Developing a measure of interpretation bias for depressed mood: An ambiguous scenarios test

The tendency to interpret ambiguous everyday situations in a relatively negative manner (negative interpretation bias) is central to cognitive models of depression. Limited tools are available to measure this bias, either experimentally or in the clinic. This study aimed to develop a pragmatic interpretation bias measure using an ambiguous scenarios test relevant to depressed mood (the AST-D).¹ In Study 1, after a pilot phase (N = 53), the AST-D was presented via a web-based survey (N = 208). Participants imagined and rated each AST-D ambiguous scenario. As predicted, higher dysphoric mood was associated with lower pleasantness ratings (more negative bias), independent of mental imagery measures. In Study 2, self-report ratings were compared with objective ratings of participants’ imagined outcomes of the ambiguous scenarios (N = 41). Data were collected in the experimental context of a functional Magnetic Resonance Imaging scanner. Consistent with subjective bias scores, independent judges rated more sentences as negatively valenced for the high versus low dysphoric group. Overall, results suggest the potential utility of the AST-D in assessing interpretation bias associated with depressed mood.     

The hazards of underspecified models: the case of symmetry in everyday predictions

Should one be more confident when predicting the whole (or an event based on a larger sample) from the part (or an event based on a smaller sample) than when predicting the reverse? The relevant literature on judgment under uncertainty argues that such predictions are symmetrical but that, as an empirical matter, people often fail to appreciate this symmetry. The authors show that symmetry in prediction does not necessarily hold. In addition to an empirical study involving predictions about soccer games, they develop a theoretical model showing that, at least for the ranges of numerical values usually found in everyday judgment problems, symmetry in predictions is uncommon when 2 different sample sizes are involved. The complexity of the theoretical model used in this analysis raises questions about model specification in judgmental research.     

Longitudinal links between childhood peer acceptance and the neural correlates of sharing

Childhood peer acceptance is associated with high levels of prosocial behavior and advanced perspective taking skills. Yet, the neurobiological mechanisms underlying these associations have not been studied. This functional magnetic resonance imaging study examined the neural correlates of sharing decisions in a group of adolescents who had a stable accepted status (n = 27) and a group who had a chronic rejected status (n = 19) across six elementary school grades. Both groups of adolescents played three allocation games in which they could share money with strangers with varying costs and profits to them and the other person. Stably accepted adolescents were more likely to share their money with unknown others than chronically rejected adolescents when sharing was not costly. Neuroimaging analyses showed that stably accepted adolescents, compared to chronically rejected adolescents, exhibited higher levels of activation in the temporo‐parietal junction, posterior superior temporal sulcus, temporal pole, pre‐supplementary motor area, and anterior insula during costly sharing decisions. These findings demonstrate that stable peer acceptance across childhood is associated with heightened activity in brain regions previously linked to perspective taking and the detection of social norm violations during adolescence, and thereby provide insight into processes underlying the widely established links between peer acceptance and prosocial behavior.     

Family Background and Individual Measures as Predictors of Turkish Primary School Children's Academic Achievement

The primary purpose of this study was to predict academic grade point averages (GPAs) of Turki primary school children, using family background and individual measures (sociometric standing, self-reported loneliness, and social efficacy) as predictors. We hypothesized that these two measures would explain the wide variation in GPA for samples differing with respect to sex and paternal education. Regression analyses with male and female subsamples revealed that the background measures explained twice as much variance in GPA, popularity, and loneliness for girls as for boys. Another finding was that the background measures explained a greater proportion of the variance in GPA for children with less-versus more-educated fathers, whereas individual measures explained a greater proportion of the variance for children with more as opposed to less educated fathers.     

Fairness considerations: Increasing understanding of intentionality during adolescence

The development of fairness considerations in decision making is not well understood. Here we tested the hypothesis that increased understanding of intentionality during adolescence underlies increased fairness considerations in social decision making. We conducted three experiments using an adapted version of the Ultimatum Game with participants during four stages of adolescence: 9, 12, 15, and 18 years of age. Participants made or evaluated monetary offers, and we manipulated the intentionality context of offers. Results show that strategic thinking is already present at 9 years of age. There was no age difference in fairness of offers when the responder could not reject an offer (Experiment 1), but when they could reject an offer there was an age-related increase in taking into account the perspective and intentionality of other players when making offers (Experiment 2) and evaluating offers (Experiment 3). Taken together, the results demonstrate a linear developmental transition in fairness considerations that may have important implications for our understanding of social interactions during adolescence.     

Friend versus foe: Neural correlates of prosocial decisions for liked and disliked peers

Although the majority of our social interactions are with people we know, few studies have investigated the neural correlates of sharing valuable resources with familiar others. Using an ecologically valid research paradigm, this functional magnetic resonance imaging study examined the neural correlates of prosocial and selfish behavior in interactions with real-life friends and disliked peers in young adults. Participants (N = 27) distributed coins between themselves and another person, where they could make selfish choices that maximized their own gains or prosocial choices that maximized outcomes of the other. Participants were more prosocial toward friends and more selfish toward disliked peers. Individual prosociality levels toward friends were associated negatively with supplementary motor area and anterior insula activity. Further preliminary analyses showed that prosocial decisions involving friends were associated with heightened activity in the bilateral posterior temporoparietal junction, and selfish decisions involving disliked peers were associated with heightened superior temporal sulcus activity, which are brain regions consistently shown to be involved in mentalizing and perspective taking in prior studies. Further, activation of the putamen was observed during prosocial choices involving friends and selfish choices involving disliked peers. These findings provide insights into the modulation of neural processes that underlie prosocial behavior as a function of a positive or negative relationship with the interaction partner.     

The role of culture in appraisals,emotions and helplessness in response to threats

In honour cultures, such as Turkey, reputation management is emphasised, whereas in dignity cultures such as northern US, self-respect and personal achievements are central. Turkey is also a collectivistic culture, where relationship harmony is as important as reputation management. When Turkish people's reputation is threatened, they may experience an internal conflict between these two motives and display helplessness. The purpose of the present study was to examine how people from Turkey (an honour culture; n = 52) and northern US (a dignity culture; n = 48) would perceive and respond to reputation threats as opposed to self-respect threats. As predicted, Turkish participants anticipated stronger anger, shame, and helplessness in response to reputation threats than self-respect threats, whereas differences were smaller or non-existent in northern US. Moreover, shame was a mediator between appraisal and helplessness for reputation threats in Turkey (shame positively predicted helplessness); anger was a mediator between appraisal and helplessness for self-respect threats in northern US (anger negatively predicted helplessness). These results are novel in their inclusion of helplessness and appraisal theory of emotions when examining responses to threats in honour and dignity cultures.
