Abstract: Cognitive sex differences among adults have been consistently acknowledged in the scientific literature. Males typically perform better than females on various tests of spatial abilities. Females typically perform better than males on tests of fine motor dexterity, object and location memory tasks, and tests of verbal fluency. However, data have shown that these sex differences typically do not appear before puberty. There is compelling evidence from adult studies that at least some of these sex specific behaviors are correlated with levels of circulating testosterone, estradiol, and progesterone. The present study is in the 4th year of a longitudinal study in which adolescents were tested in their 7th, 8th, 9th, and now 10th grade years. Adolescents completed six cognitive tasks that have shown sex differences in adults. Performance on these tasks was correlated with circulating levels of estradiol, progesterone, and testosterone and compared with performance in the previous three years.
