Simpson B, Mesler RM, White K. Perceiving less but wasting more: The relationship between perceived resource scarcity and consumer food waste. Appetite 2024; 202:107642. [PMID: 39179108 DOI: 10.1016/j.appet.2024.107642] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2024] [Revised: 08/12/2024] [Accepted: 08/19/2024] [Indexed: 08/26/2024]
Abstract
Consumers' food-related behaviors often culminate in significant food waste. Surprisingly however, limited attention has been given to psychological reasons why this occurs. Across four studies, this research suggests that, because perceived resource scarcity activates a resource acquisition goal, under conditions where product scarcity is not present it leads consumers to engage in inaccurate over-acquisition of resources (i.e., food), resulting in greater waste. Studies 1a (quasi-experimental field study) and 1b (lab experiment) test the role of perceived resource scarcity in predicting food acquisition and waste. Studies 2a and 2b are correlational and measure household food waste to demonstrate that resource acquisition accuracy mediates the relationship between perceived resource scarcity and food waste.

Abstract
OBJECTIVE To evaluate whether an integrated mental health video consultation approach (PROVIDE model) can improve symptoms compared with usual care in adults with depression and anxiety disorders attending primary care. DESIGN Assessor masked, multicentre, randomised controlled trial (PROVIDE-C). SETTING In 29 primary care practices in Germany, working remotely online from one trial hub. PARTICIPANTS 376 adults (18-81 years) who presented to their general practitioner (GP) with depression or anxiety, or both. INTERVENTION Participants were randomised (1:1) to receive the PROVIDE model (n=187) or usual care (n=189). Usual care was provided by GPs through interventions such as brief counselling and psychotropic medication prescriptions and may or may not have included referrals to mental health specialists. The PROVIDE model comprised transdiagnostic treatment provided through five real-time video sessions between the patient at the primary care practice and a mental health specialist at an offsite location. MAIN OUTCOME MEASURES The primary outcome was the absolute change in the mean severity of depressive and anxiety symptoms measured using the patient health questionnaire anxiety and depression scale (PHQ-ADS) at six months, in the intention-to-treat population. Secondary outcomes, measured at six and 12 months, included PHQ-ADS subscores, psychological distress related to somatic symptoms, recovery, health related quality of life, quality and patient centredness of chronic illness care, and adverse events. RESULTS Between 24 March 2020 and 23 November 2021, 376 patients were randomised into treatment groups. Mean age was 45 years (standard deviation (SD) 14), 63% of the participants were female, and mean PHQ-ADS-score was 26 points (SD 7.6). Compared with usual care, the PROVIDE intervention led to improvements in severity of depressive and anxiety symptom (adjusted mean change difference in the PHQ-ADS score -2.4 points (95% confidence interval -4.5 to -0.4), P=0.02) at six months. The effects were sustained at 12 months (-2.9 (-5.0 to -0.7), P<0.01). No serious adverse events were reported in either group. CONCLUSIONS Through relatively low intensity treatment, the PROVIDE model led to a decrease in depressive and anxiety symptoms with small effects in the short and long term. Depression and anxiety disorders are prevalent and therefore the small effect might cumulatively impact on population health in this population. TRIAL REGISTRATION ClinicalTrials.gov NCT04316572.

Abstract
People ubiquitously smile during brief interactions and first encounters, and when posing for photos used for virtual dating, social networking, and professional profiles. Yet not all smiles are the same: subtle individual differences emerge in how people display this nonverbal facial expression. We hypothesized that idiosyncrasies in people's smiles can reveal aspects of their personality and guide the personality judgments made by observers, thus enabling a smiling face to serve as a valuable tool in making more precise inferences about an individual's personality. Study 1 (N = 303) supported the hypothesis that smile variation reveals personality, and identified the facial-muscle activations responsible for this leakage. Study 2 (N = 987) found that observers use the subtle distinctions in smiles to guide their personality judgments, consequently forming slightly more accurate judgments of smiling faces than neutral ones. Smiles thus encode traces of personality traits, which perceivers utilize as valid cues of those traits.

Vendemia MA. Sexual objectification versus empowerment: Examining the effects of sexualized women's facial expression on viewers' evaluations of social cognition and self-objectification.

Abstract
Objectification scholarship highlights how traditional media portrayals oftentimes direct attention toward women's bodies and away from their faces which communicate important social information. This study sought to investigate how thin-ideal, white women's facial expression potentially attenuates the negative effects of appearing in a sexually objectifying manner using validated imagery. In a 2 × 3 between-subjects experiment (N = 1001 U.S. adult women; Mage = 42.56, SDage = 12.72), portraits of women varied in their sexualization (non-sexualized vs. sexualized) and facial expression (neutral expression, low-intensity smiling, high-intensity smiling) to better understand how these factors influence dimensions of social cognition (competence, warmth, authenticity), self-promotional attributions, and viewers' own self-objectification. Results revealed that viewers rated sexualized (vs. non-sexualized) women lower in competence and authenticity, as well ascribed more self-promotional explanations for their behavior. Moreover, exposure to sexualized women heightened viewers' self-objectification, regardless of facial expression. Results also indicated that smiling intensity positively influenced viewers' ratings of social cognition. However, there is little evidence that smiling intensity overrides the negative effects of sexualization. Implications for the sexual objectification of women are discussed.

Abstract
Co-twin studies are an elegant and powerful design that allows controlling for the effect of confounding variables, including genetic and a range of environmental factors. There are several approaches to carry out this design. One of the methods commonly used, when contrasting continuous variables, is to calculate difference scores between members of a twin pair on two associated variables, in order to analyse the covariation of such differences. However, information regarding whether and how the different ways of estimating within-pair difference scores may impact the results is scant. This study aimed to compare the results obtained by different methods of data transformation when performing a co-twin study and test how the magnitude of the association changes using each of those approaches. Data was simulated using a direction of causation model and by fixing the effect size of causal path to low, medium, and high values. Within-pair difference scores were calculated as relative scores for diverse within-pair ordering conditions or absolute scores. Pearson's correlations using relative difference scores vary across the established scenarios (how twins were ordered within pairs) and these discrepancies become larger as the within-twin correlation increases. Absolute difference scores tended to produce the lowest correlation in every condition. Our results show that both using absolute difference scores or ordering twins within pairs, may produce an artificial decrease in the magnitude of the studied association, obscuring the ability to detect patterns compatible with causation, which could lead to discrepancies across studies and erroneous conclusions.

