There has long been skepticism among both scientists and laypersons that male bisexual orientation exists; paper finds robust evidence that male sexual orientation is expressed on a continuum

Robust evidence for bisexual orientation among men. Jeremy Jabboura et al. Proceedings of the National Academy of Sciences, Jun 2020. https://www.pnas.org/content/pnas/early/2020/07/14/2003631117.full.pdf

Significance: There has long been skepticism among both scientists and laypersons that male bisexual orientation exists. Skeptics have claimed that men who self-identify as bisexual are actually homosexual or heterosexual. (The existence of female bisexuality has been less controversial.) This controversy can be resolved using objective, genital responses of men to male and female erotic stimuli. We combined nearly all available data (from eight previous American, British, and Canadian studies) to form a dataset of more than 500 men, much larger than any previous individual study, and conducted rigorous statistical tests. Results provided compelling evidence that bisexualidentified men tend to show bisexual genital and subjective arousal patterns. Male sexual orientation is expressed on a continuum rather than dichotomously.

Abstract: The question whether some men have a bisexual orientation—that is, whether they are substantially sexually aroused and attracted to both sexes—has remained controversial among both scientists and laypersons. Skeptics believe that male sexual orientation can only be homosexual or heterosexual, and that bisexual identification reflects nonsexual concerns, such as a desire to deemphasize homosexuality. Although most bisexual-identified men report that they are attracted to both men and women, self-report data cannot refute these claims. Patterns of physiological (genital) arousal to male and female erotic stimuli can provide compelling evidence for male sexual orientation. (In contrast, most women provide similar physiological responses to male and female stimuli.) We investigated whether men who self-report bisexual feelings tend to produce bisexual arousal patterns. Prior studies of this issue have been small, used potentially invalid statistical tests, and produced inconsistent findings. We combined nearly all previously published data (from eight previous studies in the United States, United Kingdom, and Canada), yielding a sample of 474 to 588 men (depending on analysis). All participants were cisgender males. Highly robust results showed that bisexual-identified men’s genital and subjective arousal patterns were more bisexual than were those who identified as exclusively heterosexual or homosexual. These findings support the view that male sexual orientation contains a range, from heterosexuality, to bisexuality, to homosexuality.

From 2019... Foundational assumptions of the "random effects" model used pervasively in psychology impose far stronger constraints on the generalizability of results than most researchers appreciate

From 2019... Yarkoni, Tal. 2019. “The Generalizability Crisis.” PsyArXiv. November 22. doi:10.31234/osf.io/jqw35

Abstract: Most theories and hypotheses in psychology are verbal in nature, yet their evaluation overwhelmingly relies on inferential statistical procedures. The validity of the move from qualitative to quantitative analysis depends on the verbal and statistical expressions of a hypothesis being closely aligned—that is, that the two must refer to roughly the same set of hypothetical observations. Here I argue that most inferential statistical tests in psychology fail to meet this basic condition. I demonstrate how foundational assumptions of the "random effects" model used pervasively in psychology impose far stronger constraints on the generalizability of results than most researchers appreciate. Ignoring these constraints dramatically inflates false positive rates and routinely leads researchers to draw sweeping verbal generalizations that lack any meaningful connection to the statistical quantities they are putatively based on. I argue that the routine failure to consider the generalizability of one's conclusions from a statistical perspective lies at the root of many of psychology's ongoing problems (e.g., the replication crisis), and conclude with a discussion of several potential avenues for improvement.



School bullying victimization was far less frequently recalled by the Chinese sample (6.2%–12.6%) than the German sample (29.3%–37.0%); bullies in China had poor mental health comparable to victims

Bullies Get Away With It, But Not Everywhere: Mental Health Sequelae of Bullying in Chinese and German Students. Muyu Lin et al. Journal of Cross-Cultural Psychology, August 17, 2020. https://doi.org/10.1177/0022022120949913

Abstract: Bullying victimization is associated with adverse mental health consequences, while bullies suffer few or no adverse consequences in Western societies. Yet the universality of these consequences across western and eastern cultures is unknown. The current study investigated retrospective bullying experience in primary and secondary schools and its effects on adult mental health (depression, anxiety, stress, lifetime suicidal behavior, positive mental health, life satisfaction, social support, self-efficacy, and sense of control) in 5,012 Chinese and 1,935 German university students. School bullying victimization was far less frequently recalled by the Chinese sample (6.2%–12.6%) than the German sample (29.3%–37.0%), but victims had similar adverse mental health in both countries. In Germany, bullies and not-involved had equally good mental health, whereas bullies in China had poor mental health comparable to victims. Bullying victimization has similar adverse effects on mental health across countries. However, compared to the German students, the prevalence of school bullying is significantly lower, and bullies are also more likely to suffer mental health problems in adulthood in Chinese students. The differences of reasons for and consequences of being bullies are discussed and may have important implications for evolutionary theories and interventions of bullying.

Bisexual people had up to six times the odds of engaging in Non-Suicidal Self-Injury compared to other sexualities. Mental health variables of anxiety and depression symptoms were found to be most common

Bisexuality and Non-Suicidal Self-Injury (NSSI): A narrative synthesis of associated variables and a meta-analysis of risk. Brendan J. Dunlop et al. Journal of Affective Disorders, Volume 276, November 1 2020, Pages 1159-1172. https://doi.org/10.1016/j.jad.2020.07.103

Highlights
• Bisexual people have heightened odds of engaging in Non-Suicidal Self-Injury.
• A narrative synthesis finds anxiety and depression associated most for this group.
• Studies frequently did not report bisexual people separately from others.
• Risk of bias in included studies was most commonly found to be moderate.

Abstract
Background
Bisexual people have been found to be at increased risk of non-suicidal self-injury (NSSI) when compared to heterosexual and gay or lesbian people. The purpose of this review was to update the estimated risk of NSSI for bisexual people and to examine variables that have been associated with NSSI in this population.

Methods: The protocol for this paper was pre-registered (CRD42019145299). An electronic search of PsycINFO, CINAHL Plus, PubMed, Ovid Online and Web of Science was undertaken from earliest available date to October 2019. Twenty-four eligible papers were identified. Meta-analyses, including moderator analysis, were conducted to ascertain NSSI risk and a narrative synthesis was undertaken of predictors and correlates. All studies were assessed for risk of bias.

Results: Bisexual people had up to six times the odds of engaging in NSSI compared to other sexualities. Mental health variables of anxiety and depression symptoms were found to be most commonly associated with NSSI for this population. The majority of studies had moderate risk of bias. This review demonstrates that bisexual people have an elevated risk of engaging in NSSI. Increased incidence of anxiety and depression and exposure to negative life events may explain this increased risk.

Limitations: Studies were found to be consistently cross-sectional in design and limited to western cultures. A limitation of this review was that only English language papers were included.

Conclusions: Results are clinically relevant as they suggest early identification and prevention of NSSI can be achieved. Future research should examine bisexual people independently of others.

