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.
