September 24, 2012. in private culture has less of an affect than in public. Oxytocin help regulate stress, facilitates social bonding, love hormone . Eeg measures small fluctuations in electrical activity, on surface of scalp, generated by whole populations of neurons in the brain fmri measuring changes in blood flow. Studying it behaviourly behavioural genetics, twin studies. Differences in physical maturation, influence on social development reflexes and unconditioned responses. How much control do we actually have over these biological mechanisms? influence behaviour for rest of life that they have very little control over. Preparedness babies come into this world just rearing to interact w/ people. Biological rhythms sleep-wake cycle (wake up, go to sleep) Cortisol: really elevated when wake up, by evening it"s very low, at night it stays really low until an hour before you wake up the levels sky rockets. Predicts ability to interact w/ people (interactional synchrony)
