猴子和儿童在依赖眼眶前额叶皮质的任务上表现出性别差异。为了确定成年人的一生中是否存在类似的性别差异，他们在依赖轨道的决策任务爱荷华州卡片任务和控制任务加州天气任务上进行了测试。此外，还测定了雌二醇、孕酮和睾酮。这6组参与者分别是大学年龄的男性、老年男性、年轻的低激素(月经)女性、年轻的高激素(黄体中期)女性、接受雌激素替代治疗(ERT)的老年绝经后女性和没有接受ERT治疗的老年绝经后女性。结果显示，在爱荷华州卡片任务中，男性占优势。在大学年龄的男性中，表现与睾丸激素水平呈负相关。在卡片任务中，女性群体之间没有显著差异。在加州天气任务中，没有显著的性别差异或激素相关性。
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.
