Attention Deficit and Hyperactivity Disorder is an important problem especially at schools in terms of learning, social relationships and adaptation. The main purpose of this study is to investigate the internal processes of a child diagnosed with Attention Deficit and Hyperactivity disorder through projective tests. For this purpose, projective tests, Rorschach and CAT, were applied to a seven-year-old boy. The responses of the subject were evaluated in terms of psychic processes, emotional reactions, drive control and social adjustment through a psychoanalytical perspective. In addition, the effects of parents? relationship with their own parents on the child adjustment problem were discussed. As a result of the evaluation, findings such as uncontrollable impulsivity, low ego control, emotional suffocation and the lack of paternal function and maternal containing function were obtained. This indicates the existence of an underlying problem relating to internalized objects: lack of parental support and loss anxiety.
