The Iowa Gambling Task (IGT; Bechara, Damasio, Damasio, & Anderson, 1994) was investigated in relation to fluid intelligence and two conventional executive function tasks: letter fluency and the Wisconsin Card Sorting Test. Fifty-one children aged 8-10 years and a heterogeneous group of 40 adults served as participants. Adults outperformed children on all measures except one; this was the number of good cards selected in the IGT. Intercorrelations among executive function tasks were low. The number of good cards in the IGT appeared to be lower than in previous studies. Reasons for poor performance are discussed. The IGT may possess some shortcomings, which should be investigated in future studies. In clinical usage, the IGT may best serve as a complementary tool to the executive functions test battery.
爱荷华赌博任务（IGT；贝沙拉、达马西奥、达马西奥和安德森，1994年）与流体智力以及两项传统执行功能任务（字母流畅性和威斯康星卡片分类测验）相关联进行了研究。51名8至10岁的儿童和40名组成各异的成年人作为参与者。除了一项指标外，成年人在所有测量指标上的表现均优于儿童；这一指标是IGT中选择的好牌数量。执行功能任务之间的相互关联较低。IGT中的好牌数量似乎低于先前的研究。讨论了表现不佳的原因。IGT可能存在一些缺点，未来的研究应予以调查。在临床应用中，IGT最好作为执行功能测试组套的补充工具。
