Document Summary
Phylogeny roots of nonverbal behaviour in human evolutionary history (innate, instinctive, genetic) Ontogeny roots of nonverbal behaviour in our lifetime (acquired, learned, culturally taught. 3 primary sources of nonverbal behaviour: inherited neurological programs, experience common to all members of the species, experience that varies with culture. Studies about nature vs nurture: human infants. The expressions of infants may be undifferentiated responses to stimuli. They express joy, surprise and interest but there is no way to be sure that they are actually feeling those emotions. Negative emotions as expressed by adults such as fear, anger, disgust and sadness. Pain in infants is easily communicated and similar to pain as displayed by adults: lowered brow, eyes squeezed tightly shut. However infants quickly begin to imitate adults (. 7 to 71 hours old) This indicates that infants are born with the ability to make a connection between what they see and the act they then perform.
