The Development of Visually Guided Stepping [dataset] Open Access

Adults use vision during stepping and walking to fine-tune foot placement. However, the developmental profile of visually guided stepping is unclear. We asked i) whether children use online vision to fine-tune precise steps and ii) whether precision stepping develops as part of broader visuomotor development, alongside other fundamental motor skills like reaching. With 6 (N=11), 7 (N=11), 8 (N=11) year olds and adults (N=15), we manipulated visual input during steps and reaches. We measured step and reach error and postural stability using motion capture. We expected i) both steps and reaches would be visually guided ii) with similar developmental profiles iii) foot placement biases that promote stability and iv) correlations between postural stability and step error. Children used vision to fine-tune both steps and reaches. At all ages, foot placement was biased (albeit not in the predicted directions). Contrary to our predictions, step error was not correlated with postural stability. By 8 years, children’s step and reach error were adult-like. Despite similar visual control mechanisms, stepping and reaching had different developmental profiles: step error reduced with age whilst reach error was lower and stable with age. We argue that the development of both visually guided and non-visually guided action is limb-specific.
