Abstract

Previous research has indicated that individuals with Down syndrome (DS) have difficulties processing auditory movement information relative to their peers with undifferentiated developmental disabilities. The present study was conducted to assess whether a model of atypical cerebral specialization could explain these findings. Thirteen adults with Down syndrome (8 men, 5 women), 14 adults with undifferentiated developmental disabilities (7 men, 7 women), and 14 adults without disabilities (8 men, 6 women) performed rapid aiming movements to targets under three conditions: a visual cue at the target location, a visual cue remote from the target location, or a verbal cue. Results revealed that, while the reaction times did not differ between the two groups with disabilities across conditions, the participants with DS, unlike their peers, had significantly longer movement times in the verbal than in two visual conditions. These results are consistent with the model of biological dissociation.
