临床研究表明，额叶损伤可能导致一系列症状，统称为“执行障碍综合征”，其特征是情绪、个性、动机、行为和认知方面的变化。因子分析研究使用问卷测量日常生活中的执行障碍问题也表明了神经系统疾病患者的执行障碍综合征的分馏。到目前为止，很少有研究来探讨非临床人群日常生活中执行问题的基本发生率。这项试点研究旨在探索类似于非临床样本报告的执行障碍综合征的执行障碍行为。总共招募了93名假定正常的参与者。执行功能障碍问卷和一套执行功能的临床测试管理的所有参与者。一个5因素的解决方案非常类似于以前的研究：抑制（因素1），意向性（因素2），知行分离（因素3），在阻力（因素4），和社会调节（因素5）。执行功能的衍生因素和测试之间建立了相关性。这项研究提供了经验证据，表明非临床样本在日常生活中可能会遇到类似的执行障碍行为。在非临床样本之间的执行系统的分馏的问题也将被讨论。
Clinical studies indicate that damage to the frontal lobes may lead to a set of symptoms collectively known as 'Dysexecutive syndrome', which is characterized by changes in emotion, personality, motivation, behaviour and cognitive aspects. Factor analytical study using questionnaires measuring dysexecutive problems in everyday life also suggests a fractionation of the dysexecutive syndrome among patients with neurological disorders. As yet, very little research has been conducted to explore the base-rate of executive problems in everyday life among the non-clinical population. This pilot study aimed to explore dysexecutive behaviour similar to that of dysexecutive syndrome reported by a non-clinical sample. A total of 93 presumably normal participants were recruited. The Dysexecutive Questionnaire and a set of clinical tests of executive function were administered to all the participants. A 5-factor solution very similar to that of a previous study was derived: inhibition (factor 1), intentionality (factor 2), knowing-doing dissociation (factor 3), in-resistance (factor 4), and social regulation (factor 5). Correlation was established among the derived factors and tests of executive function. This study provides empirical evidence that a non-clinical sample may encounter similar dysexecutive behaviours in daily life. The issue of the fractionation of the executive system among the non-clinical sample will also be discussed.