Cross-country study: Mothers were predominantly more authoritative than fathers, and fathers were mostly more authoritarian than mothers (based on both parent and descendant reports)

Systematic review of the differences between mothers and fathers in parenting styles and practices. Yosi Yaffe. Current Psychology (2020). Aug 23 2020. https://link.springer.com/article/10.1007/s12144-020-01014-6

Abstract: Parenting is a broad construct that comprises stable and durable attitudes and behaviors regarding child-rearing. Since mothers and fathers play different roles in the family, parenting styles and practices in childhood and adolescence may differ depending on the parents’ and adolescents’ gender. While gender differences in parenting are theoretically warranted, the research literature in this field is considerably limited and lacking conclusive information dealing with this question. Therefore, the aim of this systematic review is to aggregate and synthesize the available research studies containing significant findings on the differences between mothers and fathers in parenting styles and practices. For that purpose, we conducted a systematic search of the PsycInfo, Scopus, Eric, and Web of Science databases, covering literature published from 1990 to 2020. The search was restricted to peer-reviewed studies in English alone. Our findings reveal that mothers as compared to fathers are perceived as more accepting, responsive, and supportive, as well as more behaviorally controlling, demanding, and autonomy granting than fathers. Accordingly, in the studies comparing parents on the constructs of overall parenting styles, mothers were predominantly more authoritative than fathers, and fathers were mostly more authoritarian than mothers (based on both parent and descendant reports). These parental differences established by research from over 15 countries around the globe seem to apply similarly for male and female descendants, while principally not varying by their age.

Callousness, but not pornography use, significantly predicted self-reported sexual aggressiveness; more frequent pornography use was related to lower odds of reporting sexual aggressiveness

Is Male Adolescents’ Sexual Aggressiveness Better Explained by Prior Pornography Use or Callousness? A Brief Report. Aleksandar Štulhofer. Sexual Abuse, August 26, 2020. https://doi.org/10.1177/1079063220952777

Abstract: To address growing concerns about the role of pornography use in adolescents’ sexual socialization, we explored the role of callousness, relative to pornography use, in male adolescents’ self-reported sexual aggressiveness. Two competing conceptualizations of this role were tested using data from a larger longitudinal research project on sexualized media use and adolescent well-being. Considering that callousness was assessed at only two waves (T2 and T4), 381 male Croatian adolescents (Mage = 15.88, SD = 0.49) who participated in both waves were included in the study. Generalized mixed effects regression modeling indicated that callousness, but not pornography use, significantly predicted sexual aggressiveness 11 months later. Callousness also moderated the association between pornography use and sexual aggressiveness, so that among participants who scored high in callousness, more frequent pornography use was related to lower odds of reporting sexual aggressiveness. High callousness is a risk factor for male adolescents’ sexual aggression and should be addressed in prevention programs.

Toxoplasma gondii is reported to manipulate the behavior of its non-definitive hosts in ways that promote lethal interactions with the parasite's definitive feline hosts; infected hyenas have less fear of lions

Toxoplasma gondii infections are associated with boldness towards lions in wild hyena hosts. Eben Gering,  View ORCID ProfileZachary M. Laubach, Patricia Weber, Gisela Soboll Hussey, Kenna D. S. Lehmann, Tracy M. Montgomery, Julie W. Turner, Wei Perng, Malit O. Pioon, Kay E. Holekamp, Thomas Getty. bioRxiv Aug27 2020. https://doi.org/10.1101/2020.08.26.268805

Abstract: Toxoplasma gondii is widely reported to manipulate the behavior of its non-definitive hosts in ways that promote lethal interactions with the parasite's definitive feline hosts. Nonetheless, there is a lack of data on the association between T. gondii infection and costly behavioral interactions with felids in nature. Here, we report that three decades of field observations reveal T. gondii infected hyena cubs approach lions more closely than uninfected peers and have higher rates of lion mortality. Our findings support the hypothesis that T. gondii's manipulation of host boldness is an extended phenotype that promotes parasite transmission from intermediate hosts to feline predators. While upregulating hyena boldness toward lions might achieve this, it may also reflect a collateral influence of manipulative traits that evolved in other hosts (e.g., rodents). In either case, our findings corroborate the potential impacts of a globally distributed and generalist parasite (T. gondii) on fitness-related interaction with felids in a wild host.


COVID-19 lockdown policies & imprisonment: Psychological parallels can be drawn between the two forms of confinement, & ordinary citizens in lockdown have, to some extent, sensed the ‘pains of imprisonment’

Dhami, Mandeep K., Leonardo Weiss-Cohen, and Peter Ayton. 2020. “Are People Experiencing the ‘pains of Imprisonment’ During the Covid-19 Lockdown?.” PsyArXiv. August 27. doi:10.31234/osf.io/5xwbs

Abstract
Background: By the end of March 2020, more than a fifth of the world’s population was in various degrees of ‘lockdown’ in order to slow the spread of Covid-19. This enforced confinement led some to liken lockdown to imprisonment. We directly compared individual’s experiences of lockdown with prisoners’ experiences of imprisonment in order to determine whether psychological parallels can be drawn between these two forms of confinement.
Method: Online surveys of adults in lockdown in the UK (N = 300) and California (N = 450) were conducted four and five weeks into lockdown in each region, respectively. The UK data was then compared to Souza and Dhami’s (2010) sample of 267 medium security prisoners in England, and the Californian data was compared to Dhami et al.’s (2007) sample of 307 medium security Federal prisoners in California. We measured the effects of Group (Lockdown v. Prison) on five categories of dependent variables (i.e., activity, social contact, thoughts, feelings, and rule-breaking), controlling for demographic differences between the groups.
Results: In both regions, people in lockdown thought significantly less often about missing their freedom, as well as missing their family and friends living elsewhere than did first-time prisoners. However, people in lockdown in both regions were also significantly less engaged in a range of daily activities than were first-time prisoners. Additionally, in both regions, people in lockdown reported feeling more hopeless than first-time prisoners.
Conclusions: Although Governments introducing lockdown policies do not intend to punish their citizens as courts do when sending convicted offenders to prison, such policies can have unintended adverse consequences. Psychological parallels can be drawn between the two forms of confinement, and ordinary citizens in lockdown have, to some extent, sensed the ‘pains of imprisonment.’

Non-Hispanic White Americans generally conceptualize multicultural policies in nonzero-sum terms; even so, sometimes diversity efforts are likely to elicit backlash from majority group members

Understanding Whites’ perceptions of multicultural policies: A (non)zero-sum framework? Taylor Ballinger & Jennifer Crocker. Journal of Personality and Social Psychology, Jul 30 2020. https://doi.org/10.1037/pspi0000315

Abstract: Non-Hispanic Whites can perceive multicultural diversity policies as excluding their group and threatening their identity. However, increasing demographic diversity and the proliferation of organizational diversity efforts may have led Whites to view multicultural policies in more nonzero-sum ways. Reanalyzing nationally representative data, Study 1 showed that over the past 10 years, White Americans have become more supportive of diversity policies that explicitly recognize group memberships and have become less likely to view these policies as harmful to their group. Five experiments further showed that a multicultural (vs. colorblind) policy did not increase Whites’ experiences of social identity threat (Studies 2–6) or their perceived exclusion from a company’s diversity efforts (Studies 4–6). While a multicultural policy increased how much Whites believed an organization generally valued diversity and specifically valued the group differences of racial minorities, it did not decrease how much Whites believed their own group differences were valued (Studies 4–5). A multicultural policy only threatened Whites when group differences were narrowly defined to exclude their group (Study 6). An internal meta-analysis (N = 1,998) supported these conclusions and found they did not depend on need to belong, ethnic identification, political ideology, or the imagined presence of an outgroup coworker. These findings indicate that non-Hispanic White Americans generally conceptualize multicultural policies in nonzero-sum terms and suggest that (non)zero-sum beliefs may be key to understanding when diversity efforts are likely to elicit backlash from majority group members.


