Figure 7. Positional variability of the COP in the AP axis as a function of stance width during performance of the Inspection and Search tasks.

A. Before warm-up. B. After warm-up. *, post-hoc effect showing that before warm-up sway was reduced during performance of the Search task, relative to sway during performance of the Inspection task, when stance width was 17 cm, p<.05. The error bars represent standard error of the mean.
