Figure 4.

A, Averaged step symmetry adaptation (left column) and post-adaptation (right column) data for all subjects who showed significant aftereffects within each age group. Data were fit with linear, single-exponential, and double-exponential functions, and the one that resulted in the best fit (highest adjusted r²) is shown (all r² values are listed in Table 3). Linear functions resulted in the best fit for 3–5 yo adaptation and post-adaptation and 6–8 yo adaptation. Double-exponential functions resulted in the best fit for all remaining data. B, Comparison of step symmetry adaptation and post-adaptation rates across all age groups. Means ± SE are shown for adaptation (left) and post-adaptation (right). Significant main effects for age were found for step symmetry adaptation and post-adaptation. Post hoc analyses were performed on the significant main effect for age, and age groups that were found to be significantly different from adults are shown by colored asterisks.
