Variation among European Americans in emotional facial expression

The authors examined whether European Americans (EA) several generations removed from their ancestors varied as a function of their countries of origin by comparing the emotional facial expressions of EA originally from Scandinavian countries (EA-S), who value emotional control, and those from Ireland (EA-I), who value emotional expression. EA-S were less expressive than EA-I while reliving various emotions, especially happiness and love, suggesting that in this domain, EAs continue to be influenced by their cultural heritages.
