The theoretical formulations of analysis understate the communicative aspects of human behavior and the communicative and evocative nature of affects. Structural and economic aspects of psychic life are stressed at the expense of the communicative. The analyst's objective and explicit verbal interpretations always contain implicit communications; these Rycroft believes to be the major cause of therapeutic movement. The implied ideas convey the analyst's concern for the patient and the reassurances that enable the patient to be himself, to grow, and to have a relationship without violation of his personality and his intrinsic capacity for growth.
