Degrees of freedom for experiment 1: full model F(5,580), age effects/interactions F(2,580) and t(580); experiment 2: full model F(5,75), age effects/interactions F(2,75) and t(75). Boldface indicates p < 0.05 or Bayes factors > 3. See Table 1 for effect size conventions. Asterisks refer to interactions.