Abstract
Research on the use of sex toys has been primarily performed from a medical perspective, while there is still limited research from a psychosocial perspective. To bridge this gap, in this study we examined whether some psychosocial variables might be linked to sex toy ownership in a sample of 3960 Italian (cisgender men and women) sex toy buyers. More specifically, we investigated the association between gender identities and ideologies and the variety and types of sex toys owned. Based on the data, we detected two dimensions underlying the ownership of sex toys: (1) orientation to owning kinky sex toys and (2) orientation to owning clit-oriented sex toys. Results showed that benevolent sexism and gender system justification were negatively correlated with owning clit-oriented toys. Moreover, strongly gender-identified participants owned a small variety of different toys and preferred toys that were designed to stimulate the vagina or clitoris over less commonly-used toys. No significant correlation between feminist identification and sex toy type owned was found when gender identification was taken into account. These results suggest that the owning of sex toys might be associated with traditional gender ideology and the strength of gender identification.

Abstract
Pain is essential for survival, but individual responses to painful stimuli vary, representing a complex interplay between sensory, cognitive, and affective factors. Individual differences in personality traits and in pain perception covary but it is unclear which traits play the most significant role in understanding the pain experience and whether this depends on pain modality. A systematic search identified 1534 records (CINAHL, MEDLINE, PsycInfo, PubMed and Web of Science), of which 22 were retained and included in a systematic review. Only studies from the pressure pain domain (n=6) could be compared in a formal meta-analysis to evaluate the relationship between Big Five traits and experimental pain. Pressure pain tolerance correlated positively with Extraversion and negatively with Neuroticism with a trivial effect size (<0.1). While these findings suggest personality might be only weakly related to pain in healthy individuals, we emphasize the need to consider standardization, biases, and adequate sample sizes in future research, as well as additional factors that might affect experimental pain sensitivity.

Abstract
INTRODUCTION This study investigates the relationship between cognitive functioning and 59 modifiable and intrinsic factors at the cusp of midlife. METHODS We analyzed data from 1221 participants in the Colorado Adoption/Twin Study of Lifespan behavioral development and cognitive aging (CATSLife; Mage = 33.20, %Female = 52.74). We assessed the impact of 59 factors on cognitive functioning using regularized regression and co-twin control models, controlling for earlier-life cognitive functioning and gray matter volume. RESULTS Eight robust factors were identified, including education attainment, cognitive complexity, purpose-in-life, and smoking status. Twins reporting higher levels of cognitive complexity and purpose-in-life showed better cognitive performance than their cotwin, while smoking was negatively associated. Using meta-analytically derived effect size threshold, we additionally identified that twins experiencing more financial difficulty tend to perform less well compared with their cotwin. DISCUSSION The findings highlight the early midlife link between cognitive functioning and lifestyle/psychological factors, beyond prior cognitive performance, brain status, genetic and familial confounders. Our results further highlight the potential of established adulthood as a crucial window for dementia prevention interventions targeting lifestyle and psychosocial factors. Highlights Cog complexity(+), purpose-in-life(+) were associated with cognition in early midlife.Smoking(-) was also associated with cognition in early midlife.Results were consistent controlling for genetic and environmental confounds.Association between EA and cognition might be mostly genetic and familial confounded.

Abstract
This study tested whether adolescents who perceived less household chaos in their family's home than their same-aged, same-sex sibling achieved more favorable developmental outcomes in young adulthood, independent of parent-reported household chaos and family-level confounding. Data came from 4,732 families from the Twins Early Development Study, a longitudinal, U.K.-population representative cohort study of families with twins born in 1994 through 1996 in England and Wales. Adolescents who reported experiencing greater household chaos than their sibling at the age of 16 years suffered significantly poorer mental-health outcomes at the age of 23 years, independent of family-level confounding. Mental-health predictions from perceived household chaos at earlier ages were not significant, and neither were predictions for other developmental outcomes in young adulthood, including socioeconomic status indicators, sexual risk taking, cannabis use, and conflict with the law. The findings suggest that altering children's subjective perceptions of their rearing environments may help improve their adult mental health.

Abstract
OBJECTIVE In high-income countries, people with low socio-economic status (SES) engage in less leisure-time physical activity (PA) than those with higher SES. Beyond a materialistic account of this difference, the role of motivational precursors-among which attitudes are emblematic-remains poorly understood, particularly when it comes to dissociating the automatic vs. deliberative components of attitudes. This pre-registered study aimed to examine the associations between SES (i.e. income and educational attainment) and motivational precursors of PA (i.e. explicit and implicit attitudes), and whether gender and age may moderate these relationships. METHOD We used data from 970 adults (64% of women; mean age = 33 ± 12 years) from the Attitudes, Identities, and Individual Differences (AIID) study. RESULTS Results of multiple linear regression analyses showed that participants with the highest level of income (>150,000$ per year) reported more positive explicit and implicit attitudes towards PA than those with lower income. Exploratory analysis further showed that women reported weaker explicit attitudes towards PA, while both explicit and implicit attitudes towards PA became weaker at age increases. In contrast, educational attainment was not significantly associated with those attitudes, and there was only mixed evidence for a moderating role of participants' gender on the pattern of associations. CONCLUSION Our findings suggest that both the explicit and implicit attitudes towards PA may be socially patterned. Future intervention studies should examine whether these attitudinal differences could be reduced, and whether such a reduction could help buffer the unequal participation in PA behaviors across social groups.

Abstract
Humans can extract statistical regularities of the environment to predict upcoming events. Previous research recognized that implicitly acquired statistical knowledge remained persistent and continued to influence behavior even when the regularities were no longer present in the environment. Here, in an fMRI experiment, we investigated how the persistence of statistical knowledge is represented in the brain. Participants (n = 32) completed a visual, four-choice, RT task consisting of statistical regularities. Two types of blocks constantly alternated with one another throughout the task: predictable statistical regularities in one block type and unpredictable ones in the other. Participants were unaware of the statistical regularities and their changing distribution across the blocks. Yet, they acquired the statistical regularities and showed significant statistical knowledge at the behavioral level not only in the predictable blocks but also in the unpredictable ones, albeit to a smaller extent. Brain activity in a range of cortical and subcortical areas, including early visual cortex, the insula, the right inferior frontal gyrus, and the right globus pallidus/putamen contributed to the acquisition of statistical regularities. The right insula, inferior frontal gyrus, and hippocampus as well as the bilateral angular gyrus seemed to play a role in maintaining this statistical knowledge. The results altogether suggest that statistical knowledge could be exploited in a relevant, predictable context as well as transmitted to and retrieved in an irrelevant context without a predictable structure.

