Attention deficit/hyperactivity disorder (ADHD) is frequently characterized as a disorder of executive function (EF). However, behavioral tests of EF, such as go/No-go tasks, often fail to grasp the deficiency in EF revealed by questionnaire-based measures. This inability is usually attributed to questionnaires and behavioral tasks assessing different constructs of EFs. We propose an additional explanation for this discrepancy. We hypothesize that this problem stems from the lack of assessment of decision-making (e.g., continuous monitoring of motor behavior such as velocity and acceleration in choice reaching) in classical versions of behavioral tasks. We test this hypothesis by introducing dynamic assessment in the form of mouse motion in a go/No-go task. Our results indicate that, among healthy college students, self-report measures of ADHD symptoms become strongly associated with performance in behavioral tasks when continuous assessment (e.g., acceleration in the mouse-cursor motion) is introduced.
注意力缺陷多动障碍（ADHD）通常被描述为一种执行功能（EF）障碍。然而，执行功能的行为测试，如停止信号任务，往往无法捕捉到基于问卷测量所揭示的执行功能缺陷。这种无能为力通常归因于问卷和行为任务评估的是执行功能的不同结构。我们对这种差异提出了另一种解释。我们假设这个问题源于经典行为任务版本中缺乏对决策的评估（例如，在选择到达时对运动行为如速度和加速度的持续监测）。我们通过在停止信号任务中引入以鼠标运动形式的动态评估来检验这一假设。我们的结果表明，在健康大学生中，当引入持续评估（例如，鼠标光标运动中的加速度）时，ADHD症状的自我报告测量与行为任务中的表现密切相关。
