特质焦虑高分大学生的内隐自我积极偏差

Implicit self-positivity bias in college students with high score of trait anxiety

目的:探索特质焦虑高分大学生的信息加工是否存在内隐自我积极偏差。方法:选取特质焦虑高分组[特质焦虑量表(T-AI)T分>60分且特质抑郁量表(T-DEP)T分<60分]和特质焦虑低分组(T-AI和T-DEP的T分均<60分)大学生各50人,采用阈上启动范式在他人和自我启动下,完成形容词属性归类任务,比较两组被试的反应时。结果:特质焦虑高分组和特质焦虑低分组启动类型和词汇类型的交互作用均有统计学意义(均P<0.001),高分组对自我积极偏差内字词的反应时快于该偏差外字词的反应时,低分组对偏差内字词的反应时快于偏差外字词的反应时。结论:特质焦虑高分大学生的信息加工存在内隐自我积极偏差,该偏差可能是焦虑个体信息加工后期对威胁刺激(自我积极偏差外字词)的回避所导致。

Objective:To explore whether there is an implicit self-positivity bias in information processing in college students with high scores of trait anxiety.Methods:Fifty college students with high trait anxiety[the T score of Trait Anxiety Inventory(T-AI)>60,the T score of Trait Depression Scale(T-DEP)<60]and 50cases with low trait anxiety[the T scores of T-AI and T-DEP<60]were selected.The two groups completed the adjective categorization task under other or self primed conditions by using the supraliminal attitude-prime paradigm,and the responses of the two groups were compared.Results:The interaction effects between primed conditions and emotional words in both groups were significant(Ps<0.001).The high trait anxiety group responded faster to the words within the self-positive bias than to the words outside.The low trait anxiety group responded faster to the words within the bias than to the words outwith the bias.Conclusion:There is an implicit self-positive bias in the information processing in college students with high trait anxiety,which is probably caused by the avoidance of threat stimuli(words outwith the self-positivity bias)by anxious individuals in the later stage of information processing.
