  • Title: Inhibition of return to negative emotion: evidence from an emotional expression detection task.
    Author: Chao HF.
    Journal: Emotion; 2010 Apr; 10(2):272-7. PubMed ID: 20364904.
    Abstract:
    After the presentation of an uninformative spatial cue, it usually takes participants more time to respond to a target that appears at the cued location when the interval between the cue and target is long. This phenomenon is named inhibition of return (IOR), implying that returning attention to the cued location is inhibited because of attentional disengagement. The present study investigated whether irrelevant emotional information is processed by the attentional system in a similar manner. Uninformative positive and negative emotional cues were presented at the center of the screen, and faces were presented as the target. An emotional expression detection task was used to reveal the inhibitory and facilitatory aftereffects of the attentional processing of the emotional cues. An emotion-based IOR effect on reaction time was observed only after the presence of a negative emotional cue, implying that the attentional system tends to inhibit irrelevant negative emotion but not inhibit irrelevant positive emotion.
