An experimental study of difference of affective priming and attentional bias in young people / 中国心理卫生杂志

ABSTRACT

Objective:To explore whether there will be attentional bias under the condition of fear,disgust and positive emotional arousal. Methods:Totally 96 college students were selected as participants in this study,inclu-ding 60 males and 36 femalesaged 18-22 years. Affective priming videos were adopted to prime participants'emo-tion (dread,disgust,joviality),and then they named the color of the cognitive words (positive words,negative words,neutral words)as quickly and accurately as possible. Reaction time and correctness were recorded. E-prime was adopted to write the experimental program. The reaction time for neutral words was baseline. Results:The aver-age reaction time (RT)of color-naming tasks of negative words were shorter than that of neutral words after fright-ening affective priming[(648 ±118)ms vs. (743 ±124)ms,P<0. 01]. Furthermore,the average RT of color-na-ming tasks of positive words were also shorter than that of neutral after frightening affective priming[(683 ±123) ms vs. (743 ±124)ms,P<0. 05]. The average RT of color-naming tasks of negative words were shorter than that of neutral words after disgusting affective priming[(579 ±86)ms vs. (720 ±101 )ms;P<0. 01 ]. Moreover,the av-erage RT of color-naming tasks of positive words were shorter than that of neutral words after delighted affective priming[(634 ±122)ms vs. (716 ±141)ms;P<0. 01]. Furthermore,the average RT of disgusting priming group-were shorter than the frightening priming grouptowards negative information[(579 ±86)ms vs. (648 ±118)ms,P<0. 05 ]. Conclusion:It suggests that the youth perform more obvious attentional bias towards negative information after disgusting affective priming than the frightening one. Frightening affective priming could evidently induce the attentional bias on positive information.
