Nonverbal Communication 1/18/17
Chapter 2 The roots of nonverbal communication
Phylogeny vs Ontogeny
o Phylogeny: the development of NV behavior across evolutionary time
o Ontogeny: the rots of NV behavior in our current lifetime
Ex: that are created from both
Cross your arms (now do it the other way)
Cross your legs (many different types)
Interlace your fingers (do it the other way)
o Nature vs nurture as explanations of our acquiring NV behaviors
o Innate vs learned
Innate vs learned Eibl-Eibesfeldt’s studies
o Evidence from sensory deprivation
Expressions are not significantly different between blind and deaf children and
typical developing children

Mostly nature with a nurture component
o Evidence from infants
Nature and nurture mostly nurture
Infants mimic faces
o Evidence from twin studies (pg. 42)
Nature
Identical twins who grew up apart still exhibited the same body language
Fraternal twins only sometimes showed similarities
Not enough studies done on identical twins and nonverbal language
o Evidence from non-human primates
Facial expressions are nature
Meaning of the expressions are nurture
o Evidence from multicultural studies
Facial expression is innate
Meaning is supplied by nurture
Ex: eyebrow flashes
Fear and surprise get confused
Non-literate cultures have a more difficult time successfully interpreting facial
expressions
