Synchronized behavior results in a variety of prosocial behaviors. Research has also implicated that interpersonal synchrony affects pain thresholds, inferred as indicative of endorphin levels. The current study was designed to see if these pain threshold effects mediated the effect of synchrony on interpersonal cooperation. Twenty six individuals were randomly assigned to complete a 30 minute run on a treadmill in either a synchronized or nonsynchronized condition. Pain threshold was measured both before and after exercise as an indicator of endorphin activity. A postrun social investment game measured interpersonal cooperation. Analyses showed that there was a significant direct relationship between condition and cooperation but that this effect was not mediated by pain threshold.  相似文献

Human culture relies on extensive use of social transmission, which must be integrated with independently acquired (i.e. asocial) information for effective decision‐making. Formal evolutionary theory predicts that natural selection should favor adaptive learning strategies, including a bias to copy when uncertain, and a bias to disproportionately copy the majority (known as ‘conformist transmission’). Although the function and causation of these evolved strategies has been comparatively well studied, little is known of their development. We experimentally investigated the development of the bias to copy‐when‐uncertain and conformist transmission in children from the ages of 3 to 7, testing predictions derived from theoretical models. Children first attempted to solve a binary‐choice quantity discrimination task themselves using asocial information, but were then given the decisions of informants, and an opportunity to revise their answer. We investigated whether children's revised judgments were adaptively contingent on (i) the difficulty of the trial and (ii) the degree of consensus amongst informants. As predicted, older but not younger children copied others more on more difficult trials than on easier trials, even though older children also showed a tendency to stick with their initial, asocial decision. We also found that older children, like adults, were disproportionately receptive to non‐total majorities (i.e. were conformist) whereas younger children were receptive only to total (i.e. unanimous) majorities. We conclude that, whilst the mechanism for incorporating social information into decision‐making is initially very blunt, across the course of early childhood it converges on the adaptive learning mechanisms observed in adults and predicted by cultural evolutionary theory.

Severity of depressive symptoms, hopelessness, and suicidal ideation were examined to determine whether they were significantly associated with the accuracy of suicidal adolescents' ratings of stressful life events. The sample included 130 inpatient adolescents who endorsed suicide‐related behaviors. Stress interviews were administered, and the severity of stressful events was rated separately by adolescents and an independent team. A residualized cognitive bias score was created by regressing adolescents' severity ratings to the independent team's severity ratings of the same events. Depressive symptoms, but not hopelessness or suicidal ideation, were significantly associated with cognitive bias scores. A negative cognitive bias in adolescents' reports of life stress may be present at higher levels of depression relative to minimal levels of depression. Further research on the relations between stress and suicide‐related behaviors is encouraged to include independent ratings of stress severity.  相似文献

Previous meta-analyses support a female advantage in decoding non-verbal emotion (Hall, 1978, 1984), yet the mechanisms underlying this advantage are not understood. The present study examined whether the female advantage is related to greater female attention to the eyes. Eye-tracking techniques were used to measure attention to the eyes in 19 males and 20 females during a facial expression recognition task. Women were faster and more accurate in their expression recognition compared with men, and women looked more at the eyes than men. Positive relationships were observed between dwell time and number of fixations to the eyes and both accuracy of facial expression recognition and speed of facial expression recognition. These results support the hypothesis that the female advantage in facial expression recognition is related to greater female attention to the eyes.  相似文献

This article reviews the articles on career counselling in the special edition of the Journal of Psychology in Africa. A thematic analysis to the content of the articles was conducted and common themes extrapolated. The main themes were (a) the shift toward postmodern career counselling, (b) the importance of cultural sensitivity in career counselling practice and (c) adolescents career development. This is followed by a reaction comment.  相似文献

Despite efforts to understand the antecedents, correlates, and consequences of posttraumatic growth (PTG), the role of time since a traumatic event (time since event) vis-à-vis PTG is not well understood. Part of a larger project exploring experiences following emotionally distressing events among military veterans (N = 197) using Amazon’s Mechanical Turk (Mturk), in the current study, we sought to clarify associations between the time since event and PTG. We used cluster-analytic techniques and analyses of variance to (a) determine the number of clusters, and (b) assess differences in core constructs of PTG and participant characteristics across clusters. Results revealed 4 significantly different groups (i.e., clusters) characterized by differential associations between PTG and time since event. These groups also differed significantly in challenge to core beliefs, level of PTSD symptoms, intrusive and deliberate rumination, and age. The immediate moderate-growth group (Cluster 1) experienced moderate levels of PTG over shorter periods of time, severe PTSD symptoms, and was significantly younger. The low-growth group (Cluster 2) was characterized by minimal PTG, regardless of time, the least challenge to core beliefs, and low amounts of intrusive and deliberate rumination. The long-term small-growth group (Cluster 3) was primarily characterized by small amounts of PTG over longer periods of time. The high-growth group (Cluster 4) was characterized by high PTG, regardless of time, greater challenge to core beliefs, the highest amount of deliberate rumination, and the highest number of PTSD symptoms. Findings underscore heterogeneity within military veterans’ experiences of PTG over time.  相似文献

Abstract

This paper summarizes the results of published studies in which physical activity has been performed by patients with panic disorder. Several case studies of apparent exercise-induced panic attacks were found. However, in field studies that involved ambulatory monitoring of panic disorder patients only 1 of 91 panic attacks that were monitored actually occurred while the test subject was engaged in moderately intense physical activity. Moreover, only five panic attacks occurred in association with 444 exercise bouts performed by 420 panic disorder patients in laboratory settings despite the fact that exercise induces somatic signs and symptoms of anxiety. Thus, the weight of the published evidence shows that acute physical activity does not provoke panic attacks in panic disorder patients.  相似文献

Violence in military families remains a vexing problem. Since the advent of the Global War on Terror, there is inconsistent evidence that the prevalence of family violence is increasing, particularly during and after military deployments. However, child neglect appears to increase significantly during military deployments. The military has developed family advocacy programs designed to keep families safe and intervene to reduce the deleterious effects of exposure to family violence. This is one of the first studies to examine the quality with which a family advocacy program is implemented and the degree to which families engage with the program. To conduct this study, the case files of 226 families who came in contact with the Army Family Advocacy Program (FAP) and whose cases were closed in 2013 were reviewed and coded across several implementation and service outcomes. These included involvement of qualified staff, whether or not appropriate victim and offender assessments were completed, degree of inter-agency communication, and appropriateness of referrals, among others. Soldier and family member participation in FAP and other Army-sponsored programs designed to reduce violence was also assessed. Generally speaking, the Army Family Advocacy Program was implemented with high quality, established processes and procedures for handling cases were largely followed, and FAP staff responded rapidly and thoroughly to reported abuse. However, family engagement with Army services and supports was low. Developing robust approaches to engaging families in family programming must be a high priority going forward.  相似文献
