人格特质对选择性加工偏向的影响

采用词性辨别和注意探测任务，考察了神经质和外倾性对选择性加工偏向的影响。结果表明：（1）放试在选择信息时存在特质一致性倾向；（2）在单一刺激条件下，当刺激词呈现时间为0．5s时，高神经质对所有效价词的RT均快于低神经质；而当呈现时间为1．0s时，外倾者比内倾者的反应潜伏期更短4（3）双重刺激条件下的选择性加工偏向比单一刺激条件更明显；（4）在词性辨别任务中．刺激词呈现时间只影响了神经质被试对情绪词的RT；在注意探测任务中，呈现时间对内外倾被试的加工偏向影响不显著。

The Influence of Personality Traits on Selective Processing Biases

The main purpose was to explore the influence of personality traits about neuroticism and extroversion on selective processing biases by adopting lexical identification task and attentional probe task.The results were as follows:(1) Selective processing biases were the cognitive character in extreme subjects,and there were distinct trait congruency dispositions when they selected information.(2) Under the single-stimulus condition,when the word presentation time was 0.5s,the RT of high neuroticism towards all emotional valence words was faster than that of low neuroticism.However,the reaction latency of extroverts towards all types of words was shorter than that of introverts when the time became 1.0s.(3) Selective processing biases of subjects were more notable under double-stimulus condition than that of single-stimulus.(4) In the lexical identification task,the presentation time only affected neuroticism subjects' RT of emotional valence words, but in the attentional probe task,the effects of presentation time on selective processing biases were less notable among extroversion subjects.
