Perceived collective continuity and ingroup identification as defence against death awareness

Perhaps unique among the animal species, humans are aware that they will ultimately die. Terror management theory (TMT) posits that investing in a social group helps people to manage paralysing anxiety stemming from death awareness. In line with this proposition, research to date has shown that when reminded of their own mortality, people increase their identification with a relevant group and defend its beliefs, values, and practices. In the reported study, we demonstrate that a mortality salience induction enhances people’s perceptions of group temporal endurance—or perceived collective continuity (PCC), as we define it. Enhanced PCC leads, in turn, to enhanced group identification. This is in line with the TMT assumption that death awareness leads people to invest in a social group because this constitutes a temporally enduring meaning-system that imbues life with meaning, order, and permanence, and promises death transcendence to those who meet the prescribed standards of value.     

Situational affect and temperament: Implications for sibling caregiving

The caregiving behaviour of 60 preschool‐age children (M=50 months) toward their 16‐month‐old younger siblings was observed during a brief separation from their parents. Sibling caregiving was more strongly associated with parent ratings of both the older siblings' and toddlers' temperament than with the younger siblings' distress exhibited during the separation. The older siblings' social fear was positively related to providing care, whereas their temperamental activity level was negatively related to caregiving. Younger siblings' temperamental anger and soothability were positively associated with receiving care from an older sibling. Relations with temperament were independent of both children's distress levels during the separation, and in several instances, dispositional affective measures (i.e. temperament) made stronger contributions to the prediction of sibling caregiving than did situational distress.

Gratitude in buyer-seller relationships: a dyadic investigation

In addressing the call for research to understand affect in sales, this research uses moral affect theory and literature on emotional contagion to examine the effects of salesperson gratitude and customer gratitude on downstream relationship outcomes. The findings of this work suggest that salesperson prosocial behaviors account for the positive association between salesperson gratitude and customer gratitude. These prosocial behaviors – information sharing and extra-role behaviors – combined with customer gratitude serve as explanatory mechanisms for the positive effects of salesperson gratitude on customer commitment, which is an important result of buyer-seller interactions and an essential component of long-term relationships. Further, this research finds that salesperson extra-role behaviors and relationship length interact such that salesperson extra-role behaviors cultivate customer gratitude within developing and established relationships, but that these behaviors are particularly beneficial for less mature relationships. Understanding the role of salesperson gratitude and customer gratitude in driving relational outcomes contributes to both a theoretical understanding of the role of affect in sales and practical applications of emotions within buyer-seller relationships.     

Improving Intergroup Relations with Extended Contact among Young Children: Mediation by Intergroup Empathy and Moderation by Direct Intergroup Contact

A correlational study investigated extended contact as a strategy to improve outgroup attitudes and stereotyping and to prepare children for future contact. Additional aims were to investigate when and why the effects of extended contact occur. In particular, intergroup empathy was tested as a mediator and direct contact (i.e. cross‐group friendship) as a moderator of extended contact. Participants were Italian and immigrant elementary school children. Results showed that extended contact was associated with improved intergroup empathy, which, in turn, was associated with more positive outgroup attitudes, stereotypes and behavioural intentions. These effects were significant only among participants with a low or moderate level of direct contact. The theoretical and practical implications of findings are discussed.

The greatest magic of Harry Potter: Reducing prejudice

Recent research shows that extended contact via story reading is a powerful strategy to improve out‐group attitudes. We conducted three studies to test whether extended contact through reading the popular best‐selling books of Harry Potter improves attitudes toward stigmatized groups (immigrants, homosexuals, refugees). Results from one experimental intervention with elementary school children and from two cross‐sectional studies with high school and university students (in Italy and United Kingdom) supported our main hypothesis. Identification with the main character (i.e., Harry Potter) and disidentification from the negative character (i.e., Voldemort) moderated the effect. Perspective taking emerged as the process allowing attitude improvement. Theoretical and practical implications of the findings are discussed in the context of extended intergroup contact and social cognitive theory.     

Bayesian inference for psychology,part III: Parameter estimation in nonstandard models

We demonstrate the use of three popular Bayesian software packages that enable researchers to estimate parameters in a broad class of models that are commonly used in psychological research. We focus on WinBUGS, JAGS, and Stan, and show how they can be interfaced from R and MATLAB. We illustrate the use of the packages through two fully worked examples; the examples involve a simple univariate linear regression and fitting a multinomial processing tree model to data from a classic false-memory experiment. We conclude with a comparison of the strengths and weaknesses of the packages. Our example code, data, and this text are available via https://osf.io/ucmaz/.     

Outcome evaluation in brief mother-infant psychotherapies: Report on 75 cases

The effects of brief mother–infant psychotherapies (maximum of 10 sessions) were examined in cases of functional and behavioral disturbances in children less than 30 months old. Seventy-five mother-infant dyads were assessed prior to treatment, at 1 week, and 6 months after therapy ended. The outcome measures were changes in the infant's symptoms, the behavioral interactions between mother and infant, and maternal representations. The effect of two forms of intervention—Psychodynamic Therapy and Interaction Guidance Therapy—were compared. Results indicated a significant symptom reduction; dyadic interactions became more harmonious (mothers became less intrusive and infants more cooperative). Maternal self-esteem grew significantly and negative affects decreased. Improvements lasted as least several months, with some positive improvement detected at the 6-month follow-up. No major difference in outcome was found between the effects of the two forms of intervention. Within the limitations of research in a clinical context, this study suggests that brief mother–infant psychotherapies are a cost-effective method of early intervention.
