使用巴甫洛夫恐惧调节程序来检查戴兜帽的老鼠对视觉刺激的习得反应的个体发育。这些数据表明，检测视觉事件所需的过程与学习视觉刺激和休克之间关联所需的过程出现了分离。幼崽直到 17 天大时才适应视觉条件刺激 (CS) 和电击非条件刺激 (US)，尽管 15 天大的孩子就能够清楚地察觉到视觉 CS。尽管 15 日龄婴儿未能适应视觉 CS，但当听觉 CS 与电击相结合时，他们成功地适应了。因此，15 日龄儿童未能适应视觉 CS 并不是由于表现缺陷或作为美国人普遍缺乏电击效果。这些数据表明，视觉系统中介导检测的组件和联想学习所需的组件依次成熟。
A Pavlovian fear conditioning procedure was used to examine the ontogeny of the hooded rats' learned responses to visual stimulation. The data suggests a dissociation in the emergence of the processes required to detect visual events and those necessary for learning an association between visual stimulation and shock. Pups did not condition to a visual conditioned stimulus (CS) paired with a shock unconditioned stimulus (US) until they were 17 days old, even though 15-day-olds were clearly able to detect the visual CS. Although 15-day-olds failed to condition to the visual CS, they conditioned successfully when an auditory CS was paired with shock. Thus, the 15-day-olds' failure to condition to the visual CS was not due to a performance deficit or to a general ineffectiveness of shock as an US. These data suggest that the components of the visual system that mediate detection and those required for associative learning mature sequentially.
