Contribution of parents' adult attachment and separation attitudes to parent‐adolescent conflict resolution

This study examined the contribution to parent‐adolescent conflict resolution of parental adult attachment styles and attitudes toward adolescent separation. Questionnaires were completed by 295 couples with early to late adolescent children. Structural equation models were used to test self and partner influences on conflict resolution for three attachment orientations: confidence (model A), anxiety (model B) and avoidance (model C). Model A showed self influences between parents' confidence orientation and negotiation and also via positive attitudes towards separation. Also, the fathers' use of negotiation was facilitated by the mothers' confidence orientation and vice versa, indicating partner influences as well. Model B showed self influences between parents' anxiety orientation and the use of dominance and withdrawal and also via negative attitudes towards separation. Model C showed self influences between parents' avoidance orientation and dominance and withdrawal, and a partner influence between fathers' avoidance and mothers' use of dominance. The results indicated that the parents' adult attachment system and the parenting system were related in the area of conflict resolution, and that self influences were stronger than partner influences.     

Examining a negative halo effect to anabolic steroids users through perceived achievement goals,sportspersonship orientations,and aggressive tendencies

We investigated the social image of anabolic steroids (AS) users grounding our analysis on the achievement goal theory of Nicholls. Our main goal was to explore how an athlete’s acceptance of AS use would impact on the way that athlete will be perceived by others. Non‐AS‐using participants reacted to one of two scenarios portraying a male athlete either accepting or refusing to engage in drug use behavior. The results suggested that the acceptance of anabolic steroids yielded an unfavorable social image – perceivers inferred a predominant ego orientation to characterize the AS‐user’s motivation as well as weaker sportspersonship and a stronger proclivity for reactive aggression than instrumental aggression. Moreover, the analyses did not yield significant gender or interaction effects. Finally, those findings are commented in view of methodological shortcomings and of the perspectives that they may offer for future research concerning the motivational aspects of the social perceptions of drug use in sport.     

Bottled memories: On how alcohol affects eyewitness recall

This study investigated how different doses of alcohol affected eyewitness recall. Participants (N = 126) were randomly assigned to three groups with different blood alcohol concentration (BAC), either a control group (mean BAC 0.00%, N = 42), a lower alcohol dose group (mean BAC 0.04%, N = 40), or a higher alcohol dose group (mean BAC 0.06%, N = 44). After consumption, participants witnessed a movie of a mock crime and were interviewed one week later. The main results showed that witnesses with the higher intoxication level recalled fewer details compared to witnesses with the lower intoxication level. The amount of alcohol consumed did not have an impact on the accuracy rate. No sex differences were found. The results are discussed in the light of past research. We conclude that more studies are needed before recommendations can be made to an applied setting.     

Retribution and forgiveness: The healing effects of punishing for just deserts

Although punishment and forgiveness frequently are considered to be opposites, in the present paper we propose that victims who punish their offender are subsequently more likely to forgive. Notably, punishment means that victims get justice (i.e. just deserts), which facilitates forgiveness. Study 1 reveals that participants were more likely to forgive a friend's negligence after being primed with punishment than after being primed with inability to punish. In Study 2, participants were more forgiving towards a criminal offender if the offender was punished by a judge than if the offender escaped punishment, a finding that was mediated by the just deserts motive. Study 3 was in the context of actual recalled ongoing interpersonal relations and revealed that punishment predicted forgiveness indirectly via just deserts, not via victims' vengeful motivations. It is concluded that punishment facilitates forgiveness because of its capacity to restore a sense of justice. Copyright © 2013 John Wiley & Sons, Ltd.     

Personal values and prosocial behaviour in strategic interactions: Distinguishing value‐expressive from value‐ambivalent behaviours

Relying on the framework provided by Schwartz's theory of personal values, we investigated whether values can help explain prosocial behaviour. We first distinguished value‐expressive behaviours from value‐ambivalent behaviours. The former are compatible with primarily one value or with congruent values, the latter with mutually conflicting values. In Study 1, an analysis over all 41 (39 unpublished) samples in which we measured personal values and prosocial behaviour in monetarily incentivized strategic interactions (N = 1289; data collected between 2007 and 2010 in China, Finland, Germany, Israel, and the West Bank) supported our idea that personal values, universalism in particular, predict value‐expressive (prisoner's dilemma cooperation and trust game back‐transfers) but not value‐ambivalent behaviours (trust game transfers and ultimatum game proposals and responses). Study 2 (N = 56) focused on dictator game behaviours, which we expected and found to be strongly value‐expressive. The findings contribute to the ongoing discussion on whether and under which circumstances values shape behaviour. Copyright © 2013 John Wiley & Sons, Ltd.     

Major memory for microblogs

Online social networking is vastly popular and permits its members to post their thoughts as microblogs, an opportunity that people exploit, on Facebook alone, over 30 million times an hour. Such trivial ephemera, one might think, should vanish quickly from memory; conversely, they may comprise the sort of information that our memories are tuned to recognize, if that which we readily generate, we also readily store. In the first two experiments, participants’ memory for Facebook posts was found to be strikingly stronger than their memory for human faces or sentences from books—a magnitude comparable to the difference in memory strength between amnesics and healthy controls. The second experiment suggested that this difference is not due to Facebook posts spontaneously generating social elaboration, because memory for posts is enhanced as much by adding social elaboration as is memory for book sentences. Our final experiment, using headlines, sentences, and reader comments from articles, suggested that the remarkable memory for microblogs is also not due to their completeness or simply their topic, but may be a more general phenomenon of their being the largely spontaneous and natural emanations of the human mind.     

Learning time-varying categories

Many kinds of objects and events in our world have a strongly time-dependent quality. However, most theories about concepts and categories either are insensitive to variation over time or treat it as a nuisance factor that produces irrational order effects during learning. In this article, we present two category learning experiments in which we explored peoples’ ability to learn categories whose structure is strongly time-dependent. We suggest that order effects in categorization may in part reflect a sensitivity to changing environments, and that understanding dynamically changing concepts is an important part of developing a full account of human categorization.     

Maternal Psychopathology and Early Child Temperament Predict Young Children’s Salivary Cortisol 3 Years Later

Neuroendocrine dysfunction is hypothesized to be an early emerging vulnerability marker for depression. We tested whether the main and interactive effects of maternal psychopathology and early child temperamental vulnerability for depression assessed at age three predicted offspring’s basal cortisol function at age 6 years. 228 (122 males) children participated in the baseline and follow-up assessments. At age three, maternal lifetime psychopathology was assessed with a diagnostic clinical interview, and child temperamental positive affectivity (PA) and negative affectivity (NA) were assessed using laboratory observations. At age six, children’s waking and evening cortisol were assessed on 2 days. Maternal lifetime anxiety predicted offspring’s higher morning cortisol at age six. Child temperamental NA at age three predicted higher evening cortisol at age six. There was a significant interaction between maternal lifetime depression and child temperamental PA at age three in predicting offspring’s morning cortisol at age six. For the offspring of mothers with lifetime depression, higher PA at age 3 predicted lower morning cortisol at age 6. These findings highlight the importance of examining the main and interactive effects of maternal psychopathology and early child temperamental vulnerability in predicting the development of offspring’s stress physiology. Findings hold significance in identifying etiological mechanisms of risk and delineating the complex developmental pathways to psychopathology.
