Aspects of biology that underlie social behavior Hormones Oxytocin usually called the love hormone Brainwaves Many different ways of measuring brainwaves EEG-measures small fluctuations of electricity in the brain non invasively Functional MRI –measures blood level changes DNA Study behaviorally Molecular genetics Physical Differences in physical maturation can influence social interactions Some of these biological mechanisms explain why people experience things that affect how they act for the rest of their lives How robotic our we? Can we transcend who we are to become better? Biological foundations of social interaction Lays does the idea that babies are equipped with how to interact with people Basic brain development and functions and specific dev’t which affect behavior How are babies prepared? Biological rhythms (sleep-wake cycle), many biological systems operate like this, cortisol levels are like this too (cyclic) These biological rhythms can enhance our development, enhancing social rhythms There is a claim that the acquisition of biological skills affect how/when we Babies need to develop biological rhythms (fixing sleep patterns, etc) Idea that those who develop normally will develop a healthy development of social skills Premature babies don’t develop circadian rhythms as well as normal babies Idea that oxytocin wipes away previous memories and focuses on forming a new relationship with the other person Visual preparation for social interaction Babies attracted to faces and look more and more at the eyes Auditory preparedness Well developed before birth In the womb babies can take in experiences and hear stories being read to them Learning and remembering can occur before birth, but after birth is wiped away. Just because we don’t recall things in the womb, doesn’t emean we don’t have the capacity Smell, taste, touch Infants can tell the difference between odors Get taste of food that the mother eats during pregnancy Prefer mothers smell (other species spell makes the mother like the baby and if they don’t have that regular sense of babies smell wont take care of the infant) Touching has physiological effects that lead to developmental effects Deprivation of touch has negative effects on normal development If infants were given massages (15 mins a day) got to leave the hospital a week early and had better physiological senses that other infants Beyond faces and voices Infants very good social agents These interactions help the infant self regulate, if too exciting/stimulating they calm themselves by looking away Disruption can cause difficulty Cocaine exposed infants don’t know how to self regulate well and turn away if something is too stimulating Dyadic regulation Other self-regulation The notion that we need someone to change the st
