Social situations induce facial expressions in toddlers and children in early childhood, although there is not enough evidence to indicate that they understand these expressions as emotions. For example, a young child could express sadness when his or her mother is in the room in order to elicit a nurturing reaction from her. [ 2 ]
The development of FACS tools for different species allows the objective and anatomical study of facial expressions in communicative and emotional contexts. Furthermore, a cross-species analysis of facial expressions can help to answer interesting questions, such as which emotions are uniquely human. [21]
For example, when Western individuals are asked to identify an emotional expression on a specific face, in an experimental task, they focus on the target's facial expression. Japanese individuals use the information of the surrounding faces to determine the emotional state of the target face. [ 29 ]

According to Ekman (1992), each of these emotions have universally corresponding facial expressions as well.
