Regressions between measures of variability (MeanSD) and short-term local divergence time constants ( Ï„ S ; left column), long-term local divergence time constants ( Ï„ L ; middle column), and magnitudes of maximum Floquet multipliers (MaxFM; right column) for movements in the AP (top row), ML (middle row), and VT (bottom row) directions. Each subplot show the average value for each subject for both Stroop ('O') and Control ('X') walking trials. Linear regressions were performed for AP and VT movements, while quadratic regressions were performed for ML movements. Adjusted r2 values and p-values for each regression are shown in each sub-plot. Since each regression contained two data points from each subject, these p-values do not indicate "statistical significance" in the strict sense, but instead indicate only the general quantitative strengths of these relationships.