These results do not support the use of probiotic, prebiotic, and fermented food interventions for cognitive performance

Prebiotics, probiotics, fermented foods and cognitive outcomes: A meta-analysis of randomized controlled trials. Wolfgang Marx et al. Neuroscience & Biobehavioral Reviews, August 27 2020. https://doi.org/10.1016/j.neubiorev.2020.07.036

Highlights
• Twenty-two studies investigated pre- and probiotics and fermented foods on cognition.
• No intervention had a significant effect on global or specific domains of cognition.
• Heterogeneity regarding the population, cognitive tests, and intervention identified.

Abstract: This systematic review and meta-analysis aimed to evaluate randomized controlled trials that investigated the use of probiotic, prebiotic, and fermented food interventions for cognitive performance. In total, 22 studies (n = 1551) were included that investigated probiotics (11 studies, n = 724), prebiotics (5 studies, n = 355), and fermented foods (6 studies, n = 472). Despite several individual studies (14 of 22) reporting significant improvements in specific cognitive domains, results of the pooled meta-analysis found no significant effect for any intervention for global cognition (Probiotics: g = 0.115, 95 %CI -0.041, 0.270, p = 0.148; Prebiotics: g = 0.077, 95 %CI -0.091, 0.246, p = 0.369; Fermented food: g = 0.164 95 %CI -0.017, 0.345, p = 0.076) or any individual cognitive domain. Most studies (16 of 22) had low risk of bias. These results do not support the use of probiotic, prebiotic, and fermented food interventions for cognitive outcomes. This may be due to the limited number of small and short-term studies as well clinical heterogeneity relating to the population, cognitive tests, and intervention. Therefore, further trials that investigate these interventions in clinical populations using adequately powered samples are warranted.

Contrary to the generally accepted beliefs that wearing eyeglasses makes you look older & wearing sunglasses make you look younger, our results suggest that the effect of glasses on age perception is rather small

Do Glasses Modulate Age Perception? Nicolas M. Brunet, Jonathan Sharp. i-Perception, August 26, 2020. https://doi.org/10.1177/2041669520953457

Abstract: No formal studies have reported how glasses influence age perception, except for a London Vision Clinic survey that found that people over 45 look 5 or more years older when wearing eyeglasses. To investigate the effect of eyeglasses and sunglasses on age perception while controlling for age and interpersonal differences, we digitally manipulated the photographs of faces of 50 young adults, to create two age conditions (young and old) and three eyewear conditions (no glasses, eyeglasses, and sunglasses). Participants then estimated the age of the faces, displayed in random order. Contrary to the generally accepted beliefs that wearing eyeglasses makes you look older and wearing sunglasses make you look younger, our results suggest that the effect of glasses on age perception is rather small.

The posture adopted during a task can improve cognitive performance with a better answer for arithmetic in the sitting position than during walking but more correctly recalled words while walking

Is it better to sit down, stand up or walk when performing memory and arithmetic activities? G. Abou Khalil, K. Doré-Mazars, P. Senot, D. P. Wang & A. Legrand. Experimental Brain Research (2020). Aug 26. https://rd.springer.com/article/10.1007/s00221-020-05858-z

Abstract: It is now accepted that performing a cognitive task impacts postural control (Polskaia and Lajoie 2016; Vuillerme et al. Neurosci Lett 291: 77–80, 2000). However, the reverse impact of posture on cognitive performance is less documented. The present study investigated performance in two cognitive activities (memory and arithmetic) performed in three different postural conditions (sitting, standing, and walking). Overall, our data suggest that the posture adopted during a task can improve cognitive performance with a better answer for arithmetic in the sitting position than during walking but more correctly recalled words while walking. This study, thus, suggests that there could be preferential association between cognition and posture, i.e., memory cognitive performance can be improved when walking and mental arithmetic while sitting.


An interquartile increase in local individualism offsets 41% of the effect of state lockdown orders on social distancing and reduces COVID-related charitable fundraising by 48%

Abstract: Collective actions and government interventions are important measures to alleviate the negative impact of the COVID-19 pandemic. However, engagement in these actions and compliance to government policies vary significantly within the U.S. This study explains this heterogeneity through an understudied cultural dimension—individualism. Using novel big data analytics on a quarter petabyte of data, we present the first evidence on how individualism affects offline social distancing and online charitable crowdfunding around state-issued stay-at-home orders. Following economic history studies, we leverage GIS techniques to construct a U.S. county-level measure of individualism that traces the amounts of time counties spent at the frontier during the 1790-1890 period. We then use high-dimensional fixed-effect models, text mining, geo-analytics, and a novel migration-based identification strategy to analyze social distancing compliance and GoFundMe fundraising activities. Our analysis reveals that an interquartile increase in local individualism offsets 41% of the effect of state lockdown orders on social distancing and reduces COVID-related charitable fundraising by 48%. These effects are stronger in counties where social distancing generates larger externalities, suggesting our results are partly driven by individualism lowering the tendency to internalize the externality of their actions. Finally, we show that government interventions, such as stimulus checks, can mitigate the negative impact of individualism. Our study is the first to identify the downside of individualism during crises. It also demonstrates the importance of big data-driven, culture-aware policymaking.

Blind spots in self-perceptions: Because individuals and others differ in their susceptibility to biases or motivations and in the information they have access to, self- and other-knowledge will vary by trait

Self–Other Knowledge Asymmetry (SOKA) Model. Kathryn L. Bollich-Ziegler. In The Oxford Handbook of Accurate Personality Judgment (edited by Tera D. Letzring and Jana S. Spain). Jul 2020, DOI 10.1093/oxfordhb/9780190912529.013.10

Abstract: Despite the strong intuition that people know themselves well, much research in self-perception demonstrates the biases present when evaluating one’s own personality traits. What specifically are these blind spots in self-perceptions? Are self-perceptions always disconnected from reality? And under what circumstances might other people actually be more accurate about the self? The self–other knowledge asymmetry (SOKA) model suggests that because individuals and others differ in their susceptibility to biases or motivations and in the information they have access to, self- and other-knowledge will vary by trait. The present chapter outlines when and why other-perceptions are sometimes more accurate than self-perceptions, as well as when self-reports can be most trusted. Also discussed are next steps in the study of self- and other-knowledge, including practical, methodological, and interdisciplinary considerations and extensions. In sum, this chapter illustrates the importance of taking multiple perspectives in order to accurately understand a person.

