To what extent do most cultures recognize the same specific emotions?

Some cultures only have words for red, white, and black, while other cultures have words for red, orange, yellow, etc.—does the same hold for emotions?

Put another way: in primary schools, there are posters with cartoon faces caricaturing important emotions, but would an analogous poster on the other side of the world be likely to have the same categorization?

There are a certain set of base emotions that are pretty much universal in healthy humans.

Brain scans and neurological studies have indicated that the amygdala plays an important part in the expression of emotion, fear in particular.  

There are also physiological reactions associated to emotions.  The Cannon-Bard theory of emotion, also known as the Thalamic theory of emotion, is a physiological explanation of emotion developed by Walter Cannon and Philip Bard. Cannon-Bard theory states that we feel emotions and experience physiological reactions such as sweating, trembling, and muscle tension simultaneously.

According to the Cannon-Bard theory of emotion, we react to a stimulus and experience the associated emotion at the same time. The physical reactions are not dependent upon the emotional reaction, or vice versa.

Psychologically, the expression of emotion and our interpretation of it seems to be universal in healthy individuals.   Interpretation of emotional sign is tied to cognition and emotional intelligence, and these expressions play a major part in our overall body language.

Research suggests that many expressions are universal, such as a smile to indicate happiness or a frown to indicate sadness. Sociocultural norms also play a role in how we express and interpret emotions.

In 1972, psychologist Paul Eckman suggested that there are six basic emotions that are universal throughout human cultures: fear, disgust, anger, surprise, happiness, and sadness.

This was later added to Robert Plutchik in the 1980s when he introduced another emotion classification system known as the "wheel of emotions." This model demonstrated how different emotions can be combined.

In 1999, Eckman expanded his list to include a number of other basic emotions, including embarrassment, excitement, contempt, shame, pride, satisfaction, and amusement.

There has been considerable study into the nature and expression of emotion.
