Correlational research suggests that among older adults prosociality relates to positive emotions; yet causality remains unclear. We conducted an experiment to investigate whether visualizing a prosocial action would experience enhanced positive and lower negative emotion, and whether this would be particularly true for those with certain altruistic personality traits. Participants aged sixty and above were primed with a prosocial (helping a needy stranger), social (going out with friends), or neutral (walking down the street) induction. Results indicated that positive affect was highest among those who visualized a prosocial interaction, and that this effect was strongest among those higher in social responsibility. In contrast, less altruistically oriented participants reported higher negative affect in the prosocial condition. Thus, while prosociality promoted positive affect particularly among the socially responsible, it led to increased negative affect among those lower in altruistic orientation. Results suggest that individual differences influence older adults’ responses to exposure to prosocial involvement.  相似文献

We examined the effects of collaboration (dyads vs. individuals) and category structure (coherent vs. incoherent) on learning and transfer. Working in dyads or individually, participants classified examples from either an abstract coherent category, the features of which are not fixed but relate in a meaningful way, or an incoherent category, the features of which do not relate meaningfully. All participants were then tested individually. We hypothesized that dyads would benefit more from classifying the coherent category structure because past work has shown that collaboration is more beneficial for tasks that build on shared prior knowledge and provide opportunities for explanation and abstraction. Results showed that dyads improved more than individuals during the classification task regardless of category coherence, but learning in a dyad improved inference-test performance only for participants who learned coherent categories. Although participants in the coherent categories performed better on a transfer test, there was no effect of collaboration.  相似文献

We propose that guilt leads to forgiveness of others' transgressions. In Study 1, people prone to experience guilt (but not shame) were also prone to forgive others for past misdeeds. In Study 2, we manipulated harm‐ and inequity‐based guilt; both increased forgiveness of others' transgressions. Further, the effect of guilt on forgiveness was mediated by identification with the transgressor. In Study 3, we replicated the guilt–forgiveness relationship and examined three other plausible mediators: capability for similar wrongdoing, empathic understanding, and general identification; only identification with the transgressor satisfied the criteria for mediation. In Study 4, we induced guilt by asking participants to harm a friend or stranger. Guilt induced by harming a friend led to greater forgiveness of third‐party transgressors, and again, identification with the transgressor mediated the effect. We discuss the implications of these results for understanding how the prosocial effects of guilt extend beyond the boundaries of a single interpersonal relationship.  相似文献

This paper examines the impact of context on careers. It is based on a study of senior managers in an English local authority. It offers two important contributions: first, an empirical contribution examining how context matters to individuals in their career-making in the setting of the UK public sector. Our findings point to three aspects or faces of context: proximal events, ideology and enduring structural features. The first, context as ideology, attends to meaning-making that is collective in nature, and that incorporates concepts of power, domination, subordination and resistance. Our second refers to the enduring structural features. These are on-going trends and developments, predictable and traceable over the medium to long-term which offer rules and resources, thus structuring opportunity and constraint. Finally, the third face, context as proximal events, refers to (often unexpected) contingencies that arise at particular moments. Although bounded both spatially and temporally, they can significantly impact on career decision making. The second contribution of the paper builds upon this empirical base to develop theoretical and conceptual understanding of the link between career and context, illustrating the interconnectedness of the various faces of context and the dynamic ways in which these influence career-making over time.  相似文献

Dishabituation has been thought to be due either to reversal of the process of habituation or to a second process equivalent to sensitization superimposed on habituation. One way to address this question is by testing whether dishabituation and sensitization can be dissociated. Previous studies using this approach in Aplysia have come to different conclusions about the nature of dishabituation, perhaps because those studies differed in many respects, including (1) whether they also observed transient behavioral inhibition, and (2) whether they used test stimuli that activated the LE siphon sensory neurons or as yet unidentified sensory neurons. To attempt to resolve the apparent contradictions between the previous studies, we have explored the importance of these two factors by performing a parametric study of dishabituation and sensitization of gill withdrawal in a simplified preparation that does not exhibit transient behavioral inhibition, using two different test stimuli that are known to activate the LE (Touch) or unidentified (Not Touch) sensory neurons. We find that dishabituation and sensitization in this preparation have similar time courses and generally similar functions of shock intensity. However, under one condition, with the Not Touch stimulus 2.5 min after the shock, dishabituation has a reverse effect of shock intensity. Additional analyses suggest that dishabituation with the Not Touch stimulus 2.5 min after the shock is due to reversal of habituation, whereas 12.5 min after the shock, dishabituation is due to superimposed sensitization. These results thus suggest that dishabituation may involve either process in the same preparation, and begin to define the conditions that favor one or the other.  相似文献

Early studies of genetic effects on brain activity have been conducted to investigate primarily either the influence of polymorphisms in dopaminergic genes, especially the catechol-O-methyltransferase (COMT) gene, on prefrontal cognitive processes such as working memory, or that of polymorphisms in the serotonin transporter gene on the amygdala response to threatening stimuli. Here, we address genetic influences on the neural systems underlying cognitive-affective interactions. Specifically, we assess the effect of the COMT val158met polymorphism on frontal regulation of attention under emotional distraction. Healthy volunteers were scanned while performing a house-matching task with affectively negative versus neutral distractors. Effects of val allele load were examined on frontal regions associated with attentional control and emotion regulation, and on parahippocampal regions associated with perception of houses. As we predicted, val load correlated positively with activity in control- and task-related regions during performance under emotional distraction. These findings provide an initial step toward identifying genetic contributions to interindividual variability in recruitment of mechanisms that regulate affective processing.  相似文献
