Monkeys and children show sex differences on tasks that depend on the orbital prefrontal cortex. To determine whether similar sex differences exist across the life span, adults were tested on an orbital-dependent decision-making task, the Iowa Card Task, as well as on a control task, the California Weather Task. In addition, estradiol, progesterone, and testosterone were assayed. The 6 groups of participants were college-age men, older men, young low-hormone (menstruating) women, young high-hormone (midluteal) women, older postmenopausal women on estrogen replacement therapy (ERT), and older postmenopausal women not on ERT. Results showed a male superiority on the Iowa Card Task. Among college-age men there was a negative correlation between performance and testosterone levels. There were no significant differences among groups of women on the card task. There were no significant sex differences or hormone correlations on the California Weather Task.
