Development Flashcards
bronfenbrenner’s ecological model
microsystem - immediate envt
mesosystem - interactions between components of microsystem (e.g. fam factors on school)
ecosystem - broader environment that affect child (parents work)
macrosystem - cultural beliefs
chronosystem - occur over lifespan (LT effects of SES)
Rutter’s indicators
predictors of child psychopathology: marital discord, low SES, large family size, parent criminality, maternal psychopathology, placement of child outside of home
niche picking
children seek out experiences that are consistent with their genetic predisposition
stages of prenatal development
germinal (2 weeks- ovum –> zygote)
embryonic (3 - 8 wks)
fetal (9 wk - birth)
dominant gene disorders
Huntingtons
Recessive gene disorders
cystic fibrosis
sickle cell
Tay Sachs
phenylketonuria
Chromosomal abnormalities
Down syndrome
Klinefelter
Turner (females with single x - short, webbed neck..)
brain development
brain is 25% of adult weight at birth
2 yo - 80% of adult weight (d/t increase in connections between neurons and formation of glial cells - myelination )
16 yo- full adult weight
neurogenesis
brain compensates for neuronal loss by forming new synaptic connections and neural pathways and new neurons in hippocampus
moro (startle) reflex
flings arms and legs outward and then toward body in response to a loud noise or loss of physical support
perception in newborns:
__ in 1-4 mo
__ 12 wks +
___ 5.5 to 12 mo
sucking
reaching
head turning
(heart rate and respiration for all)
vision
least well developed at birth
6 mo - visual acuity is almost that of adult
auditory localization
orient toward direction of sound
evident shortly after birth, disappear bt 2 and 4 mo and then reappear during rest of first year
few days after birth - can distinguish between a and i; by 2-3 mo, bt similar consonant sounds
early maturation for boys
benefits: popularity, athletic
bad: dissatisfaction with body image, increased risk for drug /alcohol use, delinquency, depression
early maturation for girls
bad: poor self concept, unpopular, dissatisfied, low academic achievement, increased risk for sex, drug, alcohol, depression, and eating disorder
late maturing - still not great but better academically
visual changes
after age 65, most ppl have problems that interfere with reading, driving, etc
sexual activity in late adulthood
similar to that of earlier adulthood
piaget’s adaptation
resolves disequilibrium
assimilation
incorporation of new knowledge into existing scheme
accommodation
modification of existing schemes to incorporate new knowledge
Piaget stages of cognitive development
birth/toddler: sensorimotor (object permanence)
preschool: Preoperational (learn thru language, symbols (pre causal reasoning, magical thinking, animism, irreversibility, centration- focus on most noticeable features)
School: Concrete operational (mental operations; logical rules, Conservation thru horizontal decalage - gradual gaining of conservation abilities)
Adolescent+: Formal Operational (think abstractly; egocentrism, personal fable, imaginary audience)
Information processing theories
increasing information processing capacity and efficiency
focus on specific cognitive domains and view cognitive ability as task specific
Vygotsky’s sociocultural theory
all learning as socially mediated; cognitive development is first interpersonal and then intrapersonal
zone of proximal development
scaffolding
early recognition and recall memory
3 mo - can recognize up to 24 hr later
6-12 mo - can recall series of events
retention function
greater recall of recent events
reminiscence bump
greater recall of events that occurred from 10-30 yo
effects of age on memory:
increasing age has negative impact on ___ rather than __
older adults have greatest declines in ___ followed by ___
___ is more affected by age than ___ or ___
explicit v implicit
recent LT memory (secondary memory; working memory
episodic memory; semantic or procedural
age when children use memory strategies regularly
9 or 10
nativist approach to language development; advocated for by ___; he thought we had a ____, which :
biological mechanisms, universal pattern of language development
Chomsky; innate language acquisition device (LAD) - makes it possible to acquire knowledge just by being exposed
