College students were placed in 2 groups, hallucinators and nonhallucinator
s, on the basis of their responses to a verbal hallucinations questionnaire
. Both groups were given a consonant-vowel version of a Dichotic Listening
Test under 3 conditions: nonforced, forced-right, and forced-left. When hal
lucinators were instructed to attend to the left ear stimuli (forced-left c
ondition), they had fewer correct responses to right ear syllables than did
nonhallucinators. This resulted in a left ear advantage for hallucinators.
When nonhallucinators were instructed to attend to the left ear, they main
tained a right ear advantage. Results suggest that auditory hallucinations
in college students are associated with differences in hemispheric function
ing.
