dietary goals than were meat reducers.
• Increased consumption most commonly reported for seafood or eggs, least commonly for red meat.
Abstract: Meat reduction, vegetarianism, and veganism have greatly increased in popularity during the 21st century, particularly in the United Kingdom. Yet, little is known about the process of reducing or abstaining. Through the use of focus groups and a longitudinal, web-based survey delivered over a twelve-month period, this project provides insights into the reported dietary habits and trends of participants in UK-based meat reduction and vegan campaigns (n = 1539). Drawing on Michie, Atkins, et al. (2014) and Michie, West, et al. (2014)'s Behavior Change Wheel to better understand the process of dietary transition, findings reveal key opportunities for policymakers and non-profit organizations to better understand and support the process of dietary change. Reported planned dietary changes suggest a tendency for gradual transitions, with planned and achieved transitions generally reflecting proposed reduction and abstention hierarchies. Planned reductions were most likely to include red meat and least likely to include seafood or eggs, while seafood abstention was more common than that of dairy or eggs. Those seeking to abstain from the consumption of some or all animal-derived foods were the most likely to report meeting their anticipated dietary changes, while meat reducers were generally unlikely to indicate that they were achieving planned reductions.

Iceland: There is a difference between men and women when it comes to masturbation habits. Men masturbate much more frequently than women
Differences in masturbation habits among men and women in Iceland. Katrín Ragnarsdóttir. Reykjavík Univ., Psychology Dept, Jun 23 2020. http://hdl.handle.net/1946/36441
Abstract: This study examined differences in masturbation habits, including the frequency of masturbation and pornography use, amongst men and women in Iceland. Participants in the study were university students, 18 years of age and older, who answered an anonymous online questionnaire sent to their university email address. A total of 245 students participated; 126 males and 119 females. Most of the participants were married or in a relationship (N = 145) and 91.4% of the participants were heterosexual. For statistical analysis, a t-test, independent samples t-test and a chi-square test was used. The results of this study revealed that there is a difference between men and women when it comes to masturbation habits. Men masturbate much more frequently than women. However, majority of the participants had masturbated at some point in their lives.

Investigating whether some people desire a psychologically rich life more so than two well-established ideal lives: a happy life and a meaningful life
Happiness, Meaning, and Psychological Richness.

Abstract: What kind of life do people want? In psychology, a good life has typically been conceptualized in terms of either hedonic or eudaimonic well-being. We propose that psychological richness is another neglected aspect of what people consider a good life. In study 1 (9-nation cross-cultural study), we asked participants whether they ideally wanted a happy, a meaningful, or a psychologically rich life. Roughly 7 to 17% of participants chose the psychologically rich life. In study 2, we asked 1611 Americans and 680 Koreans what they regret most in their lives; then, if they could undo or reverse the regretful event, whether their lives would have been happier, more meaningful, or psychologically richer as a result. Roughly 28% of Americans and 35% of Koreans reported their lives would have been psychologically richer. Together, this work provides a foundation for the study of psychological richness as another dimension of a good life.

General Discussion
Recent research has found that a psychologically rich life is distinct from a happy or meaningful life in terms of personality predictors (Oishi et al., 2019), life experiences (Oishi, Choi, Heintzelman, et al., 2020), and political orientations Oishi, Westgate, Heintzelman, et al., 2020). We conducted the current research with the goal of investigating whether some people desire a psychologically rich life more so than two well-established ideal lives: a happy life and a meaningful life.
In study 1 (a 9-nation study), we found that most people’s self-described ideal lives were psychologically rich. When forced to choose, however, the majority favored a happy life (49.7 to 69.9%) or a meaningful life (14.2 to 38.5%). Even so, a substantial minority of participants still favored a psychologically rich life, even at the expense of a happy life or a meaningful life, ranging from 6.7% (Singapore) to 16.8% of participants (Germany). In studies 2a and 2b, we found that these numbers were even higher when desire for a psychologically rich life was measured indirectly. Roughly 28% of Americans and 35% of Koreans reported that their lives would have been psychologically richer, if they could undo the most regretted event of their lives. These data suggest that most people’s ideal lives are not just happy or meaningful but also psychologically rich, and that when forced to pick one, a non-trivial number of people desire a rich life more than a happy or a meaningful life. When measured indirectly, just as many people wish their lives were richer as do wish their lives were happier or more meaningful.
As discussed above, well-being research has been dominated by two concepts: hedonic and eudaimonic well-being (Diener et al., 1999; Vittersø, 2016). Our present research suggests a broader view. Namely, that a psychologically rich life is another type of a good life that some individuals lead and desire, and one that is not captured by current empirical conceptions of a good life. Importantly, unlike happiness or meaning, our conception of richness includes moments of discomfort and unpleasant emotion. Understanding that a good life may not always be pleasant or sacrificial—that there is value to individuals in leading lives that investigate truth, knowledge, and deep encounters with the world around them—may help us understand why people sometimes seek out such experiences (e.g., studying abroad, reading James Joyce’s Ulysses) at the expense of their own comfort and security. The ability to make sense of such behaviors is a benefit of conceptualizing a psychologically rich life as another type of a good life that people value and seek out.
Indeed, people with psychologically rich lives experience both positive and negative emotions more intensely, whereas those leading happy or meaningful lives experience positive emotions more intensely but negative emotions less intensely (Oishi, Westgate, Heintzelman, et al., 2020). It will be fruitful to explore how a psychologically rich life is associated with other important dimensions of emotional experiences such as the diversity of emotional experiences (Quoidbach et al., 2014), affect valuation (Tsai, 2007), and emotion differentiation and regulation (Barrett, Gross, Christensen, & Benvenuto, 2001).
Importantly, although we tested the relative importance of three types of the ideal life, we do not claim there cannot be others. Based on Schwartz’s (1992) value theory, Tamir and colleagues (Tamir et al., 2016; Tamir, Schwartz, Oishi, & Kim, 2017) recently examined four types of desired and experienced emotions: self-transcendence (e.g., love), self-enhancement (e.g., pride), openness (e.g., interest), and conservation (e.g., contentment). A psychologically rich life corresponds well to openness-related emotions, whereas a happy life corresponds well to conservation and self-enhancement emotions; a meaningful life appears to match well with self-transcendent emotions. Given that the literature suggests that there are at least 11 universal human values (Schwartz, 1992), and that values are guiding principles in life, there may be many more than the three ideal lives presented here.
We also acknowledge the limitations of the current research. Most critically, we did not examine the potential consequences of leading a psychologically rich life. It is crucial to test whether the consequences of a psychologically rich life are indeed different from a happy or meaningful life—and whether these consequences are a good thing. Second, while study 1 included diverse cross-cultural samples, study 2 was limited to the USA and Korea. It is important to explore what it means to live a psychologically rich life (and whether doing so is desirable) in other non-Western, non-democratic, relatively poor societies.
Men do not need attentional resources when processing female faces, but need them with male ones; in contrast, women need attentional resources to process the attractiveness of opposite as well as same-sex faces
Automaticity of facial attractiveness perception and sex-specific mating strategies. Lisa Klümper et al. Cognition, Volume 204, November 2020, 104379. https://doi.org/10.1016/j.cognition.2020.104379
Highlights
• The perception of facial attractiveness is not automatic (capacity-free) in general.
• Men show an automatic (capacity-free) processing of females' facial attractiveness but not of males' facial attractiveness.
• Women show no automatic (capacity-free) processing of males' or females' facial attractiveness.
• This pattern makes sense from an evolutionary perspective on different mating strategies of men and women.
Abstract: The current literature shows mixed results regarding whether the perception of facial attractiveness is automatic, i.e. that it operates independently from attentional resources. We argue that an evolutionary perspective on mating strategies provides a comprehensive account of the findings. In two studies, we used the locus-of-slack logic in a psychological refractory period paradigm. Task 1 was a speeded judgment of tone pitch (low vs. high), and Task 2 was a speeded judgment of whether a face was attractive or unattractive on two difficulty levels. Male and female participants judged the attractiveness of opposite-sex faces (Study 1, n = 73) or same-sex faces (Study 2, n = 94) in this paradigm. Results indicate that men do not need attentional resources when processing female faces (Study 1), but require attentional resources when processing same-sex faces (Study 2). In contrast, women need attentional resources to process the attractiveness of opposite as well as same-sex faces.