Abstract
In line with the "beautiful-is-good" heuristic, numerous studies show that physically attractive individuals are perceived in a more positive light. However, building on previous findings suggesting that the "beauty-good" relationship is bidirectional, the present research investigates how information on a stigmatized attribute impacts attractiveness perceptions and social judgments. Within a controlled experimental design, we present evidence that the mere label of mental illness (i.e., schizophrenia) decreased the positivity of personality evaluations and perceived attractiveness of a male target that had previously been validated to be highly attractive. Consistent with the "good-is-beautiful" heuristic, a mental illness label led to decreased perceptions of attractiveness, which was mediated by the inference of less positive personality characteristics. This finding lends further support for the bidirectional nature of the "beauty-good" relationship and provides a valuable avenue for future research on the multifaceted ways in which the stigma of mental illness affects social perceptions.

Abstract
Although the perception of justice is a core need of all individuals, the adaptive value of belief in a just world (BJW)-in everyday life and when facing severe distress-has been typically investigated in separate studies. In this article, we tested, in only one study, the possibility that BJW can be a personal resource and a coping resource. We analysed data from the European Social Survey comprised of random representative samples of 27 European countries (N = 24,776 participants). We considered distressing circumstances both at an individual level (health impairment and financial difficulty) and at a macroeconomic contextual level. The results showed that for people both facing and not facing financial or health-related distress, BJW was positively associated with well-being, supporting BJW as a personal resource. Furthermore, we found that the decrease of well-being of people facing distress, both at an individual level and at a contextual level, compared to people not facing distress, was lower for individuals with higher BJW than for individuals with lower BJW, supporting BJW as a coping resource.

Abstract
Physiological, neurocognitive, and psychological changes facilitates adaptation to motherhood. This cross-sectional study aimed to examine differences between pregnant and non-pregnant women in affective cognitive and psychophysiological responses to infant stimuli. We hypothesized that pregnant women would display (I) reduced negative emotional reactivity and perception of distressed infant stimuli, (II) increased attention toward infants compared to adults, and (III) greater psychophysiological response to infant distress. The sample comprised 22 pregnant women (22-38 weeks gestation) and 18 non-pregnant nulliparous women. Four computerized tasks were administered to measure affective cognitive processing of infant stimuli, while recording facial expressions, electrodermal activity, and eye gazes. Results indicated that pregnant women exhibited fewer negative facial expressions, reported less frustration when exposed to distressed infant cries, and showed greater attention to emotional infant faces compared to non-pregnant women, but the differences did not remain statistically significant after correction for multiple comparisons. No differences were observed in psychophysiological responses. The findings indicate a possible pregnancy-mediated effect regarding the cognitive processing of infant stimuli, potentially as preparation for motherhood. Future research with larger samples and longitudinal design is needed to understand the predictors, timing, and plasticity of cognitive changes during pregnancy.

Abstract
Greedy phenomena have dramatically increased in societies. However, despite the universality of greedy behaviour, empirical research on the causes of greed is scarce. In this context, we propose that perceived economic inequality may be an important factor influencing greed. Study 1 provided primary evidence of a positive relationship between perceived economic inequality and greed, based on data from a large-scale social survey (CFPS 2018, N = 14,317). Employing well-established questionnaires, Study 2A (N = 200) and Study 2B (N = 399) revealed that perceived economic inequality positively predicts greed, with relative deprivation playing a mediating role. Study 3A (N = 200) and Study 3B (N = 200) manipulated perceived economic inequality to provide causal evidence of its effects on greed and to replicate the mediating effect of relative deprivation. Finally, Study 4 (N = 372), using a blockage manipulation design, showed that the effect of perceived economic inequality on greed significantly decreases when relative deprivation is suppressed. In summary, the results of these six studies consistently suggest that perceived economic inequality positively affects greed and that this effect is mediated by relative deprivation.

Abstract
People regularly form one-sided, "parasocial" relationships (PSRs) with targets incapable of returning the sentiment. Past work has shown that people engage with PSRs to support complex psychological needs (e.g., feeling less lonely after watching a favorite movie). However, we do not know how people rate these relationships relative to traditional two-sided relationships in terms of their effectiveness in supporting psychological needs. The current research (Ntotal = 3085) examined how PSRs help people fulfil emotion regulation needs. In Studies 1 and 2, participants felt that both their YouTube creator and non-YouTube creator PSRs were more effective at fulfilling their emotional needs than in-person acquaintances, albeit less effective than close others. In Study 3, people with high self-esteem thought PSRs would be responsive to their needs when their sociometer was activated, just as they do with two-sided relationships.

Abstract
Social relationships influence physical health, yet questions remain regarding the nature of this association. For instance, when it comes to predicting health-relevant processes in daily life, few studies have examined (a) the relative importance of both positive and negative relational experiences, and (b) variability in relational experiences (in addition to mean levels). To address these gaps, we conducted a daily study (N = 4,005; ~ 30,000 observations) examining relationships, stress, and physiology in daily life. Heart rate and blood pressure were assessed using an optic sensor and integrated with an app-based study. Results demonstrated that higher mean levels of positive and lower mean levels of negative relational experiences predicted lower stress, better coping, and better physiological functioning in daily life, such as lower systolic blood pressure reactivity. Greater variability in negative (but not positive) relational experiences predicted lower stress, better coping, and lower systolic blood pressure reactivity.

Abstract
PROBLEM There is limited understanding and contradictory results regarding the contribution of the pregnant bodily experience to antenatal attachment. BACKGROUND Antenatal attachment is an important aspect of pregnancy, which has been linked with positive maternal and infant outcomes. Given the profound physical process of pregnancy, it is likely that bodily experience is implicated in antenatal attachment, with research supporting the involvement of pregnancy body (dis)satisfaction. However, previous research reveals conflicting results and has only focused on exteroceptive bodily experience (appearance) rather than internal physiological sensations (interoception). AIM To examine the relative contributions of both external and internal bodily experience in antenatal attachment. METHODS This cross-sectional study collected online survey data from 159 pregnant participants with measures capturing interoceptive sensibility (subjective experience of interoception), pregnancy body dissatisfaction and antenatal attachment. FINDINGS We replicated previous findings that pregnancy body dissatisfaction is related to antenatal attachment. However, the relationship between pregnancy body dissatisfaction and antenatal attachment was moderated by worry about interoceptive signals. The interoceptive construct of body trust was most strongly associated with antenatal attachment. DISCUSSION The results suggest that interoception is important for antenatal attachment, particularly feelings of body trust. Moreover, for individuals who were less worried about bodily sensations, high levels of body dissatisfaction were associated with low attachment scores, whilst for those who were more concerned about these sensations, the relationship between body dissatisfaction and antenatal attachment was mitigated. CONCLUSION The results suggest that focusing on internal sensations may be a protective strategy against pregnancy body dissatisfaction to strengthen maternal bonds.

