Truth is its own reward: Completeness of information, the feeling of truth knowing, and victims' closure

Victims of crime often want the truth about what happened. Yet, how exactly is truth valuable? Commonly, truth is thought to be instrumentally valuable by providing useful knowledge. Truth would be beneficial for victims because specific information may afford re-appraisals or greater understanding. The present research shows that truth may have inherent value independent from information content by providing truth knowing, a subjective sense of having the complete account, which facilitates closure. In Study 1 (n = 200) and Study 2 (n = 195), participants imagined themselves as victims of crime and were presented with one of two reports identical in content but designed to appear either complete or incomplete. As predicted, the complete report increased truth knowing and not understanding. Truth knowing was associated with greater closure, reduced affect, and greater forgiveness. In Study 3 (n = 157), real crime victims responded to one of two question sets making salient either the completeness or incompleteness of the information available about the crime. Salience of the completeness of information increased truth knowing, increased closure, reduced anger, and was associated with greater forgiveness. Findings suggest that truth knowing may facilitate the recovery of victims independently from instrumental value derived from content.

Is Creative Description Always Effective in Purchase Intention? The Construal Level Theory as a Moderating Effect

Recent years has witnessed a rapid growth in online shopping. This paper draws from the construal level theory to examine the divergent effects of the creative text descriptions of products on consumers' purchase intention in an online context. It also investigates consumers' construal level and the moderating role of construal level in this relationship. An assumption has been made that the creative description embraces more rhetorical devices with analogies. In doing so, such texts are in need of consumers who are having a more abstract, top-down, flexible mindset, which makes it more persuasive to some consumers with high-level construal. Three experiments add evidence to this study. These results suggest that the creative text descriptions are generally more persuasive than the non-creative ones in an online context, and that the persuasiveness of the creative descriptions can be accentuated (vs. attenuated) especially for high- (vs. low-) level construal individuals. The findings hold various theoretical implications for the creative marketing messages and construal level theory. First, in the current research, broadening, and integrating relevant research were possible by exploring the creative language in an online context. Also, it demonstrates that construal level-that is, consumers' internal thoughts, rather than external factors-influences their preference for a creative description style, thus helping extend the applications of the construal level theory to the field of creative marketing communications and integrate the research discoveries in metaphor communication.

Small Effects: The Indispensable Foundation for a Cumulative Psychological Science

We draw on genetics research to argue that complex psychological phenomena are most likely determined by a multitude of causes and that any individual cause is likely to have only a small effect. Building on this, we highlight the dangers of a publication culture that continues to demand large effects. First, it rewards inflated effects that are unlikely to be real and encourages practices likely to yield such effects. Second, it overlooks the small effects that are most likely to be real, hindering attempts to identify and understand the actual determinants of complex psychological phenomena. We then explain the theoretical and practical relevance of small effects, which can have substantial consequences, especially when considered at scale and over time. Finally, we suggest ways in which scholars can harness these insights to advance research and practices in psychology (i.e., leveraging the power of big data, machine learning, and crowdsourcing science; promoting rigorous preregistration, including prespecifying the smallest effect size of interest; contextualizing effects; changing cultural norms to reward accurate and meaningful effects rather than exaggerated and unreliable effects). Only once small effects are accepted as the norm, rather than the exception, can a reliable and reproducible cumulative psychological science be built.

Putting Psychology to the Test: Rethinking Model Evaluation Through Benchmarking and Prediction

Consensus on standards for evaluating models and theories is an integral part of every science. Nonetheless, in psychology, relatively little focus has been placed on defining reliable communal metrics to assess model performance. Evaluation practices are often idiosyncratic and are affected by a number of shortcomings (e.g., failure to assess models' ability to generalize to unseen data) that make it difficult to discriminate between good and bad models. Drawing inspiration from fields such as machine learning and statistical genetics, we argue in favor of introducing common benchmarks as a means of overcoming the lack of reliable model evaluation criteria currently observed in psychology. We discuss a number of principles benchmarks should satisfy to achieve maximal utility, identify concrete steps the community could take to promote the development of such benchmarks, and address a number of potential pitfalls and concerns that may arise in the course of implementation. We argue that reaching consensus on common evaluation benchmarks will foster cumulative progress in psychology and encourage researchers to place heavier emphasis on the practical utility of scientific models.

