两个患有注意力缺陷/多动障碍（adhd -合并型和adhd -注意力不集中型）的学龄男孩样本和一个非adhd对照组进行了“AX”版本的连续表现任务（CPT），以检查特定的持续注意力缺陷。三个水平的任务时间被纳入研究表现下降，三个间刺激间隔被纳入检查警觉性缺陷。正如R.A. Barkley和H. C. Quay的行为抑制缺陷模型（R.A. Barkley, 1997； H. C. Quay, 1997）所预测的那样，adhd -合并型（ADHD-C）参与者的表现比其他样本恶化得更快。在注意力不集中（ADHD-IA）的样本中没有发现明显的警觉性缺陷的证据。这些发现表明，当CPT用于诊断评估时，两种ADHD亚型的不同标准可能是有根据的，并且持续的注意力相关的表现下降可能仅是ADHD- c型的典型特征。
Two samples of school-age boys with attention-deficit/hyperactivity disorder (ADHD-Combined and ADHD-Inattentive Types) and a non-ADHD control group were administered an "AX" version of the continuous performance task (CPT) to examine specific sustained attention deficits. Three levels of time-on-task were included to study performance declines, and 3 interstimulus intervals were included to examine vigilance deficits. As predicted by R. A. Barkley's and H. C. Quay's behavior inhibition deficit models (R.A. Barkley, 1997; H. C. Quay, 1997), the performance of the ADHD-Combined Type (ADHD-C) participants deteriorated more quickly than the other samples. No significant evidence of vigilance deficits among the inattentive (ADHD-IA) sample was found. These findings suggest that distinct criteria for the two ADHD subtypes may be warranted when the CPT is used for diagnostic assessment, and sustained attention-related declines in performance may be typical of the ADHD-C Type only.
