This study investigated children's sex biased attitudes as a function of the sex, age, and race of the child as well as a geographical-SES factor. Two attitudes were measured on a 55-item questionnaire: Sex Pride (attributing positive characteristics to a child of the same sex) and Sex Prejudice (attributing negative characteristics to a child of the other sex). Subjects were 1,169 children (513 black, 656 white) in grades 2 and 5, who were taken from either a lower-middle, upper-lower class urban or a suburban community. Gender was divided fairly equally. The children were tested in their schools, with examiner race varying equally at each grade level. Results indicated that all children tended to select children of the same sex for the positive attributes, but that both boys and girls selected boys for the negative attributes. Although all Sex Pride scores decreased with age, this was most exaggerated for the girls from a lower-middle, upper-lower class urban environment. (Author/SB)
