Language disorders are frequently comorbid with attention deficit/hyperactivity disorder (ADHD). Sluggish cognitive tempo (SCT), a second attention disorder, may potentially explain some of the links between language disorders and ADHD. In this study we examined the psycholinguistic abilities of 207 children (mean age 7;10) with and without clinically significant levels of SCT symptoms to determine the degree to which symptoms of language disorder co-occur in cases of SCT. Analyses of children's tense-marking, nonword repetition, and sentence recall indicated that deficits in these areas were not associated with SCT. Instead, SCT appears to be more closely aligned with features of social (pragmatic) communication disorder.
语言障碍常与注意力缺陷/多动障碍（ADHD）共病。迟钝的认知节奏（SCT）是第二种注意力障碍，它可能解释了语言障碍与 ADHD 之间的一些联系。在这项研究中，我们检查了 207 名有和没有临床显著 SCT 症状的儿童的心理语言学能力，以确定 SCT 病例中语言障碍症状的共病程度。对儿童的时态标记、非词重复和句子回忆的分析表明，这些领域的缺陷与 SCT 无关。相反，SCT 似乎更接近社会（语用）交流障碍的特征。
