Abstract

Individuals with 22q11.2 deletion syndrome (22q11DS) show high rates of anxiety associated with their increased risk of developing schizophrenia. Biased attention is associated with anxiety and is important to investigate in those with 22q11DS given this association. We analyzed attention bias to emotional faces in 7- to 17-year olds with 22q11DS and typically developing controls (TD) using a dot probe threat bias paradigm. We measured response time, eye tracking, and pupilometry. Those with 22q11DS showed no significant changes in early versus late trials, whereas those who were TD showed differing patterns in both gaze and pupilometry over time. The patterns in those who are TD may indicate adaptation that is lacking or slower in individuals with 22q11DS.
