目的:探析不同人格类型群体在情绪信息加工过程中的特点。方法:采用线索-靶子范式,分析注意偏向机制中的干扰抑制、返回抑制两个方面;采用艾森克人格量表(EPQ-A),从某全日制大学本科二年级学生758人中,按EPQ中神经质和内外向两个维度的标准分高、低各12.5%选出四种典型人格类型各15名为研究对象,探析四组被试的注意偏向特征。结果:当靶子和线索出现的时间差为1000ms时,四组被试对三类情绪图片均存在返回抑制效应;图片性质主效应显著(F=1.30,P<0.05)、四组人格类型之间差异不显著(F=0.65,P>0.05)。负性图片与正性图片的返回抑制效应差异显著(F=1.71,P<0.05),反应时方差分析结果显示组别与图片性质交互作用显著(F=1.62,P<0.05)。外倾人格特质组对正性图片产生了注意警觉,四组被试对正性、负性刺激都存在注意解除困难。结论:正常人群对情绪性刺激具有选择性加工趋势,外倾个体更偏好加工正性刺激,内向不稳定组对负性刺激更为敏感。
Objective: To explore the characteristics of different personality types in the emotional information processing. Methods: Using clues-target paradigm, we analyzed two aspects of interference inhibition and return inhibition in biased attention mechanism. According to EPQ-A, from the 758 undergraduates of a full-time university, EPQ in neuroticism and internal and external dimensions of the two standard high points and low 12.5% each of the four typical personality types were selected as the research object, to investigate the four groups of participants attention bias characteristics. Results: When the time difference between the target and the cue was 1000ms, the four groups of subjects had regression inhibition effects on all the three types of emotion pictures; the main effect of the pictures was significant (F = 1.30, P <0.05); the differences among the four personality types Not significant (F = 0.65, P> 0.05). There was significant difference between the two groups (F = 1.71, P <0.05). The analysis of ANOVA showed that there was a significant interaction between group and picture (F = 1.62, P <0.05). Extraversion personality traits generated vigilance on the positive images, and the four groups of participants had difficulty in relieving positive and negative stimuli. Conclusion: The normal population has a selective processing trend for emotional stimuli, while the extraverted individuals prefer to process positive stimuli. The inward unstable group is more sensitive to negative stimuli.
