In this article, we examine how emotional and perceptual stimulus factors influence visual search efficiency. In an initial task, we run a visual search task, using a large number of target/distractor emotion combinations. In two subsequent tasks, we then assess measures of perceptual (rated and computational distances) and emotional (rated valence, arousal and potency) stimulus properties. In a series of regression analyses, we then explore the degree to which target salience (the size of target/distractor dissimilarities) on these emotional and perceptual measures predict the outcome on search efficiency measures (response times and accuracy) from the visual search task. The results show that both emotional and perceptual stimulus salience contribute to visual search efficiency. The results show that among the emotional measures, salience on arousal measures was more influential than valence salience. The importance of the arousal factor may be a contributing factor to contradictory history of results within this field.
在本文中，我们研究了情绪和感知刺激因素如何影响视觉搜索效率。在初始任务中，我们使用大量目标/干扰项情绪组合进行视觉搜索任务。在随后的两项任务中，我们评估感知（评分和计算距离）和情绪（评分效价、唤醒度和强度）刺激属性的测量指标。在一系列回归分析中，我们接着探究这些情绪和感知测量指标上的目标显著性（目标/干扰项差异大小）在多大程度上能够预测视觉搜索任务中搜索效率测量指标（反应时间和准确性）的结果。结果表明，情绪和感知刺激显著性均有助于提高视觉搜索效率。结果表明，在情绪测量指标中，唤醒度测量指标上的显著性比效价显著性更具影响力。唤醒因素的重要性可能是该领域结果存在矛盾历史的一个促成因素。