Conversations about experiences (vs. objects) are more substantive, allowing listeners to build stronger social connections with tellers and, in turn, gain more happiness from the interaction
Want to Make Me Happy? Tell Me about Your Experiences but Not Your Objects. Wilson Bastos. Journal of Consumer Affairs, June 22 2020. https://doi.org/10.1111/joca.12321
Abstract: Evidence indicates that experiences bring greater benefits to consumers than objects. Extending this research beyond the actual purchaser, this work examines individuals who experience the purchase only indirectly via a conversation—listeners. It explores how conversations about experiential versus material purchases affect listeners socially and emotionally. Results show that hearing about others’ experiences (vs. objects) advances listeners’ happiness more. This finding shows that the scope of experiential purchases’ advantage is wider than previously known. Further, this work identifies a sequential mechanism: Conversations about experiences (vs. objects) are more substantive, allowing listeners to build stronger social connections with tellers and, in turn, gain more happiness from the interaction. Critically, this mechanism explains the effect above and beyond a previously‐advanced mechanism via perceived motivation (Van Boven, Campbell, and Gilovich 2010). Additionally, this work identifies a boundary of the model: purchase valence. Theoretical and practical implications for managers, consumers, and policymakers are discussed.

Social media: More frequent & extreme upward comparisons resulted in immediate declines in self-evaluations as well as cumulative negative effects on individuals’ state self- esteem, mood, & life satisfaction
Midgley, Claire, Sabrina Thai, Penelope Lockwood, Chloe Kovacheff, and Elizabeth Page-Gould. 2020. “When Every Day Is a High School Reunion: Social Media Comparisons and Self-esteem.” PsyArXiv. June 26. doi:10.31234/osf.io/zmy29
Abstract: Although past research has shown that social comparisons made through social media contribute to negative outcomes, little is known about the nature of these comparisons (domains, direction, and extremity), variables that determine comparison outcomes (post valence, perceiver’s self- esteem), and how these comparisons differ from those made in other contexts (e.g., text messages, face-to-face interactions). In four studies (N=798), we provide the first comprehensive analysis of how individuals make and respond to social comparisons on social media, using comparisons made in real-time while browsing news feeds (Study 1), experimenter- generated comparisons (Study 2), and comparisons made on social media vs. in other contexts (Studies 3-4). More frequent and more extreme upward comparisons resulted in immediate declines in self-evaluations as well as cumulative negative effects on individuals’ state self- esteem, mood, and life satisfaction after a social media browsing session. Moreover, downward and lateral comparisons occurred less frequently and did little to mitigate upward comparisons’ negative effects. Furthermore, low self-esteem individuals were particularly vulnerable to making more frequent and more extreme upward comparisons on social media, which in turn threatened their already-lower self-evaluations. Finally, social media comparisons resulted in greater declines in self-evaluation than those made in other contexts. Together, these studies provide the first insights into the cumulative impact of multiple comparisons, clarify the role of self-esteem in online comparison processes, and demonstrate how the characteristics and impact of comparisons on social media differ from those made in other contexts.

