ABSTRACT
College students were placed in 2 groups, hallucinators and nonhallucinators, 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 hallucinators were instructed to attend to the left ear stimuli (forced-left condition), 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 maintained a right ear advantage. Results suggest that auditory hallucinations in college students are associated with differences in hemispheric functioning.

The ability of 40 college students to discriminate the number of tactile stimuli presented simultaneously was measured in two experiments. Simulation was provided by 12 solenoids fixed to points on the arms and legs. Exp. I showed a mean correct discrimination level of between 1.55 and 2.10 solenoids. Exp II compared discrimination of numerosity by a group who received immediate feedback with a no-feedback control group. Feedback produced a small increase in this ability. However, the most stimulation points correctly discriminated did not exceed three. The data are discussed in terms of the possible role of cutaneous masking.
