Deficits in motor performance have been well documented in individuals with Down syndrome (DS). However, only a few studies have focused on manipulative skills and older adults in this population. Given the associations between manipulative skills and daily living activities, more work is needed to examine the aging effect on individuals with DS.…

Background: Children and adults with neurotypical development employ linguistic information to predict and anticipate information. Individuals with Down syndrome (DS) have weaknesses in language production and the domain of grammar but relative strengths in language comprehension and the domain of semantics. What is not clear is the extent to…

Background: Episodic memory deficits are a characteristic of cognitive dysfunction in people with Down syndrome (DS). However, less is known about the processes (i.e. encoding, retention or using learned information flexibly) that underlie these deficits. Method: We explored these abilities by administering a relational memory and inference task…

It has been reported that approximate number sense (ANS) task performance is impaired in individuals with Williams syndrome (WS) and Down syndrome (DS). Research with infants has suggested this impairment is caused by sticky fixation in WS and sustained attention deficits for those with DS. This study examined looking patterns of older children…

Purpose: Many observations and anecdotes have suggested that individuals with Down syndrome (DS) love music, specifically moving to music. The purpose of this study, with the assumption that the music makes people with DS dance showing more movement than general public's, is to observe the change in movement patterns of people with DS while they…

A number of studies suggest that imitation is a characteristic strength in children with Down Syndrome (DS). The present study aims to discover whether imitation performances are qualitatively phenotypical in DS. Eight preschoolers with DS were matched on chronological, mental, language and imitation age with 8 preschoolers with intellectual…

This longitudinal study examined pragmatic language in boys and girls with Down syndrome (DS) at up to three time points, using parent report, standardized and direct assessments. We also explored relationships among theory of mind, executive function, nonverbal mental age, receptive and expressive vocabulary, grammatical complexity, and pragmatic…
