Purpose: Many children with developmental language disorder (DLD) have weaknesses in executive functioning (EF), specifically in tasks testing interference control and working memory. It is unknown how EF develops in children with DLD, if EF abilities are related to DLD severity and persistence, and if EF weaknesses expand to selective attention.…

Behavioural self-regulation was assessed using parental and preschool teacher questionnaires. Cognitive abilities (i.e., language, inhibition, planning and fluency, and memory) were assessed with neurocognitive tests,…

The present study examined the psychometric properties of scores from a direct measure of behavioral regulation, the Head-Toes-Knees-Shoulders task (HTKS) with 3- to 6-year-old children in the United States, Taiwan, South Korea, and China. Specifically, we investigated (a) the nature and variability of HTKS scores, including relations to…
