The relationship between early sexual maturation and the psychosexual behaviors of dating and sexual intercourse was investigated using a national sample of adolescent females aged 15 to 19. Among both black and nonblack subjects, early-maturing girls were more likely to have experienced earlier dating and coital onset than were their later-maturing peers. Blacks experienced menarche and first intercourse at earlier ages, yet dating onset at later ages. Early menarche was also associated with marriage at an early age for nonblacks, but not for blacks. These racial differences were explained in terms of diverse socialization patterns or cultural expectations. For both blacks and nonblacks, those with earlier coital experience were found to have had menarche and dating onset at earlier ages.
利用一个全国性的15至19岁青春期女性样本，对性早熟与约会和性交等性心理行为之间的关系进行了调查。在黑人与非黑人受试者中，早熟女孩比晚熟同龄人更有可能更早开始约会和发生性行为。黑人初潮和首次性交的年龄更早，但开始约会的年龄较晚。初潮早也与非黑人的早婚有关，但与黑人无关。这些种族差异可以从不同的社会化模式或文化期望方面来解释。对于黑人和非黑人来说，那些有过早性经历的人初潮和开始约会的年龄都更早。