Brain region becomes active in people born blind when they touch a 3D model of a face with their hands, suggesting that this area does not require visual experience to develop a preference for faces

Visual experience is not necessary for the development of face-selectivity in the lateral fusiform gyrus. N. Apurva Ratan Murty, Santani Teng, David Beeler, Anna Mynick, Aude Oliva, and Nancy Kanwisher. Proceedings of the National Academy of Sciences, August 24, 2020. https://doi.org/10.1073/pnas.2004607117

Significance: Here we show robust face-selectivity in the lateral fusiform gyrus of congenitally blind participants during haptic exploration of 3D-printed stimuli, indicating that neither visual experience, nor fovea-biased input, nor visual expertise is necessary for face-selectivity to arise in its characteristic location. Similar resting fMRI correlation fingerprints in individual blind and sighted participants suggest a role for long-range connectivity in the specification of the cortical locus of face-selectivity.

Abstract: The fusiform face area responds selectively to faces and is causally involved in face perception. How does face-selectivity in the fusiform arise in development, and why does it develop so systematically in the same location across individuals? Preferential cortical responses to faces develop early in infancy, yet evidence is conflicting on the central question of whether visual experience with faces is necessary. Here, we revisit this question by scanning congenitally blind individuals with fMRI while they haptically explored 3D-printed faces and other stimuli. We found robust face-selective responses in the lateral fusiform gyrus of individual blind participants during haptic exploration of stimuli, indicating that neither visual experience with faces nor fovea-biased inputs is necessary for face-selectivity to arise in the lateral fusiform gyrus. Our results instead suggest a role for long-range connectivity in specifying the location of face-selectivity in the human brain.

Popular version: Face-specific brain area responds to faces even in people born blind - Study finds that the fusiform face area is active when blind people touch 3D models of faces. Anne Trafton. MIT News Office, August 26, 2020. https://news.mit.edu/2020/fusiform-brain-faces-blind-0826
More than 20 years ago, neuroscientist Nancy Kanwisher and others discovered that a small section of the brain located near the base of the skull responds much more strongly to faces than to other objects we see. This area, known as the fusiform face area, is believed to be specialized for identifying faces. 
Now, in a surprising new finding, Kanwisher and her colleagues have shown that this same region also becomes active in people who have been blind since birth, when they touch a three-dimensional model of a face with their hands. The finding suggests that this area does not require visual experience to develop a preference for faces. 
“That doesn’t mean that visual input doesn’t play a role in sighted subjects — it probably does,” she says. “What we showed here is that visual input is not necessary to develop this particular patch, in the same location, with the same selectivity for faces. That was pretty astonishing.”

Seeing what you want to see: Sexual activation makes potential partners seem more appealing and romantically interested

Seeing what you want to see: Sexual activation makes potential partners seem more appealing and romantically interested. Gurit E. Birnbaum et al. Journal of Social and Personal Relationships, August 26, 2020. https://doi.org/10.1177/0265407520952162

Abstract: Recent studies have indicated that activation of the sexual system fosters relationship initiation. In three studies, we expand on this work to investigate whether sexual activation encourages initiating relationship with prospective partners by biasing the way they are perceived. In all studies, participants encountered a potential partner and rated this partner’s attractiveness and romantic interest following sexual activation. Participants’ interest in the partner was self-reported or evaluated by raters. Study 1 revealed that sexual activation led participants to perceive potential partners as more attractive and interested in oneself. Study 2 added to these findings, providing a test of sexual priming rather than more general closeness priming. Mediational analyses in Study 3 indicated that heightened romantic interest mediated the link between sexual activation and perceiving potential partners as more interested in oneself. These findings suggest that sexual activation facilitates relationship initiation by motivating projection of one’s desires onto prospective partners.

Forgoing earned incentives to signal pure motives: Financial incentives have self-image costs, those who receive incentives view their actions less positively due to the perceived incompatibility between incentives & intrinsic motives

Forgoing earned incentives to signal pure motives. Erika Kirgios et al. Proceedings of the National Academy of Sciences, July 21 2020, Pages 16891-16897. https://www.pnas.org/content/117/29/16891

Abstract: Policy makers, employers, and insurers often provide financial incentives to encourage citizens, employees, and customers to take actions that are good for them or for society (e.g., energy conservation, healthy living, safe driving). Although financial incentives are often effective at inducing good behavior, they’ve been shown to have self-image costs: Those who receive incentives view their actions less positively due to the perceived incompatibility between financial incentives and intrinsic motives. We test an intervention that allows organizations and individuals to resolve this tension: We use financial rewards to kick-start good behavior and then offer individuals the opportunity to give up some or all of their earned financial rewards in order to boost their self-image. Two preregistered studies -- an incentivized online experiment (n = 763) on prosocial behavior and a large field experiment (n = 17,968) on exercise -- provide evidence that emphasizing the intrinsic rewards of a past action leads individuals to forgo or donate earned financial rewards. Our intervention allows individuals to retroactively signal that they acted for the right reason, which we call “motivation laundering.” We discuss the implications of motivation laundering for the design of incentive systems and behavioral change.


Moral contagion effects may be explained more by self-presentation (observers infer immorality by association) than by physical contamination

Reputation management as an alternative explanation for the “contagiousness” of immorality. Tom Kupfer & Roger Giner-Sorolla. Evolution and Human Behavior, Aug 20 2020. https://doi.org/10.1016/j.evolhumbehav.2020.08.005

Abstract: Previous findings showing that people are reluctant to contact morally disgusting objects such as Nazi clothing have been interpreted as showing that immorality is perceived as physically contaminating. However, self-presentation concerns could underlie the apparent contagiousness of immorality: associating visibly with immoral stimuli risks reputation damage because observers infer immorality by association. In a scenario, participants preferred to wear a Nazi armband under rather than over their clothing, despite the under choice requiring skin contact (Study 1). And participants reported being primarily motivated by reputation, not contamination. Studies 1a and 1b revealed that, when public display was kept constant to minimize reputation concerns, skin contact increased discomfort by a small amount. A lab study using a real Nazi armband showed that the preference for hiding the armband was stronger with an audience (Study 2). Changing perspective in Study 3, third parties judged targets who made direct contact with the armband as less immoral, and even less contaminated, than those who displayed the armband. Another scenario in Study 4 revealed a strong effect of public display, but no effect of skin contact, on negative feelings about wearing an immoral t-shirt. Overall, findings suggest that apparent moral contagion effects may be explained more by self-presentation than by contamination.



