Controlling the spotlight of attention: Visual span size and flexibility in schizophrenia

► We measure visual span size among patients with schizophrenia. ► We measure how patients' visual span size changes as a function of task demands. ► We use eye-tracking and the gaze-contingent window paradigm to measure visual span. ► Patients demonstrate smaller visual span sizes on some search conditions. ► Patients do not flexibly modulate their visual span as a function of task demands.
