44 first and 46 third graders' perceptions of the competence of boys and girls was assessed. Using a three-point scale, subjects indicated how well they thought either a boy or a girl was performing a variety of activities previously classified as masculine, feminine, or neutral. The data indicated that the 59 boys and 39 girls tended to perceive the child performing the sex-appropriate activity as the more competent. In regard to neutral activities, boys showed a belief in the greater competence of males whereas girls indicated no sex differentiation in their perceptions.
