Finding: It is hypothesized that the external focus of attention condition will outperform the internal focus of attention condition when responding to perturbations. The external focus of attention condition will yield faster response time and show improved compensatory responses compared to the internal focus of attention group by producing a greater lateral displacement of the artificial limb relative to the line of progression. In addition, the external condition will demonstrate a greater step length and step height than the internal focus of attention condition when provided with a perturbation.