Having photos of close others in sight decreases the hegemony of an economic schema in people’s minds, which in turn decreases their propensity to commit unethical behavior

Show me the ... family: How photos of meaningful relationships reduce unethical behavior at work. Ashley Hardin, Christopher Bauman & David Mayer. Organizational Behavior and Human Decision Processes, November 2020, Pages 93-108. https://www.sciencedirect.com/science/article/abs/pii/S0749597820303629

Abstract: Environmental cues in the workplace influence unethical behavior, but the effects of these cues are less well understood than the effects of individual differences and social aspects of situations on unethical behavior. In this paper, we examine a common but underappreciated aspect of workspaces: photos of close others. Drawing on the literatures on symbols at work and behavioral ethics, we theorize that having photos of close others in sight decreases the hegemony of an economic schema in people’s minds, which in turn decreases their propensity to commit unethical behavior. Supporting our theory, a field survey and three experiments find a negative relationship between displaying photos of close others at work and financial transgressions and indicate that a decrease in the salience of the economic schema is a mechanism that drives the effect. We discuss implications of the results for the literatures on behavioral ethics, symbols at work, and work-life integration.

Consumers' schadenfreude over another's unrelated bad purchase as positive information about their own choices; & through such misattribution become more satisfied with their own choices

So happy for your loss: Consumer schadenfreude increases choice satisfaction. Dmytro Moisieiev  Radu Dimitriu  Shailendra P. Jain. Psychology & Marketing, August 25 2020 https://doi.org/10.1002/mar.21399

Abstract: Consumers often feel schadenfreude, an emotion reflecting an experience of pleasure over misfortunes of another. Schadenfreude has found wide use in advertising, but its actual consequences for consumers have not been thoroughly documented. The present research investigates the effect of schadenfreude on consumers' satisfaction with choices they have made. Building on the feelings‐as‐information theory, the authors posit that consumers take their positive feelings of schadenfreude over another's unrelated bad purchase as positive information about their own choices, and through such misattribution become more satisfied with their own choices. Three experiments show that feeling schadenfreude over another consumer's bad purchase makes consumers more satisfied with their own choices (Study 1), regardless of whether the other's bad purchase is in the same or in a different product category as one's own choice (Study 2), but only so long as consumers are not aware that they are engaging in misattribution (Study 3). The present research contributes to the literature on schadenfreude and feelings‐as‐information theory. Its findings may be used by marketers aiming to exert an unconscious influence on consumer satisfaction.


6 GENERAL DISCUSSION

6.1 Theoretical contributions

Social norms often demand a sympathetic response to another's misfortune. Schadenfreude however runs counter to this expectation, being a feeling of pleasure over another's misfortune. In that sense, it is a peculiar and complex emotion and some may even view it as socially reprehensible (Kramer et al., 2011).
At an abstract level, our research contributes to the literature on the consequences of complex emotions (Kramer, Lau‐Gesk, & Chiu, 2009; Williams & Aaker, 2002). More specifically, it extends the emerging scholarship on some of the outcomes of consumer schadenfreude (Kramer et al., 2011; Loebnitz & Grunert, 2019; Yucel‐Aybat & Kramer, 2017). Informed by the feelings‐as‐information theory (Schwarz, 2012; Schwarz & Clore, 2007), the current work reveals a surprising finding across three empirical studies—that witnessing another's failed purchase can make consumers feel better about their own choice, even though another's failure should rationally not impact the evaluation of one's own choice. Although consumers should be expected to recognize the source of their positive feelings (i.e., another's failure) and separate it from unrelated judgments, they seem to not be very adept at doing so.
Kramer et al. (2011) show that schadenfreude felt before a choice makes consumers more conservative in their choice. We show that after making a choice, schadenfreude might actually make consumers less conservative in evaluating their choice. These findings in aggregate may not be as contrasting as they appear. Kramer et al. (2011) examined the effect of schadenfreude before making a choice while we investigate its effect after making a choice. The dependent variables in the studies are also different: Kramer et al. (2011) are interested in risky versus safe choices while we are interested in choice satisfaction. In aggregate, these two inquiries enrich our understanding of the consequences of schadenfreude before and after choice by looking at different outcome variables.
Furthermore, this study extends the findings of Yucel‐Aybat and Kramer (20172018), namely that schadenfreude stemming from comparative advertising may increase liking for an advertised brand. Our research shows that direct comparison between brands or choice options is not necessary to trigger schadenfreude, nor does the actual performance of the chosen option need to be known to increase the evaluation of one's choice. Therefore, consumers will mistake positive feelings of schadenfreude as information about their own choice when they have no reason to believe that their chosen product is superior than someone else's failed product. This effect is also not driven by feelings of envy or jealousy toward another (Study 1). Study 2 shows that such misattribution is robust across categories, even where the unsatisfactory performance of another's purchased product cannot be compared to the performance of one's chosen item.
This study also adds to the literature on appraisal of emotions (Lazarus, 1991; Lerner & Keltner, 2000; Li et al., 2019; Morales, Wu, & Fitzsimons, 2012; Roseman & Smith, 2001; van Dijk et al., 2011). Schadenfreude occurs when people are concerned with the goal of maintaining self‐ and social‐esteem (Li et al., 2019; van Dijk et al., 2011). However, as the target of schadenfreude is another person, it can be appraised in terms of a specific appraisal dimension (theme) of certainty/uncertainty (Lerner & Keltner, 2000), leading to avoidance of uncertainty in choices (Kramer et al., 2011). This study, however, shows that overall pleasantness (positivity) of schadenfreude, another appraisal dimension, is used in judgments of one's own unrelated previous choices. Thus, drawing on the effect of the valence of the emotions, the present research contributes to the feelings‐as‐information theory (Schwarz, 2012) by identifying the specific, other‐caused emotion of schadenfreude that may be misconstrued as information about one's own (not the other's) unrelated choices. Study 3 underscores the automaticity of such misattribution (the effect disappears when consumers become aware of possible misattribution) and Study 2 indicates that temporal precedence is necessary for this misattribution to occur.

6.2 Managerial implications

Marketing communications practitioners and brand managers, in particular, may find our investigation to be of interest. Schadenfreude has found extensive use in advertising (Garfield, 2009; Luckerson, 2014; Nudd, 2011), and the present research explains why schadenfreude can enhance consumers' satisfaction with their already‐made purchases. For example, a consumer watching one of “Get a Mac” ads on their newly purchased Mac may become more satisfied with their Mac purchase. In a similar vein, a social media brand marketer might make available reviews or content (such as webcomics) about competing brands and capable of eliciting schadenfreude, thus increasing consumers' satisfaction with purchases of the promoted brand. Given that decision (choice) satisfaction is a strong predictor of consumer loyalty (Heitmann et al., 2007), which in turn contributes to a firm's financial performance (Ittner & Larcker, 1998), the findings of the present research should bear significance for practitioners.
Importantly, we also find that the effect of schadenfreude on choice satisfaction is not restricted to suggested failures involving comparable brands or products. An implication is that situations that do not involve comparable options may elicit schadenfreude leading to increased consumer choice satisfaction. To cite an example, Jet Blue's “Welcome Big Wigs” campaign makes fun of senior business executives (high in social status) flying on a budget. Such messaging could trigger schadenfreude among some consumers without resorting to direct comparisons with other brands (Garfield, 2009). Further, such non‐comparative advertising may be effective in increasing consumer choice satisfaction by means of evoking schadenfreude, so long as consumers are not aware that they may misattribute their feelings of schadenfreude to their own choices. In an online environment, viral prankvertising using acceptable targets (Luckerson, 2014) or other content featuring the downfall of high‐status individuals (e.g., news about politicians' criminal convictions) may be a tool used to elicit schadenfreude and reinforce consumer choice satisfaction. For example, an online store might feature a news piece about a famous person's tribulations after shopping checkout, prompting consumers to feel schadenfreude and unconsciously become more satisfied with the online purchase they just made.

