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