Abstract
Given the increasing number of studies in various disciplines using experience sampling methods, it is important to examine compliance biases because related patterns of missing data could affect the validity of research findings. In the present study, a sample of 592 participants and more than 25,000 observations were used to examine whether participants responded to each specific questionnaire within an experience sampling framework. More than 400 variables from the three categories of person, behavior, and context, collected multi-methodologically via traditional surveys, experience sampling, and mobile sensing, served as predictors. When comparing different linear (logistic and elastic net regression) and non-linear (random forest) machine learning models, we found indication for compliance bias: response behavior was successfully predicted. Follow-up analyses revealed that study-related past behavior, such as previous average experience sampling questionnaire response rate, was most informative for predicting compliance, followed by physical context variables, such as being at home or at work. Based on our findings, we discuss implications for the design of experience sampling studies in applied research and future directions in methodological research addressing experience sampling methodology and missing data.

Abstract
Social media impacts people's wellbeing in different ways, but relatively little is known about why this is the case. Here we introduce the construct of "social media sensitivity" to understand how social media and wellbeing associations differ across people and the contexts in which these platforms are used. In a month-long large-scale intensive longitudinal study (total n = 1632; total number of observations = 120,599), we examined for whom and under which circumstances social media was associated with positive and negative changes in social and affective wellbeing. Applying a combination of frequentist and Bayesian multilevel models, we found a small negative average association between social media use AND subsequent wellbeing, but the associations were heterogenous across people. People with psychologically vulnerable dispositions (e.g., those who were depressed, lonely, not satisfied with life) tended to experience heightened negative social media sensitivity in comparison to people who were not psychologically vulnerable. People also experienced heightened negative social media sensitivity when in certain types of places (e.g., in social places, in nature) and while around certain types of people (e.g., around family members, close ties), as compared to using social media in other contexts. Our results suggest that an understanding of the effects of social media on wellbeing should account for the psychological dispositions of social media users, and the physical and social contexts surrounding their use. We discuss theoretical and practical implications of social media sensitivity for scholars, policymakers, and those in the technology industry.

Abstract
This study investigated whether there was community support for prominent gambling harm reduction policies, as well as perceived responsibility for electronic gambling machine (EGM) related harm in an Australian sample (n = 906). Using a randomised experimental design, we also explored whether these outcomes were influenced by three alternative explanations for EGM-related harm: a brain-based account of gambling addiction, an account that highlighted the intentional design of the gambling environment focused on the "losses disguised as wins" (LDWs), and a media release advocating against further government intervention in the gambling sector. We observed clear majority support for most policies presented, including mandatory pre-commitment, self-exclusion, and a $1 limit on EGM bets. A substantial majority of participants agreed that individuals, governments, and industry should be held responsible for EGM-related harm. Participants presented with the explanation of LDWs attributed greater responsibility for gambling-related harm to industry and government, less agreement that electronic gambling machines are fair, and more agreement that EGMs are likely to mislead or deceive consumers. There was some limited evidence of greater support for policy intervention in this group, including a blanket ban of EGMs, clinical treatment funded by gambling taxes, mass media campaigns, and mandatory pre-commitment for EGMs. We found no evidence that a brain-based account of gambling addiction substantially undermined support for policy intervention. We predicted that the information about LDWs and the brain-based account of EGM related harm would soften attributions of personal responsibility for gambling harm. Our results did not support either of these predictions.

Abstract
An accurate estimation of COVID-19 contagion risk is important in terms of understanding the dynamic of disease transmission and health behavior. Previous research has documented that many health-related variables influence the risk estimation of communicable diseases. We expanded the current understanding by investigating whether health-irrelevant factors-such as one's sense of power-can have a systematic and consequential impact on perceived risks of catching the coronavirus. Based on the social distance theory of power, we propose that people in a higher power position develop a greater sense of social distance than those in a lower power position, which may in turn predispose the former to think that they are less likely to catch contagious diseases from other people. In Study 1, we provided correlational evidence that the personal sense of power was associated with the underestimation of contagion probability in Chinese university students. In Study 2, we established the causal relationship between power and concerns for contagious diseases in nonstudent adults and revealed the mediating role of social distance in the observed effect. Overall, these results, for the first time, indicate that power can elevate perceived social distance, exerting downstreaming effects on health cognition during the COVID-19 pandemic.

Abstract
OBJECTIVE There is a lack of clarity regarding the developmental mechanisms underlying moral disengagement (a typical moral personality) at the within-person level. To address this issue, we explore the serial cascade effect of cybervictimization and hostile rumination. METHOD The longitudinal relationships between cybervictimization, hostile rumination, and moral disengagement were explored among 1146 undergraduates, assessed four times (T1-T4) across 2 years. RESULTS The random intercept cross-lagged panel model (RI-CLPM) analysis revealed that the random intercepts of all variables were positively associated with each other. At the within-person level, cybervictimization at T2 indirectly predicted subsequent changes in moral disengagement at T4 through changes in hostile rumination at T3 (the indirect effect was 0.02); furthermore, moral disengagement at T3 predicted changes in hostile rumination at T4 (β = 0.091). CONCLUSIONS The within-person dynamics of moral disengagement should be partly due to the serial effect of cybervictimization and hostile rumination, whereas hostile rumination and moral disengagement may form a developmental cascade to some degree. These findings and the proposed serial cascade model of moral disengagement could expand our understanding of the developmental mechanism of moral personality. Additionally, caution must be exercised as this study exhibits seemingly small effect sizes and inconsistent results.

Abstract
OBJECTIVE Personality traits cluster across countries, regions, cities, and neighborhoods. What drives the formation of these clusters? Ecological theory suggests that physical locations shape humans' patterns of behaviors and psychological characteristics. Based on this theory, we examined whether and how differential land-cover relates to individual personality. METHOD We followed a preregistered three-pronged analysis approach to investigate the associations between personality (N = 2,690,878) and land-cover across the United States. We used eleven land-cover categories to classify landscapes and tested their association with personality against broad physical and socioeconomic factors. RESULTS Urban areas were positively associated with openness to experience and negatively associated with conscientiousness. Coastal areas were positively associated with openness to experience and neuroticism but negatively associated with agreeableness and conscientiousness. Cultivated areas were negatively associated with openness. Landscapes at the periphery of human activity, such as shrubs, bare lands, or permanent snows, were not reliably associated with personality traits. CONCLUSIONS Bivariate correlations, multilevel, and random forest models uncovered robust associations between landscapes and personality traits. These findings align with ecological theory suggesting that an individual's environment contributes to their behaviors, thoughts, and feelings.

