| Abstract: | As part of a longitudinal study of the sociosexual development of black preadolescents, sexual maturation and sociosexual behaviors were assessed and the relationships between these variables determined in a sample of 101 nine- to eleven-year-old middle- and low-income boys and girls. Sexual maturation was measured by Tanner's staging criteria of specific secondary sex characteristics. Involvement in heterosexual behaviors was elicited via self reports and was classified on a five-point heterosexual physical activity scale (HPA). The data corroborate other studies in demonstrating that girls were more advanced than boys in the process of sexual maturation. Considerable variation in stages of maturation for chronological age existed in both boys and girls, but was more pronounced for girls. In girls, there was no significant association between HPA and degree of biologic maturation. However, genital development in boys was significantly related to their sexual behavior. Income level was not significantly associated with the HPA score. A baseline from which to chart the progress of sociosexual behaviors in these developing preadolescents was established. |
