The likelihood that females designate persons of the opposite sex as models more often than do males was investigated. Subjects, 61 boys and 64 girls from the sixth grade, plus 52 males and 83 female college students, indicated which other person, past or present, they would most like to be. Approximately 25% of females designated male models while cross-sex choices by males were negligible, the sex difference being statistically reliable at both age levels. Among children, public school girls made significantly more cross-sex choices than parochial school peers. Results indicated that lack of available female models was not the sole reason for obtained sex differences and that television played an inordinate role in children's choices. (Author)
