二维面孔识别中族群信息与情绪信息的关系及其影响因素

Processing relationship between ethnic group information and emotional information and the influence of social contact degree in face recognition

选取80名藏族学生,采用学习-再认范式,考察二维信息面孔识别中族群信息与情绪信息间的加工关系,以及社会接触程度对这种加工关系的影响。结果显示:(1)对于低社会接触者而言,族群信息与情绪信息加工彼此独立;族群信息加工不受情绪信息影响,存在异族效应;(2)对于高社会接触程度者而言,族群信息加工受情绪信息影响,异族效应出现反转。可见,面孔识别中二维信息的加工关系并非固定不变,考察面孔识别应同时考虑信息的维度和社会接触程度。

Ninety-eight Tibetan students participated in this investigation that focused on the relationship between ethnicity and emotion during facial recognition.Recognition of Han Chinese faces was tested using the Learning-Recognition paradigm under different levels of social exposure to Han Chinese.Results showed that:(1) Ethnicity and emotional information were processed independently when social contact levels were low;Ethnic information processing was not affected by emotional information and an other-race effect were observed;(2) When social contact levels were high,ethnicity processing was affected by emotional information and the other-race effect was reversed.Because the dimensions in two-dimensional information processing during facial recognition do not have a fixed relationship,both facial information and the level of social contact between individuals should be considered when investigating face recognition.
