There are more than 7,000 languages spoken in the world today, but sometimes facial expressions communicate much more than words, regardless of your mother tongue. Whether facial expressions and the emotions that underlie them are preserved across cultures has been a subject of great debate for years.
Studies that have attempted to document the universality of facial expressions have typically relied on experiments in which participants had to label photos of posed expressions. If there’s a consensus among participants from different cultural backgrounds about what behaviors reflect “joy”, “anger” or some other affective state, then this would be evidence of universal patterns of behavior.
