Reasoning and problem solving in the spatial domain are important aspects of executive function that are reliably impaired in schizophrenia, and the Groton Maze Learning Test(c) (GMLT) provides a valid measure of spatial working memory. In the current study, 34 patients with first-episode schizophrenia and 20 matched controls were assessed for baseline spatial working memory abilities using this hidden maze learning test. Approximately one month after baseline assessment, allowing for symptoms to stabilize in response to treatment with therapeutic doses of atypical antipsychotic medications for individuals with schizophrenia, all participants were again assessed with the GMLT. Prior to pharm..
