Fragile temporal prediction in patients with schizophrenia is related to minimal self disorders

People with schizophrenia struggle to predict when events will happen based on elapsed time, and this difficulty relates to disturbances in the sense of self. In a study of 28 patients and 24 matched controls, participants viewed a visual cue that either predicted or did not predict when a target would appear (after 400 ms or 1000 ms). Both groups responded faster to targets after longer intervals due to the natural predictability of time passing (the hazard function). However, patients with high scores on the EASE scale for self-awareness and presence showed no benefit from this temporal predictability, while those with low scores did.
