Abstract

Does emotion affect how people see? We investigated the effects of emotion and attention, as well as their conjoint effect, on contrast sensitivity, a dimension of early vision. We manipulated the emotional valence and the attentional distribution of cues preceding a target stimulus and asked observers to judge the orientation of the target as contrast varied. This study provides the first behavioral evidence that (a) emotion enhances contrast sensitivity irrespective of attention and (b) emotion potentiates the effect of attention on contrast sensitivity.

摘要

情绪会影响人们的视觉感知吗?我们研究了情绪和注意力及其联合效应,对早期视觉的一个维度——对比敏感度的影响。我们操纵了目标刺激之前线索的情绪效价和注意力分布,并要求观察者在对比度变化时判断目标的方向。这项研究提供了首个行为学证据,即:(a)无论注意力如何,情绪都会增强对比敏感度;(b)情绪会增强注意力对对比敏感度的影响。