Abstract
Delay discounting-the extent to which individuals show a preference for smaller immediate rewards over larger delayed rewards-has been proposed as a transdiagnostic neurocognitive process across mental health conditions, but its examination in relation to posttraumatic stress disorder (PTSD) is comparatively recent. To assess the aggregated evidence for elevated delay discounting in relation to posttraumatic stress, we conducted a meta-analysis on existing empirical literature. Bibliographic searches identified 209 candidate articles, of which 13 articles with 14 independent effect sizes were eligible for meta-analysis, reflecting a combined sample size of N = 6897. Individual study designs included case-control (e.g. examination of differences in delay discounting between individuals with and without PTSD) and continuous association studies (e.g. relationship between posttraumatic stress symptom severity and delay discounting). In a combined analysis of all studies, the overall relationship was a small but statistically significant positive association between posttraumatic stress and delay discounting (r = .135, p < .0001). The same relationship was statistically significant for continuous association studies (r = .092, p = .027) and case-control designs (r = .179, p < .001). Evidence of publication bias was minimal. The included studies were limited in that many did not concurrently incorporate other psychiatric conditions in the analyses, leaving the specificity of the relationship to posttraumatic stress less clear. Nonetheless, these findings are broadly consistent with previous meta-analyses of delayed reward discounting in relation to other mental health conditions and provide further evidence for the transdiagnostic utility of this construct.

Abstract
Disasters cause sweeping damage, hardship, and loss of life. In this article, we first consider the dominant psychological approach to disasters and its narrow focus on psychopathology (e.g., posttraumatic stress disorder). We then review research on a broader approach that has identified heterogeneous, highly replicable trajectories of outcome, the most common being stable mental health or resilience. We review trajectory research for different types of disasters, including the COVID-19 pandemic. Next, we consider correlates of the resilience trajectory and note their paradoxically limited ability to predict future resilient outcomes. Research using machine learning algorithms improved prediction but has not yet illuminated the mechanism behind resilient adaptation. To that end, we propose a more direct psychological explanation for resilience based on research on the motivational and mechanistic components of regulatory flexibility. Finally, we consider how future research might leverage new computational approaches to better capture regulatory flexibility in real time.

Abstract
Understanding how youth perceive household economic hardship and how it relates to their behavior is vital given associations between hardship and behavioral development. Yet, most studies ignore youth's own perceptions of economic hardship, instead relying solely on caregiver reports. Moreover, the literature has tended to treat economic hardship as a stable force over time, rather than a volatile one that varies month-to-month. This study addressed extant limitations by collecting monthly measures of economic hardship, specifically caregiver- and youth-reported material deprivation and youth-reported financial stress, and youth internalizing and externalizing problems from 104 youth-caregiver dyads (youth: 14-16 years, 55% female, 37% Black, 43% White) over nine months. We examined month-to-month variability of these constructs and how youth-reports of material deprivation and financial stress predicted their behavior problems, controlling for caregiver-reports of material deprivation. We found that hardship measures varied month-to-month (ICCs = 0.69-0.73), and youth-reported material deprivation positively predicted internalizing when examining both within- and between-individual variability (β = .19-.47). Youth-reported financial stress positively predicted within-individual variation in externalizing (β = .18), while youth reports of material deprivation predicted externalizing when looking between families (β = .41). Caregiver-reported material deprivation was unrelated to youth behavior when accounting for youth perceptions of economic hardship.

Abstract
In the context of international migration, intergroup contact has been widely recognised as a strategy for enhancing host populations' positive attitudes towards immigrants. However, the moderating factors that influence this association have been relatively understudied. In this research, we propose that generalised trust plays a significant role as a moderator in the relationship between the quality and quantity of intergroup contact and the positive attitudes of Chileans towards Peruvian and Venezuelan immigrants. We hypothesize that both types of contact will be associated with more positive attitudes towards immigrants in hosts with generalised trust (vs. no generalised trust). Using a sample of 916 Chilean participants, we conducted a linear regression analysis to test our hypotheses, and results show us a moderation effect only with contact quality. These findings have theoretical and practical implications, particularly in understanding how the moderation effect of generalised trust can contribute to improving intergroup attitudes.

Abstract
BACKGROUND It is unclear whether a hypothetical intervention targeting either psychosocial well-being or emotion-driven impulsiveness is more effective in reducing unhealthy food choices. Therefore, we aimed to compare the (separate) causal effects of psychosocial well-being and emotion-driven impulsiveness on European adolescents' sweet and fat propensity. METHODS We included 2,065 participants of the IDEFICS/I.Family cohort (mean age: 13.4) providing self-reported data on sweet propensity (score range: 0 to 68.4), fat propensity (range: 0 to 72.6), emotion-driven impulsiveness using the UPPS-P negative urgency subscale, and psychosocial well-being using the KINDLR Questionnaire. We estimated, separately, the average causal effects of psychosocial well-being and emotion-driven impulsiveness on sweet and fat propensity applying a semi-parametric doubly robust method (targeted maximum likelihood estimation). Further, we investigated a potential indirect effect of psychosocial well-being on sweet and fat propensity mediated via emotion-driven impulsiveness using a causal mediation analysis. RESULTS If all adolescents, hypothetically, had high levels of psychosocial well-being, compared to low levels, we estimated a decrease in average sweet propensity by 1.43 [95%-confidence interval: 0.25 to 2.61]. A smaller effect was estimated for fat propensity. Similarly, if all adolescents had high levels of emotion-driven impulsiveness, compared to low levels, average sweet propensity would be decreased by 2.07 [0.87 to 3.26] and average fat propensity by 1.85 [0.81 to 2.88]. The indirect effect of psychosocial well-being via emotion-driven impulsiveness was 0.61 [0.24 to 1.09] for average sweet propensity and 0.55 [0.13 to 0.86] for average fat propensity. CONCLUSIONS An intervention targeting emotion-driven impulsiveness, compared to psychosocial well-being, would be marginally more effective in reducing sweet and fat propensity in adolescents.

Abstract
BACKGROUND Intravenous (IV) ketamine has emerged as a rapid and effective treatment for TRD. However, the specific neural mechanisms of ketamine's effects in humans remains unclear. Although neuroplasticity is implicated as a mechanism of action in animal models, relatively few randomized controlled trials (RCTs) in TRD patients have examined ketamine's impact on functional connectivity, a posited functional marker of neuroplasticity-particularly in the context of a mood-induction paradigm (termed miFC). METHODS 152 adults with TRD (63% female; 37% male) were randomly allocated to receive a single infusion of ketamine or saline in a 2:1 ratio. We examined changes in connectivity (from baseline to 24-h post-infusion) that differed by treatment, and whether clinical treatment response at 24-h post-infusion was uniquely related (among patients allocated to ketamine relative to saline) to (1) pre-treatment connectivity and (2) changes in connectivity. We examined both miFC and rsFC, using prefrontal cortex and limbic seed regions. We also conducted a multiverse analysis to examine findings most robust against analytic decisions. FINDINGS Across both miFC and rsFC, ketamine was associated with greater in prefrontal/limbic connectivity compared to saline, and lower baseline connectivity of limbic and prefrontal regions predicted greater treatment response in patients receiving ketamine. Greater connectivity increases in participants receiving ketamine was uniquely related to greater treatment response. In addition, certain findings were identified as being reproducible against different analytic decisions in multiverse analyses. INTERPRETATION Our findings identify specific neural connectivity patterns impacted by ketamine and were uniquely related to outcomes following ketamine (relative to saline). These findings generally support prominent neuroplasticity models of ketamine's therapeutic efficacy. These findings lay new groundwork for understanding how to enhance and optimize ketamine treatments and develop novel rapid-acting treatments for depression. FUNDING This research was supported by NIH grant R01MH113857 and by the Clinical and Translational Sciences Institute at the University of Pittsburgh (UL1-TR-001857).