6.3 Limitations and future research

The present research is not without limitations. First, it relies on the manipulation of schadenfreude toward a specific other (another consumer). Previous studies on schadenfreude have shown that it can be felt not only toward specific others (e.g., users of a competing brand) but also toward nonindividual entities, including competing brands themselves (Phillips‐Melancon & Dalakas, 2014) or rival sports teams (Leach et al., 2003). While the authors believe that there is no reason to expect that the effects observed in Studies 1, 2, and 3 should be different, replication of these studies by using nonindividual entities will enable scholars to examine the extent to which the current findings generalize.
Second, the present research adopted a previously successful manipulation of schadenfreude toward another consumer: their status purchase signaled higher social status and subsequent product failure elicited schadenfreude (Sundie et al., 2009). The authors believe this manipulation to be theoretically sound as it requires prior upward comparison with another consumer who is higher in social status and subsequent downward comparison when that consumer's purchase fails. Future research should test other manipulations of schadenfreude, for example, asking consumers to recall the instances when they felt schadenfreude toward someone (Kramer et al., 2011). Alternatively, to mimic some real‐life instances of schadenfreude, consumers may be shown a comparative ad featuring Caroline's tribulations with a competitor brand (cf., Yucel‐Aybat & Kramer, 2017), although the manipulations in Studies 1–3 are more general as they do not involve a direct comparison of choice options.
Further research may also study for how long the observed effects will persist. Will they live on until a consumer needs to repurchase a product (and thus choose their current product or a competitor product one more time) or will they dissipate by then? The answer to this question is likely to depend on the accessibility of feelings of schadenfreude at a particular point in time (Schwarz, 2012).
There may be a number of situational variables inherent in consumer purchases that may further moderate our observed effects. For example, a high degree of choice conflict (Chernev, Böckenholt, & Goodman, 2015) or of product involvement (Korgaonkar & Moschis, 1982; Olsen, 2007) should increase the observed effects, making consumers more likely to attend to positive information in their evaluations of their choices.
Individual differences may regulate how likely consumers are to apply feelings of schadenfreude to their judgments. For instance, need for cognition (Cacioppo & Petty, 1982; Haddock, Maio, Arnold, & Huskinson, 2008), need for affect (Maio & Esses, 2001), and consumer preference for intuitive–experiential or analytical–rational thinking styles (Epstein, Pacini, Denes‐Raj, & Heier, 1996) may also moderate the observed effects, as less affect‐driven consumers may scrutinize the source of their feelings and not incorporate them into their judgments. Finally, consumer high in the Dark Triad traits (narcissism, Machiavellianism, and especially psychopathy) are more inclined to feel schadenfreude (James, Kavanagh, Jonason, Chonody, & Scrutton, 2014) and thus may be more likely to feel more satisfied with their purchases when those of others fail.
Still, schadenfreude may be a complex emotion, but it need not sound grim. Schadenfreude is not always a sign of a dark personality. It is a commonly experienced emotion and it is often used in marketing. The authors thus invite further research into how consumers' satisfaction, judgment, and behavior may rest on their feeling happy for someone else's loss.

Cultural pressure and biased responding in free will attitudes

Cultural pressure and biased responding in free will attitudes. Emiel Cracco, Carlos González-García, Ian Hussey, Senne Braem and David Wisniewski. Royal Society Open Science, August 26 2020. https://doi.org/10.1098/rsos.191824

Abstract: Whether you believe free will exists has profound effects on your behaviour, across different levels of processing, from simple motor action to social cognition. It is therefore important to understand which specific lay theories are held in the general public and why. Past research largely focused on investigating free will beliefs (FWB, ‘Do you think free will exists?’), but largely ignored a second key aspect: free will attitudes (FWA, ‘Do you like/value will?’). Attitudes are often independently predictive of behaviour, relative to beliefs, yet we currently know very little about FWAs in the general public. One key issue is whether such attitudes are subject to biased, socially desirable responding. The vast majority of the general public strongly believes in the existence of free will, which might create cultural pressure to value free will positively as well. In this registered report, we used a very large (N = 1100), open available dataset measuring implicit and explicit attitudes towards free will and determinism to address this issue. Our results indicate that both explicit and implicit attitudes towards free will are more positive than attitudes towards determinism. We also show that people experience cultural pressure to value free will, and to devalue determinism. Yet, we found no strong evidence that this cultural pressure affected either implicit or explicit attitudes in this dataset.


4. Discussion

In this registered report, we investigated attitudes towards free will and determinism in a large lay sample for the first time. Using data from the AIID project, we analysed both explicit and implicit attitudes towards free will and determinism. Attitudes towards free will were generally positive, while attitudes towards determinism were generally negative. This finding was robust to changes in how explicit and implicit attitudes were computed from the data. We further showed that people experience cultural pressure to value free will, and to devalue determinism. Contrary to our hypotheses, this pressure did not seem to affect free will attitudes.

4.1. Mapping free will attitudes in the general public

There is much prior research demonstrating that free will beliefs are dynamic, i.e. that they can be manipulated experimentally [7,16,21,37]. Such experimental manipulations often lead only to small effects, and there is little research directly addressing why changing free will beliefs is so difficult. Furthermore, free will belief manipulations probably affect different people to a varying degree, and we currently do not know which variables make a person susceptible to such manipulations. One factor that might partly explain these open questions is people's attitudes towards free will. A person with highly positive attitudes towards free will is likely to be less affected by FWB manipulations than a person with more negative attitudes towards free will. In order to test this hypothesis, we first need to map out and understand FWAs in the general public, which has not been done to date, however.
Our results show that both implicit and explicit attitudes towards free will are strongly positive in the general public. Only 11.39% of the participants explicitly valued free will negatively, while 34% chose the most positive available attitude rating on the scale, which mirrors similar findings for FWBs [4,5]. Furthermore, a lower proportion of participants explicitly valued determinism positively (35.96%), which again mirrors weaker belief in determinism in previous studies [5]. Interestingly, the mode of the explicit attitude distribution was nevertheless 0, indicating that many participants indicated to value free will and determinism to an equal degree. The same was not true for the implicit attitude distribution, which had a clearly positive mode instead. Thus, although many people indicated that they valued free will and determinism to an equal degree, implicit measures suggested that they in fact valued free will more strongly.
Additionally, our data demonstrate that there is considerable variance in FWAs (both explicit and implicit). Taken together, these results suggest that FWAs are a potential mediator for FWB manipulations, and might help explain why such manipulations are generally weak. Of course, these conclusions are tentative at the moment and will have to be confirmed empirically. Specifically, further research will need to directly assess the relation of FWBs and FWAs, and whether FWAs act as a mediator for FWB manipulations.

