“…Our results of the dynamic–extrinsic category reached a similar conclusion as Morris et al . (2023), namely, that people with DS show no deficits in mentally manipulating spatial perspectives relative to external reference frames. Note that our results and Morris et al .…”

“…However, there was only one study on people with DS (Morris et al . 2023). In addition, various methodological choices, such as small and inadequate sample size, not matching two groups closely and ceiling effects, have made it difficult to draw definitive conclusions for various spatial domains.…”

BackgroundSpatial abilities are fundamental cognitive abilities, have direct applications in daily life, serve as a cognitive foundation for many other complex skills and are used in many specialty jobs. The current study aimed to systematically and comprehensively evaluate the spatial abilities of individuals with Down syndrome (DS) relative to mental ability‐matched typically developing (TD) children based on Newcombe and Shipley's double‐dimension theoretical framework for classifying spatial abilities.MethodsForty adolescents and young adults with DS and 40 TD children completed a nonverbal intelligence test (Raven's), two measures of static–extrinsic skills (water‐level task and cart task), two measures of static–intrinsic skills (figure ground and form completion), two measures of dynamic–extrinsic skills (three mountains task and dog task) and two measures of dynamic–intrinsic spatial skills (mental rotation task and block design task).ResultsParticipants with DS showed reduced performance on two dynamic–intrinsic tasks and one static–extrinsic task (i.e. cart task) relative to TD children. Performances were similar in two dynamic–extrinsic tasks and two static–intrinsic tasks. Analyses of composite accuracy for each spatial category further confirmed deficits in dynamic–intrinsic and static–extrinsic categories for people with DS relative to TD children.ConclusionsOur results showed an uneven profile of spatial abilities in people with DS relative to ability‐matched TD children with particular weaknesses in comprehending and manipulating dynamic–intrinsic and static–extrinsic spatial relations. Furthermore, our research has important clinical implications for more targeted interventions to improve spatial abilities in people with DS.
