“In-emotional blindness”? Lower detection rates for unexpected stimuli in negative compared to positive emotions

Abstract Determining how emotional experience influences attention is a long standing goal of cognitive psychologists. Emotion is often broken down into two main dimensions, arousal and valence. While many theories focus more on the influence of one dimension than the other, the systematic investigation of the independent influences of the two dimensions of emotion on attention has been slow. In order to examine the relevance of both aspects of emotion, and their interplay on attention simultaneously, in the current experiment we induced low (satisfaction) and high (happiness) arousal positive emotions and low (sadness) and high (anger) arousal negative emotions in subjects before having them complete an inattentional blindness (IB) test. In line with theories that focus on the role of valence, we found that negative emotions led to more IB than positive emotions, and that arousal did not influence attention. Implications of the results for the theoretical contributions of the dimensions of emotion to visual attention are discussed.
