Schizophrenia is marked by a variety of cognitive and biological abnormalities. In the first part of this paper we describe schizophrenic cognitive deficits in three experimental tasks which tap attention and language processing abilities. We also review biological disturbances that have been reported involving the frontal lobes and the mesocortical dopamine system. In the second part of the paper we present three computer models, each of which simulates normal performance in one of the cognitive tasks described initially. These models were developed within the connectionist (or parallel distributed processing) framework. At the behavioral level, the models suggest that a disturbance in the processing of context can account for schizophrenic patterns of performance in both the attention and language-related tasks. At the same time, the models incorporate features of biological computation that address the biological processes underlying cognitive deficits. All three models incorporate a mechanism for processing context that can be identified with frontal lobe function, and a parameter that corresponds to the effects of dopamine on frontal cortex. A disturbance in this parameter is sufficient to account for schizophrenic patterns of performance in all three of the cognitive tasks simulated. Thus, the models offer an explanatory mechanism linking performance deficits to a disturbance in the processing of context which, in turn, is attributed to a reduction of dopaminergic activity in prefrontal cortex. In the General Discussion, we consider the implications of these models for our understanding of both normal and schizophrenic cognition. We conclude with a discussion of some of the general issues surrounding the modelling endeavor itself.

Metacognition is a term that spans many sub-areas in psychology and means different things to different people. A dominant view has been that metacognition involves the monitoring of performance in order to control cognition; however, it seems reasonable that much of this control runs implicitly (i.e., without awareness). Newer still is the field of implicit memory, and it has different connotations to different sub-groups as well. The editor of this volume takes it to mean that a prior experience affects behavior without the individual's appreciation (ability to report) of this influence. Implicit memory and metacognition seem to be at two opposite ends of the spectrum -- one seemingly conscious and control-oriented, the other occurring without subjects' awareness. Do these processes relate to each other in interesting ways, or do they operate independently without reference to each other? The relatively novel conjecture that much of the control of cognition operates at an implicit level sparked Reder's desire to explore the interrelationship between the two fields. Developed within the last two decades, both fields are very new and generate a great deal of excitement and research interest. Hundreds of articles have been written about metacognition and about implicit memory, but little if any material has been published about the two areas in combination. In other words, Metacognition and Implicit Memory is the first book attempting to integrate what should be closely linked efforts in the study of cognitive science.
