【摘要】：面孔作为一种重要的视觉刺激,其中包含大量的生物性和社会性信息。前人做了大量的关于面孔识别的研究,面孔信息按照不同的分类标准可以分成不同的类别,按照信息的变化属性,可分为两种信息,可变信息和不变信息,其中表情信息属于可变信息,性别信息属于不变信息。对于这两种信息的关系,前人研究结果不一致,认为二者的关系是相互独立或者是相互影响的。基于二者之间的关系,本研究认为二者之间的关系是受到具体任务形式调节的,由于任务形式的变化,导致面孔信息提取时选择性注意的变化,从而调节二者之间的关系。本研究使用男性和女性的高兴、生气表情,沿用前人的研究范式,Garner实验范式。实验一探讨面孔性别信息对表情效价判断的影响,实验二探讨表情效价对性别信息识别的影响,实验三中,通过转变任务形式,由面孔表情图片的效价判断转变为表情唤醒度判断,探讨性别信息对表情唤醒度判断的影响。实验一和实验二结果表明面孔性别和表情效价之间的关系是交互影响的。在表情效价判断任务中,性别变化影响面孔效价判断,基线条件正确率显著大于过滤线条件,高兴表情识别中过滤线条件反应时显著长于基线条件反应时。面孔早期结构编码阶段过滤线条件潜伏期显著早于基线条件潜伏期,在晚期加工阶段,女性图片基线条件潜伏期早于过滤线条件,即在面孔结构编码阶段和晚期加工阶段面孔性别对表情效价均造成影响;在面孔性别判断任务中,面孔表情效价变化对性别识别有影响,男性高兴表情过滤线条件反应时显著大于基线条件反应时;在面孔表情唤醒度判断任务中,中央区生气表情图片基线条件潜伏期显著早于过滤线条件潜伏期,顶区生气表情图片过滤线条件潜伏期显著早于基线条件潜伏期,表情唤醒度判断在早期面孔结构编码阶段不受性别变化的影响,而在晚期加工阶段受到性别变化的影响。结果表明通过改变任务形式,其中选择性注意起到重要的作用,通过自上而下的选择性注意的调节,调节了面孔信息的提取和加工,从而影响二者之间的关系,得到二者关系符合诊断式识别模型和多级整合模型。
[Abstract]:As an important visual stimulus, face contains a lot of biological and social information.Face information can be divided into different categories according to different classification criteria, and can be divided into two kinds of information, variable information and invariant information, according to the changing attributes of information.The expression information belongs to the variable information, the gender information belongs to the invariant information.As to the relationship between these two kinds of information, the previous studies do not agree that the relationship between them is independent or mutual influence.Based on the relationship between the two, this study considers that the relationship between the two is regulated by the specific task form, because of the change of task form, resulting in the change of selective attention in face information extraction, so as to regulate the relationship between the two.In this study, male and female happy and angry expressions were used.In experiment 1, the influence of facial gender information on the judgment of facial expression titer is discussed, and in experiment 2, the influence of facial expression titer on gender information recognition is discussed. In experiment 3, by changing the form of task,The effect of gender information on facial expression arousal was discussed from the value judgment of facial expression picture to the judgment of facial expression arousal degree.The results of experiment 1 and 2 show that the relationship between facial gender and facial expression titer is interactive.In the task of judging facial expression titer, gender change affected face titer judgment. The correct rate of baseline condition was significantly higher than that of filtering line condition, and the response time of filtering line condition in happy expression recognition was significantly longer than that of baseline conditional reaction.In the early phase of facial structure coding, the incubation period of filtering line condition was significantly earlier than that of baseline condition. In the late processing stage, the baseline condition latency of female image was earlier than that of filtering line condition.In the face structure coding stage and the late processing stage, the face gender affects the facial expression titer, and in the face sex judgment task, the change of the facial expression titer has an effect on the gender recognition.In the task of judging facial expression arousal degree, the baseline incubation period of facial facial expression images was significantly earlier than that of filtering line condition.The conditional incubation period of facial expression filter line in the top region was significantly earlier than that in the baseline condition. The facial expression arousal degree was not affected by gender change in the early phase of facial structure coding, but by gender change in the late processing stage.The results show that selective attention plays an important role by changing the form of task, and adjusts the extraction and processing of face information through the regulation of top-down selective attention, thus affecting the relationship between the two.The relationship between them is in accordance with the diagnostic identification model and the multilevel integration model.
