Neuropsychology of social cognition: culture, display rules, and emotional expressivity.

Introduction: We investigated the roles of group ethnicity and display rules of emotions in the neuropsychology of social cognition in Asian American and White participants recruited from a majority-minority college campus.

Method: 128 participants (mean age = 24.9 years) completed: 1) Advanced Clinical Solutions-Social Perception (ACS-SP), which includes separate measures of affect naming of facial expressions and emotional prosody interpretation of audio statements; 2) Display Rule Assessment Inventory (DRAI), a self-report measure of emotional expressivity across four settings (family, close friends, colleagues, and strangers) and in two distinct domains (should/actual) that asks participants what they believe people should do (social value) and what they would actually do (behavioral self-report).

Results: ACS-SP revealed evidence of cultural bias, as reflected by group ethnicity differences, for recognition of emotional prosody but not emotional facial expressions for Asian American versus White participants. The DRAI showed significant cultural differences only for family relationships with White participants endorsing stronger belief in the social value of expressing negative emotions of sadness, aversion, and fear. These AC-SP and DRAI group differences remained significant when covarying for spoken English language, as measured by an oral word reading test. Hierarchical regression results indicated that group ethnicity and family display rules each made specific and significant contributions to neuropsychological performance but did so in very different and distinct ways. Group ethnicity exerted its greatest effect on prosody interpretation whereas family display rules had its most pronounced influence on affect naming.

Conclusions: The current results may help inform and advance culturally responsive neuropsychological models of social cognition.