Abstract
Conducting research with human subjects can be difficult because of limited sample sizes and small empirical effects. We demonstrate that this problem can yield patterns of results that are practically indistinguishable from flipping a coin to determine the direction of treatment effects. We use this idea of random conclusions to establish a baseline for interpreting effect-size estimates, in turn producing more stringent thresholds for hypothesis testing and for statistical-power calculations. An examination of recent meta-analyses in psychology, neuroscience, and medicine confirms that, even if all considered effects are real, results involving small effects are indeed indistinguishable from random conclusions.

Abstract
Although the effect of media violence on aggression has garnered major attention, little is known about the link between bullying-related media exposure and bullying behaviors. Across three studies, we examined this association among Chinese adolescents. Study 1 used a large sample of adolescents (n=10,391, 51.4% boys) to investigate the link between bullying-related media exposure and bullying perpetration. Using another adolescent sample (n=3,125, 49.5% boys), Study 2 replicated the findings from Study 1 and extended the investigation from traditional bullying to cyberbullying perpetration. Study 3 examined the longitudinal associations between bullying-related media exposure and (cyber)bullying perpetration 6 months later (n = 2,744, 47.0% boys). The results suggested a positive, albeit small, association between exposure to bullying-related media and (cyber)bullying perpetration. Importantly, personal anti-bullying attitudes moderated this link, with a significant association observed among adolescents holding weak anti-bullying attitudes. Findings are discussed with respect to the media's effect on bullying behaviors.

Abstract
BACKGROUND Although many studies have examined the impact of social media use (SMU) on mental health, very few studies have examined the association of SMU with health-relevant biomarkers. OBJECTIVE Addressing this gap, we conducted a short-term longitudinal study examining the link between SMU and C-reactive protein (CRP), a biological marker of systemic inflammation predictive of major depression, chronic diseases, and mortality. METHODS We measured college students' weekly amount of SMU for 5 consecutive weeks objectively via the Screen Time app and collected blood samples at baseline and 5 weeks later. RESULTS In separate cross-sectional analyses conducted at phase 1 (baseline) and at phase 2 (5 weeks after baseline), objective SMU had a positive, concurrent association with CRP at both time points. Critically, in a longitudinal analysis, more SMU between phase 1 and phase 2 predicted increased CRP between these time points, suggesting that increased SMU led to heightened inflammation during that period. CONCLUSIONS Although more research is needed to understand why SMU led to higher inflammation, the association between objective SMU and a marker of a biological process critical to physical health presents an intriguing opportunity for future research on social media effects.

Abstract
Background Previous studies have examined the impact of greenway interventions on physical activity (PA); however, the results have been inconclusive. In order to address this issue, our study conducted a systematic review with meta-analysis to thoroughly evaluate the evidence and determine the effectiveness of greenway interventions in promoting PA. Methods We conducted a comprehensive search of literature databases, such as Web of Science, EMBASE, PubMed (via Medline), Cochrane Library, and Scopus, up to June 15, 2023. To synthesize the available evidence, we performed a meta-analysis using a random effects model. The quality of the included studies was assessed using the criteria developed by the Agency for Healthcare Research and Quality and the Newcastle-Ottawa Scale. Results A total of 9 publications were identified, involving 6, 589 individuals. The overall quality of most included studies was rated as moderate to high. Our study found that the greenway was effective in promoting PA among participants. Specifically, active travel (AT) showed a standard mean difference (SMD) of 0.10 [95% confidence interval (CI): 0.04 to 0.17], moderate-to-vigorous PA had an SMD of 0.11 (95% CI: 0.02 to 0.20), and total PA had an SMD of 0.14 (95% CI: 0.06 to 0.21). We also observed significant differences in AT levels among participants based on greenway characteristics, exposure distance, exposure duration, and male-to-female ratio. Discussion Newly developed or upgraded greenways have been shown to effectively promote PA. Additionally, research suggests that the longer a greenway has been in existence, the greater the benefits it provides for PA. As a result, the construction of greenways should be recognized as an effective public health intervention.

Abstract
This vignette-based study examined in a sample of unvaccinated Belgian citizens (N = 1918; Mage = 45.99) how health care workers could foster reflection about and intentions to get vaccinated against COVID-19 by experimentally varying their communication style (i.e., autonomy-supportive vs. controlling) and the reference to external motivators (i.e., use of a monetary voucher or corona pass vs. the lack thereof). Each participant was randomly assigned to one of six conditions and rated a vignette in terms of anticipated autonomy satisfaction, perceived effectiveness, reflection, and vaccination intention. An autonomy-supportive, relative to a controlling, communication style predicted greater autonomy need satisfaction, which in turn related positively to perceived effectiveness, reflection, and vaccination intention. External motivators failed to generate positive effects compared to the control condition. The findings highlight the critical role of autonomy support in promoting a self-endorsed decision to get vaccinated.

Abstract
One of the most fundamental questions in social psychology is whether norms can change individuals' minds by shaping the visual appearance of stimuli. This question was first raised by Muzafer Sherif (1935). Drawing on the extended social reinforcement account (Germar and Mojzisch, 2019), we aimed to provide a rigorous test of the hypothesis that norm learning leads to a persistent perceptual bias and, hence, to a change in the visual appearance of stimuli. From a methodological perspective, we used both a diffusion model approach and the method of adjustment, a well-established technique from psychophysics and vision research. The results of Experiments 1-3 show that norm effects on perceptual decision-making are robustly replicable, and are due to genuine social influence, that is, they cannot be explained by non-social priming, contingency learning effects (Experiments 1 and 2) or anchoring effects (Experiment 3). Most importantly, by using a psychophysical approach, Experiment 4 shows, for the first time, that social norm learning alters individuals' point of subjective equality and, hence, the visual appearance of stimuli.

