一个计算机模型，执行4个任务，有时受损的额叶损伤：电机排序，Stroop任务，威斯康星州卡片分类测试，和上下文记忆任务。在每项任务中，典型的额叶损伤患者的表现模式显示出相同类型的损害模型的结果，具体地说，削弱工作记忆中的元素之间的关联。该模拟显示了单一潜在类型的损伤如何导致各种看似不同的任务受损。此外，假设的损害影响执行任务的处理组件，而不是一个独特的中央执行。
A computer model is presented that performs 4 tasks sometimes impaired by frontal damage: motor sequencing, the Stroop task, the Wisconsin Card Sorting Test, and a context memory task. In each task, patterns of performance typical of frontal-damaged patients are shown to result from the same type of damage to the model, specifically, weakening of associations among elements in working memory. The simulation shows how a single underlying type of damage could result in impairments on a variety of seemingly distinct tasks. Furthermore, the hypothesized damage affects the processing components that carry out the task rather than a distinct central executive.
