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.
本研究考察了种族群体成员身份与情感的声音表达之间的关系。使用非言语准确性诊断评估2接受性副语言子测试，对18名年轻的欧美裔和非裔美国女性进行了识别准确性和反应时间的测试。参与者聆听欧美裔儿童和成人说出的中性句子，并识别出其中表达的快乐、悲伤、愤怒或恐惧的情绪。分析发现种族对反应时间有显著影响。在识别欧美裔人所表达的情感声音时，欧美裔参与者的平均反应时间比非裔美国女性更快。然而，两组在平均准确识别率上没有发现显著差异。成人和儿童说出的刺激语在识别反应时间上存在显著差异，但在准确性上没有差异，这一发现出乎意料。两个种族群体对儿童情感声音表达的平均反应时间都更快。
