Research in the neuropsychology of psychosis has advanced from the identification of differential cognitive deficits in patient groups to theoretical attempts to explain psychotic phenomena in terms of dysfunctional information processing systems. Differing levels of neuropsychological analysis in this area are outlined and a recently proposed theoretical model of the neuropsychology of schizophrenia is presented. Memory dysfuction and frontal lobe' impairments in schizophrenia are also discussed and finally, single-case study approaches, neuropsychological findings in chronic schizophrenia, cognitive analyses of psychotic phenomena and twin research are briefly reviewed.
