In the previous chapters we discussed neurosogenesis and reviewed the use of the concept of the schema. We showed how this concept is far from new and how it was simultaneously but separately developed by both psychoanalysts and cognitive psychologists. In this chapter we present and discuss the schema model as it is applied in psychodynamic practice. In advancing this model, we include some concepts associated with earlier models of the mind. In particular, we borrow from the work of Piaget to explain how certain organized memories and fantasies remain sequestered from the main mass of ideas or ego. As we discuss this model, it will be necessary to stipulate some terminology and perhaps justify it. This model has relatively few concepts; nonetheless, we believe it provides a valid framework with which one can organize and deal clinically with psychopathology in its considerable complexity.
