Research in the information processing on social cognition

人的知觉、人的记忆和面孔识别是社会认知的重要模块。本研究的目的是探讨这些模块之间的关系，并建立一个新的社会认知理论模型，作为自我知识信息加工的框架。在面孔识别中，我们试图确定视觉信息的定量因素，以分类面部表情。我们就能弄清面部表情的特征。我们还考察了认知加工时间中出现的典型性效应。我们讨论了面孔再认的信息加工过程，在人的记忆中，我们采用自我生成范式考察了自我参照效应。结果发现，自感效应可以用记忆网络理论来解释。我们还发现，影响自我指涉效应。对具有积极情感的人名进行的附带自由回忆和附带线索回忆测验，比对具有消极情感的人名进行的附带自由回忆和附带线索回忆测验显示出更强的自我生成效应。记忆的组织性是用网络中节点的连接程度来解释的。自我知识方面，我们从多面自我的角度考察了自我的表征。结果，我们发现，人们认为自己比别人有更多的属性。我们还从理论上讨论了自我的动机方面对自我知识的影响，并讨论了网络模型对解释上述结果的有效性。

Person perception, person memory, and face recognition are important modules of social cognition. The purpose of this study is to examine the relations of these modules and to built a new theoretical model of social cognition as a framework for the information processing of self-knowledge.On face recognition, we tried to identify quantitative factors of visual information to categorize facial expressions. We could clarify the features of facial expressions. We also examined the typicality effect appearing in cognitive processing time. We discussed the information processing on face recognition.On person memory, we examined self-referent effect by use of the self-generation paradigm. As a result, we found that selfreferent effect was explained from a network theory of memory. We also found that affects influenced self-referent effect. Incidental free and cued recali tests of persons' name which had positive affect, showed stronger self-generation effect than those of persons' name which had negative affects. Organizational aspect of the memory was explained in terms of the degree of the connection of nodes in the network.On self-knowledge, we investigated the representation of self from the view of the multifaced self. As a result, we found that persons perceived themselves to have more attributes compared to others. We also theoretically discussed the influence of motivational aspects of self, in relation to affect, on selfknowledge.We discussed the validity of the network model to explain above-mentioned results.
