28.3 MINIMAL SELF IN SCHIZOPHRENIA: THE TIME PERSPECTIVE
April 1, 2018 Patrick Poncelet, Franck, Nicolas, Martin, B. (Brice) et al.
Stabilized patients with schizophrenia can expect well-learned sensory signals and react to unusual events to some extent, but those who report feeling not immersed in the world (a measure of minimal self disorders) do not benefit from the passage of time to react faster. In a motor task, patients' feeling of control drops as soon as an imperceptible delay is introduced in haptic feedback, whereas controls tolerate such delays. Patients also have difficulty adjusting sensory anticipation when feedback is delayed. The results suggest a link between disrupted time expectation and minimal self disorders; fragile time expectations may contribute to a sense of discontinuity that disrupts bodily signals and the sense of self.
