Delegating Decisions: Recruiting Others to Make Choices We Might Regret

Delegating Decisions: Recruiting Others to Make Choices We Might Regret. Mary Steffel and Elanor Williams. Journal of Consumer Research, ucx080. https://doi.org/10.1093/jcr/ucx080

Abstract: Consumers typically prefer freedom of choice, but when faced with a choice they might regret, they may prefer freedom from choice. Eight experiments show that people delegate difficult decisions, regardless of the decision's importance, and regardless of their potential surrogate's expertise. Delegation stems from a desire to avoid responsibility for potentially making the wrong choice rather than simply the desire to avoid the possibility of a poor outcome: although anticipated disappointment with the outcome and anticipated regret about one's decision both contribute to the decision to delegate, only anticipated regret directly leads people to delegate choices to others. Consequently, delegation is an appealing method for coping with difficult choices while allowing consumers to retain the benefits of choosing that they would forgo by opting out of the choice. Moreover, giving people the option to delegate makes them less prone to walk away from difficult choices empty-handed.

Poor Metacognitive Awareness of Belief Change

Poor Metacognitive Awareness of Belief Change. Michael Wolfe and Todd Williams. The Quarterly Journal of Experimental Psychology, https://doi.org/10.1080/17470218.2017.1363792

Abstract: When people change beliefs as a result of reading a text, are they aware of these changes? This question was examined for beliefs about spanking as an effective means of discipline. In two experiments, subjects reported beliefs about spanking effectiveness during a prescreening session. In a subsequent experimental session, subjects read a one-sided text that advocated a belief consistent or inconsistent position on the topic. After reading, subjects reported their current beliefs and attempted to recollect their initial beliefs. Subjects reading a belief inconsistent text were more likely to change their beliefs than those who read a belief consistent text. Recollections of initial beliefs tended to be biased in the direction of subjects' current beliefs. In addition, the relationship between the belief consistency of the text read and accuracy of belief recollections was mediated by belief change. This belief memory bias was independent of on-line text processing and comprehension measures, and indicates poor metacognitive awareness of belief change.

Intergenerational Consequences of a Geographic Mobility Shock

The Gift of Moving: Intergenerational Consequences of a Mobility Shock. Emi Nakamura, Jósef Sigurdsson, and Jón Steinsson. NBER Working Paper No. 22392. http://www.nber.org/papers/w22392

We exploit a volcanic “experiment" to study the costs and benefits of geographic mobility. We show that moving costs (broadly defined) are very large and labor therefore does not flow to locations where it earns the highest returns. In our experiment, a third of the houses in a town were covered by lava. People living in these houses where much more likely to move away permanently. For those younger than 25 years old who were induced to move, the “lava shock” dramatically raised lifetime earnings and education. Yet, the benefits of moving were very unequally distributed within the family: Those older than 25 (the parents) were made slightly worse off by the shock. The large gains from moving for the young are surprising in light of the fact that the town affected by our volcanic experiment was (and is) a relatively high income town. We interpret our findings as evidence of the importance of comparative advantage: the gains to moving may be very large for those badly matched to the location they happened to be born in, even if differences in average income are small.

Gossip as an Intrasexual Competition Strategy: Sex Differences in Gossip Frequency, Content, and Attitudes

Gossip as an Intrasexual Competition Strategy: Sex Differences in Gossip Frequency, Content, and Attitudes. Adam C. Davis. Evolutionary Psychological Science, https://link.springer.com/article/10.1007/s40806-017-0121-9

Abstract: From an evolutionary perspective, gossip has been considered a putative intrasexual competition strategy that is used to vie for mates and resources linked to reproductive success. To date, no study has directly examined the relations between intrasexual competitiveness, reported tendency to gossip, and attitudes toward gossiping. Limited empirical work has also focused on whether gossip frequency, gossip content, and gossip attitudes correspond to women’s and men’s divergent intrasexual competition strategies and evolved mating preferences. In a sample of 290 heterosexual young adults, we found that intrasexual competition positively predicted reported gossip frequency and favorable attitudes toward gossiping. Additionally, women reported a greater tendency to gossip in comparison to men, particularly about physical appearance and social information, whereas men reported gossiping more about achievement. Women also reported greater enjoyment of, and perceived more value in, gossiping than men. Collectively, these findings provide empirical support for the hypothesis that gossip is an intrasexual competition tactic that, by and large, corresponds to women’s and men’s evolved mate preferences and differential mate competition strategies.