Investors’ risk attitudes in the pandemic: Stock markets are less sensitive in jurisdictions that have restricted mobility less and that have enacted other containment measures against the pandemic
Investors’ risk attitudes in the pandemic and the stock market: new evidence based on internet searches. Marlene Amstad, Giulio Cornelli, Leonardo Gambacorta and Dora Xia. BIS Bulletin No. 25. https://www.bis.org/publ/bisbull25.htm
Key takeaways
• The sharp drop and subsequent rebound in global stock markets in the current pandemic focuses attention on changes in investors’ risk attitudes.
• A new Covid-19 risk attitude (CRA) index for 61 markets, based on internet searches in Google and Baidu, does a good job at capturing investors’ attitudes toward pandemic-related risks.
• Stock markets are more sensitive to changes in the CRA index in more financially developed economies. Stock markets are less sensitive in jurisdictions that have restricted mobility less and that have enacted other containment measures against the pandemic.
1. Introduction
The Covid-19 crisis has left a deep mark on stock markets, with a fall in prices similar to those experienced during the Great Depression in 1929, and a subsequent rebound. The observed equity price reaction relates to changes in traditional drivers such as relative price shifts and risk aversion measures, but it could also reflect changes in investors’ attitude towards risk in the pandemic.1 The aim of this Bulletin is to use information on internet searches on Google and Baidu to derive a measure of stock market investors’ concerns about the pandemic and to assess how such a measure could explain the sharp drop and subsequent rebound in stock markets. We focus on the initial period of the Covid-19 pandemic, covering up to end-April 2020.
The role of investors’ risk attitude could be particularly relevant in a time of sudden large shocks and when fundamental drivers suffer from higher uncertainty. The US Economic Policy Uncertainty index has peaked in April 2020 at levels more than twice as high as previous records (Baker et al (2020)). Shiller (2020) even sees Covid-19 as two pandemics – one in the real economy, and the other in the perception of the impact the first one might have. However, while the impact of fundamental drivers on US stock returns during the pandemic has already been studied (Ding et al (2020) and Alfaro et al (2020)), the role of investors’ risk attitudes has received less attention.
The analysis in this Bulletin focuses on mid-February to end-April 2020, including an initial period of severe sell-off in global equity markets (until mid-March), as well as a recovery – in some cases by almost half of the previous drop – from then to end-April. We show that traditional drivers of equity markets – such as changes in the value of the US dollar, oil prices, measures of risk aversion – and the unconventional monetary policy measures adopted are not able to fully capture the evolution of stock market prices during this period. To study the evolution of investors’ risk attitude towards the pandemic, we construct for each market a new “Covid-19 risk attitude” (CRA) index, based on the number of internet searches in different markets. The idea is that web searches for terms related to Covid-19 reflect people’s concern about the pandemic and its economic consequences. Interestingly, during the first months of the pandemic the CRA index foreshadowed the actual number of recorded infections globally. This indicates that for investors the economic effects of the pandemic are globally linked and are not confined to the areas directly affected by the virus. From the last week of March until the end of April, a fall in the CRA index reflects a reduction in investors’ concern and goes hand in hand with the recovery in equity prices.
Results indicate that investors’ risk attitude as captured by internet searches played a significant role in most stock markets over and above what is explained by other more traditional drivers. On average, the CRA index explains an additional 6% of the observed equity price variation in the sample period.2 In particular, stock markets are more sensitive to changes in the CRA index in more financially developed economies. Markets are less sensitive in those jurisdictions that have restricted mobility by less and have enacted other containment measures against the pandemic.

Defensive states driving active escape from immediate danger also facilitate decisions to help others, potentially by engaging neurocognitive systems implicated in caregiving across mammals
Vieira, Joana, Sabine Schellhaas, Erik Enström, and Andreas Olsson. 2020. “Help or Flight? Increased Threat Imminence Promotes Defensive Helping in Humans.” PsyArXiv. May 17. doi:10.31234/osf.io/bckn3
Abstract
Defensive responses to threatening situations vary with threat imminence, but it is unknown how those responses affect decisions to help others. Here, we manipulated threat imminence to investigate the impact of different defensive states on helping behaviour. Ninety-eight participants made trial-by-trial decisions about whether to help a co-participant avoid an aversive shock, at the risk of receiving a shock themselves. Helping decisions were prompted under imminent or distal threat, based on temporal distance to the moment of shock administration to the co-participant. Results showed that, regardless of how likely participants were to also receive a shock, they helped the co-participant more under imminent than distal threat. Individual differences in empathic concern were specifically correlated with helping during imminent threats. These results suggest defensive states driving active escape from immediate danger also facilitate decisions to help others, potentially by engaging neurocognitive systems implicated in caregiving across mammals.

Polite Speech Emerges from Competing Social Goals
Yoon, Erica J., Michael C. Frank, Michael H. Tessler, and Noah D. Goodman. 2018. “Polite Speech Emerges from Competing Social Goals.” PsyArXiv. December 29. doi:10.31234/osf.io/67ne8
Language is a remarkably efficient tool for transmitting information. Yet human speakers make statements that are inefficient, imprecise, or even contrary to their own beliefs, all in the service of being polite. What rational machinery underlies polite language use? Here, we show that polite speech emerges from the competition of three communicative goals: to convey information, to be kind, and to present oneself in a good light. We formalize this goal tradeoff using a probabilistic model of utterance production, which predicts human utterance choices in socially-sensitive situations with high quantitative accuracy, and we show that our full model is superior to its variants with subsets of the three goals. This utility-theoretic approach to speech acts takes a step towards explaining the richness and subtlety of social language use.

Computational Modeling of Backwards-blocking Reasoning in Human Adults
Benton, Deon T., and David H. Rakison. 2020. “Computational Modeling of Backwards-blocking Reasoning in Human Adults.” PsyArXiv. May 27. doi:10.31234/osf.io/xq8ws
Causal reasoning is a fundamental cognitive ability that enables humans to learn about the complex interactions in the world around them. However, it remains unknown whether causal reasoning is underpinned by a Bayesian mechanism or an associative one. For example, some maintain that a Bayesian mechanism underpins human causal reasoning because it can better account for backward-blocking (BB) and indirect screening-off (IS) findings than certain associative models. However, the evidence is mixed about the extent to which learners engage in both kinds of reasoning. Here, we report an experiment and several computational models that examine to what extent adults engage in BB and IS reasoning using the blicket-detector design. The results revealed that adults’ causal ratings in a backwards-blocking and indirect screening-off condition were consistent with associative rather than a Bayesian computational model. These results are interpreted to mean that adults use associative processes to reason about causal events.