Pupillary Responses to Faces Are Modulated by Familiarity and Rewarding Context

Observing familiar (known, recognisable) and socially relevant (personally important) faces elicits activation in the brain’s reward circuit. Although smiling faces are often used as social rewards in research, it is firstly unclear whether familiarity and social relevance modulate the processing of faces differently, and secondly whether this processing depends on the feedback context, i.e., if it is different when smiles are delivered depending on performance or in the absence of any action (passive viewing). In this preregistered study, we compared pupillary responses to smiling faces differing in subjective familiarity and social relevance. They were displayed in a passive viewing task and in an active task (a speeded visual short-term memory task). The pupils were affected only in the active task and only by subjective familiarity. Contrary to expectations, smaller dilations were observed in response to more familiar faces. Behavioural ratings supported the superior rewarding context of the active task, with higher reward ratings for the game than the passive task. This study offers two major insights. Firstly, familiarity plays a role in the processing of social rewards, as known and unknown faces influence the autonomic responses differently. Secondly, the feedback context is crucial in reward research as positive stimuli are rewarding when they are dependent on performance.

Were we stressed or was it just me - and does it even matter? Efforts to disentangle individual and collective resilience within real and imagined stressors

Although resilience is a multi-level process, research largely focuses on the individual and little is known about how resilience may distinctly present at the group level. Even less is known about subjective conceptualizations of resilience at either level. Therefore, two studies sought to better understand how individuals conceptualize resilience both as an individual and as a group. Study 1 (N = 123) experimentally manipulated whether participants reported on either individual or group-based responses to real stressors and analysed their qualitative responses. For individual responses, subjective resilience featured active coping most prominently, whereas social support was the focus for group-based responses. As these differences might be attributable to the different stressors people remembered in either condition, Study 2 (N = 171) held a hypothetical stressor (i.e., natural disaster) constant. As expected, resilience at the group level emphasized maintaining group cohesion. Surprisingly, the group condition also reported increased likelihood to engage in blame, denial, and behavioural disengagement. Contrary to expectations, participants in the individual condition reported stronger desire to seek out new groups. The combined findings are discussed within the framework of resilience and social identity and highlight the necessity of accounting for multiple levels and subjective conceptualizations of resilience.

Is There a "Gestalt Bias" in Indulgence? Subjectively Constructing Food Units Into Wholes (vs. Parts) Increases Desire to Eat and Actual Consumption

In the present work we extend research into the unit bias effect and its extension—the portion size effect—by demonstrating the existence of a “Gestalt bias.” Drawing on the tenets of Gestalt psychology, we show that a unit bias effect can be observed for food portions that are composed of identical basic units, but which are subjectively grouped into, or perceived as a Gestalt—a larger whole. In three studies, we find that such subjectively constructed food wholes constitute a new (perceptual) unit that is perceived bigger than the units it is constructed from, thereby prompting increased eating and desire to eat.

Denouncing the use of field-specific effect size distributions to inform magnitude

An effect size (ES) provides valuable information regarding the magnitude of effects, with the interpretation of magnitude being the most important. Interpreting ES magnitude requires combining information from the numerical ES value and the context of the research. However, many researchers adopt popular benchmarks such as those proposed by Cohen. More recently, researchers have proposed interpreting ES magnitude relative to the distribution of observed ESs in a specific field, creating unique benchmarks for declaring effects small, medium or large. However, there is no valid rationale whatsoever for this approach. This study was carried out in two parts: (1) We identified articles that proposed the use of field-specific ES distributions to interpret magnitude (primary articles); and (2) We identified articles that cited the primary articles and classified them by year and publication type. The first type consisted of methodological papers. The second type included articles that interpreted ES magnitude using the approach proposed in the primary articles. There has been a steady increase in the number of methodological and substantial articles discussing or adopting the approach of interpreting ES magnitude by considering the distribution of observed ES in that field, even though the approach is devoid of a theoretical framework. It is hoped that this research will restrict the practice of interpreting ES magnitude relative to the distribution of ES values in a field and instead encourage researchers to interpret such by considering the specific context of the study.

