The Schema Model and the Structural Model
In formulating the structural model, A. Freud explained that he had discarded the topographic model for two reasons. The first problem he had with the topographic model was the circumstance that the defenses of the ego were regularly unconscious. The second reason Freud gave for abandoning the topographic model was his recognition that the feeling of guilt and the need for punishment may also be unconscious. The concept of the repressed or dynamic unconscious has no clear, generally accepted relationship to the structural model. In spite of their central role in the structure of neuroses and in spite of the necessity for understanding them in the conduct of analyses, these schemas are not components of the basic model of the mind in current psychoanalytic theory, that is, the structural model. Schemas, are neither lifeless classifications nor reified metapsychological abstractions.
