Eye movement impairment and schizotypal psychopathology

Abstract

Patients with schizotypal personality disorder demonstrate qualitatively poorer tracking than comparison groups, and the impaired tracking is associated with deficit-like symptoms.

Schizotypy, schizotypic psychopathology, and schizophrenia: Understanding the nature, basis, and manifestation of the schizophrenia spectrum.

“…In terms of eye-tracking dysfunction among individuals with schizotypic psychopathology, such deficits are clearly found among clinically defined schizotypes (e.g., Siever et al, 1994) and psychometrically identified schizotypes (O'Driscoll, Lenzenweger, & Holzman, 1998). Eye-tracking dysfunction has also been found to aggregate in the biological family members of patients with schizophrenia across numerous studies (Levy et al, 1993).…”
