Continuous Performance Tests (CPTs) are known to measure inattention and impulsivity in students with ADHD. Many CPTs utilize a visual format. It is accepted that auditory tasks reflect attentional demand more closely in the classroom. Thus, the association between deficits found by auditory and visual CPTs needs to be studied. We hypothesized that impulsivity would be dependent on sensory modality and inattention would be a unitary cross-modal construct.
Forty-four students with ADHD performed two CPTs (visual and auditory). We analyzed correlations between the variables examined by the two tasks.
There were strong correlations between variables measuring inattention. Correlations between auditory and visual measures of impulsivity were weak.
Inattention is partially independent of modality. In contrast, response inhibition is modality-specific. Although ADHD is defined regardless of modality, hyperactive students may exhibit deficits in the auditory modality but not in the visual modality or vice versa.
连续性能测试（CPTs）被认为可以测量 ADHD 学生的注意力不集中和冲动。许多 CPT 采用视觉格式。人们普遍认为，听觉任务在课堂上更能反映注意力需求。因此，需要研究听觉和视觉 CPT 发现的缺陷之间的关联。我们假设冲动性将取决于感觉模态，而注意力不集中将是一种跨模态的单一结构。
44 名 ADHD 学生进行了两项 CPT（视觉和听觉）。我们分析了两个任务所检查的变量之间的相关性。
注意力不集中的变量之间存在很强的相关性。听觉和视觉冲动性测量之间的相关性较弱。
注意力不集中部分独立于模态。相比之下，反应抑制是模态特异性的。尽管 ADHD 是不分模态定义的，但多动的学生可能在听觉模态中表现出缺陷，而在视觉模态中没有，反之亦然。
