Research On The Effects Of Configural Information In Self-Face Recognition And The Difference Between Self-Face And Other-Face Recognition

Self-face recognition is an important area in research of face recognition. Previous researches of face recognition are almost all about other-face recognition, only few of them about self-face recognition. In this research, four experiments had been designed to study the effects of configural information in self-face recognition and the difference between self-face and other-face recognition. The first and third experiments were designed to explore the effects of different amount of alternation of configural information in self-face recognition, through memory recognition task. The second and fourth experiments were designed to explore the different effects of alternation of configural information between self-face and other-face recognition, through comparison task.There are five conclusions as follows:(1) There is no significant difference in performance between recognition of ture pictures and mirror pictures of their own in memory recognition task.(2) The sensitivity of participants to the changes of configural information of self-face is very high in memory recognition task, the liminal value of eye is 4.01 pixel, the liminal value of mouth is 4.92 pixel.(3) There is no significant difference in performance of participants in recognition of natural colour faces between memory recognition and comparison tasks, when configural information (eyes and mouth) was changed.(4) The performance of self-face recognition is better than that of other-face recognition.(5) There are same trends to the alternation of configural information in self-face and other-face recognition: When the degrees of alternation of configural information are enhanced, the performance of participants is increased. There are two different areas associated to the amount of alternation in participants' performance: fast-increased region and slow-increased region.
