Deficient ability to take advantage of predictable elements in the performance of cognitive tasks has been proposed as an underlying factor for a number of deviances in schizophrenia. In a schizophrenic sample (n=39), we propose and test the view that certain memory and motor anomalies arise because of a compromise in the capacity to take advantage of the redundant (predictable) features of cognitive tasks. Results demonstrate a relationship between reduced capacity to take advantage of predictable features of two different cognitive processing tasks, one verbal memory, and the other motor. Poorer verbal recall on high-redundancy word lists was associated with a reduced ability to produce synchronous finger tapping in response to a high redundancy auditory stimulus, and inversely correlated with formal thought disorder ratings. These relationships, we suggest, reflect a specific and common schizophrenic deficit in the use of redundancies, not attributable to a generalized deficiency in performance. Structural imaging evidence from a subsample of these subjects (n=16) implicates frontal areas as the locus of this cognitive impairment.
