Abstract

Beat gestures, rhythmic hand movements that co-occur with speech, appear to be uniquely associated with the cerebellum in healthy individuals. This behavior may also have relevance for psychosis-risk youth, a group characterized by cerebellar dysfunction. This study examined beat gesture frequency and postural sway (a sensitive index of cerebellar functioning) in youth at ultrahigh risk (UHR) for psychosis. Results indicated that decreased beat gesture frequency, but not self-regulatory movement, is associated with elevated postural sway, suggesting that beat gestures may be an important biomarker in this critical population.