Improved procedures and computer programs for equivalence assessment of correlation coefficients

The correlation coefficient is the most commonly used measure for summarizing the magnitude and direction of linear relationship between two response variables. Considerable literature has been devoted to the inference procedures for significance tests and confidence intervals of correlations. However, the essential problem of evaluating correlation equivalence has not been adequately examined. For the purpose of expanding the usefulness of correlational techniques, this article focuses on the Pearson product-moment correlation coefficient and the Fisher's z transformation for developing equivalence procedures of correlation coefficients. Equivalence tests are proposed to assess whether a correlation coefficient is within a designated reference range for declaring equivalence decisions. The important aspects of Type I error rate, power calculation, and sample size determination are also considered. Special emphasis is given to clarify the nature and deficiency of the two one-sided tests for detecting a lack of association. The findings demonstrate the inappropriateness of existing methods for equivalence appraisal and validate the suggested techniques as reliable and primary tools in correlation analysis.

The role of beauty as currency belief in acceptance of cosmetic surgery and career aspirations among Chinese young women

The current study tested the "beauty as currency" hypothesis in the framework of Objectification theory with a sample of Chinese young women. Four hundred and four college women completed a pencil-and-paper questionnaire. We hypothesized that beauty as currency would be associated with acceptance of cosmetic surgery and career aspirations through the serial meditation of self-objectification and body surveillance. The results indicated that self-objectification and body surveillance mediated the relation between women's belief in beauty as currency and acceptance of cosmetic surgery. Body surveillance mediated the relationship between beauty as currency and career aspirations. These findings provide further evidence for the "beauty as currency" hypothesis, suggesting the feminine beauty ideology may lead to women's higher acceptance of cosmetic surgery and lower career aspirations via the self-objectifying process. Our study provides some implications for understanding the effect of women's ideologies on gender system change.

Technology-enacted abusive supervision and its effect on work and family

This study examines the effects of technology-enacted abusive supervision, defined as subordinate perceptions of supervisor's use of information and communication technologies (ICTs) to engage in hostile communications. This research was designed to examine if technology-enacted abusive supervision has an impact on both the work and family domains. Based on conservation of resources theory, we theorize that technology-enacted abusive supervision enhances subordinate engagement in emotional labor surface acting, which contributes to emotional exhaustion, which in turn impacts both the work and family domains. Results demonstrate significant paths in both domains. Subordinate perceptions of technology-enacted abusive supervision are positively related to the engagement in technology-enacted incivility through the serial mediation of emotional labor surface acting and emotional exhaustion. Additionally, subordinate perceptions of technology-enacted abusive supervision are positively related to family undermining at home for the subordinate through the serial mediation of emotional labor surface acting, emotional exhaustion, and stress transmission.

When sexism is not a problem: The role of perceived intelligence in willingness to interact with someone who is sexist

Two studies examined factors that would influence people's preferences for interaction with a perpetrator of sexism. In Study 1 (n = 348), participants preferred to interact (being friends or developing a relationship) with an intelligent person regardless of whether or not that person was sexist. Study 2 (n = 614) replicated this finding and confirmed that where a perpetrator had a high level of intelligence, people were more willing to interact with them, regardless of the perpetrator's sex and the perceived commission or non-commission of sexist behavior. Moreover, Study 2 provides evidence that participants' hostile sexism beliefs are a significant covariate of a willingness to interact with unintelligent women. The results are discussed in terms of their implications for the understanding of person perception.

