facial expressions and gestures


Generally speaking - almost every gesture carries some emotional “baggage” with it - it all depends on the context which it appears in. But to keep it simple, in these articles on affect displays I will focus on hand gestures that have little purpose besides revealing a certain emotion or a “tone” to whatever is being said, be it intentionally or accidentally.

facial expressions

The eyes are often viewed as important features of facial expressions. Aspects such as blinking rate can be used to indicate whether or not a person is nervous or whether or not he or she is lying. Also, eye contact is considered an important aspect of interpersonal communication. However, there are cultural differences regarding the social propriety of maintaining eye contact or not.
