Question

multiple choice 1 point which statement suggests that the dorsolateral prefrontal cortex is dysfunctional in people with schizophrenia? people with schizophrenia show increased blood flow to this area when they perform the wisconsin card sort task. people with schizophrenia are impaired on tasks requiring memory for a small number of items after a short delay. people with schizophrenia display disturbance in both cognition and memory. people with schizophrenia are impaired on phonological memory tasks.

Explanation:

The dorsolateral prefrontal cortex (DLPFC) is involved in cognitive tasks like the Wisconsin Card Sort. In schizophrenia, DLPFC dysfunction is associated with reduced blood flow during such tasks. So a statement suggesting increased blood flow (implying abnormal function) would indicate DLPFC dysfunction. Other options relate to memory/cognition disturbances but not directly to DLPFC function.

Answer:

The third option (the one with "People with schizophrenia show increased blood flow to this area when they perform the Wisconsin Card Sort task.")
