Age Differences in Emotion Recognition of Briefly Presented Faces Lisa Emery, Kory Morgan, Kaitlyn Pechanek & Caitlin Williams EXPERIMENT 1: RESULTS INTRODUCTION 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. EXPERIMENT 1: METHOD Participants • 51 younger adults (Ages 18-22; M = 19.0, SD = 1.07; 29 Women) • 31 older adults (Ages 61-81; M = 69.3, SD = 5.80; 20 Women) Years Education* Operation Span* WAIS-III Vocabulary (Raw) ERQ-Suppression Self Monitoring* Young M SD 12.8 1.0 27.7 8.2 48.4 7.2 14.3 5.0 11.0 3.9 Old M SD 15.4 2.0 21.7 9.2 51.3 6.2 12.9 4.3 7.3 4.3 * Age Difference Significant at p < .05; None of these variables were associated with emotion recognition performance Procedure • 36 Trials Total, 6 each of Anger, Disgust, Fear, Sadness, Happiness, Surprise • Verbal response, recorded by Experimenter EXPERIMENT 2: METHOD 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. • There was a significant effect of Emotion Type, F(5,390) = 80.56, p < .001, Age Group, F(1,78) = 9.17, p = .003, and an Age Group x Emotion Type interaction, F(5,390) = 5.78, p < .001). • 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 < .001); Disgust, Happiness, and Surprise were all equally easy to recognize (all p’s > .20). EXPERIMENT 2: RESULTS Participant Responses for Incorrect Answers ANGER DISGUST FEAR SAD HAPPY SURPRISE YOUNG 0.33 0.20 0.18 0.07 0.06 0.17 OLD 0.23 0.27 0.14 0.07 0.07 0.23 • 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. EXPERIMENT 1: CONCLUSIONS • 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. • 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.
