Impairments in selective attention have been proposed as an explanation for the source monitoring deficits in schizophrenia. We tested this hypothesis by examining correlations between source monitoring variables and a measure of selective attention (from the Stroop Test) in 54 individuals with schizophrenia subjects and 42 normal controls. We did not find significant correlations between source monitoring measures and selective attention. Selective attention impairments do not explain source monitoring deficits observed in schizophrenia. Source monitoring deficits deserve continued efforts to elucidate their causes and consequences.