The Wisdom in Virtue: Pursuit of Virtue Predicts Wise Reasoning About Personal Conflicts

The Wisdom in Virtue: Pursuit of Virtue Predicts Wise Reasoning About Personal Conflicts. Alex C. Huynh et al. Psychological Science, https://doi.org/10.1177/0956797617722621

Abstract: Most people can reason relatively wisely about others’ social conflicts, but often struggle to do so about their own (i.e., Solomon’s paradox). We suggest that true wisdom should involve the ability to reason wisely about both others’ and one’s own social conflicts, and we investigated the pursuit of virtue as a construct that predicts this broader capacity for wisdom. Results across two studies support prior findings regarding Solomon’s paradox: Participants (N = 623) more strongly endorsed wise-reasoning strategies (e.g., intellectual humility, adopting an outsider’s perspective) for resolving other people’s social conflicts than for resolving their own. The pursuit of virtue (e.g., pursuing personal ideals and contributing to other people) moderated this effect of conflict type. In both studies, greater endorsement of the pursuit of virtue was associated with greater endorsement of wise-reasoning strategies for one’s own personal conflicts; as a result, participants who highly endorsed the pursuit of virtue endorsed wise-reasoning strategies at similar levels for resolving their own social conflicts and resolving other people’s social conflicts. Implications of these results and underlying mechanisms are explored and discussed.

Brain Activity Unique to Orgasm in Women: An fMRI Analysis

Brain Activity Unique to Orgasm in Women: An fMRI Analysis. Nan J. Wise, Eleni Frangos, and Barry R. Komisaruk. The Journal of Sexual Medicine, https://doi.org/10.1016/j.jsxm.2017.08.014

Abstract

Background: Although the literature on imaging of regional brain activity during sexual arousal in women and men is extensive and largely consistent, that on orgasm is relatively limited and variable, owing in part to the methodologic challenges posed by variability in latency to orgasm in participants and head movement.

Aim: To compare brain activity at orgasm (self- and partner-induced) with that at the onset of genital stimulation, immediately before the onset of orgasm, and immediately after the cessation of orgasm and to upgrade the methodology for obtaining and analyzing functional magnetic resonance imaging (fMRI) findings.

Methods: Using fMRI, we sampled equivalent time points across female participants’ variable durations of stimulation and orgasm in response to self- and partner-induced clitoral stimulation. The first 20-second epoch of orgasm was contrasted with the 20-second epochs at the beginning of stimulation and immediately before and after orgasm. Separate analyses were conducted for whole-brain and brainstem regions of interest. For a finer-grained analysis of the peri-orgasm phase, we conducted a time-course analysis on regions of interest. Head movement was minimized to a mean less than 1.3 mm using a custom-fitted thermoplastic whole-head and neck brace stabilizer.

Outcomes: Ten women experienced orgasm elicited by self- and partner-induced genital stimulation in a Siemens 3-T Trio fMRI scanner.

Results: Brain activity gradually increased leading up to orgasm, peaked at orgasm, and then decreased. We found no evidence of deactivation of brain regions leading up to or during orgasm. The activated brain regions included sensory, motor, reward, frontal cortical, and brainstem regions (eg, nucleus accumbens, insula, anterior cingulate cortex, orbitofrontal cortex, operculum, right angular gyrus, paracentral lobule, cerebellum, hippocampus, amygdala, hypothalamus, ventral tegmental area, and dorsal raphe).

Clinical Translation: Insight gained from the present findings could provide guidance toward a rational basis for treatment of orgasmic disorders, including anorgasmia.

