Nature, Nurture, Diversity, Development (Ch 4/5) Flashcards
heritability
the proportion of varation among individuals that we can attribute to gens.the hertability of a trait may vary, degending on hte range of populations and environments sdudied.
If the heritability of intelligence is 50 percent, that does not mean that your intelligence is 50 percent genetic. rather it means that genetic influence explains 50 percent of the observed variation among people
collectivism
giving priority to goals of ones group (often one’s extended faimly or work group) and defining one’s identity accordingly
Fetal Alcohol Syndrome (FAS)
physical and cognitive abnormalities in children caused by a pregnant woman’s heavy drinking. in severe cases, symptoms includ noticeable facial misprotortions
habituation
decreasing responsiveness with repeated stimulation. as infants gain familiarity with repeated exposure to a bisual stimulus, their interest wanes and they look away sooner ( this seeming boredom with familiar stimuli gives us a way to ask infants what they see and remember)
Assimilation (piaget)
interpeting our new experience in terms of our existing schemas. . having a simple schema for cow, a toddler may call all four legged animals cows.
accomodation
adapting our current understanginds (schemas) to incorporate new information
Piaget
Sometimes Piaget Can conFuse Sensorimotor Preoperational Concrete operational formal operational
sensorimotor
- piaget
- birth to 2 years
- the stage during which infants know hte world mostly in terms of their sensory imperssions and motor activies
- lack object permanence until about 8 months
Researchers believe Piaget underestimated power of baby logic
- shown numerically impossible outcomes of puppets on screen, infants stare longer
- stare longer at impossible objects and situations
preoperational
2 - 6/7 years
- child learns to use language but does not yet comprehend the mental operations of concrete logic
- lacks conservation
- egocentric =>
- theory of mind - develops around age 4
Judy DeLoache (1987) showed that 3 year olds could understand some symbolic thinking, understanding that models were a symbol for a room ( in stuffed animal hiding in model couch experiment) p 183
conservation
the principle that quantity remains the same despite changes in shape
-egocentric
in Piaget’s hteory, the preoperational child’s difficulty taking another’s point of view
asked to “show mommy yourpicture” 2 year old Dabriella holds the picture up facing her own eyes. three year old Gray makes himself “invisible” by putting his hands over his eyes, assuming that if he can’t see his grandparents they can’t see him”
theory of mind
people’s ideas about their own and others’ mental states -about their feelings, perceptions, and thoughts, and the behaviors these might predict
starts developing around age 4, when children worldwide come to realize that others may hold false beliefs (e.g. changing what is inside of a box, and realizing that the other person will still think that the old object is in the box
children with autism
have difficulty understanding that Sally’s state of mind differs from their own- that sally not knowing the ball has been moved will return to e red cupboard.
they also have difficulty refflecting on their own mental statesi they are for example less likely to use the personal pronouns Iand me.
deaf children and theory of mind
deaf children who have hearing partens and minimal communication opportunities have similar difficulty inferring others’ states of mind
We are able to appreciate others’ perceptions and feelings before we can appreciate
others’ beliefs (with regard to the age in our development)
