Two studies examined individual and environmental forces that affect engagement in prosocial behavior. Self-determination theory was used to derive a model in which autonomy orientation and autonomy support predicted satisfaction of three core psychological needs, which in turn led to engagement in prosocial activities. In Study 1, college students reported their engagement in various prosocial activities, and completed measures of autonomy orientation, parental autonomy support, and general need satisfaction. In Study 2, volunteer workers completed measures of autonomy orientation, work autonomy support and need satisfaction at work. The number of volunteered hours indicated the amount of prosocial engagement. Results across the studies showed that autonomy orientation was strongly related to engagement in prosocial behavior, while autonomy support was modestly related. Need satisfaction partially mediated the effect of autonomy orientation, and fully mediated the effect of autonomy support. Interestingly, autonomy support predicted lower volunteer turnover. Implications for how prosocial behavior can be motivated are discussed. 相似文献

In this study, we investigated the prevalence of women's sexual aggression against men and examined predictors of sexual aggression in a sample of 248 women. Respondents reported their use of aggressive strategies (physical force, exploitation of a man's incapacitated state, and verbal pressure) to make a man engage in sexual touch, sexual intercourse, or oral sex against his will. Childhood abuse, gender role orientation, ambiguous communication of sexual intentions, level of sexual activity, and peer pressure were included as predictors of sexual aggression. Almost 1 in 10 respondents (9.3%) reported having used aggressive strategies to coerce a man into sexual activities. Exploitation of the man's incapacitated state was used most frequently (5.6%), followed by verbal pressure (3.2%) and physical force (2%). An additional 5.4% reported attempted acts of sexual aggression. Sexual abuse in childhood, ambiguous communication of sexual intentions, high levels of sexual activity, and peer pressure toward sexual activity were linked to an increased likelihood of sexual aggression. The findings are discussed in relation to the literature on men's sexual aggression. 相似文献

It is well established that categorising the emotional content of facial expressions may differ depending on contextual information. Whether this malleability is observed in the auditory domain and in genuine emotion expressions is poorly explored. We examined the perception of authentic laughter and crying in the context of happy, neutral and sad facial expressions. Participants rated the vocalisations on separate unipolar scales of happiness and sadness and on arousal. Although they were instructed to focus exclusively on the vocalisations, consistent context effects were found: For both laughter and crying, emotion judgements were shifted towards the information expressed by the face. These modulations were independent of response latencies and were larger for more emotionally ambiguous vocalisations. No effects of context were found for arousal ratings. These findings suggest that the automatic encoding of contextual information during emotion perception generalises across modalities, to purely non-verbal vocalisations, and is not confined to acted expressions. 相似文献
