Effect sizes for the total age effect (linear and quadratic) and for the linear/quadratic effects separately are expressed as the proportion of explained variance (

*R*^{2}), as a percentage, and as standardized regression coefficients (β), respectively. Degrees of freedom in experiment 1: age effect*F*_{(2,583)}and*t*_{(583)}; experiment 2: Age*F*_{(2,78)}and*t*_{(78)}. Boldface indicates*p*< 0.05.
