Notes
1 As in Study 1, a main effect of object level was qualified by an interaction with age, F(1, 76) = 10.36, p = .002, η2 = .12. Participants responded faster when the relevant object was in the front than in the rear. This difference was larger for older adults.
2 Prior analyses included order of blocks (effect-coded: negative/positive = −1, positive/negative = 1) and its interaction terms. Order had no significant influence.
