背景：选择性注意是否是儿童注意缺陷多动障碍（ADHD）的主要缺陷仍存在争议。研究方法：我们使用知觉负荷范式来检查儿童的早期和晚期选择性注意与原发性注意力不集中（ADHD-I）和混合亚型（ADHD-C）的ADHD。结果如下：没有证据表明这两种亚型中存在选择性注意力缺陷，但缓慢的认知克里思与异常的早期选择有关。结论：至少有一部分，可能是大多数，患有DSM-IV ADHD的儿童具有正常的选择性注意力。结果支持远离注意力功能障碍作为ADHD-C的主要理论。在ADHD-I中，这是第一个正式的后注意力网络功能障碍测试，结果并不支持这一理论。然而，ADHD儿童的认知克里思（SCT）缓慢，需要更多的研究可能早期选择性注意缺陷。
Background: Whether selective attention is a primary deficit in childhood Attention Deficit Hyperactivity Disorder (ADHD) remains in active debate. Methods: We used the perceptual load paradigm to examine both early and late selective attention in children with the Primarily Inattentive (ADHD-I) and Combined subtypes (ADHD-C) of ADHD. Results: No evidence emerged for selective attention deficits in either of the subtypes, but sluggish cognitive tempo was associated with abnormal early selection. Conclusions: At least some, and possibly most, children with DSM-IV ADHD have normal selective attention. Results support the move away from theories of attention dysfunction as primary in ADHD-C. In ADHD-I, this was one of the first formal tests of posterior attention network dysfunction, and results did not support that theory. However, ADHD children with sluggish cognitive tempo (SCT) warrant more study for possible early selective attention deficits.
