Attentional processing of information related to illness: Biases and associations with emotional response in young adults with different levels of illness anxiety

Abstract

This study investigated attentional processing of illness-related information and associations with emotional reactivity. 100 young adults with low to high illness anxiety levels underwent free and cued viewing tasks, while eye-tracking and emotional reactivity were recorded. During free viewing, participants showed early orienting bias and sustained vigilance bias toward illness vs neutral pictures. Increased illness anxiety predicted vigilance bias to illness vs fearful pictures. During cued viewing, participants showed avoidance bias for illness vs neutral pictures, predicted by greater cardiac acceleration. Task nature appears to influence attentional processing patterns of illness stimuli. Preliminary evidence supports that attention allocation may be an emotion regulation mechanism.