Narcissism and Exercise Addiction: The Mediating Roles of Exercise-Related Motives

The present research examined whether the associations that narcissistic personality features had with exercise addiction were mediated by particular motives for engaging in exercise in a large Israeli community sample (N = 2629). The results revealed that each aspect of narcissism was positively associated with exercise addiction. Narcissistic admiration and narcissistic rivalry had similar positive indirect associations with exercise addiction through the interpersonal motive for exercise. However, these aspects of narcissism diverged in their indirect associations with exercise addiction through psychological motives, body-related motives, and fitness motives for exercise such that these indirect associations were positive for narcissistic admiration but negative for narcissistic rivalry. Narcissistic vulnerability had positive indirect associations with exercise addiction through body-related motives and fitness motives that were similar to those observed for narcissistic admiration. These results suggest that exercise-related motives may play important roles in the associations that narcissistic personality features have with exercise addiction. The discussion will focus on the implications of these results for understanding the complex connections between narcissism and exercise addiction.

Online betting intensity is linked with Extraversion and Conscientiousness

INTRODUCTION

Extraversion and Conscientiousness are well-studied personality traits associated with reward processing and goal prioritization, respectively, and bear on individual differences in financial risk-taking. Using unique large datasets, we investigated the link between these traits and male online gamblers' actual betting participation and intensity.

METHOD

We combined datasets containing online horse betting data (during 2015-2016) from the Finnish monopoly betting company, administrative registry data from Statistics Finland, and personality trait measures from the Finnish Defence Forces corresponding to Extraversion and Conscientiousness as defined in the five-factor model. We modelled associations between these traits and betting participation (n = 471,968) and intensity (n = 11,217) among male horse bettors (age = 36-53).

RESULTS

Controlling for demographics and IQ, individuals scoring high on Conscientiousness (or Extraversion) were less (or more) likely to bet and less (or more) intensive bettors-even when personality was measured 16-34 years before betting occurred. One SD personality score increase represented an annual decrease (Conscientiousness) or increase (Extraversion) of €570-754 in spending.

CONCLUSIONS

Extraversion and Conscientiousness are implicated in real-life financial behavior with tangible consequences for individuals. These effects are stronger than for many known demographic variables used in gambling studies and persist up to 34 years after personality has been measured.

Assessing Deception Differences with Mimicry Deception Theory

Mimicry Deception Theory (MDT) argues that deception varies along a long- to short-term continuum. Long-term deception involves complex deception, community integration, slow resource extraction, and low detectability, whereas short-term deception is the opposite. To date, no self-report scale exists that assesses a dispositional orientation toward long-term deception. Across four studies, we developed and validated a Mimicry Deception Scale (MDS) to assess individuals' dispositional orientation toward long-term deception. Using theoretically driven items, we found a reliable four-factor structure through exploratory and confirmatory factor analyses. Further, MDS components were strongly correlated and had acceptable internal consistency. For convergent validity, long-term MDS positively correlated with Machiavellianism, conscientiousness, and planning. Finally, the test-retest reliability of the MDS was acceptable, and the complexity facet of the MDS predicted successful lying over time. The findings have implications for how to profile, identify, and recognize patterns of deception, especially with respect to long-term patterns using self-report.

How pills undermine skills: Moralization of cognitive enhancement and causal selection

Despite the promise to boost human potential and wellbeing, enhancement drugs face recurring ethical scrutiny. The present studies examined attitudes toward cognitive enhancement in order to learn more about these ethical concerns, who has them, and the circumstances in which they arise. Fairness-based concerns underlay opposition to competitive use-even though enhancement drugs were described as legal, accessible and affordable. Moral values also influenced how subsequent rewards were causally explained: Opposition to competitive use reduced the causal contribution of the enhanced winner's skill, particularly among fairness-minded individuals. In a follow-up study, we asked: Would the normalization of enhancement practices alleviate concerns about their unfairness? Indeed, proliferation of competitive cognitive enhancement eradicated fairness-based concerns, and boosted the perceived causal role of the winner's skill. In contrast, purity-based concerns emerged in both recreational and competitive contexts, and were not assuaged by normalization.

