χ2 = 9.70 (df = 13, p = 0.72), RMSEA < 0.001, CFI = 1.00, TLI = 1.27, SMRM = 0.04. Grouping is based on walking direction: C, clockwise; R, reverse; figures separated by “/” if they differed between the groups. 4 outliers deleted; parameters freed across groups: FFAUS (both halves) regressed on start time. ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.
