Recognition accuracy and reaction time of vocal expressions of emotion by African-American and Euro-American college women

Percept Mot Skills. 2004 Oct;99(2):662-8. doi: 10.2466/pms.99.2.662-668.

Abstract

This study examined the relationship of racial group membership and vocal expressions of emotion. Recognition accuracy and reaction time were examined using the Diagnostic Assessment of Nonverbal Accuracy 2 Receptive Paralanguage subtests with 18 young Euro-American and African-American women. Participants listened to Euro-American children and adults speaking a neutral sentence, and identified the emotion as happy, sad, angry, or fearful. Analysis identified a significant effect for race on reaction time. Euro-American participants had faster mean RT than the African-American women for the recognition of vocal expression of emotion portrayed by Euro-Americans. However, no significant differences were found in mean accurate identification between the two groups. The finding of a significant difference in recognition RT but not in accuracy between the stimuli spoken by an adult and a child was unexpected. Both racial groups had faster mean RT in response to vocal expression of emotion by children.
