Disgust motivates pathogen avoidance. However, pathogens can occupy food or
mates. Thus, disgust may need to inhibit appetitive motivation to serve its
purpose. As predicted, we found that participants wanted to taste food less
and viewed food less after watching a disgusting versus a neutral video. We
also found that disgust reduced viewing of food at a later, voluntary stage
of attention. These findings may shed light on the role of disgust
proneness in eating disorders and sexual dysfunctions.
