Psycholinguistic profiling of children with sluggish cognitive tempo.

PMID 35748339WHAT IT FOUND
Children with elevated sluggish cognitive tempo symptoms showed weaker pragmatic language and working memory compared to peers.
However, they did not show the core grammar and word repetition deficits typical of developmental language disorder. This suggests SCT and DLD require different assessment approaches.
Key findings
01Children with elevated SCT symptoms showed significantly weaker pragmatic abilities and working memory compared to the comparison group.
02The study found little support for the idea that children with elevated SCT symptoms share the core clinical markers of specific language impairment, such as tense-marking and nonword repetition deficits.

What it does not show
The study relied on a four-item checklist to identify sluggish cognitive tempo symptoms, which may not have captured all important secondary symptoms. The comparison group included children with typical development as well as those with ADHD and language disorders, which may dilute group differences. There was potential overlap between the items used to measure pragmatic abilities and the symptoms of sluggish cognitive tempo, making it difficult to separate the two constructs. The study was cross-sectional, so it cannot determine whether language difficulties contribute to or result from sluggish cognitive tempo symptoms.
Declared interests
The research was supported by the National Institutes of Health (Extramural).
The easy way to misread this
Do not assume that children with sluggish cognitive tempo symptoms have developmental language disorder, as they did not show the core grammar and word repetition deficits typical of DLD. Instead, clinicians should expect weaknesses in social communication and working memory.