Abstract
In this research, we examine how the lay conceptualization of subjective social class varies based on economic contexts. We argue that income should be a more central component of subjective social class in areas with higher income inequality. To address the issue of low power in existing research, we combined local-level income inequality indicators with large-scale repeated cross-sectional data, enabling the most reliable test to date on how the relationship between income and subjective social class is moderated by inequality. We used nationally representative datasets from the United States and South Korea (encompassing 25,000+ participants from 1,246 regional-year units). In both cultural contexts, our multilevel models revealed that income is a stronger predictor of subjective social class in regions with higher levels of income inequality. This work advances the theoretical and empirical understanding of how income and income inequality interact to shape the perception of one's position in the social hierarchy.

Abstract
The colonial ideologies of historical negation and symbolic exclusion (i.e., the "Dark Duo") promote inequality between settler colonizers and Indigenous peoples by denying the contemporary relevance of past injustices and excluding Indigenous culture from the nation's identity, respectively. Although their correlates are established, the temporal ordering of the relationship between the Dark Duo and bicultural policy opposition is unclear. We address this oversight by utilizing nine annual waves of panel data from a nationwide random sample of New Zealand adults (N = 31,104) to estimate two multigroup RI-CLPMs using the Dark Duo to predict symbolic and resource-based policy opposition (and vice versa). Results revealed that within-person increases in historical negation and symbolic exclusion predicted subsequent increases in symbolic and resource-based bicultural policy opposition for both majority and minority ethnic groups. These relationships were, however, bidirectional, demonstrating a self-perpetuating cycle, whereby the Dark Duo undermines biculturalism and antibiculturalism strengthens the Dark Duo.

Abstract
OBJECTIVE To develop two prediction algorithms recommending person-centered experiential therapy (PCET) or cognitive-behavioral therapy (CBT) for patients with depression: (1) a full data model using multiple trial-based and routine variables, and (2) a routine data model using only variables available in the English NHS Talking Therapies program. METHOD Data was used from the PRaCTICED trial comparing PCET vs. CBT for 255 patients meeting a diagnosis of moderate or severe depression. Separate full and routine data models were derived and the latter tested in an external data sample. RESULTS The full data model provided the better prediction, yielding a significant difference in outcome between patients receiving their optimal vs. non-optimal treatment at 6- (Cohen's d = .65 [.40, .91]) and 12 months (d = .85 [.59, 1.10]) post-randomization. The routine data model performed similarly in the training and test samples with non-significant effect sizes, d = .19 [-.05, .44] and d = .21 [-.00, .43], respectively. For patients with the strongest treatment matching (d ≥ 0.3), the resulting effect size was significant, d = .38 [.11, 64]. CONCLUSION A treatment selection algorithm might be used to recommend PCET or CBT. Although the overall effects were small, targeted matching yielded somewhat larger effects.

Abstract
In countries such as Britain and the US, court witnesses must declare they will provide truthful evidence and are often compelled to publicly choose between religious ("oath") and secular ("affirmation") versions of this declaration. Might defendants who opt to swear an oath enjoy more favourable outcomes than those who choose to affirm? Two preliminary, pre-registered survey studies using minimal vignettes (Study 1, N = 443; Study 2, N = 913) indicated that people associate choice of the oath with credible testimony; and that participants, especially religious participants, discriminate against defendants who affirm. In a third, Registered Report study (Study 3, N = 1821), we used a more elaborate audiovisual mock trial paradigm to better estimate the real-world influence of declaration choice. Participants were asked to render a verdict for a defendant who either swore or affirmed, and were themselves required to swear or affirm that they would try the defendant in good faith. Overall, the defendant was not considered guiltier when affirming rather than swearing, nor did mock-juror belief in God moderate this effect. However, jurors who themselves swore an oath did discriminate against the affirming defendant. Exploratory analyses suggest this effect may be driven by authoritarianism, perhaps because high-authoritarian jurors consider the oath the traditional (and therefore correct) declaration to choose. We discuss the real-world implications of these findings and conclude the religious oath is an antiquated legal ritual that needs reform.

Associations of psychoactive substances and steroid hormones in hair: Findings relevant to stress research from a large cohort of young adults. Psychoneuroendocrinology 2023; 157:106369. [PMID: 37639800 DOI: 10.1016/j.psyneuen.2023.106369] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 07/03/2023] [Accepted: 08/13/2023] [Indexed: 08/31/2023]
Abstract
OBJECTIVE Epidemiological studies increasingly use hair samples to assess people's cumulative exposure to steroid hormones, but how the use of different psychoactive substances may affect steroid hormone levels in hair is, so far, largely unknown. The current study addresses this gap by establishing the substance exposure correlates of cortisol, cortisone, and testosterone in hair, while also accounting for a number of relevant covariates. METHOD Data came from a large urban community-sample of young adults with a high prevalence of substance use (N = 1002, mean age=20.6 years, 50.2% female), who provided 3 cm of hair samples. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) quantified cortisol, cortisone, and testosterone, as well as delta-9-tetrahydrocannabinol (THC), 3,4-methylenedioxymethamphetamine (MDMA, "Ecstasy"), cocaine, several opioids, and their respective metabolites. Multiple linear regression models with covariates were used to predict steroid hormone levels from substance exposure in a four-step approach: In the full sample, low and high substance hair concentrations (median split) were first tested against no use for each substance individually (step 1) and for all substances together (step 2). Then, within the participants with any substance in hair only, the continuous hair concentration of each substance in pg/mg (step 3) and finally of all substances together, were regressed (step 4). RESULTS Low, high, and continuous levels of THC in hair were robustly associated with higher levels of cortisol (sig. in step 1 low THC: β = 0.29, p = .021; high THC: β = 0.42, p = .001; step 2: low THC: β = 0.27, p = 0.036, and high THC: β = 0.40, p = .004, and step 4: β = 0.12, p = .041). Participants with high MDMA levels had higher levels of cortisone without adjusting for other substances (step 1: β = 0.34, p = .026), but this effect was not significant in the other models. While high THC levels were associated with lower levels of testosterone in step 2 (β = -0.35, p = .018), MDMA concentration was positively related to testosterone concentration with and without adjusting for other substances (step 3: β = 0.24, p = .041; step 4: β = 0.17, 95%, p = .015) in male participants. CONCLUSION The use of psychoactive substances, especially of cannabis and ecstasy, should be considered in studies investigating steroid hormones in hair.

Abstract
Reporting of effect sizes is standard practice in psychology and psychiatry research. However, interpretation of these effect sizes can be meaningless or misleading - in particular, the evaluation of specific effect sizes as 'small', 'medium' and 'large' can be inaccurate depending on the research context. A real-world example of this is research into the mental health of children and young people during the COVID-19 pandemic. Evidence suggests that clinicians and services are struggling with increased demand, yet population studies looking at the difference in mental health before and during the pandemic report effect sizes that are deemed 'small'. In this short review, we utilise simulations to demonstrate that a relatively small shift in mean scores on mental health measures can indicate a large shift in the number of cases of anxiety and depression when scaled up to an entire population. This shows that 'small' effect sizes can in some contexts be large and impactful.

