Extra Version, Neuroticism and the Volunteer Subject

Abstract

Personality differences in volunteering for experiments were studied in 231 college students. The Eysenck Personality Inventory was used to measure extraversion and neuroticism. Ss were asked to volunteer for four experiments: general, boring, social, or shock experiment. Ss who volunteered for the general and social experiments were significantly more extraverted, while the high neuroticism-extraverts volunteered significantly more for the shock experiment.
