piaget’s 4 stages of cognitive development
sensorimotor, preoperational, concrete operational, formal operational
sensorimotor stage
0-2 years, infants experience their world through their senses and motor activities. have object permanence
object permanence
awareness that objects continue to exist even when not perceived. begins at 8 months
preoperational stage
2-6/7 years, child learns to use language but does not yet comprehend the mental operations of concrete logic. lacks conservation, has egocentrism, and the theory of mind
conservation
the child doesn’t understand that properties such as mass, volume, and number remain the same even if the object’s form changes
egocentrism
inability to take another’s point of view
theory of mind
people’s ideas about their own and others’ mental stages
concrete operational stage
6/7-11 years, children gain the mental operations that enable them to think logically about concrete events
formal operational stage
12+ years, people begin to think logically about abstract concepts
lev vygotsky
russian developmental psychologist who said children learn best by interacting with others
attachment
an emotional tie; survival impulse that keeps infants close to their caregivers
critical period
an optimal period early in life when exposure to certain stimuli or experience produces normal development
imprinting

lawrence kohlberg
harvard psychologist who researched moral development. proposed 3 stages of development; preconventional, conventional, and post conventional
preconventional level
the first stage of moral development. from birth-9 years. moral values reside in a person’s own needs and wants. characterized by a desire to avoid punishment or gain reward
conventional level
second stage of moral development from 9-19 and beyond. morality of law & social rules. moral judgments are made to get approval by pleasing & helping others and being good citizens
post conventional level
third stage of moral development. adolescence to beyond. morality of the abstract. rules agreed on by the whole society are accepted as binding, yet looked on as subject to change (ex. thanos)
cultural bias
a criticism of kohlberg’s theory. collectivist cultures see morality as tied in with the good of the community, not to some personal standard