Seeing Our 3D World While Only Viewing Contour-drawings
Farshchi, Maddex, Alexandra Kiba, and Tadamasa Sawada. 2020. “Seeing Our 3D World While Only Viewing Contour-drawings.” PsyArXiv. June 25. doi:10.31234/osf.io/28wmp
Abstract: Artists can represent a 3D object by using only contours in a 2D drawing. Prior studies have shown that people can use such drawings to perceive 3D shapes reliably, but it is not clear how useful this kind of contour information actually is in a real dynamical scene in which people interact with objects. To address this issue, we developed an Augmented Reality (AR) device that can show a participant a contour-drawing of a real dynamical scene in an immersive manner. We found that contour information, alone, is sufficient to perform a variety of run-of-the-mill tasks under natural viewing conditions. This contour information may be sufficient to provide the basis for our visual system to obtain all of the 3D information needed for successful visuomotor interactions in our everyday life.
Abstract: Artists can represent a 3D object by using only contours in a 2D drawing. Prior studies have shown that people can use such drawings to perceive 3D shapes reliably, but it is not clear how useful this kind of contour information actually is in a real dynamical scene in which people interact with objects. To address this issue, we developed an Augmented Reality (AR) device that can show a participant a contour-drawing of a real dynamical scene in an immersive manner. We found that contour information, alone, is sufficient to perform a variety of run-of-the-mill tasks under natural viewing conditions. This contour information may be sufficient to provide the basis for our visual system to obtain all of the 3D information needed for successful visuomotor interactions in our everyday life.
Illusory Snakes Might Be Due to Asynchronized Respective Field Remapping
Yousef, Ahmad. 2019. “Illusory Snakes Might Be Due to Asynchronized Respective Field Remapping.” PsyArXiv. June 19. doi:10.31234/osf.io/ve4s8
Abstract: In this proposal, we try to virtually navigate inside the human brain to understand the neural mechanism of the perception of illusory snakes. To achieve this mission, we have to imagine the neural network of visual motion perception during spontaneous saccadic eye movements. We had previously discussed that conscious perception generated by the central retina has very different attributes than the visual awareness generated by the peripheral retina. It was clear that the central retina trigger visual perception which decelerates the apparent motion of the cyclic elements, and enlarge the size of these elements, see reference 2. The peripheral retina , however, not only accelerates the apparent motion, but it generates illusory motion reversals, see reference 19. Since there are clear discrepancies in the spatiotemporal characteristics between the central and the peripheral retina in the visual awareness, we hypothesized that the illusory rotating snakes might be due to asynchronized respective field remapping. Namely, the respective field remapping of the central retina has different spatial and temporal feeds to the visual awareness than the retinal peripheries. Interestingly, it had been found that deactivating the retinal peripheries through significant reduction against the contrast of the stimulus (that may stop the retinal peripheries from signaling the brain) eliminates the rotating snakes illusion. Elimination that might evidence the role of active retinal peripheries in creating the perception of illusory snakes. Collectively, we think that illusory snakes is due to a rivalry between the central and the peripheral retina; and their corresponding conscious brains; and the saccades are nothing but to convey parts of the retinal image from the center to the peripheries, and vice versa. Namely, the illusory snakes is generated by a spontaneous saccadic rivalry between the fovea & its corresponding conscious brain competing with the peripheral retina & its corresponding conscious brain. Similarly, peripheral drift illusion that requires peripheral vision to be perceived, may not be generated without the aforementioned saccadic rivalry; namely, we think that the perception of that illusion may not be occurred without spontaneous saccade away from the fixational peripheral visual space, see also reference 1 and 5. That saccade is mostly due to spatial attention which conveys the retinal image from the retinal peripheries (the fixational visual space) to the central retina (the attentional visual space). Namely, we think that without the aforementioned conveyance, the perceived illusion may not be generated because the aforementioned spatiotemporal discrepancies will be terminated. Importantly, we discuss the contribution of the human medial temporal complex in producing the illusory motion conscious perception with three different mechanisms: Cognitive control, deep breathing, and the arrangements of the patterns of the building blocks. The aforementioned processes are found to alter the visual perception of rotating snakes stimulus. Inclusively, we distinguish between two distinct visual awareness, namely, the central versus the peripheral visual and we show how active vision which requires cognitive control but not passive vision can ultimate control the perception the rotating snakes stimulus, namely, alternation between real and illusory visual awareness!

Effects of the characteristic temperament of cats on the emotions and hemodynamic responses of humans
Effects of the characteristic temperament of cats on the emotions and hemodynamic responses of humans. Takumi Nagasawa,Mitsuaki Ohta,Hidehiko Uchiyama. PLoS One, June 25, 2020. https://doi.org/10.1371/journal.pone.0235188
Abstract: Cats positive effects on their owners’ physiological and psychological health, including improved mood and activation of the human prefrontal cortex and inferior frontal gyrus in the brain. However, the association between the health benefits provided by cat ownership and the characteristic behaviors and reactions of cats is unclear. We recruited 29 participants to measure human prefrontal cortex activity, using functional near-infrared spectroscopy, during interactions with a cat. After the experiments, participants subjectively responded to a questionnaire regarding success rates for interactions with the cat, and completed the Self-assessment Manikin—a scale used to measure emotion. Interactions comprised eight types in four categories (touch, play, train, and feed). This study showed that interactions with a cat significantly activated the prefrontal cortex, regardless of interaction type. During training, the integral values of oxygenated hemoglobin in the left inferior frontal gyrus were the highest in all the interaction categories; however, success rates were lower than in the touch and feed interactions. Regarding the Self-assessment Manikin scores, all interaction categories showed a positive correlation between success rate and valence score, especially in the train and play interactions than in the touch and feed interactions. These results indicate that interactions with a cat activate the prefrontal cortex in humans, including the inferior frontal gyrus region. Moreover, cats’ autonomous behaviors and reactions positively influenced the participants. The characteristic temperament of cats may be a key factor influencing the health benefits of owning cats.

