ABSTRACT

ABSTRACT Judgments of emotional stimuli’s valence and arousal can differ based on the perceiver’s age. With most of the existing literature on age-related changes in such ratings based on perceptions of visually-presented pictures or words, less is known about how youth and adults perceive and rate the affective information contained in auditory emotional stimuli. The current study examined age-related differences in adolescent (n = 31; 45% female; aged 12–17, M = 14.35, SD = 1.68) and adult listeners’ (n = 30; 53% female; aged 21–30, M = 26.20 years, SD = 2.98) ratings of the valence and arousal of spoken words conveying happiness, anger, and a neutral expression. We also fitted closed curves to the average ratings for each emotional expression to determine their relative position on the valence-arousal plane of an affective circumplex. Compared to adults, adolescents’ ratings of emotional prosody were generally higher in valence, but more constricted in range for both valence and arousal. This pattern of ratings is suggestive of lesser differentiation amongst emotional categories’ holistic properties, which may have implications for the successful recognition and appropriate response to vocal emotional cues in adolescents’ social environments.
