【摘要】：面孔识别是社会活动、人际交往等一系列社会化过程中的重要技能。面孔识别过程中使用最为广泛的分类方法是构形加工与特征加工。许多学者已经对两种加工方式进行了一系列广泛而深入的研究与探讨。其中,对于构形加工的研究又逐渐细化为一级构形加工、整体加工和二级构形加工。情绪面孔识别是面孔识别研究中的一个重要组成部分。基于一级构形加工和整体加工对情绪面孔识别的影响研究已有很多,但对于探讨二级构形加工与特征加工对情绪面孔识别的影响却鲜有涉足。本文为弥补此方面的研究空白,采用了实验研究的方法对此展开了探讨。本研究使用修改的面孔维度任务来探讨信息类型(构形和特征)与区域(眼睛和嘴巴)在识别情绪面孔中的作用及其倒置效应。本文采用两个研究检验了这一关系。研究一意在探讨二级构形加工对情绪面孔识别的影响,且考查这种影响具体体现在面孔的哪一区域以及倒置效应在其中的作用。结果发现,二级构形加工对识别不同情绪面孔的影响是一致的,且无论识别何种情绪面孔,眼部区域的辨别力都高于嘴部区域。倒置效应会显著降低对二级构形信息变化的敏感性。研究二探讨了特征加工在情绪面孔识别中的影响以及倒置效应。结果发现,特征加工对情绪面孔辨别力的影响不同,即愤怒情绪面孔的辨别力高于愉快面孔和中性面孔,但在不同区域上,特征加工对情绪面孔识别的影响是不同的。倒置效应破坏了识别不同情绪眼部区域特征信息变化的辨别力差异,但并未破坏不同情绪嘴部区域之间的辨别力差异。本研究发现,二级构形加工与特征加工对识别情绪面孔的辨别力具有不同的影响。二级构形加工对情绪面孔识别的影响是一致的,而特征加工对不同情绪面孔具有不同的影响。二级构形加工与特征加工对识别正立情绪面孔的影响在不同的面部区域上表现不同。倒置效应会明显破坏情绪面孔的识别,无论是二级构形信息还是特征信息的变化,情绪面孔的辨别力都会明显下降。此外,倒置效应对于二级构形加工与特征加工的破坏,还会随着情绪与区域的影响而有所不同。
[Abstract]:Face recognition is an important skill in a series of socialized processes such as social activities and interpersonal communication. The most widely used classification methods in face recognition are configuration processing and feature processing. Many scholars have carried on a series of extensive and thorough research and discussion on two kinds of processing methods. Among them, the research of configuration processing is gradually refined into first order configuration processing, integral processing and secondary configuration processing. Emotional face recognition is an important part of face recognition research. There have been many studies on the effect of first-order configuration processing and holistic processing on emotional face recognition, but there are few studies on the effects of secondary configuration processing and feature processing on emotional face recognition. In order to make up for the blank in this field, this paper uses the method of experimental study to discuss this problem. In this study, the role of information types (configuration and features) and regions (eyes and mouth) in the recognition of emotional faces and their inversion effects were investigated using the modified face dimension task. This paper uses two studies to test this relationship. The first study aims to explore the effect of secondary configuration processing on emotional face recognition, and examine which region of face and the role of inversion effect. The results showed that the effect of secondary configuration processing on the recognition of different emotional faces was consistent, and the discrimination power of eye region was higher than that of mouth region no matter what emotional face was recognized. The effect of inversion significantly reduces the sensitivity to the change of secondary configuration information. The second study discussed the effect of feature processing on emotional face recognition and inversion effect. The results show that the effect of feature processing on emotional face discrimination is different, that is, the discriminating power of angry face is higher than that of pleasant face and neutral face, but in different regions, the effect of feature processing on emotional face recognition is different. The inversion effect destroys the discriminative power difference in distinguishing the characteristic information of different emotional eye regions, but it does not destroy the discriminative power difference between the different emotional mouth regions. In this study, it is found that secondary configuration processing and feature processing have different effects on the discrimination of emotional faces. The effects of secondary configuration processing on emotional face recognition are consistent, while feature processing has different effects on different emotional faces. The effects of secondary configuration processing and feature processing on the recognition of orthotropic emotional faces are different in different facial regions. The inversion effect will obviously destroy the recognition of emotional faces. Whether the change of secondary configuration information or characteristic information, the discriminative power of emotional faces will decrease obviously. In addition, the effects of inversion on secondary configuration processing and feature processing may vary with the influence of emotion and region.
