构形信息和特征信息在面孔整体加工中的作用

The role of configural information and featural information in face holistic processing

面孔整体加工的一种表现形式是目标半脸与无关半脸的信息在面孔识别过程中发生自动化整合。实验采用组合面孔任务,相继呈现两张面孔(均为目标半脸和无关半脸组合而成),要求被试对目标半脸做异同判断,考察无关半脸上的构形信息变化或特征信息变化对目标半脸识别的影响,以此检测这两类信息在面孔整体加工中的作用。实验结果显示:无关半脸上的构形信息和特征信息变化对目标半脸的异同判断都产生了显著影响,且二者造成的影响有显著正相关。因此,构形信息和特征信息在面孔整体加工中都具有重要作用,二者共同参与了面孔的整体加工。这一发现完善了面孔整体加工的理论。

One of the manifestations of face holistic processing is the automatic integration of the target half-face and irrelevant half-face information during face recognition.In the experiment,the composite-face task was used to display two faces successively(both composed of the target half-face and the unrelated half-face).The participants were required to judge wlether the target halves of two faces were same or different,so as to investigate the impact of the configural information changes or the featural information changes of the irrelevant half-face on the recognition of the target half-face,thereby testing the role of the both in face holistic processing.Results show that the changes in both configural information or featural information of the irrelevant half-face have significantly affected the judgement of the target half-face,and the effects of the two types of information have significant positive correlation,indicating that both the configural information and the featural information play an important role in face holistic processing,and both have jointly participated in face holistic processing.This discovery is an improvement of the theory of face holistic processing.
