The study of perception, according to Gibson, helps us to clarify the extraordinary emotional states which play a part in the process of therapy. From this point of view, affordances concern the interactions between human beings. They can be seen in psychogeriatric wards, where it will be shown that certain practices may break the affordance and asphyxiate the most vulnerable people. The affordance, from a relationship point of view, appears as vital as breathing. In this sense, the hypothesis of a connection between “something psychological” on the one hand, and “something corporeal” on the other, enables the extraction of the body from the role of the thing itself, the noumenon, to make emotion an intermediary conductor. This phenomenon will be examined in the modifications of body image in a relational situation. The observed transformations will thus appear as the narrative of the history of the subject’s body within the group. This history will be “objectivized” by the clinical details that expose the relationships with others as being inseparable from life itself.
