Orality and latency of volunteering to serve as experimental subjects

A comparison was made of the oral content of Rorschach scores of male Introductory Psychology students who signed up for experiments in the first half of the semester with those who did not sign up until the second half of the semester. Those who participated early in the semester saw more oral images than those who waited until late in the semester to participate (p = .02). The implications of this finding are discussed.
