Darwin, six basic human emotions (happiness, surprise, fear, disgust, anger, and sadness) are expressed using the same facial movements across all cultures, supporting universal recognition. According to Seyda Özçalıskan, a Researcher at Georgia State University, language can influence non-verbal representations of events; however, when no language is involved, these language-specific differences in gestures disappear, letting researchers suppose there may be some universals in gestures when verbal communication is absent.
