Patients with defined frontal lobe lesions were assigned to 1 of 2 groups based on whether they showed a behaviorally assessed dysexecutive syndrome or were behaviorally normal. All participants were tested on dual-task performance and on 2 tasks assumed to measure frontal lobe function, the Wisconsin Card Sorting Test and verbal fluency. The dysexecutive group differed significantly from the nondysexecutive in showing impaired capacity for dual-task coordination, but there were no significant differences on the Wisconsin Card Sorting Test and verbal fluency. Results are interpreted in terms of a multicomponent central executive, whose function is linked to, but not coterminous with, the operation of the frontal lobes.
患有明确额叶病变的患者根据其是否表现出经行为评估的执行功能障碍综合征或行为正常被分为两组。所有参与者都接受了双任务表现测试以及两项假定用于测量额叶功能的任务，即威斯康星卡片分类测试和语言流畅性测试。执行功能障碍组在双任务协调能力受损方面与非执行功能障碍组有显著差异，但在威斯康星卡片分类测试和语言流畅性方面没有显著差异。结果依据多成分中央执行系统进行解释，其功能与额叶的运作相关，但并非完全相同。