Attributions to Discrimination Against Black Victims in a Multiracial Society: Isolating the Effect of Perpetrator Group Membership

As the United States becomes more racially and ethnically diverse, interactions between Black people and other minority groups have become increasingly common. The present research examined how a perpetrator's group membership affects judgments of employment discrimination against a Black victim. Four experiments (combined N = 1,016) tested predictions derived from the prototype model of discrimination. Participants reviewed a case file where a Black, Latino, Asian, or White manager rejected a Black job applicant. Attributions to discrimination were much stronger for a Latino, Asian, or White manager compared with a Black manager. Attributions to discrimination were slightly stronger for a White manager compared with an Asian or Latino manager; however, effect sizes for these differences were small. Attributions to discrimination were similar for the Asian and Latino managers. Whether the perpetrator had outgroup standing relative to the victim was the strongest factor influencing attributions to discrimination for a Black victim of employment discrimination.

Attachment styles, negotiation of goal conflict, and perceived partner support during COVID-19

Due to the pandemic, people have been stuck indoors with their partners for months. Instead of being able to rely on multiple sources of support, many couples have to rely on each other more. We investigated whether goal conflict, successful negotiation of the conflict, and individual differences in attachment styles were associated with perceived partner support to understand factors that may enable or hinder goal pursuit during the pandemic. Participants (n = 200) completed a daily diary for a week and weekly longitudinal reports for five weeks. Results showed that higher goal conflict predicted perception of less relational catalyst (RC) support and more anti-RC support from partner, whereas more successful negotiation of goal conflict predicted higher RC support and lower anti-RC support. Attachment avoidance was directly associated with less support whereas attachment anxiety moderated the relationship between goal conflict and support. Implications for partner support during the pandemic are discussed.

Moralization of Covid-19 health response: Asymmetry in tolerance for human costs

We hypothesized that because Covid-19 (C19) remains an urgent and visible threat, efforts to combat its negative health consequences have become moralized. This moralization of health-based efforts may generate asymmetries in judgement, whereby harmful by-products of those efforts (i.e., instrumental harm) are perceived as more acceptable than harm resulting from non-C19 efforts, such as prioritizing the economy or non-C19 issues. We tested our predictions in two experimental studies. In Study 1, American participants evaluated the same costs (public shaming, deaths and illnesses, and police abuse of power) as more acceptable when they resulted from efforts to minimize C19's health impacts, than when they resulted from non-health C19 efforts (e.g., prioritizing economic costs) or efforts unrelated to C19 (e.g., reducing traffic deaths). In Study 2, New Zealand participants less favorably evaluated the quality of a research proposal empirically questioning continuing a C19 elimination strategy in NZ than one questioning abandoning an elimination strategy, although both proposals contained the same amount of methodology information. This finding suggests questioning elimination approaches is morally condemned, a similar response to that found when sacred values are questioned. In both studies, condition effects were mediated by lowered moral outrage in response to costs resulting from pursuing health-minded C19 efforts. Follow-up analyses revealed that both heightened personal concern over contracting C19 and liberal ideology were associated with greater asymmetries in human cost evaluation. Altogether, results suggest efforts to reduce or eliminate C19 have become moralized, generating asymmetries in evaluations of human suffering.

