χ2 = 26.36 (df = 34, p = 0.82), RMSEA < 0.001, CFI = 1.00, TLI = 1.73, SMRM = .08. Grouping is based on the study condition; figures separated by “/” if they differed between the groups. U: updated from Study 1. 3 outliers deleted; parameters freed across groups: FFAUS (2nd half) regressed on navigation method and SFAUS regressed on start time. ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.
