“…Such cultural specificities -called 'accents' or 'dialects' (Elfenbein, 2013;Elfenbein, Beaupre, Levesque, & Hess, 2007;Marsh, Elfenbein, & Ambady, 2003;Silvan S. Tomkins & Robert McCarter, 1964), or 'modifiers' in animal communication (Jenssen, 1977(Jenssen, , 1979 -are widely discussed in the literature (Ekman, 1972;Elfenbein, 2013;Matsumoto, Yoo, & Fontaine, 2008;Mesquita & Frijda, 1992). For example, Japanese nationals and Japanese Americans are reliably distinguished on the basis of expressive but not neutral facial expressions (Marsh et al, 2003), suggesting the embedding of cultural accents (see also Marsh, Elfenbein, & Ambady, 2007). Yet, segregating culturally common AU patterns (i.e., basis AUs) from those that are culture specific (i.e., modifier AUs) has remained challenging as detailed above (Labarre, 1947).…”
