焦虑与注意偏向的研究是近年来情绪与认知领域的热点。为探讨特质焦虑个体的注意偏向特点及其返回抑制能力是否受不同线索的调节, 采用特质焦虑量表筛选高特质焦虑大学生29名, 低特质焦虑大学生28名完成线索-靶子任务。要求被试在提示线索消失后, 对位置进行快而准地辨别反应, 分别探索中性和情绪性提示线索下被试的返回抑制。结果发现:(1)在中性线索条件下, 高焦虑个体平均反应时慢于低焦虑个体。(2) 在情绪线索条件下, 高焦虑个体在负性线索下的反应时小于在正性线索下的反应时; 高、低焦虑个体在各种SOA条件下均出现了返回抑制, 但各组返回抑制量受到情绪线索的调节:在正性情绪线索条件下, 两组返回抑制量没有显著差异; 在负性情绪线索下, 高焦虑个体返回抑制量显著小于低焦虑个体。这表明, (1)焦虑个体的注意偏向受到刺激信息的影响:只对负性情绪线索出现注意警觉; (2)只有在涉及负性情绪信息时高、低焦虑个体返回抑制能力才有差异, 高焦虑个体存在对负性情绪线索的抑制困难。 相似文献

高特质焦虑个体常表现出对威胁性刺激的选择性注意偏向的特点。然而其潜在的神经机制目前仍不清楚。通过记录高、低特质焦虑者各17名进行情绪加工时的ERP,比较了两组个体在选择性注意偏向发生的时间进程和相关的神经反应的差异。结果发现,高特质焦虑者诱发出更大的N1,进一步发现恐惧图片比中性图片诱发更大的N1;而低特质焦虑者诱发了更大的N2,特质焦虑得分越低, N2波幅越大。结果初步说明高特质焦虑者加工早期对恐惧图片分配了较多的注意资源,并且其抑制执行功能可能受损;而低特质焦虑者较晚开始区分恐惧图片和中性图片。这些结果提供了支持认知-动机模型的新证据。 相似文献

Two distinct theoretical views explain the effects of action/inaction and social normality on anticipated regret. Norm theory (Kahneman & Miller, 1986) emphasises the role of decision mutability, the ease with which one can imagine having made a different choice. Decision justification theory (Connolly & Zeelenberg, 2002) highlights the role of decision justifiability, the perception that the choice was made on a defensible basis, supported by convincing arguments or using a thoughtful, comprehensive decision process. The present paper tests several contrasting predictions from the two theoretical approaches in a series of four studies. Study 1 replicated earlier findings showing greater anticipated regret when the chosen option was abnormal than when it was normal, and perceived justifiability mediated the effect. Study 2 showed that anticipated regret was higher for careless than for careful decisions. Study 3 replicated this finding for a sample holding a different social norm towards the focal decision. Finally, Study 4 found that, when decision carefulness, normality and action/inaction were all specified, only the former showed a significant effect on anticipated regret, and the effect was again mediated by perceived justifiability. Decision justification theory thus appears to provide a better account of anticipated regret intensity in this context than does norm theory. 相似文献

两个实验均以汉字为材料,采用2×3被试内设计,分别使用语义范畴判断和语音判断任务考察了汉字频率对阅读中情绪价效应的影响。结果发现:在语义任务中,情绪价与字频之间交互作用不显著,低频消极字和积极字的反应时均快于中性字,高频消极字的反应时也快于中性字,但高频积极字与中性字之间无差异。在语音任务中,情绪价与字频之间交互作用显著,低频消极字和积极字的反应时均快于中性字,而高频字的语音通达则不受情绪价的影响。汉字阅读中的情绪价效应不是自动化的过程,会受到字频与任务形式的影响。 相似文献

Adult questionnaire respondents reported, for each of a number of events, if they had experienced that event during childhood and, if so, if they remembered the experience or merely knew it had happened. Respondents also rated the emotion of each event and judged whether they would remember more about each reportedly experienced event if they spent more time trying to do so. Study 1 respondents were 96 undergraduates, whereas Study 2 tested 93 community members ranging widely in age. Respondents often reported no recollections of reportedly experienced events. Reportedly experienced events rated as emotional were more often recollected than those rated as neutral, and those rated as positive were more often recollected than those rated as negative. Predicted ability to remember more was related to current memory. Claims of remembering reportedly experienced events increased with age, but predicted ability to remember more about them declined with age. 相似文献

This study investigated both young men's and young women's perpetration of physical, sexual, and psychological forms of dating violence, examining predictors of violence including maternally or paternally perpetrated forms of various types of child maltreatment, as well as attitudes toward dating violence and dating violence victimization. Results of hierarchical linear regressions found that childhood experiences of maternal neglect predicted men's physical perpetration, and childhood sexual abuse predicted women's sexual perpetration and men's psychological perpetration. Further, positive attitudes toward dating violence predicted women's physical, psychological, and sexual perpetration, as well as men's sexual perpetration, and experiences of dating violence victimization were the strongest predictors of most forms of dating violence perpetration, particularly among women. Implications for future research and prevention initiatives are discussed. 相似文献
