χ2 = 2.87 (df = 13, p = 1.00), RMSEA < 0.001, CFI = 1.00, TLI = 1.25, SMRM = 0.02. Grouping is based on walking direction: C, clockwise; R, reverse; figures separated by “/” if they differ between the groups. Parameters freed across groups: RT regressed on stress, covariance between commission errors and SDRT. ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.