Strengths and Limitations: This is evidently the first fMRI study of orgasm elicited by self- and partner-induced genital stimulation in women. Methodologic solutions to the technical issues posed by excessive head movement and variable latencies to orgasm were successfully applied in the present study, enabling identification of brain regions involved in orgasm. Limitations include the small sample (N = 10), which combined self- and partner-induced stimulation datasets for analysis and which qualify the generalization of our conclusions.

Conclusion: Extensive cortical, subcortical, and brainstem regions reach peak levels of activity at orgasm.

Olfactory cues are more effective than visual cues in experimentally triggering autobiographical memories

Olfactory cues are more effective than visual cues in experimentally triggering autobiographical memories. Maaike J. de Bruijn & Michael Bender. Memory, http://dx.doi.org/10.1080/09658211.2017.1381744

Abstract: Folk wisdom often refers to odours as potent triggers for autobiographical memory, akin to the Proust phenomenon that describes Proust’s sudden recollection of a childhood memory when tasting a madeleine dipped into tea. Despite an increasing number of empirical studies on the effects of odours on cognition, conclusive evidence is still missing. We set out to examine the effectiveness of childhood and non-childhood odours as retrieval cues for autobiographical memories in a lab experiment. A total of 170 participants were presented with pilot-tested retrieval cues (either odours or images) to recall childhood memories and were then asked to rate the vividness, detail, and emotional intensity of these memories. Results showed that participants indeed reported richer memories when presented with childhood-related odours than childhood-related images or childhood-unrelated odours or images. An exploratory analysis of memory content with Linguistic Inquiry and Word Count did not reveal differences in affective content. The findings of this study support the notion that odours are particularly potent in eliciting rich memories and open up numerous avenues for further exploration.

Individuals who find food-related images more motivationally relevant than erotic ones may eat twice as much as their opposites

The reality of “food porn”: Larger brain responses to food-related cues than to erotic images predict cue-induced eating. Francesco Versace et al. BioRxiv.org,  September 5, 2017, https://doi.org/10.1101/184838

Abstract: While some individuals can defy the lure of temptation, many others find appetizing food irresistible. Using event-related potentials, we showed that individuals who find food-related images more motivationally relevant than erotic ones ("sign-trackers") are more susceptible to cue-induced eating and, in the presence of a palatable food option, eat twice as much as individuals with the opposite brain reactivity profile ("goal-trackers"). These findings contribute to the understanding of the neurobiological basis of vulnerability to cue-induced behaviors.

Perception of Causality: Categories and Constraints

Categories and Constraints in Causal Perception. Jonathan Kominsky et al. Psychological Science, last updated Sep 27 2017 https://osf.io/k8t4b/

Abstract: When object A moves adjacent to a stationary object, B, and in that instant A stops moving and B starts moving, people irresistibly see this as an event in which A causes B to move. Real-world causal collisions are subject to Newtonian constraints on the relative speed of B following the collision, but here we show that perceptual constraints on the relative speed of B (which align imprecisely with Newtonian principles) define two categories of causal events in perception. Using performance-based tasks, we show that triggering events, in which B moves noticeably faster than A, are treated as being categorically different from launching events, in which B does not move noticeably faster than A, and that these categories are unique to causal events (Experiments 1 and 2). Furthermore, we show that 7- to 9-month-old infants are sensitive to this distinction, which suggests that this boundary may be an early-developing component of causal perception (Experiment 3).

Acute exposure to blue wavelength light during memory consolidation improves verbal memory performance

Acute exposure to blue wavelength light during memory consolidation improves verbal memory performance. Anna Alkozei et al. PLoS One, September 2017, https://doi.org/10.1371/journal.pone.0184884

