Description
March 26, 2013. Lecture 9 - Human Development and Personality  Cognitive dissonance: unpleasant arousal, inner tension, brain makes up for tension and discrepancy o E.g. brain convincing you to believe lies to lessen tension, or exaggerate how great a choice you make is and how bad the alternative option was o Once thought to be a cross cultural phenomenon, but with collectivistic cultures it works differently o Cognitive dissonance is about protecting the consistency of the self, something important to the psychology of the individual within Western/individualistic cultures o With collectivist cultures, the self is kind of relative to the group surrounding the individual What IS Human Nature?  Biology vs. culture, nature vs. nurture  Given that they are always intertwined, how can we know whether there is such a thing as “innate” human nature, and what that would look like?  Biocultural beings, right from the beginning of our lives we are influenced by both biological inheritance and environmental factors/outside influences  Babies o Prenatal and infant development progress in highly predictable ways and are, largely, the result of genetic “programming” o Of course, even prenatal and infant development are affected by environmental factors  E.g., teratogens (e.g., alcohol, viruses, drugs, etc.) can cause abnormal development in the womb; many chemicals pervasive in the environment are now found in fetuses  Body burden studies found that babies in the womb have absorbed half of tested industrial chemicals  E.g., stress and mother’s emotional state  birth weight, cognitive and physical development  Surrounding family, world issues, economic situation, etc. can all affect baby’s development  E.g., cultural practices (e.g., sleeping on backs vs. fronts )  crawling  Used to always put babies to sleep on their stomachs, was found to increase the risk of SIDS (sudden infant death syndrome)  We now put them to sleep on their backs, which apparently slows down their motor development o Development of emotional security a key factor in development of infants  E.g., skin to skin contact, attention to needs and crying  In North American culture these things are often replaced by strollers, motorized swings that sing songs, play pens, etc. all to entertain and distract the baby o Brain development (myelination, formation of connection between neurons) is also dependent on proper environmental stimulation, nutrition, etc. o So, even at the earliest ages, human development is an interaction between nature and nurture  The Role of the Environment: some examples of children growing up in extreme circumstances have profoundly deepened our understanding of the role of the environment in human development o E.g., studies of children growing up in Romanian (and other) orphanages, and other situations of neglect o Severe cognitive and psychological damage done due to this neglect, some of which can be repaired/made up for by love and support later in life, but some is irreparable o Note differences between “sensitive period” and “critical period”  Feral Children: Victor – The “Wild Boy of Aveyron”; captured 1797; escaped, re-emerged 1800 o Aimed to “civilize” Victor  Didn’t dress in proper clothes, have manners, communicate properly, eat with cutlery, etc. o He made a lot of progress in his training, but also plateaued really early on and would never be able to expand past this point  Same with Saturday Mifune – raised by monkeys to age 5; violent, naked, ate raw meat, veggies and of course, bananas o The way we behave is not entirely due to genetic programming, we are largely shaped into what we become o 1970: Genie; escaped from abusive father with her mother, was 4 ½ feet tall, 59 pounds, seemed 6-8 years old, turns out she’s 13  Also had weird qualities to her, disinterested in environment, unresponsive, walked oddly, motor functioning was strange, didn’t speak much, mentally delayed, could not fully extend her limbs  No biological reasons for this poor development  Turns out she spent more than 10 years locked in a tiny, dark room, tied to a chair and caged at night. No human contact except for beatings if she made noise, no stimulation…. Nothing.  Didn’t understand much language, could only form the briefest of sentences such as “stop it” and “no more”  For four years was cared for emotionally, psychologically and physically. She made progress, but plateaued very quickly. o Extreme cases like these show us that being human is, like pretty much everything we’ve learned about, more like a skill than an innate ability; it’s something we learn through PRACTICE, being bathed in language, cultural practices and affection  The Importance of Social Contact: a key theme in developmental psychology is that humans are profoundly social beings o Who we are depends to an extraordinary degree on the human contact we have throughout our lives, from learning language to developing a sense of emotional security, to adopting the beliefs, habits, and general “way of being” of our families o The central part of this process is the formation of attachment  Attachment is the bond that develops between the caregiver and child; the emotional connection  Babies are designed to form attachments, and elicit attachment-forming behaviours from adults  Adults have certain innate responses to babies actions; fairly automatic o E.g., holding out arms, smiling, crying, settling down when held o Adults respond almost automatically; e.g., picking up, exaggerated expressions, higher pitched voices o First “social smile” occurs 4 – 6 weeks of age…. (and it’s a good thing it does…)  Infants are social
