We suggest that the kinds of faces we meet, the circumstances under which we interact with people and the way that we interact them, are profoundly influenced by the nature of facial expressions.
Facial expressions is one thing but reading people by their facial expressions and body language is another. We read people by their eye coordination and their body language. Body language is used to tell if someone is lying or not. Facial expressions is more popular than Facial expressions and body language.
A smile or a frown, for instance, can have different meanings. It can be:
• a speech-regulation signal
• a speech-related signal
• a means for signaling relationship
• an indicator for cognitive processes
• an indicator for an emotion
A given facial expression can have several meanings at the same time.
• These prototypes or major variants do only very rarely occur during spontaneous interactions.
• The meaning of a facial expression depends to a high degree on the situational context (verbal, other non-verbal channels, behaviour of the interaction partner, timing).
• There exists a high inter-individual variability. Many of the facial expressions shown by a person are person-specific.
Appraisal theorists following a componential approach share the assumption that:
a) emotions are elicited by a cognitive evaluation of antecedent situations and events and that
b) the patterning of the reactions in the different response domains (physiology, expression, action tendencies, feeling) is determined by the outcome of this evaluation process.
