Are You Looking or Looking Away? Visual Exploration and Avoidance of Disgust- and Fear-Stimuli: An Eye-Tracking Study

The present eye-tracking study investigates whether individuals with different levels of contamination fear are more likely to focus their attention on disgusting stimuli to explore them or to pull their attention away to avoid them. Ninety-two nonclinical participants with varying degrees of contamination fear performed a dot probe task. Eye-tracking methodology was employed to record gaze patterns during the task. In each trial participants looked at two pictures (disgust-neutral, fear-neutral, or neutral-neutral). Participants were further asked about the contents of the picture and the confidence of their answer. The results show that reaction times were slower and fixations were longer and more frequent for disgust targets compared with fear and neutral targets, which was further amplified in individuals with high contamination fear. However, image details of disgusting pictures were remembered less correctly than details of fearful pictures. These findings confirm the idea that attention on disgusting stimuli is maintained. Further, the findings indicate that disgust is processed more superficially and might also be related to disgust-associated uncertainty and ambiguity. The results may help to understand the difficult-to-change nature of disgust, which could be relevant to habituation and extinction processes in exposure therapy.
