Sluggish cognitive tempo (SCT) is a controversial clinical designation that some regard as a subtype of ADHD, others as a separate but related disorder, and still others as a set of commonly shared problems across different disorders. In this study, we examined the degree that SCT symptoms of underactivity, confusion, and day dreaminess characterize children with Specific Language Impairment (SLI) and/or other types of Developmental Language Disorder (DLD). A battery of psycholinguistic, cognitive, and socioemotional behavioral indices was administered to 216 children (age range: 6;0 to 10;3) with either confirmed DLD status (n = 56) or typical language (TL) skills (n = 160). Both the DLD and TL groups consisted of subgroups of children with and without nonverbal impairments. Results indicated that the presence of nonverbal impairments rather than language impairments in children’s profiles were associated with elevations in parent reported SCT symptoms.
