ABSTRACT:
We examined the way in which infants with and without Down syndrome (DS) adapted their intrinsic dynamics, that is, their spontaneous leg movements, to perturbations. Weights totaling 25 percent, 50 percent, and 100 percent of their estimated calf mass were attached to one leg as they sat in an infant seat and moved freely. Particularly at higher weightings, infants in both groups demonstrated bilateral sensitivity and adaptability by increasing activity levels of the unweighted leg relative to the weighted leg. Individual differences in sensitivity thresholds were observed for both groups, but more infants with than without DS demonstrated minimal overt adaptation to the perturbation. We argue that the capacity to respond differentially to the dynamics of movement contexts is necessary for acquiring functional motor skill.