Discussion
Sequential change in Oxy-Hb signal of the PFC
Interactions with a cat activated participants’ PFC, regardless of interaction type. The experiment protocol consisted of interactions typical in cat owners’ homes; therefore, this result suggested that owning a cat enhances the function of the owners’ PFC. Furthermore, PFC controls executive function [12]; therefore, interactions with a cat may improve executive function. This result is consistent with previous studies [10][11]. To our knowledge, this study may be one of the first to explain the mechanism that everyday interaction with cats enhance PFC function.
Integral values of the IFG for the train and play interactions
We focused on the integral values of Oxy-Hb signals in left and right IFG regions. In all interactions, the integral values did not correlate with each success rate individually. However, there was a significant difference among interaction categories. The integral values of the train interaction were larger than those of the other interaction categories. Notably, in the left IFG region, the integral values of the train interaction were significantly larger than those of the other categories. The left IFG controls the mirror neuron system [36] and empathy [37]. This study suggested that performing training interactions with a cat would be an effective way to help develop these brain functions.
There are several possible reasons for significant activation of the IFG during the train interaction. First, participants might have not been accustomed to training a cat; thus, it is possible that unnatural interaction situation promoted Oxy-Hb activation for participants. Training is still not a typical interaction between a cat and its owner in general households. Nevertheless, training using clicker has recently become a standard method to improve cats’ welfare [20] and develop effective relationships between cats and humans [38]. Training a cat should be recognized as a common interaction between cats and their owners.
Second, the characteristic temperament of cats (i.e., not typically displaying obedient behavior) might have been the reason for activation of the IFG. For the train interaction, participants reported significantly lower success rates than for the feed and touch interactions. The cat frequently showed autonomous behaviors and reactions to participants owing to the independent nature of cats. Participants might try to anticipate the cat’s next action and determine how to succeed. This thinking process might have been the reason for the activation of the IFG.
The play interaction also showed a lower success rate than did the feed and touch interactions. Further, the integral values of the IFG during playing with the cat were larger than those during feeding. In the play interaction, it was difficult for participants to attract the cat to play. As with the train interaction, participants might think about the way to succeed in this interaction.
The thinking processes used during the train and play interactions related to fundamental nonverbal communication skills necessary not only for interactions between people and animals but also for interpersonal interactions. Therefore, the train and play interactions with a cat, which induce the activation of the IFG, have potential to treat individuals with ASD, which have impaired function in the IFG region [18]. Previous studies showed that interactions with an animal can improve the social communication skills of children with ASD [39][40]. Although much of the previous research has been performed using therapy dogs [41], a few studies have posited that cats can also be useful for therapy with people with ASD [42][43]. However, the mechanism was still unclear.
It is frequently difficult to speculate on cats’ behaviors, even for their owners. The behaviors and temperament of cats, such as independence, is a unique trait compared to dogs. As cat domestication was shorter than for dogs, and may not even be complete [28], the genes of domestic cats are not distinct from those of wild cats [44]; thus, even household cats frequently display autonomous behaviors like wild animals. The present results suggest that cats’ unique behaviors and reactions are the key factors explaining the mechanism underlying the health benefits that cats can provide to individuals with ASD. However, this study targeted healthy participants, not those with ASD; therefore, further studies are needed to determine whether cats positively effects the treatment of individuals with ASD.
Integral values of the IFG for the feed and touch interactions
During the feed interaction, the integral values were significantly less compared to the other interaction types; however, the success rate was higher than in the train and play interactions. Since feeding is the most fundamental interaction between a human and an animal, the cat relatively obeyed participants during the feed interaction. Participants may have felt it was easy to speculate on the cat’s behavioral reactions during the feed interaction; therefore, the IFG region was not activated.
As with feeding, tactile communication with a cat is a central interaction between a cat and its owner. In this study, the touch interaction showed a higher success rate than either the train or the play interaction; however, the integral values of the IFG were larger than during the feed interaction. This could be the result of tactile stimulation. A previous study showed that the IFG region was activated by touching a cat [13], which is consistent with the findings of this study. Therefore, the current results might show that tactile stimuli, which occur through interaction with a cat, affect IFG activation.
SAM
Valence scores from the SAM significantly positively correlated with success rates. The valence dimension in the SAM is the measurement of emotions, such as happiness and satisfaction [32]. In this study, participants felt positive emotion when the cat obeyed them. Moreover, the train and play interactions, which had a significantly lower success rate than the feed and touch interactions, showed a relatively higher correlation coefficient than the feed and touch interactions. Therefore, the present result indicates that the lower the success rate of interaction with a cat, the more likely positive emotions of the participants occurred when the interaction succeeds. As mentioned above, cats and dogs have different temperaments, and cats frequently showed autonomous behavior and reaction for their owners. These characteristic temperaments of cats may be the key factor to enhance human psychological status.
During the play interaction, only the arousal score for the SAM significantly positively correlated with success rates. The arousal dimension in the SAM is the measurement of emotions such as excitement [32]. In the play interaction, the success meant the cat responded to the cat toys using its paws. It is possible that the movement of the cat increased the arousal of the participants. Previous studies claimed that the arousal response is related to enhanced cognitive function [45]. Additionally, exercise, which increases arousal, also improves executive function [46][47]. Therefore, playing with a cat may promotes the development of human cognitive function. Furthermore, 90% of cat owners play with their cats at least once per day [48]; thus, play with cats is a common interaction for their owners. The results of the current study may show the mechanism of an association between owning pets and improved executive functions.
Limitations
This study had several limitations. First, we used a laboratory cat, not a house cat. This was because of the difficulty of conducting this experiment in cat owners’ homes. Domestic cats are territorial animals [49], and would not behave typically with their owner if an unfamiliar person and apparatus were to be in their territory. Thus, we utilized a laboratory cat. However, the cat had been raised in the laboratory like as a house cat; therefore, the cat had the characteristic temperament of a house cat.
Second, during the experiments, only participants could initiate an interaction, not the cat. Specifically, in the touch interactions, we requested that participants pet the cat. However, cats often display allogrooming (i.e., groom other cats using their tongue) and allorubbing (i.e., rubbing their head and tail toward other cats) behaviors toward humans [50]. If interactions between participants and the cat had been mutual, the results may have varied. In future studies, researchers should design a protocol that allows for free and mutual interactions between cats and participants.
Third, we used Bonferroni’s and Scheffe’s methods for post-hoc analyses; although, we did not use a false discovery rate approach. Therefore, further studies should use false discovery rate to control the proportion of false positives among channels that are significantly detected.
More than smell – COVID-19 is associated with severe impairment of smell, taste, and chemesthesis
More than smell – COVID-19 is associated with severe impairment of smell, taste, and chemesthesis. Valentina Parma et al. Chemical Senses, bjaa041, Jun 20 2020. https://doi.org/10.1093/chemse/bjaa041
Abstract: Recent anecdotal and scientific reports have provided evidence of a link between COVID-19 and chemosensory impairments such as anosmia. However, these reports have downplayed or failed to distinguish potential effects on taste, ignored chemesthesis, and generally lacked quantitative measurements. Here, we report the development, implementation and initial results of a multi-lingual, international questionnaire to assess self-reported quantity and quality of perception in three distinct chemosensory modalities (smell, taste, and chemesthesis) before and during COVID-19. In the first 11 days after questionnaire launch, 4039 participants (2913 women, 1118 men, 8 other, ages 19-79) reported a COVID-19 diagnosis either via laboratory tests or clinical assessment. Importantly, smell, taste and chemesthetic function were each significantly reduced compared to their status before the disease. Difference scores (maximum possible change ±100) revealed a mean reduction of smell (-79.7 ± 28.7, mean ± SD), taste (-69.0 ± 32.6), and chemesthetic (-37.3 ± 36.2) function during COVID-19. Qualitative changes in olfactory ability (parosmia and phantosmia) were relatively rare and correlated with smell loss. Importantly, perceived nasal obstruction did not account for smell loss. Furthermore, chemosensory impairments were similar between participants in the laboratory test and clinical assessment groups. These results show that COVID-19-associated chemosensory impairment is not limited to smell, but also affects taste and chemesthesis. The multimodal impact of COVID-19 and lack of perceived nasal obstruction suggest that SARS-CoV-2 infection may disrupt sensory-neural mechanisms.

