The study examined the actual speech tempos of extraverts and introverts and stereotyped notions about the tempos of extraverts and introverts. Forty-six female undergraduates were divided on the basis of the Eysenck Extraversion Scale into equal groups of extraverts and introverts. Each was asked to talk in a natural manner about $$ TAT pictures, to talk as if she were an extravert or an introvert, and to speak rapidly or slowly. The results indicate that the actual speech tempo of extraverts is faster than that of introverts and suggest that the stereotypes of the speech rates of extraverts and introverts somewhat exaggerate their actual rates.
