The purpose of the study was to conduct two meta-analytic reviews examining cognitive functioning and schizophrenia. The first review examined the literature comparing the cognitive functioning of schizophrenic patients to healthy controls. A second review examined the cognitive functioning within schizophrenic patients, examining the differences between individuals with primarily positive symptomatology and those with primarily negative symptomatology. The first meta-analysis included 19 studies which assessed 861 schizophrenic patients and 858 healthy volunteers overall. The second meta-analysis included 10 studies comparing the cognitive functioning of 1,263 schizophrenics across positive and negative symptoms. Results of the first review indicated that healthy controls performed better than schizophrenics in all areas of neuropsychological functioning. Results of the second meta-analysis indicated that schizophrenics with primarily positive symptomatology performed better in all areas of functioning, with the exception of attention.