Advancing science or advancing careers? Researchers’ opinions on success indicators
Advancing science or advancing careers? Researchers’ opinions on success indicators. Noémie Aubert Bonn, Wim Pinxten. bioRxiv Jun 23 2020. https://doi.org/10.1101/2020.06.22.165654
Abstract: The way in which we assess researchers has been under the radar in the past few years. Critics argue that current research assessments focus on productivity and that they increase unhealthy pressures on scientists. Yet, the precise ways in which assessments should change is still open for debate. We circulated a survey with Flemish researchers to understand how they work, and how they would rate the relevance of specific indicators used in research assessments. We found that most researchers worked far beyond their expected working schedule. We also found that, although they spent most of their time doing research, respondents wished they could dedicate more time to it and less time to other activities such as administrative duties and meetings. When looking at success indicators, we found that indicators related to openness, transparency, quality, and innovation were perceived as highly important in advancing science, but as relatively overlooked in career advancement. Conversely, indicators which denoted of prestige and competition were generally rated as important to career advancement, but irrelevant or even detrimental in advancing science. Open comments from respondents further revealed that, although indicators which indicate openness, transparency, and quality (e.g., publishing open access, publishing negative findings, sharing data, etc.) should ultimately be valued more in research assessments, the resources and support currently in place were insufficient to allow researchers to endorse such practices. In other words, current research assessments are inadequate and ignore practices which are essential in contributing to the advancement of science. Yet, before we change the way in which researchers are being assessed, supporting infrastructures must be put in place to ensure that researchers are able to commit to the activities that may benefit the advancement of science.

Overall, the present results indicate that fertility appears to be an important cue for perceived physical attractiveness for both hetero- and homosexual men
Fertility as a cue for attractiveness in homo- and heterosexual men. Robin Rinn et al Personality and Individual Differences, Volume 166, 1 November 2020, 110171. https://doi.org/10.1016/j.paid.2020.110171
Highlights
• Sexual Strategy Theory predicts that men prefer highly fertile women.
• Findings confirm: heterosexual men evaluate highly fertile women as most attractive.
• Homosexual men find both highly over lowly fertile women and men more attractive.
• Mating strategies seem to be closely tied to biological sex not to sexual orientation.
Abstract: According to the sexual strategy theory (SST), men pursue short-term mating strategies to enhance their reproductive fitness. To do so, heterosexual men search for women who signal high reproductive value through multiple fertility cues. We hypothesize that, due to an interplay of mating strategies derived from a person's biological sex and the sexual orientation of a person (which develops independently of biological sex), not only heterosexual but also homosexual men should find high fertility more attractive in others. Accordingly, in Study 1 (N = 124), we found that hetero- as well as homosexual men rated the physical attractiveness of a female stimulus person to be greater when she was portrayed to be of high (versus low) fertility. Interestingly, in Study 2 (N = 224), we found that only homosexual-, but not heterosexual men perceived a male stimulus to be less attractive when information was provided that pointed at his low (versus high) fertility and when no information was given. We discuss these findings against the background of evolved adaptive mating motives in humans. Overall, the present results indicate that fertility appears to be an important cue for perceived physical attractiveness for both hetero- and homosexual men.

