【摘要】 时间整合是指相继呈现的序列事件被加工为一个整体表征,通过把完整的面孔表情分割成3部分,按照不同的时间间隔相继呈现,考察面孔表情时间整合的时程效果.结果发现:①时间整合的时程(SOA)要受到刺激材料的意义性的影响,面孔表情的时间整合的时程要长于面孔.②面孔表情的时间整合时程也存在类型差异,喜悦表情的时间整合时程要明显长于愤怒和悲伤2种表情.更多还原

【Abstract】 Temporal integration refers to the process of perception processing,by which the successively separated stimuli are combined into a significant representation.In this study,the time course of temporal integration was examined in different facial expressions,by which each of three whole facial expression pictures was segmented into three parts,each including a salient facial feature: eye,nose or mouth;and then these parts were presented sequentially to the participants by different interval duration.The results showed inversion effects in that the time course of temporal integration(SOA) was influenced by stimulus feature,and the time course of temporal integration in facial expression was longer than in face,and in that a type difference was existed in the time course of temporal integration in facial expression,and the time course of temporal integration in happy expression was longer than that in angry or sad expression.更多还原