4.2. Cultural pressure and free will attitudes

One untested assumption in the free will belief literature is that responses to free will questionnaires are unbiased by cultural pressure. Here, we showed that in the domain of free will attitudes, participants indeed report cultural pressure to value free will, as well as a cultural pressure to devalue determinism. We further show that cultural pressure is stronger on free will than it is on determinism. Given this fact, one might expect that this cultural pressure affects attitudes in some measurable way. To investigate this possibility, we tested if more self-reported pressure to value free will led to more positive FWAs and whether more self-reported pressure led to more diverging explicit and implicit FWAs, since we expected cultural pressure to affect explicit attitudes more strongly than implicit ones. Both of these analyses yielded no significant results, however, leading us to conclude that cultural pressure did not affect FWA measures in our sample.
Although unexpected, there are some potential explanations for this finding. One option is that the cultural pressure measure did not fully capture the desired construct (biased/pressured responding). In order to assess cultural pressure, we only used two items that were rather blunt (e.g. ‘There is cultural pressure to think positive things about free will.’). Biased responding is clearly a wider concept than just self-rated cultural pressure, and is often measured using whole scales like the Balanced Inventory of Desirable Responding (BIDR) [38], a 40-item scale that measures both ‘impression management’ and ‘self-deceptive enhancement’. Such measures are more nuanced and of higher psychometric quality than the two cultural pressure items used in our main analysis.
While the BIDR was also part of the AIID dataset, we chose to use the cultural pressure items because the available sample size (214 < n < 233) was much higher than for the BIDR (13 < n < 55), and because these items were directly related to free will and determinism, while the BIDR is a much more general trait measure. However, the BIDR impression management and self-deceptive enhancement scales were included in the exploratory analysis correlating FWAs with personality traits, and we assessed BIDR scores in additional non-preregistered analyses. Impression management, which is arguably closer to the cultural pressure items used in the main analysis, did not correlate with either explicit (r = 0.09, p = 0.77, n = 13) or implicit (r = 0.06, p = 0.69, n = 43) attitudes. Thus, even this alternative measure of ‘cultural pressure’ showed no significant results. In contrast, self-deceptive enhancement did correlate with explicit attitudes (r = 0.63, p = 0.02, n = 13), but not with implicit attitudes (r = −0.02, p = 0.86, n = 55). Thus, it might be that people who tend to hold exaggerated positive self-descriptions report more positive feelings towards free will, relative to determinism. This exploratory finding is based on a very small sample size though and should be interpreted with caution until is it replicated in an independent, larger sample. Clearly, more research on this is needed, but this already demonstrates that free will attitudes might still be biased, just not by self-rated cultural pressure.

4.3. Exploratory analyses

In additional registered exploratory analyses, we found that age was positively related to free will attitudes. Interestingly, this finding is not consistent with a recent report that free will beliefs do not change with age [5]. This points to an interesting dissociation between free will beliefs and free will attitudes with increasing age that should be addressed in the future.

4.4. Directions for future research

Despite the many interesting findings in the current dataset, there remain several key open questions that should be addressed. First, the methods for measuring implicit attitudes towards free will need to be further refined. While the IAT is a much used and well validated instrument, its design only allows the assessment of two concepts in direct opposition. The IAT treats free will and determinism as two endpoints on a single attitude scale: the more you value free will, the less you value determinism, and vice versa. We know from free will belief research, however, that believing in free will does not automatically translate into disbelieving determinism [5], in fact one can believe in both at the same time (compatibilism, [1]). Thus, it might be that people also value both free will and determinism positively, yet the IAT is ill-suited to detect this pattern of free will related attitudes. Additionally, we found IAT scores to be more strongly related to deliberate thoughts on free will, than they are to gut feelings on free will, a pattern of results that we did not expect. Lastly, the words used to describe free will (intention, freedom, choice), and determinism (fixed, destined, arranged) have many uses that have little to do with the philosophical concepts of either free will or determinism, and might not precisely capture them. For instance, ‘arranged’ is often used to describe arranging a meeting, which has little to do with physical determinism. Taken together, this suggests that future research should invest effort into developing alternative measures of implicit attitudes towards free will.
Second, methods for measuring explicit attitudes towards free will and determinism should also be refined, and the precise wording of the attitude items might need to be revised. Additional effort should be invested into the precise wording of the attitude items. The AIID project used a wide range of different explicit attitude items, and here we focused on valence items (‘How positive or negative do you feel towards free will/determinism?’). For research specifically focusing on free will, it might be that other items (e.g. ‘Having free will is important to me’) are better suited to capture free will attitudes. Additionally, in order to make explicit and implicit attitude measures comparable here, we computed a difference score from free will and determinism valence ratings (val_diff). While this is useful from a methodological perspective, this procedure suffers from some of the same issues as the free will IAT. Just as the IAT cannot detect people who value both free will and determinism positively, as some compatibilists might do, the val_diff items cannot do so either. In the future, explicit attitude items for free will and determinism should be investigated separately, to more easily identify compatibilist participants.
Third, future work should focus on investigating free will beliefs and attitudes simultaneously, in order to describe and explain their interactions. Here, we focused on attitudes only, but in order to understand belief attitude interaction, e.g. whether free will attitudes mediate effects of free will belief manipulations on behaviour, we need to assess beliefs and attitudes within the same participants. This would also allow us to test whether free will attitudes are conditional on specific free will beliefs (e.g. ‘I can only value free will if I believe in it’), or vice versa. Relatedly, data reported here have been acquired between 2005 and 2007, while much of the work on free will beliefs has been performed about a decade later [4,5]. Attitudes can change across time, which further emphasizes the necessity to acquire beliefs and attitudes simultaneously if we are to understand how these two aspects of lay views on free will interact.

Quiet Fires Fail to Impress: Introverted Expressions of Passion Receive Less Social Worth, so those who express their passion extravertedly are more likely to reach higher organizational echelons

Cormier, Grace, and Jon Jachimowicz. 2020. “Quiet Fires Fail to Impress: Introverted Expressions of Passion Receive Less Social Worth.” PsyArXiv. August 26. doi:10.31234/osf.io/3zg4c

Abstract: Thinking of passionate people typically brings to mind their vivacious expressions. Prior research has shown that such outward manifestations of passion are often met with increased admiration and support by others. But not everyone may express their passion so animatedly. Drawing on personality research, we argue that vivacious expressions of passion capture only a narrow set of passion expressions: those characteristic of extraversion. We suggest that passion is also expressed in ways more aligned with introversion. Based on emerging sociological perspectives, we subsequently propose that introverted expressions of passion are rewarded less social worth than extraverted expressions of passion. We provide empirical support across four studies with full-time employees (N=1,060), including a study of subordinate-supervisor pairs. Our theory and results highlight that interpersonal effects of passion depend on how passion is expressed, whereby those who express their passion extravertedly—but not introvertedly—are more likely to reach higher organizational echelons.


