Are there Racial Differences in Emotion Processing?

Abstract

Emotions are fundamental factors driving human behavior. Understanding how one's subjective experience of emotion translates to behavior is one of the central goals of cognitive neuroscience. Previous research has revealed differences in the expression and experience of emotions between racial groups. For instance, previous research has shown that African Americans are more emotionally expressive compared to individuals from other racial groups (e.g., Caucasians, Hispanics, and Asians). However, more research is needed to clarify these differences. The current study aimed to determine whether Caucasians and African-Americans differ in their experience and expression of emotion.  We hypothesized that African-Americans would demonstrate greater experience and expression of emotion compared to Caucasians. African-Americans (n=22) and Caucasians (n=51) were recruited from the community. The experiment consisted of showing participants four sets of films and having them answer questions about their current emotional state both before and after each set of films (to assess experience of emotion). Each set of film clips induced sadness, disgust, or happiness, and a neutral video was included as a control condition. Heart rate and skin conductance response (SCR) were recorded while participants watched the videos (to assess expression of emotion). Positive and negative affect composite scores were computed for each induction. No statistically significant differences were found between groups, suggesting that these racial groups do not differ in how they express emotions. It remains unknown whether these groups differ in how they experience emotions. We will continue collecting data in order to gain a better understanding of this phenomenon.
