【摘要】：注意偏向研究一直是心理学研究中的一个热点，以往研究成果多集中于研究情绪障碍的被试，并且得出其负性偏向的结论。但是关于正常个体的注意偏向研究却并未取得一致性结论，有研究表明注意资源的多少可能是导致其结果分歧的一个原因。本研究基于前人研究结论与成果，探讨正常个体在注意资源紧张和注意资源充足两种不同条件下的注意偏向。本研究采用线索-靶范式操纵注意资源变量，即有效线索为注意资源充足条件，无效线索为注意资源紧张条件。实验一以贵州师范大学27名本科生为被试，采用三种不同情绪水平的面孔作为刺激材料，考察正常个体分别在注意资源紧张和注意资源充足两种条件下，对不同情绪效价的面孔图片的注意偏向及其特点。实验二以贵州师范大学27名本科生为被试，采用三种不同情绪水平的词汇作为刺激材料；考察正常个体分别在注意资源紧张和注意资源充足两种条件下，对不同情绪效价的情绪词汇的注意偏向及其特点。实验三以贵州师范大学和贵州大学17名本科生与研究生为被试，采用三种不同情绪水平的场景图片作为刺激材料，并且与ERP技术相结合，考察正常个体分别在注意资源紧张和注意资源充足两种条件下，对不同情绪效价的场景图片的ERP脑电波形特点。本研究形成以下结论：（1）正常个体在注意资源充足条件下和注意资源紧张条件下，都表现出对正性面孔的注意偏向；（2）正常个体在注意资源充足条件下和注意资源紧张条件下，也都表现出对正性词汇的注意偏向；（3）在结合ERP技术的场景图片实验中，正常个体在注意资源充足条件下时表现出优先加工；同时也表现出对正性场景的优先加工。
[Abstract]:The study of attention bias has always been a hot topic in psychological research. Previous studies have focused on the subjects with emotional disorders and reached the conclusion of negative bias. However, the study on attention bias of normal individuals has not reached a consistent conclusion. Some studies have shown that the amount of attention resources may be one of the reasons for the divergence of results. Based on the previous research results, this study explored the attention bias of normal individuals under two different conditions: attention resource shortage and attention resource adequacy. In this study, the cue-target paradigm was used to manipulate the attention resource variables, that is, the effective clue was the sufficient condition of attention resources, and the invalid clue was the attention resource shortage condition. In the first experiment, 27 undergraduates of Guizhou normal University were used as stimulant materials with three different emotional levels, and the normal individuals were investigated under two conditions of attention resource shortage and attention resources adequacy, respectively. Attention bias and characteristics of face images with different emotional titers. In the second experiment, 27 undergraduates of Guizhou normal University were used as stimulative materials with three different emotional levels. Attention bias and characteristics of emotional vocabulary with different emotional titers. In experiment three, 17 undergraduates and postgraduates of Guizhou normal University and Guizhou University were selected as subjects. Three kinds of scene images of different emotional levels were used as stimulus materials, and combined with ERP technology. The characteristics of ERP brainwave patterns of scene images with different emotional titers were investigated under the condition of attention resource shortage and attention resource adequacy respectively. The results of this study are as follows: 1) under the condition of sufficient attention resources and tight attention resources, the normal individuals showed the attention bias to the positive faces; (2) under the condition of sufficient attention resources and tight attention resources, the normal individuals also showed the attention bias to positive vocabulary; 3) in the scene picture experiment with ERP technology, the normal individuals show priority processing when paying attention to the condition of sufficient resources, and also show the priority processing of the positive scene at the same time.
