Young adults found Happiness and Surprise easier to recognize than the four negative emotions, and Happiness easier to recognize than surprise (all p’s <.001). Older adults found Disgust, Happiness, and Surprise easier to recognize than Fear, Sadness, and Anger (all p’s.20). Overall, the performance in Experiment 2 was similar to the young adult’s performance in Experiment 1. The Effect of Emotion Type was significant, F(5,225) = 43.15, p <.001 and showed the same pattern as in Experiment 1. Neither the Condition Effect, F(1,45) = 0.38, p =.56, nor the Condition x Emotion Type interaction, F(5,225) = 0.11, p =.990, was significant. In Experiment 2, we tested an exploratory hypothesis that age-impairments in vision may partially account for this finding. Fifty young adults were randomly assigned to perform the same test with either typical pictures, or pictures “blurred” to mimic age-related visual declines. Previous research has found that, when identifying emotional expressions from static faces, older adults show impaired recognition for some emotions (e.g., sadness, fear, anger), but spared or even improved recognition on others (e.g., happiness, surprise, disgust). There are several limitations to previous research, however, including possible ceiling effects in young adults and a lack of ecological validity. In Experiment 1 we used a modified emotion recognition test in which posed emotion expressions were briefly presented in-between neutral expressions, in order to mimic fleeting emotional expressions and increase difficulty. In a second experiment, we tested the potential role of age-related perceptual decline in emotion recognition by mimicking these declines in younger adults. * Age Difference Significant at p <.05; None of these variables were associated with emotion recognition performance EXPERIMENT 2: METHOD EXPERIMENT 2: RESULTS Overall, the age differences in speeded emotion recognition mimic those found with static faces. We did not correct for possible response bias, which could, in part, explain older adults’ performance on this emotion. Participant Responses for Incorrect Answers When participants responded incorrectly, younger adults were more likely to respond “ANGER” than older adults were, and older adults were slightly more likely to respond “DISGUST” or “SURPRISE” than younger adults were. 36 Trials Total, 6 each of Anger, Disgust, Fear, Sadness, Happiness, Surprise Verbal response, recorded by Experimenter