Abstract: Acute exposure to light within the blue wavelengths has been shown to enhance alertness and vigilance, and lead to improved speed on reaction time tasks, possibly due to activation of the noradrenergic system. It remains unclear, however, whether the effects of blue light extend beyond simple alertness processes to also enhance other aspects of cognition, such as memory performance. The aim of this study was to investigate the effects of a thirty minute pulse of blue light versus placebo (amber light) exposure in healthy normally rested individuals in the morning during verbal memory consolidation (i.e., 1.5 hours after memory acquisition) using an abbreviated version of the California Verbal Learning Test (CVLT-II). At delayed recall, individuals who received blue light (n = 12) during the consolidation period showed significantly better long-delay verbal recall than individuals who received amber light exposure (n = 18), while controlling for the effects of general intelligence, depressive symptoms and habitual wake time. These findings extend previous work demonstrating the effect of blue light on brain activation and alertness to further demonstrate its effectiveness at facilitating better memory consolidation and subsequent retention of verbal material. Although preliminary, these findings point to a potential application of blue wavelength light to optimize memory performance in healthy populations. It remains to be determined whether blue light exposure may also enhance performance in clinical populations with memory deficits.

Changing beliefs about past public events with believable and overtly unbelievable doctored photographs

Changing beliefs about past public events with believable and unbelievable doctored photographs. Robert Nash. Memory, http://dx.doi.org/10.1080/09658211.2017.1364393

Abstract: Doctored photographs can shape what people believe and remember about prominent public events, perhaps due to their apparent credibility. In three studies, subjects completed surveys about the 2012 London Olympic torch relay (Experiment 1) or the 2011 Royal Wedding of Prince William and Kate Middleton (Experiments 2-3). Some were shown a genuine photo of the event; others saw a doctored photo that depicted protesters and unrest. A third group of subjects saw a doctored photo whose inauthenticity had been made explicit, either by adding a written disclaimer (Experiment 1) or by making the digital manipulation deliberately poor (Experiments 2-3). In all three studies, doctored photos had small effects on a subset of subjects' beliefs about the events. Of central interest though, comparable effects also emerged when the photos were overtly inauthentic. These findings suggest that cognitive mechanisms other than credibility - such as familiarity misattribution and mental imagery - can rapidly influence beliefs about past events even when the low credibility of a source is overt.

Preliminary Evidence For Existence of Oral Sex in a Rural Igbo Community in Southeast Nigeria

Preliminary Evidence For Existence of Oral Sex in a Rural Igbo Community in Southeast Nigeria. Pavol Prokop, Ike E. Onyishi, Chiedozie O. Okafor & Michael N. Pham. Human Ethology Bulletin, Volume 32, No 3, 129-140,  https://doi.org/10.22330/heb/323/129-140

ABSTRACT: There is debate regarding whether oral sex recurred over human evolution. We investigated the occurrence of oral sex (cunnilingus and fellatio) and other sexual activities among a rural Igbo community in south-east Nigeria. We found that giving and receiving oral sex was less common relative to other sexual activities in both men and women. Both sexes reported more frequent vaginal sexual intercourse (particularly ventro-ventral posture compared with dorso-ventral posture) in the past 10 days compared to oral sex. Taken together, our data suggests that vaginal sexual activities follow similar patterns that are documented in other parts of world and that oral sex occurred less frequently in this traditional society.

Women's Attraction to Benevolent Sexism: Needing Relationship Security Predicts Greater Attraction to Men who Endorse Benevolent Sexism

Women's Attraction to Benevolent Sexism: Needing Relationship Security Predicts Greater Attraction to Men who Endorse Benevolent Sexism. Emily Cross and Nickola Overall. European Journal of Social Psychology, doi: 10.1002/ejsp.2334.

Abstract: Benevolent sexism prescribes that men should cherish and protect women in intimate relationships. Despite the romantic tone of these attitudes, prior research indicates that benevolent sexism undermines women's competence, ambition and independence. Ambivalent sexism theory proposes that benevolent sexism is able to incur these costs because the promise of a chivalrous protective partner offers women security in their intimate relationships. We tested this key proposition by examining whether women who intensely need relationship security — women higher in attachment anxiety — are more attracted to men who endorse benevolent sexism. Highly anxious women (N = 632) rated men described as endorsing benevolent sexism as relatively more attractive, and reported greater preferences for partners to hold benevolently sexist attitudes. These results advance understanding regarding the underlying reasons women find benevolent sexism appealing and identify who will be most vulnerable to the potential costs of benevolent sexism.
