Meaningfulness and global-local processing in schizophrenia

Abstract : The present work aimed to study the influence of the meaningfulness of stimuli during global-local processing in schizophrenia. Study participants were asked to determine whether pairs of compound stimuli (global forms composed of local forms) were identical or not. Both global and local forms represented either objects or non-objects. Results indicated that when identification processes were useful for performing the task, similar global-local response patterns were observed in patients and controls. However, patients were more affected than controls when an object was present at a distractor level, particularly when this information came from the local level. These results are discussed in terms of the conjunction of executive and visuospatial deficits and underscore the importance of meaningful identification in the visual perception of schizophrenia patients, given its central role in day-today situations.
