正性情绪对注意促进效应的影响

The Influence of Positive Emotion on the Attentional Boost Effect

当被试完成一项与背景刺激无关的目标探测任务时,对背景刺激进行编码记忆,之后的测验成绩表明,对与目标项目匹配呈现的刺激的记忆比与分心项目匹配呈现的刺激的记忆更好,即注意促进效应。近期研究表明,这一效应受词频、正字法特异性、负性情绪等背景材料独特性的调节。为了延伸这一研究结论适用的领域,本文采用正性情绪图为背景材料,探讨正性情绪特征是否也能调节注意促进效应。结果发现,在正性和中性情绪图中都表现出注意促进效应,并且二者没有显著差异,即正性情绪对注意促进效应没有产生调节作用。

When the subjects completed a target-detection task that was unrelated to the background stimulus,they coded and memorized the background stimulus.The results of the later tests showed that stimulus encoded with to-be-responded targets was remembered better than stimulus encoded with distractors,which was the attentional boost effect(ABE).Recent studies have shown that this effect was regulated by the uniqueness of background information,such as word frequency,orthographic distinctiveness and negative emotions.In order to extend the applicable field of this research conclusion,this paper uses the positive emotion picture as the background material to explore whether the positive emotion characteristics can also regulate ABE.The results showed that both positive and neutral emotion pictures showed ABE,and there was no significant difference between them.That is,positive emotion had no regulating effect on ABE.
