In the Forced Choice Test, we observed a significant main effect of Block Length, F(1, 77) = 26.57, p < .001, ηp2 = 0.257, that did not differ with age, F(1, 77) = 1.59, p = .211, ηp2 = 0.020. Critically, the effect of age on recognition memory performance was not significant (F < 1), and this was true for both short (t < 1) and long, t(77) = 1.37, p = .17, block lengths. In contrast, Yes/No performance did not decline significantly as block length increased (F < 1), and this was true across both age groups, with no evidence of an interaction, F(1, 77) = 1.67, p = .20, ηp2 = 0.021. However, significant age differences in Yes/No performance persisted, F(1, 77) = 7.63, p < .01, ηp2 = 0.090.
