本研究探讨了种族群体成员和情感的声音表达的关系。识别准确性和反应时间进行了检查，使用非语言准确性诊断评估2接受副语言子测试与18名年轻的欧洲裔美国人和非洲裔美国妇女。参与者听欧美儿童和成年人说一个中性的句子，并确定情绪为快乐，悲伤，愤怒或恐惧。分析发现种族对反应时间有显著影响。欧美参与者比非洲裔美国妇女更快的平均RT识别的声音表达的情绪描绘的欧美人。然而，两组之间的平均准确识别没有显着差异。发现一个显着的差异识别RT，但不是在准确性之间的刺激由成人和儿童是出乎意料的。这两个种族群体有更快的平均反应时，由儿童的情感表达的声音。
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.
