在心理活动期间任务诱发的瞳孔扩张的幅度先前已被证明是在心理任务的性能中使用的认知能力的指标。为了确定“智力”和能力需求之间的关系在心理活动中，任务诱发的瞳孔扩张进行了测量，而两组大学生在他们的成绩不同的学业能力倾向测试解决心算问题。在三个问题难度水平上，更聪明的受试者表现出的任务诱发的瞳孔扩张比他们不太聪明的同行要小。因此，越聪明的人似乎拥有更有效的信息处理认知结构。这些数据提供的证据表明，不同心理测量智能的个体之间的生理差异出现在心理活动。
The magnitude of task-evoked pupillary dilations during mental activity has previously been shown to index the cognitive capacity utilized in the performance of the mental task. To determine the relation between "intelligence" and capacity demands during mental activity, task-evoked pupillary dilations were measured while two groups of university students differing in their scores on the Scholastic Aptitude Test solved mental arithmetic problems. Over three levels of problem difficulty, more intelligent subjects showed smaller task-evoked pupillary dilations than did their less intelligent counterparts. Thus, the more intelligent appear to possess more efficient cognitive structures of information processing. These data provide evidence that physiological differences between individuals of differing psychometric intelligence emerge during mental activity.
