A further rmANOVA, in which the percentiles P 1 , P 3 , and P 5 were compared, revealed a significant main effect of the factor time point ( F (1.61, 51.76) = 58.0, p < .001, η p 2 = .64), a marginally significant main effect of the factor percentile ( F (2, 64) = 2.84, p = .066, η p 2 = .08), and a significant interaction time point * percentile ( F (4, 128) = 13.19, p < .001, η p 2 = .29).
