psychoanalytic play technique

a method of child analysis developed by Melanie Klein during the 1920s, in which play activity is interpreted as symbolic of underlying fantasies and conflicts and substitutes for free association. The therapist provides toys for the child and encourages free, imaginative play in order to reveal the child’s unconscious wishes and conflicts.
