Emotion discrimination improves with age. D-prime, an index of emotion recognition, increased linearly with age suggesting that emotion discrimination improved with increasing age. Regardless of age, females had better emotion discrimination than males, happy and fear faces were the most accurately discriminated, and d-prime was lower during conditions when emotional faces were the “nogo” stimuli. H, happy; F, fear; A, angry; S, sad; dotted bars are D-prime mean values averaged over emotions for each age group.
