以321名少数民族大学生为被试,考察了民族接触(与汉族)、交往态度、民族认同、民族本质论、民族刻板印象和群际焦虑等变量,以整合的视角探讨了民族接触促进民族交往的机制问题。研究结果表明:民族接触通过降低群际焦虑和民族认同、减弱消极刻板印象和民族本质论而间接促进了民族交往,民族认同在民族接触和民族本质论之间、消极刻板印象在民族接触和群际焦虑之间存在中介作用。这项整合的研究理论上丰富了群际接触减少偏见的机制研究,发现了新的中介变量,对促进民族交往的实践具有指导意义。 相似文献

本研究采用边界范式,控制单字词N+1的预视加工负荷和词N+2首字的预视信息类型,探讨了汉语阅读中词N+2的预视对高频单字词N+1加工产生的影响。结果发现,当词N+1的预视为低加工负荷时,词N+2首字的预视对词N+1的加工产生了显著的影响;当词N+2首字的预视字与词N+1正字法相似,并且只呈现在副中央凹中时,显著的阻碍了词N+1随后的加工。结果表明,副中央凹中词N+2能够获得预视加工,可能获得正字法预视信息并对随后词N+1的加工产生了影响,并且这种影响受词N+1的预视加工负荷的调节。实验结果符合注意梯度指引模型的假设。 相似文献

This special issue of Memory brings together research from around the globe, from Japanese, Chinese and East Indian cultures, to American and European societies, to the Caribbean, to Turkey and to Australia and New Zealand, which examines how and why people, from childhood to old age, remember the personal past in daily life. This journey highlights the important role of the cultural context in shaping the functional usages of autobiographical memory. We illuminate six major contributions of cross-cultural research to a broader and deeper understanding of the functions of autobiographical memory, and call attention to the filed that memory research must “go global.” 相似文献

This study investigated explicit knowledge of autobiographical memory functions using a newly developed questionnaire. European and Asian American adults (N = 57) and school-aged children (N = 68) indicated their agreement with 13 statements about why people think about and share memories pertaining to four broad functions—self, social, directive and emotion regulation. Children were interviewed for personal memories concurrently with the memory function knowledge assessment and again 3 months later. It was found that adults agreed to the self, social and directive purposes of memory to a greater extent than did children, whereas European American children agreed to the emotion regulation purposes of memory to a greater extent than did European American adults. Furthermore, European American children endorsed more self and emotion regulation functions than did Asian American children, whereas Asian American adults endorsed more directive functions than did European American adults. Children's endorsement of memory functions, particularly social functions, was associated with more detailed and personally meaningful memories. These findings are informative for the understanding of developmental and cultural influences on memory function knowledge and of the relation of such knowledge to autobiographical memory development. 相似文献

How accurate are children when dating very long-term memories? Chinese and European Canadian 8-, 11-, and 14-year-olds (N=344) recalled and dated memories from before they went to school in a memory fluency task. Parents provided verification of children's memories and age estimates. Across all age and culture groups, a telescoping effect (i.e., events were dated as taking place more recently than they actually did) was found for earlier memories (before 48 months) and a reverse telescoping effect for later memories (after 48 months). Older children showed a greater tendency to telescope earlier memories and a weaker tendency to reverse telescope later memories than did younger children. Euro-Canadian children showed larger reverse telescoping than Chinese children. These are the first systematic findings concerning the accuracy of children's dating of very long-term memories. They shed new light on the phenomenon of telescoping and have implications for research on childhood amnesia. 相似文献

急性心肌梗死(AMI)患者的治疗关键在于早期诊断和及时开通闭塞的冠状动脉,患者在发病后能否及早到院接受再灌注治疗,对患者的治疗效果和预后有重要影响.院前延误时间(PDT)即为从患者出现症状至到达医院接受治疗的时间.AMI患者就医大多是延迟的,主要原因是患者不能决定自己的症状是否需要治疗,也就是患者决定就医时间延长.本研究目的是分析造成急性心肌梗死患者院前延误的相关影响因素,为患者赢得最佳治疗时间提供理论依据. 相似文献
