The same with age: Evidence for age-related similarities in interpersonal accuracy

Interpersonal accuracy refers to the ability to make accurate perceptions about others' social and emotional qualities. Despite this broad definition, the measurement of interpersonal accuracy remains narrow, as most studies focus on the accurate perception of others' emotional states. Moreover, previous research has relied primarily upon traditional tasks consisting of posed, prototypic expressions and behaviors as stimuli. These methodological limitations may constrain our understanding of how different interpersonal perception skills change in adulthood. The present study investigated the extent to which various interpersonal perception skills are worse, better, or remain the same with age using both traditional and nontraditional interpersonal accuracy tasks. One hundred fifty-one adults from 3 age groups (young, middle age, and older) completed a battery of interpersonal accuracy tasks that assessed eight different emotion perception skills and six different social perception skills. Analyses revealed age-related differences in accuracy for five interpersonal perception skills; differences were typically observed between younger and older adults on emotion perception accuracy and between younger and middle-age adults on social perception accuracy. In contrast, almost all remaining interpersonal perception skills-both emotional and social-revealed greater evidence for age-related similarities than differences in Bayesian analyses. Additional exploratory analyses indicated that the observed age differences in interpersonal accuracy may be attributable to individual differences in cognitive ability rather than age. Results provide a nuanced picture of how interpersonal perception skills change in adulthood and provide new methodological tools for a more complete and comprehensive assessment of interpersonal accuracy.