Abstract
BACKGROUND Given the sensitive nature of COVID-19 beliefs, evaluating them explicitly and implicitly may provide a fuller picture of how these beliefs vary based on identities and how they relate to mental health. OBJECTIVE Three novel brief implicit association tests (BIATs) were created and evaluated: two that measured COVID-19-as-dangerous (vs. safe) and one that measured COVID-19 precautions-as-necessary (vs. unnecessary). Implicit and explicit COVID-19 associations were examined based on individuals' demographic characteristics. Implicit associations were hypothesized to uniquely contribute to individuals' self-reports of mental health. METHODS Participants (N = 13,413 US residents; April-November 2020) were volunteers for a COVID-19 study. Participants completed one BIAT and self-report measures. This was a preregistered study with a planned internal replication. RESULTS Results revealed older age was weakly associated with stronger implicit and explicit associations of COVID-as-dangerous and precautions-as-necessary. Black and Asian individuals reported greater necessity of taking precautions than White individuals (with small-to-medium effects); greater education was associated with greater explicit reports of COVID-19-as-dangerous and precautions-as-necessary with small effects. Replicated relationships between COVID-as-dangerous explicit associations and mental health had very small effects. CONCLUSIONS Implicit associations did not predict mental health but there was evidence that stronger COVID-19-as-dangerous explicit associations are weakly associated with worse mental health.

Abstract
OBJECTIVE Randomized control trials (RCTs) have played a critical role in psychotherapy research. This article discusses RCTs in the context of the criteria for drawing causal inferences in psychotherapy and intervention research more generally. The article also highlights underused variations of RCTs and how they not only establish causal relations but also address critical questions that can improve our intervention portfolio and patient care. CONCLUSION Random assignment is discussed in terms of what it can and cannot do in relation to drawing conclusions about the effects of interventions. Finally, RCTs are examined in the context of multiple questions that can guide therapy research, improve patient care, and develop treatments that reach people in need of psychological services.

Abstract
Although there is consensus that the intergroup ideology of multiculturalism is negatively related to prejudice and that assimilation is positively related to prejudice, research regarding the relationship of racial colorblindness to prejudice has produced mixed results. We investigated whether these mixed results might stem from colorblindness being a multifaceted construct despite typically being treated as unidimensional. Exploratory and confirmatory factor analyses of items from existing measures revealed three factors-equality orientation, color evasion, and rejection of racial categorization-from which we created the Multidimensional Assessment of Racial Colorblindness (MARC). Four studies provided evidence for the reliability and construct validity of the MARC and found that its subscales were often differentially related to other variables, including prejudice. We also compared the MARC to another measure of colorblindness, the Color-Blind Racial Attitudes Scale (CoBRAS). We discuss the implications of racial colorblindness as a multifaceted construct.

Abstract
Research shows that discrimination is widespread in work organizations, yet we know little about the causal effects of discrimination on employees' work effort. Here we argue that, by decoupling effort from rewards, discrimination reduces the work effort of those who are disadvantaged by discrimination and those advantaged by it. We test these arguments against the results of five experiments designed to model promotion situations in organizations (total N = 1,184). Together, these studies show that when supervised by a manager with a discriminatory preference, both disadvantaged and advantaged workers reduce their work effort relative to a control condition where the manager is not discriminatory. The negative effect of discrimination is larger for those disadvantaged by it. These effects are mediated by employees' beliefs about how strongly work will impact their chances of reward. We then demonstrate that the relatively greater effort of advantaged-versus disadvantaged-workers in discriminatory organizations leads to a self-fulfilling prophecy: when faced with this effort differential, managers (N = 119) who did not have a priori discriminatory attitudes judged the advantaged category as more competent and deserving of workplace advancement than the disadvantaged category. Our results show that even though discrimination reduces all workers' effort, it can ultimately produce outcomes that reify and entrench discriminatory beliefs.

Abstract
Model-based planning is thought to protect against over-reliance on habits. It is reduced in individuals high in compulsivity, but effect sizes are small and may depend on subtle features of the tasks used to assess it. We developed a diamond-shooting smartphone game that measures model-based planning in an at-home setting, and varied the game's structure within and across participants to assess how it affects measurement reliability and validity with respect to previously established correlates of model-based planning, with a focus on compulsivity. Increasing the number of trials used to estimate model-based planning did remarkably little to affect the association with compulsivity, because the greatest signal was in earlier trials. Associations with compulsivity were higher when transition ratios were less deterministic and depending on the reward drift utilised. These findings suggest that model-based planning can be measured at home via an app, can be estimated in relatively few trials using certain design features, and can be optimised for sensitivity to compulsive symptoms in the general population.

Abstract
Social media were designed to connect people and support interpersonal relationships. However, whether social media use is linked to the connection between the self and others is unknown. The present research reviewed findings across psychology to address whether social media use is linked to defining and expressing the self as connected to others (i.e., interdependence) versus separate from others (i.e., independence) and whether this link appears in both individualistic and collectivistic cultures. Eligible studies reported an association between social media use (e.g., time spent, frequency of use) and a characteristic supportive of independence (e.g., narcissism, envy, self-enhancement). Meta-analytic results of 133 effect sizes across the reviewed studies show that social media use is linked to independence rather than interdependence. This relationship was more pronounced in collectivistic cultures than in individualistic cultures. These findings suggest that characteristics linked to social media use differ from what one might expect based on the design of social media to connect people.

Abstract
OBJECTIVE Obesity is a disorder of excessive adiposity, typically assessed via the anthropometric density measure of BMI. Numerous studies have implicated BMI with differences in brain structure, but with highly inconsistent findings. METHODS Machine learning elastic net regression models with cross-validation were conducted to characterize a neuroanatomical morphometry profile associated with BMI in 1100 participants (22% BMI > 30, n = 242) from the Human Connectome Project Young Adult project. RESULTS Using five-fold cross-validation, the multiregion neuroanatomical profile substantively predicted BMI (R2 = 10.05%), and this was robust in a held-out test set (R2 = 8.87%). In terms of specific regions, the neuroanatomical profile was enriched for nodes in the default mode, executive control, and salience networks. The relationship between the morphometry profile and BMI itself was partially mediated by impulsive delay discounting and general cognitive ability. CONCLUSIONS Taken together, these findings reveal a robust machine learning-derived neuroanatomical profile of BMI, one that comprises nodes in motivational brain networks and suggests the functional links to obesity are via self-regulatory capacity and cognitive function.
