The purpose of this study was to investigate whether, when both listener and speaker are unknown to one another, listeners of each sex do or do not tend to differentially evaluate presentations by speakers according to sex; results were then compared to those of earlier studies in which the women being judged were hypothetical authors. A group of 502 male and female students in undergraduate public speaking classes were asked to evaluate presentations by male and female communicators as a regular aspect of the course. Results indicated that students demonstrate no prejudice toward communicators of either sex, even when the communicators are personally unknown, suggesting that stereotypes relied on for judgments of source play a lesser role when a real woman is the message source because other information is available to use in judging the individual. Comparison to earlier studies shows that judgments about the performance of females differ considerably depending on whether the women being judged are real or hypothetical; earlier generalizations that women are in general prejudiced against other women appear to be unfounded.
