Personality characteristics were assessed for 65 male and 85 female gifted adolescents and their parents. Ss were enrolled in a college program for gifted students. The Myers-Briggs Type Indicator and the Adjective Checklist were used to describe personality patterns found in this group and to compare the gifted student to other populations. A set of personality characteristics that differed from other adolescent groups was found for the gifted students, although a diversity of types was found in the gifted population. Although the sexes were very similar in personality type, they differed in whether they preferred an interpersonal (females) versus an impersonal (males) orientation. Striking differences were found between personality preferences found for the gifted and those expressed by their parents. Personality was related to achievement for only the boys, with extroverted, thinking, judging types receiving higher grades in the college seminars. (Author/CL)
