Emotions and culture society. Therefore, it can be said that culture is a necessary framework for researchers to understand variations in emotions. In Darwin's opening chapter of "The Expression of the Emotions in Man and Animals", (1872/1998) Darwin considered the face to be the preeminent medium of emotional expression in humans, and capable of representing both major emotions and subtle variations within each one. Darwin's ideas about facial expressions and his reports of cultural differences became the foundation for ethological research strategies. Silvan Tomkins' (1962) "Affect Theory" 1963) built upon Darwin's research, arguing that facial expressions are biologically based, and universal manifestations of
Body language postural expressions of emotions such as anger/aggression, happiness, and fear. These similarities support the evolution argument that social animals (including humans) have a natural ability to relay emotional signals with one another, a notion shared by several academics (Chevalier-Skolnikoff, 1974; Linnankoski, Laakso, Aulanko, & Leinonen, 1994). Where Darwin notes similarity in expression among animals and humans, the Cultural Equivalence Model notes similarity in expression across cultures in humans, even though they may be completely different. One of the strongest pieces of evidence that supports this model was a study conducted by Ekman and Friesen (1971), where members of a preliterate
