We analyzed the arcsine transformed accuracy by a repeated-measures ANOVA and found a significant main effect of the condition ( F 1, 5 = 20.08, p = 0.007, η 2 p = 0.80), and an approached significant main effect of age ( F 1, 5 = 4.90, p = 0.08, η 2 p = 0.50), and interactions between condition and age ( F 1, 5 = 4.90, p = 0.08, η 2 p = 0.50).
