Final exam Flashcards
Piagets Theory of Cognitive Development
Children construct knowledge by manipulating and exploring their world. We create knowledge through adaptation - we create it all ourselves and it has two different prongs which allow it to operate. also assimilation and accommodation.
3 stages: Sensorimotor, preoperational, concrete operations
assimilation
what we already know with the numbers using context clues
accommodation
world is in disequilibrium and you must change yourself, what you know doesn’t fit into new context
Sensorimotor
Preoperational (age 2-7)
- gains in mental representation
- kids can think in symbols, words start having meaning
- object permanence, can ask for things they cant see directly
- idea of fairness or equality doesnt exist yet for you
- conservation
- decentration: multiple aspects of the situation into account for all the parts for it (
- centration:
- irreversibility:
Concrete Operations
- Seriation: ability to put things in order (6-7 years)
- transitive Inference: ability to seriate mentally (7 years)
- Spacial Reasoning: how do we describe where we live
- preschool- landmarks
- 7/8
brazil kids : culture can force kids to learn things faster or different than in school
Vygotsky’s Sociocultural Theory
Transmission to the next generation of a culture’s values, beliefs
- novices can learn from experts despite the age,
kids can tell their beliefs in god
Ecological Systems Theory
interview or Structred and naturalistic observation. how child is impacted by circles surrounding them in encironement from close to farther connections with them in day to day
Mitosis & Meosis
Mitosis: the process by which DNA duplicates
- Meiosis: sex cells have formed, leading to genetic variability
Down Syndrome
Incomplete injection of the egg cell by the sperm, caused by problem with the x or y chromosomes
Teratogens
any substance that effects development at any point in time, radiation, virus, drugs
possible outcomes:
low birth weight
- miscarriage
- prematurity are all risks
- infant death
- cancer and athsma
Prenatal Devlopment
stress can pass across the placenta, a virus like the flu can alter your DNA, weight gain, treat diabetes and preeclampsia ( high blood pressure)
Labor and Delivery
- High levels of stress hormone
- mom can start making milk before it is delivered and will continue as long as uses
- adrenaline and prolactin are secreted
- Babies have their first breathe from adrenaline, drain the fluid in lungs
- you need at least a 7 on this chart to be okay if you are a 6 or lower you need immediate medical attn.
Breech Birth
most babies turn down physically before birth, breeched, doctors can do it weeks before and is better than an emergency c section
- Anoxia ( oxygen deprivation) - they just need a ventilator and get their oxygen up
- potential for umb cord around neck
Newborn Reflexes
- sucking reflex- legit suck on anything they put in their mouth
- search for nipple when put on skin
- palmar grasp
- Moro reflex- baby tries to catch itself when
- tonic neck- they go captain morgan position
- babinski reflex- curling foot
- babies hold their breathe under water
brain development
lack of prefrontal cortex development in teenagers is why they make decisions as they do
White matter and grey matter in the brain bc of myelination
Romanian Orphanage Study
prove sensitive periods of brain development
- Kids don’t get individual attention and time so they compared kids who were adopted before 6 months old, they had good cognitive catch up
- after 6 months, there was serious issues
lower IQ scores
experience-expectant growth
where the brain is primed to learn
Piaget’s Sensorimotor Stage
reflexes lose by 6 months normally replaced w decisions
8 months learn object permanence by passing the A not B error test
Mental Representation with make believe play, violation of expectation test
attention, memory and categorization improves in infancy to toddlerhood
Vygotsky
3 zones of Proximal Development
- already developed
- already know
- zone of proximal development
- it is appropriate to learn that , w what you know
- cannot learn too hard