Validation of Morality as Cooperation Questionnaire in Turkey, and Its Relation to Prosociality, Ideology, and Resource Scarcity

Abstract. The theory of morality as cooperation (MAC) argues that there are seven distinct and evolved universal moral foundations. Curry, Chesters, and Van Lissa (2019) developed a scale to test this theoretical approach and showed that the Relevance subscale of the MAC questionnaire (MAC-Q) fits data well, unlike the Judgment and full-form. However, an independent test of the validity of this questionnaire has not been hitherto conducted, and its relation with ideology is unknown. In the first study, we attempted to validate the Turkish form of MAC-Q and then examined the relationship with prosociality and political ideology. The results showed that the fit indices of MAC-Q Relevance are above the standard criteria, unlike the Judgment and full form ( n = 445), and significant relationships with prosociality and political ideology provided additional evidence for the validity. We used the MAC-Q Relevance in Study 2 ( n = 576, Turkey) and Study 3 ( n = 921, US), and investigated whether manipulating resource scarcity influences the endorsement of MAC. Although there was no effect of the manipulation, correlational findings provided some support for the predictive validity of MAC-Q. Overall, MAC-Q Relevance performs well in representing the lay notions of morality in both Turkey and the US, unlike full-form.

Heterogeneity of Research Results: A New Perspective From Which to Assess and Promote Progress in Psychological Science

Heterogeneity emerges when multiple close or conceptual replications on the same subject produce results that vary more than expected from the sampling error. Here we argue that unexplained heterogeneity reflects a lack of coherence between the concepts applied and data observed and therefore a lack of understanding of the subject matter. Typical levels of heterogeneity thus offer a useful but neglected perspective on the levels of understanding achieved in psychological science. Focusing on continuous outcome variables, we surveyed heterogeneity in 150 meta-analyses from cognitive, organizational, and social psychology and 57 multiple close replications. Heterogeneity proved to be very high in meta-analyses, with powerful moderators being conspicuously absent. Population effects in the average meta-analysis vary from small to very large for reasons that are typically not understood. In contrast, heterogeneity was moderate in close replications. A newly identified relationship between heterogeneity and effect size allowed us to make predictions about expected heterogeneity levels. We discuss important implications for the formulation and evaluation of theories in psychology. On the basis of insights from the history and philosophy of science, we argue that the reduction of heterogeneity is important for progress in psychology and its practical applications, and we suggest changes to our collective research practice toward this end.

p-Curve analysis of the Taylor Aggression Paradigm: Estimating evidentiary value and statistical power across 50 years of research

The overall reliability or evidentiary value of any body of literature is established in part by ruling out publication bias for any observed effects. Questionable research practices have potentially undermined the evidentiary value of commonly used research paradigms in psychological science. Subsequently, the evidentiary value of these common methodologies remains uncertain. To quantify the severity of these issues in the literature, we selected the Taylor Aggression Paradigm (TAP) as a case study and submitted 170 hypothesis tests spanning over 50 years of research to a preregistered p-curve analysis. The TAP literature (N = 24,685) demonstrated significant evidentiary value but yielded a small average effect size (d = 0.29) and inadequate power (38%). The main effects demonstrated greater evidentiary value, power, and effect sizes than interactions. Studies that tested the effects of measured traits did not differ in evidentiary value or power to those that tested the effects of experimentally manipulated states. Exploratory analyses revealed that evidentiary value, statistical power, and effect sizes have improved over time. We provide recommendations for researchers who seek to maximize the evidentiary value of their psychological measures.

Partner support and goal outcomes during COVID-19: A mixed methods study

During the COVID-19 pandemic, people have been stuck indoors with their partners for months. Having a supportive partner is likely to be especially important during this time when access to outside sources of support is limited. The present mixed-methods study aimed to investigate how partner support is associated with goal outcomes during COVID-19. The survey participants (n = 200) completed a daily diary for a week and five weekly longitudinal reports, and 48 participants attended a semi-structured interview. The quantitative results showed that higher relational catalyst support (i.e., support for growth opportunities) predicted better goal outcomes; qualitative analyses revealed partners use direct and indirect forms of emotional and instrumental support toward goal pursuit. This is important because most studies to date have not differentiated between direct and indirect forms of support. Overall, the findings suggest that having a supportive partner is important for not only surviving, but also thriving through the pandemic.

