This study examined the effects of neuroleptic medication on the alloc
ation of attentional resources to distracting stimuli in patients with
schizophrenia. Twenty-five patients were tested twice (medication-fre
e and after medication stabilization) on the Identical Pairs version o
f the Continuous Performance Test under both distraction and no-distra
ction conditions. Sixteen patients were chronically ill adults and nin
e patients were young neuroleptic-naive patients in the early stages o
f illness. Results indicated that neuroleptic treatment did not improv
e distractibility for either group and that both groups were comparabl
y distractible. These findings suggest that medication does not improv
e the misallocation of attention to distracting stimuli in patients wi
th schizophrenia.
