Introducing a Face Sort Paradigm to Evaluate Age Differences in Emotion Perception.

OBJECTIVES: Previous research has uncovered age-related differences in emotion perception. To date, studies have relied heavily on forced-choice methods that stipulate possible responses. These constrained methods limit discovery of variation in emotion perception, which may be due to subtle differences in underlying concepts for emotion. METHOD: We employed a face sort paradigm in which young (N = 42) and older adult (N = 43) participants were given 120 photographs portraying six target emotions (anger, disgust, fear, happiness, sadness, and neutral) and were instructed to create and label piles, such that individuals in each pile were feeling the same way. RESULTS: There were no age differences in number of piles created, nor in how well labels mapped onto the target emotion categories. However, older adults demonstrated lower consistency in sorting, such that fewer photographs in a given pile belonged to the same target emotion category. At the same time, older adults labeled piles using emotion words that were acquired later in development, and thus are considered more semantically complex. DISCUSSION: These findings partially support the hypothesis that older adults' concepts for emotions and emotional expressions are more complex than those of young adults, demonstrate the utility of incorporating less constrained experimental methods into the investigation of age-related differences in emotion perception, and are consistent with existing evidence of increased cognitive and emotional complexity in adulthood.

Perceptions of rapport across the life span: Gaze patterns and judgment accuracy.

Although age-related deficits in emotion perception have been established using photographs of individuals, the extension of these findings to dynamic displays and dyads is just beginning. Similarly, most eye-tracking research in the person perception literature, including those that study age differences, have focused on individual attributes gleaned from static images; to our knowledge, no previous research has considered cue use in dyadic judgments with eye-tracking. The current study employed a Brunswikian lens model analysis in conjunction with eye-tracking measurements to study age differences in the judgment of rapport, a social construct comprised of mutual attentiveness, positive feelings, and coordination between interacting partners. Judgment accuracy and cue utilization of younger (n = 47) and older (n = 46) adults were operationalized as correlations between a perceiver's judgments and criterion values within a set of 34 brief interaction videos in which 2 opposite sex college students discussed a controversial topic. No age differences emerged in the accuracy of judgments; however, pathways to accuracy differed by age: Younger adults' judgments relied on some behavioral cues more than older adults. In addition, eye-tracking analyses revealed that older adults spent more time looking at the bodies of the targets in the videos, whereas younger adults spent more time looking at the targets' heads. The contributions from both the lens model and eye-tracking findings provide distinct but complementary insights to our understanding of age-related continuities and shifts in social perceptual processing.
