面孔部件相似性判断研究

用Morph变形方法构建家族相似性面孔部件样例,采用多级估量法探讨分类活动中面孔部件相似性判断问题。结果发现,部件样例对部件原型的隶属度及部件样例对整体原型中对应部件的隶属度与部件样例变形百分比间是3次函数关系;耳朵、脸型、眼睛等部件样例对整体原型中对应部件的隶属度小于其对部件原型的隶属度,嘴巴样例对整体原型中嘴巴部件的隶属度高于其对部件原型的隶属度。表明面孔部件物理相似性与心理相似性间是3次函数关系;整体原型中其他部件降低了耳朵、脸型、眼睛等部件样例对整体原型中对应部件的隶属度,而提高了嘴巴样例对整体原     

Constructing Self-Identity: Minority Students’ Adaptation Trajectories in a Chinese University

Researchers have gone beyond identity status and been putting more and more emphases on the dynamic process of identity development and its contextual embeddedness. Study of individual’s adaptation to the multicultural background is a good point of penetration. Because of the differences in regional conditions and cultural traditions, the minority youths who go to university in the mainstream culture would have special experiences and challenges in the development of their self-identities. Semi-structured interview and narrative were used in this research to discover the characteristics of the self-identity constructing processes of Mongolian undergraduates in a Shanghai university context. Their identity constructing process could be divided into three stages: difference-detecting, self-doubting and self-orienting. The main efforts of identity constructing in each stage could all be described as self-exploring and support-seeking. Special contents of internal explorations and sources of support were distinguished at different stages. As relative results, three main types of self-orientation were revealed: goal-oriented, self-isolated and unreserved assimilated. The characteristics of them are quite similar to those of three identity processing styles proposed by Berzonsky, which indicates there are some common elements lying in all self-development processes of adolescences and young adults. Ethnicity and culture could be background and resource or what Côté called identity capital that impacts the special course of self-identity constructing under similar principles. Different attitudes towards and relationships with their own ethnicity and new surroundings separated the three types of students from each other and interacted with the developmental characteristics and tendencies of their ethnicity identifications and self identities. It was found that minority youths’ self-identity constructing was based on their needs of self-value and interacted with their ecological niche constructing. Take ethnicity attachment and ethnicity responsibility as a typical example: the setting up of bi-direction relationship between individuals and their ethnicity (or other identity-related factors) was very important for minority youths to expand and integrate themselves. We also presented in detail our methodological exploring process so as to illuminate the limitation of traditional methods and the necessity and importance of methodological reform. Methodologically, both emic and etic positions were taken, interview and narrative approaches were adopted and individual angle of analysis was kept in the research. They were all proved to be effective to provide insight into the dynamic process of self identity constructing.     

Evaluation is a Dynamic Process: Moving Beyond Dual System Models

Over the past few decades, dual attitude/process/system models have emerged as the dominant framework for understanding a wide range of psychological phenomena. Most of these models characterize the unconscious and conscious mind as being built from discrete processes or systems: one that is reflexive, automatic, fast, affective, associative, and primitive, and a second that is deliberative, controlled, slow, cognitive, propositional, and more uniquely human. Although these models serve as a useful heuristic for characterizing the human mind, recent developments in social and cognitive neuroscience suggest that the human evaluative system, like most of cognition, is widely distributed and highly dynamic. Integrating these advances with current attitude theories, we review how the recently proposed Iterative Reprocessing Model can account for apparent dual systems as well as discrepancies between traditional dual system models and recent research revealing the dynamic nature of evaluation. Furthermore, we describe important implications this dynamical system approach has for various social psychological domains.     

基于能力的医学教育的认识与思考

基于能力的医学教育(CBME)在美国等发达国家被广泛用于住院医师培训.其注重毕业后培训的实际效果,以学习者为中心,过程更为灵活.通过培训方法的改革及形成性评估的应用,形成“实践-反馈-提高-再实践”的过程,使住院医师实际能力获得提高.近年来,CBME已延伸至本科教学中,并将对我国的医学教育事业产生更大的影响.     

基于视听双通道的音乐情绪冲突效应及优势通道研究

为探讨基于视听双通道的音乐情绪冲突效应、冲突情境下的优势加工通道和音乐经验对结果的影响,本研究采用音乐表演视频为材料,比较音乐组和非音乐组被试在一致型和不一致型视听双通道下的情绪评定速度、准确性及强度。结果发现:(1)一致型条件下的情绪评定更准确且更强烈;(2)不一致型条件下,被试更多以听觉通道的情绪线索为依据进行情绪类型评定;(3)非音乐组被试比音乐组被试更依赖视觉通道的情绪线索。结果表明:通道间情绪信息的不一致阻碍了音乐情绪加工; 听觉通道是音乐情绪冲突情境下的优势加工通道; 音乐经验降低了情绪冲突效应对音乐组被试的干扰。     

恐惧学习的发展认知神经机制研究回顾与展望

恐惧可以帮助个体快速地评估危险情景,并调动生理和行为反应来应对危险刺激。恐惧发展始于婴儿时期,神经回路表现为杏仁核未参与恐惧反应,但杏仁核功能连接可以预测早期恐惧反应;发展到童年期的恐惧学习特点为安全学习不足和过度泛化,其根源是负责辨别刺激的海马还处于发育中;进入青春期恐惧加工主要特征是由于前额叶发育较晚导致的消退能力弱。恐惧虽有益于人类生存,但恐惧异常会引发焦虑障碍,本文从恐惧的习得、消退和泛化三个阶段,对比了焦虑与健康青少年的恐惧学习差异。最后,文章从增加婴儿时期研究、创新青少年恐惧研究范式和开发安全有效的干预手段三个方面对未来研究提出展望,以期进一步推动恐惧研究的发展。     

老年人医疗语篇理解的影响因素和补偿模型

医疗语篇理解是老年人实现自我照护的关键因素,改善老年人医疗语篇理解有助于提高其生存质量并节约医疗成本。本文整理了老年人医疗语篇理解的影响因素,包括加工能力等老年人个体因素和可读性等语篇设计因素,并在此基础上提出了老年人医疗语篇理解补偿模型。该模型尝试阐述上述各影响因素中,那些随龄衰退的因素(如加工能力),如何从别的因素中得到补偿(如医疗知识),从而支撑老年人的医疗语篇理解。补偿模型有利于干预研究的设计,但也还有待更多的实证研究。
