Development Flashcards
developmental psychology
studies physical, cognitive, and social changes throughout life span
monozygotic twins vs. dizygotic twins
identical vs. fraternal
embryo
2-9 weeks
fetus
9 weeks to birth
teratogens
agents that can harm the embryo or fetus during prenatal development
fetal alcohol syndrome
physical and cognitive abnormalities in children caused by heavy drinking during pregnancy
rooting reflex
when touched on the cheek, baby will turn head in direction of touch and open mouth
moro reflex
when startled baby will fling out limbs then pull them back in
babinski reflex
when baby’s foot is stroked, toes will fan out then curl
habituation
decrease in responding with repeated stimulation (infants get bored, look away sooner)
pruning
lose unused connections between neurons
maturation
biological growth processes that enable orderly sequential changes in development resulting from genetic signals
schema
concept or framework that we use to organize and interpret information
Piaget’s 2 proposed processes of schemas
assimilation and accomodation
assimilation
interpreting new object/experience in terms of existing schemas
accomodation
alter pre-existing schemas to incorporate new info
Piaget’s stages of cognitive development
sensorimotor, preoperational, concrete operational, formal operational
sensorimotor stage
birth to 2 years; experience world through senses; stranger anxiety and object permanence
object permanence
awareness that things continue to exist even when they cant be perceived, acquired around 8-9 months
preoperational stage
2 to 6/7 years; representing things with words and images, using intuition rather than logical reasoning; pretend play, egocentrism
thinking in preoperational stage is
1 dimensional, lack conservation
conservation
prinsiple that properties remain same even when there are changes in shape/form of objects
egocentrism
inability to see another’s perspective
theory of mind
people’s ideas about their own and other’s mental states
concrete operational stage
age 7 to 11 years; thinking logically about concrete events, grasping analogies and performing arithmetical operations; has conservations
formal operational stage
abstract reasoning, abstract logic, potential for mature morals
criticisms of piaget’s stages
piaget underestimated kid’s abilities, stage theories flawed because development is continuous
Vgotsky
kids think in words and use them to problem solve - how they learn in the context of social commmunication - scaffolding
scaffolding
other students can help pull a lower level kid up to their level
kohlberg’s stages of moral development
preconventional morality, conventional, post-conventional
level 1 preconventional morality
right/wrong determined by reward/punishment
level 1 stage 1
punishment and obedience - wrong behavior
level 1 stage 2
rewards, self interest - right behavior
level 2 conventional morality
views of others matter, avoid blame, seek approval
