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)