From 2016... Is subversive or feminist the increasing consumption of pornographic content by women in contemporary Japan?
From 2016... Alexandra Hambleton: When women watch: the subversive potential of female-friendly pornography in Japan, Porn Studies, 3:4, 427-442, http://dx.doi.org/10.1080/23268743.2015.1065203
Abstract: Pornography producers in Japan are finding themselves increasingly struggling to maintain profits as free content becomes ever more easily available online. Within this environment, one niche area is bucking trends and increasing sales – pornography for women. In an industry where a DVD that sells 3000 copies is considered a hit, female-friendly pornography company Silk Labo has been able to not only produce DVDs which sell over 10,000 copies, but also generate publicity about the company and its aims which reaches far beyond neighbourhood DVD rental stores, and contributes to a wider conversation about women, sex, and pleasure in Japan today. This article draws on ethnographic fieldwork, interviews, and critical analysis of Silk Labo films to understand the phenomenon of increasing consumption of pornographic content by women in contemporary Japan, and asks whether the phenomenon is subversive or feminist.
Conclusions
Much as fandom and following pop idols acts as an escape from mundane life for many fans in Japan today (see Galbraith and Karlin 2012), participating in Silk Labo events allows fans of the company’s eromen idols an escape into a fantasy world in which sex is always with an attractive, caring man. The references to popular culture and pornography, and the in-jokes relied upon by Silk Labo are all indicative of its ability to provide an arena for them to engage in fan behaviour.
It is possible to argue that Silk Labo is one example of attempts to control female desires, redirected in such a way as to allow freedom within clearly demarcated heteronormative lines. From a queer studies perspective, Bronski argues that the process of ‘social containment, presenting less threatening forms of social change through commodification’ developed because people both desired and feared new freedoms, viewing them as a threat to the existing social order (2000, 69–70). In the case of host clubs, male sexuality is commodified and Japanese women deploy men as ‘resources’ to create a more woman-friendly lifestyle (Takeyama 2005, 200). As Takeyama argues, this ‘serves as an effective stimulus for women’s greater consumption, while also reinscribing gendered characteristics and hierarchical relations’ (2005, 200). The Silk Labo phenomenon similarly encourages consumption, but it also creates what Gordon (1992, 194) terms ‘the other place’, an arena in which female desire can be manipulated and controlled, and prevented from bleeding into surrounding arenas. However, while Silk Labo’s films may be problematic in many ways, they also offer a chance to move beyond traditional ideas of pornography as a male genre, and create the opportunity for further discussion about what it means to enjoy sex and one’s own sexuality for women in Japan today.
A year after my fieldwork I returned to the Silk Labo set in April 2014 and spent the day watching the cast and crew at work. Makino was still running the show but with a number of younger female crew learning to write, produce, and direct under her tutelage, women who often pour their own sexual fantasies into their productions. Since introducing mobile phone-streaming services earlier in the year, the company had been able to expand its reach, but was also under threat from new management at SOD who believed they could attract more female customers by dumping cheaply produced content onto cute websites under the heading of ‘female-friendly pornography’ and hoping audiences would graduate to purchasing full-length mainstream SOD movies. Having spent many years developing the Silk Labo brand, Makino was frustrated with this approach. However, as Silk Labo’s newest staff rushed to provide the cast with bathrobes after each scene and the crew munched on doughnuts as they revised the script, I realized that, despite constantly facing new challenges, for now at least Silk Labo may be responding to a new generation of women willing to try something different within the pornography industry, and that the quiet boom in female-friendly porn for women might yet spur a quiet revolution.

Since introducing mobile phone-streaming services earlier in the year, the company had been able to expand its reach, but was also under threat from new management at SOD who believed they could attract more female customers by dumping cheaply produced content onto cute websites under the heading of ‘female-friendly pornography’ and hoping audiences would graduate to purchasing full-length mainstream SOD movies. Having spent many years developing the Silk Labo brand, Makino was frustrated with this approach. However, as Silk Labo’s newest staff rushed to provide the cast with bathrobes after each scene and the crew munched on doughnuts as they revised the script, I realized that, despite constantly facing new challenges, for now at least Silk Labo may be responding to a new generation of women willing to try something different within the pornography industry, and that the quiet boom in female-friendly porn for women might yet spur a quiet revolution.

Poker is a game of skill and chance involving economic decision-making under uncertainty, with a strong potential as a model system for studying high-stakes, high-risk expert performance
Poker as a Domain of Expertise. Jussi Palomäki, Michael Laakasuo, Benjamin Ultan Cowley, and Otto Lappi. Journal of Expertise, Vol. 3(2). Jun 2020. https://www.journalofexpertise.org/articles/volume3_issue2/JoE_3_2_Palomaki_etal.html
Abstract: Poker is a game of skill and chance involving economic decision-making under uncertainty. It is also a complex but well-defined real-world environment with a clear rule-structure. As such, poker has strong potential as a model system for studying high-stakes, high-risk expert performance. Poker has been increasingly used as a tool to study decision-making and learning, as well as emotion self-regulation. In this review, we discuss how these studies have begun to inform us about the interaction between emotions and technical skill, and how expertise develops and depends on these two factors. Expertise in poker critically requires both mastery of the technical aspects of the game, and proficiency in emotion regulation; poker thus offers a good environment for studying these skills in controlled experimental settings of high external validity. We conclude by suggesting ideas for future research on expertise, with new insights provided by poker.

Respondents rated photographs of patients with facial paralysis significantly lower in likeability, trustworthiness, attractiveness, and femininity or masculinity
Association of Facial Paralysis With Perceptions of Personality and Physical Traits. Keon M. Parsa. JAMA Netw Open. 2020;3(6):e205495, June 24 2020, doi:10.1001/jamanetworkopen.2020.5495
Key Points
Question How is facial paralysis associated with the perception of attractiveness, femininity or masculinity, and personality, and do patient-reported outcome measures correlate with how patients are perceived by others?
Findings In this cross-sectional study including 20 patients with facial paralysis and 122 survey respondents, respondents rated photographs of patients with facial paralysis significantly lower in likeability, trustworthiness, attractiveness, and femininity or masculinity compared with the digitally edited images of patients without facial paralysis. Higher social function and total Facial Clinimetric Evaluation scores were associated with increased trustworthiness and attractiveness scores.
Meaning These results broaden understanding of how facial paralysis is associated with societal perceptions of persona.
Abstract
Importance Facial paralysis has a significant effect on affect display, with the most notable deficit being patients’ the inability to smile in the same way as those without paralysis. These impairments may result in undesirable judgements of personal qualities, thus leading to a significant social penalty in those who have the condition.
Objective To quantify the association of facial paralysis with the way smiling patients are perceived by others with respect to personality traits, attractiveness, and femininity or masculinity and to evaluate the potential association of facial palsy–related patient-reported outcome measures with how patients are perceived by others.
Design, Setting, and Participants This retrospective cross-sectional study used 20 images of smiling patients with facial paralysis evaluated between January 1, 2014, and December 31, 2016. Using photograph editing software, the photographs were edited to create a simulated nonparalysis smiling facial appearance. A total of 40 photographs were split into 4 groups of 10 photographs, each with 5 altered and 5 unaltered photographs. The surveys were designed such that altered and unaltered photographs of the same patient were not placed in the same survey to avoid recall bias. Anonymous raters used a 7-point Likert scale to rate their perception of each patient’s personality traits (ie, aggressiveness, likeability, and trustworthiness), attractiveness, and femininity or masculinity based on photographs in their assigned survey. Raters were blinded to study intent. Scores from the Facial Clinimetric Evaluation questionnaire were included to assess self-perception. Data were analyzed from November 11, 2019, to February 20, 2020.
Main Outcomes and Measures Ratings of personality traits, attractiveness, and femininity or masculinity. Social function domain scores and overall scores were analyzed from the Facial Clinimetric Evaluation questionnaire.
Results This study included photographs of 20 patients with facial paralysis (mean [range] age, 54 [28-69] years; 15 [75%] women). A total of 122 respondents completed the survey (71 [61%] women). Most respondents were between the ages of 25 and 34 years (79 participants [65%]). Overall, smiling photos of patients with facial paralysis were perceived as significantly less likeable (difference, −0.29; 95% CI, −0.43 to −0.14), trustworthy (difference, −0.25; 95% CI, −0.39 to −0.11), attractive (difference, −0.47; 95% CI, −0.62 to −0.32), and feminine or masculine (difference, −0.21; 95% CI, −0.38 to −0.03) compared with their simulated preparalysis photographs. When analyzed by sex, smiling women with facial paralysis experienced lower ratings for likeability (difference, −0.34; 95% CI, −0.53 to −0.16), trustworthiness (difference, −0.24; 95% CI, −0.43 to −0.06), attractiveness (difference, −0.74; 95% CI, −0.94 to −0.55), and femininity (difference, −0.35; 95% CI, −0.58 to −0.13). However, smiling men with facial paralysis only received significantly lower ratings for likeability (difference, −0.24; 95% CI, −0.47 to −0.01) and trustworthiness (difference, −0.30; 95% CI, −0.53 to −0.07). As patients’ self-reported social function and total Facial Clinimetric Evaluation scores increased, there was an increase in perceived trustworthiness (rs[480] = 0.11; P = .02) and attractiveness (rs[478] = 0.10; P = .04) scores by raters.
Conclusions and Relevance In this study, photographs of patients with facial paralysis received lower ratings for several personality and physical traits compared with digitally edited images with no facial paralysis. These findings suggest a social penalty associated with facial paralysis.

