Lecture 3: Biological foundations
25/09/12
Aspects of biology that underlie social behaviour
- Hormones oxytocin: regulates stress and facilitates social bonding, cortisol
- Brainwaves EEG (small fluctuations in electrical activity generated by pops of neurons
in the brain); fMRI (measures changes in blood flow)
- DNA behaviour of genetics (twin studies); molecular genetics
- Physical appearance
- Reflexes and unconditioned responses
Biological foundations of social interaction
- Biological preparedness for social interaction babies come out rearing for social
interactions
- Neurological foundations: brain development/function to social behaviour
- Genetics
- Difference in temperament: how temperament interacts with your environment
Biological preparedness for social interaction
- From biological rhythms (e.g. sleep wake cycle) to social rhythms
Acquisition of biological regulatory skills interactional synchrony

Document Summary

Given what is known then what can be expected or what might be the case. Hormones oxytocin: regulates stress and facilitates social bonding, cortisol. Brainwaves eeg (small fluctuations in electrical activity generated by pops of neurons in the brain); fmri (measures changes in blood flow) Dna behaviour of genetics (twin studies); molecular genetics. Biological preparedness for social interaction babies come out rearing for social interactions. Neurological foundations: brain development/function to social behaviour. Difference in temperament: how temperament interacts with your environment. From biological rhythms (e. g. sleep wake cycle) to social rhythms. Acquisition of biological regulatory skills interactional synchrony. Development of biological rhythms that help babies deal with the time-based nature of social interaction. Faces, especially eyes will increasingly look more and more at the eyes and mouth and become very absorbed in those micro exchanges. Adults speak in shorter sentences and more slowly baby talk. Become attuned to native language by 9 months.
