Hierarchical analysis of the sense of agency in schizophrenia: motor control, control detection, and self-attribution.

ABSTRACT: The sense of agency refers to the feeling of initiating and controlling one's actions and their resulting effects on the external environment. Previous studies have uncovered behavioral evidence of excessive self-attribution and, conversely, a reduction in the sense of agency in patients with schizophrenia. We hypothesize that this apparent paradox is likely to result from impairment in lower-level processes underlying the sense of agency, combined with a higher-level compensational bias. The present study employed three behavioral tasks utilizing the same stimuli and experimental design to systematically evaluate multiple factors that influence the sense of agency, including motor control, sensorimotor processing, and self-attribution. Participants' real-time mouse movements were combined