Discussion
The Duchenne smile is classically described as the anatomical marker of the genuine smile. The smile is distinctive, with the mouth turning up from the activation of the zygomatic major muscle, the cheeks lifting, and the appearance of wrinkles around the eyes (also known as crow’s feet) associated with simultaneous contraction of the orbicularis oculi. The absence of the Duchenne smile not only influences how people evaluate smiles but also how they are judged by others.29,30
The findings of this cross-sectional study suggest that the inability to effectively smile is associated with negative perceptions in likeability, trustworthiness, attractiveness, and femininity or masculinity for patients with facial paralysis. Paralysis affecting the mouth is among the most notable of facial asymmetries, such that palsies of the zygomatic and marginal branches of the facial nerve are considered to have a significantly greater need for correction.11,12 Interestingly, reanimation surgery of the lip significantly decreases the degree of attention to the mouth and can help decrease negative perceptions of patients with facial paralysis.31
A universal finding for our patient population was lower perceived trustworthiness for the photographs of patients with facial paralysis vs their digitally altered counterparts. Research in the psychological and social sciences corroborate these findings, such that a happy facial expression makes a person appear more trustworthy.31,32 Furthermore, having a facial appearance that conveys a positive emotional state enhances trust.33-35 These findings highlight the social significance of the asymmetric smile and the importance of further progress in the development of techniques to assist in mitigating the effects of facial paralysis.
It is interesting to find that men and women with facial paralysis did not experience the same social penalty with respect to their facial paralysis. The relative decrease in attractiveness and femininity perceived in women with facial paralysis likely reflects the different social expectations by sex in our society. This is consistent with the results reported in a 2019 study36 that suggest that the appearance of a smile is not as integral to the perception of masculinity as it is to femininity.
Lastly, there was a correlation between the way patients with facial paralysis perceived themselves and how they were perceived by others. Specifically, as self-perception of social function and overall facial function improved, there was an increase in perceived trustworthiness and attractiveness by others. This is similar to the results reported by Lyford-Pike et al37 that suggest that higher FaCE scores correspond with decreased perception of disfigurement by patients.
It is important to note that this study included patients with facial paralysis presenting with a range of facial impairment. Not all patients with facial paralysis experienced a significant decrease in the perception of their personality traits, femininity or masculinity, and attractiveness. More research is needed to better understand the different variables that can optimize outcomes at the individual patient level.
Limitations
There are several limitations to this study. This study was performed using static smiling images, but other studies have found that observers judged the severity of paralyzed faces to be more noticeable when viewing dynamic expressions.38 In addition, as this study included only patients willing to have their photos viewed by others, there may have been a selection bias rendering the study patient group to be less reflective of the true gamut of patients with facial paralysis.39
Twitter: While partisan opinion leaders are certainly polarized, centrist/non-political voices are much more likely to produce the most visible information; & there is little evidence of echo-chambers in consumption
Mukerjee, Subhayan, Kokil Jaidka, and Yphtach Lelkes. 2020. “The Ideological Landscape of Twitter: Comparing the Production Versus Consumption of Information on the Platform.” OSF Preprints. June 23. doi:10.31219/osf.io/w98ms
Abstract: There are mounting concerns that the information environment on Twitter is fragmented along ideological lines, with users ensconced into echo chambers with limited exposure to cross-cutting views. Previous studies have typically relied on small populations of political elites or opinion leaders to appraise this level of fragmentation. This study makes two main advancements over the existing body of literature. First, it identifies the need to make the distinction between information production and consumption. Second, it proposes weighted estimates of ideology, based on active use, to better assess the extent of polarization on the platform. Our analyses find little evidence that Twitter, at least in the United States, is polarized based on how information is produced by opinion leaders. While partisan opinion leaders are certainly polarized, centrist or non-political voices are much more likely to produce the most visible information on the platform. Analysis of co-exposure networks of how ordinary Americans follow these opinion leaders similarly reveals little evidence of echo-chambers in consumption. However, while the extent of ideological selective consumption is low, there does exist a small but dedicated audience for conservative opinion leaders on the platform.
