In this article, we present data on the analysis of maze-solving behavior as a tool for the investigation of cognitive disturbance in schizophrenic patients. Solving maze tasks efficiently requires both an interaction between and an integration of perceptive and action-oriented processes. Starting from the hypothesis that these domains are preferentially disturbed in schizophrenia, we propose that the maze-solving behavior of schizophrenic patients permits insight into specific impairments in disease-related cognitive processing. We present the results of a maze task study comparing medication-free schizophrenic patients and matched healthy controls. This analysis forms the basis for an investigation of the influence of psychopharmacological treatment strategies on the observed behavior in the maze-solving paradigm. Finally, a third study concerned with improvement over time associated with medication is presented, and possible influences of extrapyramidal motor disturbances on schizophrenic patients' maze performance are discussed.
