摘要
本研究采用Navon字母任务,通过两个实验分别从行为和脑电两个层面对正性情绪如何影响注意广度进行了探讨.实验一发现高动机正性情绪下Navon字母任务的整体反应优势变小;实验二发现高动机正性情绪会使整体目标和局部目标的额区P3波幅差变小,这两个结果都表明相比与中性情绪,高动机正性情绪会缩小注意广度,支持情绪的动机维度模型.
Two experiments were designed to investigate the mechanism of the effect of positive affect on attentional scope from the behavioral and the ERP levels respectively. After viewing high motivating positive stimuli,participants showed less bias toward global targets in the behavioral experiment,and less frontal P3 amplitude differences between global and local targets in the ERPs experiment. These results in dicated that： compared with neutral creations, high motivating positive emotions can narrow attentional scopes,which support the motivational dimensional model of affect.
