Distractibility in schizophrenia

This study examined the effects of neuroleptic medication on the allocation of attentional resources to distracting stimuli in patients with schizophrenia. Twenty-five patients were tested twice (medication-free and after medication stabilization) on the Identical Pairs versions of the Continuous Performance Test under both distraction and no-distraction conditions. Sixteen patients were chronically ill adults and nine patients were young neuroleptic-native patients in the early stages of illness. Results indicated that neuroleptic treatment did not improve distractibility for either group and that both groups were comparably distractible. These findings suggest that medication does not improve the misallocation of attention to distracting stimuli in patients with schizophrenia.
