Playing tennis is a mind-body experience, but it is also the reverse—a body-mind experience in which the body informs what the mind does not yet know. The body encodes and draws on its own procedural memories and encodes them in a way that sometimes gives the body a “mind of its own.” Some tennis players are able to regulate their emotions while performing demanding competitive feats, whereas others become affectively dysregulated, dissociated, even proverbial “head cases.” Can our understanding of affect regulation, self-states, dissociation, body performance, and analytic supervision be couched on the court—a place where tennis and psychoanalysis meet at the net?