Psychological entitlement predicts noncompliance with the health guidelines of the COVID-19 pandemic

In this research, we examined whether psychological entitlement predicted noncompliance with the health guidelines of the COVID-19 pandemic. People higher in psychological entitlement typically try to avoid behaviors that might cause themselves harm, but their high expectations, lack of concern about others, and distrust of authority figures could affect their perceptions of the threat of the coronavirus and their views on the benefits of following the health guidelines. Across three studies (N = 1004, online samples from the United States), people higher in psychological entitlement reported less compliance with the health guidelines of the COVID-19 pandemic than people lower in psychological entitlement. Moreover, people higher in psychological entitlement believed that the threat of the virus was overblown and were less concerned about harming others, views that may partly explain their noncompliance. People higher in psychological entitlement were also more likely to report that they had contracted COVID-19, and thus their refusal to follow the health guidelines may have had negative consequences for them. An appeal to self-image concerns did not lead individuals higher in entitlement to be more likely to comply with the health guidelines.

The relationship between serious leisure and recreation specialization in sportspeople with and without physical disabilities

This study analyzes whether the relationship between serious leisure and recreation specialization differs for federated sportspeople with and without physical disabilities. Sportspeople with and without physical disabilities in the Basque Country (Spain) (n = 370) completed a questionnaire assessing the component dimensions of two constructs, “serious leisure” and “recreation specialization”. The Serious Leisure Inventory and Measure (SLIM) and the Recreation Specialization Index (RSI) were used in the analysis. Results showed an association between these concepts in competitive sports in both samples. However, the magnitudes of association between the total of both concepts were higher in the group with physical disabilities. Regarding perceptions about their sports practice, the group without physical disabilities showed higher levels of specialization but there were no substantial differences between their levels of serious leisure participation. In conclusion, seriousness and specialization were found to be key issues for sportspeople's practice of leisure, regardless of their physical condition.

“We Shall Overcome”: First-Person Plural Pronouns From Search Volume Data Predict Protest Mobilization Across the United States

Collective action is a key driver of social and political change within societies. So far, the main factor mobilizing individuals into collective action remains the extent to which they feel identified with a protesting group (i.e., social identification). Although the link between social identification and collective action is well-established, current evidence relies mostly on self-report data. To tackle this issue, we combined real-life protest counts in the United States (2017–2020) with online search data (Google Trends) for pronouns indicating a “group” mind-set (first-person plural pronouns; e.g., “we,” “us”). Time series analyses indicated that weekly fluctuations in searches ( N = 164) predict both protest and protester counts over time. Confirmatory mixed models then showed that a 1% increase in pronoun searches was linked with +13.67% protests (95% CI [4.02, 23.32]) and +47.45% protesters (95% CI [26.54, 68.36]) the following week. These original results have important implications for the ecological study and quantification of collective action dynamics in psychology.

Thirdhand smoke beliefs and behaviors among families of primary school children in Shanghai

INTRODUCTION

There are few reports on the beliefs about thirdhand smoke in Chinese families with primary school children. This study aims to understand the beliefs about thirdhand smoke among parents or grandparents of primary school children in Shanghai and to provide an evidence base to incorporate thirdhand smoke preventative action into tobacco control interventions.

METHODS

We performed a cross-sectional survey among parents and grandparents of children aged 6–13 years in the Changjiang Road Primary School and recruited 843 participants to make assessments on the ‘beliefs about thirdhand smoke’ (BATHS) scale. Sociodemographic details including age, gender, marital status, education level, personal income and type of home ownership (new house, secondhand house with or without redecoration) and health status of children (whether they suffered from respiratory diseases or not) were investigated. Scale assessment, univariate and multivariate analyses to explore the factors influencing the BATHS scale and subscale scores, were performed using SPSS version 22.0.

