marginally significantp = .055
Concerning negative affect at 3 months of age, the main effect of phase was marginally significant, F (1, 42) = 3.89, p = .055, η 2 = .09, pointing towards an increase in negative affect from baseline to the interruption phase across samples. 2 The ANOVA yielded no significant main effect of cultural milieu, F (1,42) = 0.07, p = .798, η 2 = .00, nor a significant interaction of cultural milieu × phase, F (1,42) = 0.00, p = .990, η 2 = .00.
