Short-term memory (STM) challenges are often observed in children with Down syndrome (DS), but existing early STM measures introduce measurement confounds in this population. To address the need for valid early STM measures for future DS interventions, this study evaluated the psychometric properties of a modified Corsi Span task, administered to…

The NIH Toolbox Cognition Battery (NIHTB-CB) was developed for epidemiological and longitudinal studies across a wide age span. Such a tool may be useful for intervention trials in conditions characterized by intellectual disability (ID), such as Williams syndrome (WS). Three NIHTB-CB tasks, including two executive functioning (Flanker,…

The purpose of this study was to examine the promise and feasibility of a newly developed curriculum to teach early literacy skills to students with intellectual disability (ID) and students with low IQs. The curriculum texts were written to include familiar settings, high frequency words, natural syntax, and cumulative practice. A single-case…

Physical activity (PA) rates of adolescents with intellectual and developmental disabilities (IDD) are low and effective strategies for increasing PA are limited. The purpose of this study was to assess the feasibility of a group-based PA intervention that was delivered remotely to adolescents with IDD. Participants attended 30-min group PA…

The purpose of this study was to evaluate the feasibility of an intervention focused on improving personal narrative skills of school-age children with Down syndrome (DS) using an approach involving visual supports. Four females with DS, ages 10 through 15 years, participated in this multiple baseline across participants single-subject…
