 The main source of evidence for basic affect programs arguably comes from cross-cultural studies on facial expressions that use a recognition technique first described by Darwin (1872). It consists of showing pictures of emotional expressions and asking observers what emotions they express from a list of six to ten emotion terms in the observer’s language. As reported by Ekman (1999b), experiments of this sort have so far been performed with observers from dozens of countries, revealing significant agreement on which emotion is portrayed (the recognition rates are strongest for happiness, sadness and disgust). This being said, membership to a given culture increases recognition of expressions from that culture, which has led some to argue that emotional expressions are a universal language with different dialects (Elfenbein et al. 2007).
