Summary

People with schizophrenia show disturbances in the perception of time. Among these alterations are the perturbations of the temporal order judgment. They are characterized by the fact that, as opposed to the general population, people with schizophrenia require a longer time interval between two successive stimuli to estimate which of the two events appeared first. If these alterations are now well documented, their consequences remain little explored. Among these consequences could however appear distortions of the judgment of causality (likely to underlie certain delusional interpretations) as well as a distressing experience of loss of the continuity of the lived experience (that could contribute to the alterations basic of self-awareness).

Detailed description

The objective of our work lies in the study of the links between temporal sequencing, subjective perception of time and causality. To carry out this work, the investigators will rely on an experimental paradigm (derived from Michotte's paradigm) which makes it possible to explore the links between temporal sequencing and perception of causality, validated in the normal subject. subjective consequences of these alterations will be explored using a phenomenological-inspired clinical scale (EAWE time-scale items)
