Children with Down syndrome had less efficient reach
strategies, and were more likely to show unsuccessful reaches
and extraneous position changes that did not provide
them with additional information to improve their reach.
Often, children with Down syndrome had to obtain a
direct visual map of the reach, as though they could not
have their hand move in a different route than their angle
of visual gaze. These findings may suggest that young children
with Down syndrome have praxis difficulties independent
of overall motor problems, and also that they may not
be using perceptual information in order to plan their
reaching strategy as effectively as children with other types
of developmental disabilities.