I find support for pure altruism because individuals who received additional Social Security benefits passed on 15.4 percent to children via inter vivos transfers without receiving any additional care in return

Intergenerational Altruism and Retirement Transfers: Evidence from the Social Security Notch. Anita Mukherjee. J. Human Resources August 6, 2020 0419-10140R3. http://jhr.uwpress.org/content/early/2020/08/11/jhr.58.1.0419-10140R3.abstract

Abstract: I contribute new evidence on altruistic preferences in intergenerational transfers using variation in Social Security benefits induced by an inflation-indexing mistake. The instrument is most relevant for those with low education, so I focus on this group. I find support for pure altruism because individuals who received additional Social Security benefits passed on 15.4 percent to children via inter vivos transfers without receiving any additional care in return. On the contrary, children reduce caregiving monotonically with increases in parental Social Security benefits. Adult female children appear to be the most affected as they both receive monetary transfers and reduce caregiving.


Adoptees: Parents’ over‐reactive and hostile parenting at 27 months were partially due to heritable (bio-mother internalizing problems and substance use) & prenatal factors (bio-mother illicit drug use during pregnancy)

Child Effects on Parental Negativity: The Role of Heritable and Prenatal Factors. Chang Liu et al. Child Development, Aug 1 2020. https://doi.org/10.1111/cdev.13404

Abstract: This study examined two possible mechanisms, evocative gene-environment correlation and prenatal factors, in accounting for child effects on parental negativity. Participants included 561 children adopted at birth, and their adoptive parents and birth parents within a prospective longitudinal adoption study. Findings indicated child effects on parental negativity, such that toddlers’ negative reactivity at 18 months was positively associated with adoptive parents’ over‐reactive and hostile parenting at 27 months. Furthermore, we found that child effects on parental negativity were partially due to heritable (e.g., birth mother [BM] internalizing problems and substance use) and prenatal factors (e.g., BM illicit drug use during pregnancy) that influence children’s negative reactivity at 18 months. This study provides critical evidence for “child on parent” effects.



From 2019... They used the spin precession of the Rb atoms as a clock to measure the time it takes them to cross the classically forbidden region; traversal time was 0.61(7) ms

Measurement of the time spent by a tunnelling atom within the barrier region. Ramón Ramos, David Spierings, Isabelle Racicot & Aephraim M. Steinberg. Nature volume 583, pages529–532(2020). Jul 22, 2020. https://www.nature.com/articles/s41586-020-2490-7

Abstract: Tunnelling is one of the most characteristic phenomena of quantum physics, underlying processes such as photosynthesis and nuclear fusion, as well as devices ranging from superconducting quantum interference device (SQUID) magnetometers to superconducting qubits for quantum computers. The question of how long a particle takes to tunnel through a barrier, however, has remained contentious since the first attempts to calculate it1. It is now well understood that the group delay2—the arrival time of the peak of the transmitted wavepacket at the far side of the barrier—can be smaller than the barrier thickness divided by the speed of light, without violating causality. This has been confirmed by many experiments3,4,5,6, and a recent work even claims that tunnelling may take no time at all7. There have also been efforts to identify a different timescale that would better describe how long a given particle spends in the barrier region8,9,10. Here we directly measure such a time by studying Bose-condensed 87Rb atoms tunnelling through a 1.3-micrometre-thick optical barrier. By localizing a pseudo-magnetic field inside the barrier, we use the spin precession of the atoms as a clock to measure the time that they require to cross the classically forbidden region. We study the dependence of the traversal time on the incident energy, finding a value of 0.61(7) milliseconds at the lowest energy for which tunnelling is observable. This experiment lays the groundwork for addressing fundamental questions about history in quantum mechanics: for instance, what we can learn about where a particle was at earlier times by observing where it is now11,12,13.

Abstract: Tunnelling is one of the most paradigmatic and evocative phenomena of quantum physics, underlying processes such as photosynthesis and nuclear fusion, as well as devices ranging from SQUID magnetometers to superconducting qubits for quantum computers. The question of how long a particle takes to tunnel, however, has remained controversial since the first attempts to calculate it, which relied on the group delay. It is now well understood that this delay (the arrival time of the transmitted wave packet peak at the far side of the barrier) can be smaller than the barrier thickness divided by the speed of light, without violating causality. There have been a number of experiments confirming this, and even a recent one claiming that tunnelling may take no time at all. There have also been efforts to identify another timescale, which would better describe how long a given particle spends in the barrier region. Here we present a direct measurement of such a time, studying Bose-condensed 87Rb atoms tunnelling through a 1.3-μm thick optical barrier. By localizing a pseudo-magnetic field inside the barrier, we use the spin precession of the atoms as a clock to measure the time it takes them to cross the classically forbidden region. We find a traversal time of 0.62(7) ms and study its dependence on incident energy. In addition to finally shedding light on the fundamental question of the tunnelling time, this experiment lays the groundwork for addressing deep foundational questions about history in quantum mechanics: for instance, what can we learn about where a particle was at earlier times by observing where it is now?



In the American and Dutch samples, we found that optimism increased across younger adulthood, plateaued in midlife, and then decreased in older adulthood

Changes in optimism and pessimism in response to life events: Evidence from three large panel studies. William J. Chopik et al. Journal of Research in Personality, Volume 88, October 2020, 103985. https://doi.org/10.1016/j.jrp.2020.103985

Abstract: Although individuals vary in how optimistic they are about the future, one assumption that researchers make is that optimism is sensitive to changes in life events and circumstances. We examined how optimism and pessimism changed across the lifespan and in response to life events in three large panel studies (combined N = 74,886). In the American and Dutch samples, we found that optimism increased across younger adulthood, plateaued in midlife, and then decreased in older adulthood. In the German sample, there were inconsistent results with respect to age differences and mean level changes in optimism. Associations between life events and changes in optimism/pessimism were inconsistent across samples. We discuss our results in the context of life events and lifespan development.

Honesty-Humility (HH) is negatively linked to dishonest behavior; the HH-dishonesty link is unaffected by the utility of incentives (irrespective of incentive size or a gain-vs-loss framing)

On the robustness of the association between Honesty-Humility and dishonest behavior for varying incentives. Sina A. Klein et al. Journal of Research in Personality, Volume 88, October 2020, 104006. https://doi.org/10.1016/j.jrp.2020.104006

Highlights
• Honesty-Humility (HH) is negatively linked to dishonest behavior.
• The HH-dishonesty link is unaffected by the utility of incentives.
• This finding replicates for incentive size and different framing of incentives.

Abstract: Previous research consistently showed a negative link between Honesty-Humility (HH) and dishonest behavior. However, most prior research neglected the influence of situational factors and their potential interaction with HH. In two incentivized experiments (N = 322, N = 552), we thus tested whether the (subjective) utility of incentives moderates the HH-dishonesty link. Replicating prior evidence, HH showed a consistent negative link to dishonesty. However, the utility of incentives did not moderate this association, neither when manipulated through incentive size (BF01 = 5.7) nor when manipulated through gain versus loss framing (BF01 = 20.4). These results demonstrate the robustness of the HH-dishonesty link.
