ABSTRACT
This chapter represents one instance of that behavior. It argues that rehabilitation can be informed by, as well as inform, models of cognitive processes, and indeed that this is beginning to occur. It is still a rare event, and even more rarely is it a properly designed and executed event; but there are grounds for cautious optimism. Most of the models currently popular in cognitive neuropsychology, although differing from one another in various ways, share certain common features. The major similarity is the assumption of modularity, namely that within a domain like language processing, there are a number of separable subcomponents responsible for different aspects of processing. Proper analysis of an aphasic patient's difficulties in terms of an information processing model should allow the therapist to decide the underlying cause(s) of a patient's problem. From the patient's point of view, improvement that applies to multiple modalities and tasks is of course that most desirable outcome.
