摘　　要：通过把面孔表情分割成三部分,按照不同的时间间隔以及不同的呈现时间相继呈现,考察了被试对面孔表情的时间整合效果,以此探讨时间整合的加工过程和影响因素。结果发现:(1)面孔表情的时间整合效果受时间结构和刺激材料的影响。(2)分离呈现的面孔表情能否进行时间整合与S0A的大小有关。(3)面孔表情的时间整合存在类型差异。(4)面孔表情的时间整合是在一个有限的视觉缓冲器内进行的,图像记忆和长时记忆与面孔表情的时间整合过程关系密切。Temporal integration is the process of perception processing,in which the successively separated stimuli are combined into a significant representation.It is a complicated process,which is known to be influenced by multiple factors,such as the temporal structure and stimulus components.Although this process has been explored in inter-stimulus interval in face perception,little is known about the temporal integration effect in facial expression recognition.More importantly,there has been no relevant evidence demonstrating that stimulus duration and stimulus category can affect the temporal integration of facial expression. In the present study,the part-whole judgment task was used to examine the influencing factors of temporal integration in the facial expression.In two experiments,each of three whole facial expression pictures was segmented into three parts,and each including a salient facial feature：eye,nose,or mouth.These parts were presented sequentially to the participants by some interval or presentation durations, with a fixed sequence：eye part first,nose followed,and mouth last.Following the last part,a mask,which eliminated effects of afterimages or other types of visual persistence was displayed.Then,participants were asked to judge the category of the facial expression, by pressing one of three number keys;＂1＂,＂2＂ and ＂3＂,corresponding to anger,happy and sad.In Experiment 1,each part was presented for 17ms,with five intervals of 50,100,200,600,900ms between each part in part -face condition.And a whole face as a baseline condition was presented for 50ms.Three factors were manipulated：inter-stimulus interval（50,100,200,600, 900ms）,facial expression category（anger,happy and sad）,and presentation orientation（upright vs.inverted）.A total of 72 participants were divided into six groups.And each group was randomly assigned to each of the six conditions to be tested individually.Each participant was asked to complete all possible combinations of the different levels of the facial
