The E.P.I. was administered to 58 normal S s who were students in three adult psychology classes. Immediately after responding to the E.P.I., S s were asked to rate themselves on a seven‐point introversion‐extraversion scale. The S s were divided into Introverts and Extraverts on the basis of their self‐ratings. The S s were also dichotomized into Introverts and Extraverts on the basis of E scores. Introvert and Extravert criterion groups were found to be significantly different from each other and from the total group. The results indicate that introverts as defined by self‐ratings are somewhat more aware of their position on the Introversion‐Extraversion continuum than are extraverts. Results support the validity of the E scale of the E.P.I. when using Introvert and Extravert criterion groups as defined above.
