【摘要】：面孔中包含了大量社会信息,例如年龄、表情等,个体面孔知觉就是对面孔进行加工,提取所需的相应信息。而面孔适应是一种面孔知觉中的适应现象,即长时间看某一面孔后产生了知觉后效,当再看较为平均的面孔时,会产生与先前面孔相反的结构特征。面孔适应的研究显示,面孔维度信息如年龄维度、性别维度、种族维度均能引起面孔适应。本研究探究不同民族特征能否引发面孔适应现象,并引入维汉文化因素,探究与民族相关的文化刺激能否引发面孔适应。同时采用眼动技术,探究适应对面孔加工产生的影响。本研究有两个实验组成,实验一:采用经典的适应研究范式,以维汉民族面孔图片为适应刺激,探究民族类别内的面孔适应现象,并使用眼动仪,考察其面孔加工方式的变化。研究结果发现,维汉民族面孔能够引起面孔适应后效,即当长时间注视维吾尔族面孔/汉族后,则被试更倾向于将融合面孔判断为汉族/维吾尔族。结果还发现,在适应前后,被试对面孔加工发生了一定的改变,相比于基线,被试经过适应后对眼睛的注视时间、注视次数显著减少,而对面孔鼻子、嘴巴和眉毛的注视时间、注视次数显著增加。实验二:同样采用适应研究范式,以维汉民族文化特征图片为适应刺激,探究民族中类别间面孔适应现象,借助眼动仪观察其适应前后的注视变化。研究结果发现,以民族相关的文化特征图片同样能够引发适应后效,并且适应前后的注视趋势也发生了改变,结果与实验一相似。通过本研究的到如下结论:(1)以维汉民族面孔为适应刺激,能够引起类别内的面孔适应现象,即当长时间注视维吾尔族/汉族面孔后,则被试更倾向于将融合面孔判断为汉族/维吾尔族,产生适应后效(2)以维汉民族文化特征相关的图片为适应刺激,能够引起类别间的面孔适应现象,即当长时间注视维吾尔族/汉族文化图片后,则被试更倾向于将融合面孔判断为汉族/维吾尔族,产生适应后效。(3)民族面孔和非面孔的民族文化图片所引发的适应后效能够改变个体对面孔的加工方式,相比于基线,个体对眼睛的注视时间,注视次数减少,对其他面孔区域的注视时间,注视次数增加,适应后个体更加倾向于对面孔进行特征加工。
[Abstract]:Face contains a lot of social information, such as age, expression, etc. Individual face perception is to process face and extract the relevant information. Face adaptation is a kind of adaptation phenomenon in face perception, that is to say, after a long time seeing a certain face, it produces perceptual aftereffects. When we look at a more even face, it will produce structural characteristics contrary to the previous face. The study of face adaptation shows that face dimension information such as age dimension, gender dimension and race dimension can cause face adaptation. This study explores whether different ethnic characteristics can lead to face adaptation, and introduces Uighur and Chinese cultural factors to explore whether ethnic related cultural stimuli can trigger face adaptation. At the same time, using eye movement technology to explore the impact of face hole processing. There are two experiments in this study. The first one is to explore the phenomenon of face adaptation in the ethnic category by using the classical adaptation research paradigm and the Uighur and Han nationality face pictures as adaptation stimuli, and to investigate the change of face processing mode by eye movement instrument. The results showed that the faces of Uygur and Han nationality could induce the face adaptation effect, that is, when the face of Uygur / Han nationality was looked at for a long time, the subjects were more inclined to judge the fused faces as Han / Uygur. The results also showed that, before and after adaptation, the processing of the opposite hole changed to a certain extent. Compared with the baseline, the fixation time of the eyes was significantly decreased, while the fixation time on the nose, mouth and eyebrows of the face was significantly decreased. The number of fixation increased significantly. Experiment two: using the adaptation research paradigm and the pictures of Uighur and Han ethnic culture as adaptation stimulus, the phenomenon of face adaptation among different ethnic groups was explored, and the changes of fixation before and after adaptation were observed by eye movement instrument. The results show that images of ethnically related cultural characteristics can also induce adaptation effects and the trend of fixation before and after adaptation is also changed. The results are similar to those of experiment 1. The conclusions of this study are as follows: (1) taking the faces of Uighur and Han nationality as adaptation stimuli can cause the phenomenon of face adaptation within the category, that is, after a long period of attention to the faces of Uygur / Han nationality, The subjects were more likely to judge the fusion faces as Han / Uygur and produce adaptation effects. (2) the images related to the cultural characteristics of the Uighur and Han nationalities were taken as adaptation stimuli, which could cause the phenomenon of face adaptation between categories. That is, after looking at the cultural pictures of Uygur / Han nationality for a long time, the subjects were more likely to judge the fusion faces as Han / Uygur. (3) the adaptation effect caused by the national culture picture of national face and non-face can change the processing mode of individual face. Compared with baseline, the fixation time of individual to eyes is reduced, and the number of fixation times is decreased. The fixation time and fixation times of other facial regions were increased, and the individuals were more inclined to process the features of the face after adaptation.