RESULTS

Participants who were aged >65 years were more likely to get lower scores on the BATHS scale (OR=0.476; 95% CI: 0.311–0.728, p=0.001). Undergraduates (OR=1.190; 95% CI: 1.020–1.388, p=0.027) and graduates (OR=1.4490; 95% CI: 1.102–1.906, p=0.008) obtained higher scores. Moreover, the scores of residents living in a secondhand house with redecoration (OR=0.882; 95% CI: 0.782–0.995, p=0.041) and without redecoration (OR=0.801; 95% CI: 0.698–0.919, p=0.002) were lower compared with those of new-house owners. The scores for participants whose children suffered from respiratory diseases in the past six months (OR=1.104; 95% CI: 1.003–1.216, p=0.043) were higher than those whose children had no respiratory diseases.

CONCLUSIONS

This study shows that younger people, females, those with higher incomes, and higher education levels, were more likely to believe the thirdhand smoke impacts on health and its persistence in the environment. Our findings can guide targeted actions for smoke-free home interventions.

A Meta-analysis on Children’s Trust in Social Robots

Although research on children’s trust in social robots is increasingly growing in popularity, a systematic understanding of the factors which influence children’s trust in robots is lacking. In addition, meta-analyses in child–robot-interaction (cHRI) have yet to be popularly adopted as a method for synthesising results. We therefore conducted a meta-analysis aimed at identifying factors influencing children’s trust in robots. We constructed four meta-analytic models based on 20 identified studies, drawn from an initial pool of 414 papers, as a means of investigating the effect of robot embodiment and behaviour on both social and competency trust. Children’s pro-social attitudes towards social robots were also explored. There was tentative evidence to suggest that more human-like attributes lead to less competency trust in robots. In addition, we found a trend towards the type of measure that was used (subjective or objective) influencing the direction of effects for social trust. The meta-analysis also revealed a tendency towards under-powered designs, as well as variation in the methods and measures used to define trust. Nonetheless, we demonstrate that it is still possible to perform rigorous analyses despite these challenges. We also provide concrete methodological recommendations for future research, such as simplifying experimental designs, conducting a priori power analyses and clearer statistical reporting.

Conditional Love: Threat and Attitudinal Perceptions of Immigrants Depend on Their Instrumentality to Locals' Basic Psychological Needs

Although threat perceptions are commonly used to explain attitudes toward immigrants, the psychological factors underlying threat are surprisingly understudied. Drawing from goal pursuit and self-determination theory, we examined the perceived instrumentality of immigrants as an antecedent of locals' threat and attitudinal perceptions. Through four studies (N = 1,372) with different configurations of local population segments and target immigrant groups, we investigated the impact of immigrants' instrumentality in terms of hindrances to locals' autonomy, belonging, and competence needs. Including hindrances to our proposed model of threats and attitudes led to an improvement in the overall fit with the data, allowed for a better specification of the threats-to-attitudes pathways, and elucidated the complexity and downstream consequences (endorsement of pro-immigration policies) of attitudes. The present findings underscore the utility of goal-driven approaches to studying intergroup conflicts, and implications for understanding and improving locals' attitudes toward immigrants are discussed.

Adults' responses to infant faces: Neutral infant facial expressions elicit the strongest baby schema effect

The effect of the babyface schema includes three typical responses, namely, the preference response, viewing motivation, and attention bias towards infant faces. It has been theorised that these responses are primarily influenced by infants' facial structures. However, recent studies have revealed the moderating role of facial expression, suggesting that the strongest effect of the babyface schema may be related to the neutral facial expression; this hypothesis remains to be tested. In this study, the moderating role of facial expression was assessed in three successive experiments (total N = 402). We used a series of images of the same face with multiple expression-standardised images of infants and adults to control for facial structure. The results indicated that the effect sizes of the babyface schema (i.e., response differences between infants and adults) were different for multiple expressions of the same face. Specifically, the effect sizes of neutral faces were significantly greater than those of happy and sad faces according to the preference response (experiment 1, N = 90), viewing motivation (experiment 2, N = 214), and attentional bias (experiment 3, N = 98). These results empirically confirm that neutral infant facial expressions elicit the strongest effect of the babyface schema under the condition of using adult faces as a comparison baseline and matching multiple expressions of the same face.
