most cognitive developmentalists focus on ___
what are two different ways of viewing a child
some see them as small adults rather than developmentally challenged. some say they have innate patterns rather than blank slates.
two methods of study of cognitive development:
longitudinal- follow certain individual over time (less variation). cross-sectional- look at 3 diff ages at once- (less time)
importance of early experience:
sensitive and criticcal periods. ex. need of light.
but doesnt preclude lifetime development
paiget's first stage of cognitive development, lasting from birth to 2 years. schemata revolve around sensory and motor abilities.
sensorimotor period
chomsky and LAD say that talking will occur in this sequence of sensorimotor:
coo--babble--word--two word utterances
the ability to recognize that objects still exist when they're no longer in sight
object permanence (recognition of parents, fear of strangers)
this stage involves reflexes such as rooting and suckling, object exploration & permanence, and contingincies
paiget's second stage of cognitive development lasting from age 2-7, children begin to think symbolically, and often lack the ability to perform mental operations such as conservation
preoperational period
this stage involves egocentrism, animism, dreams/reality, use of symbols, transductive logic, and two word phrases
the ability to recognize that the physical properties of an object remain the saim despite changes in object appearance
law of conservation (ex. size glasses of milk)
the tendency to see the world from ones own unique perspective only; a characteristic of thinking in preoperational period
paiget's 3rd stage, age 7-11. children aquire the capacity to perform a number of mental operations but still lack the ability for abstract reasoning
concrete operational period
this stage includes reality from nonreality, conducts mental operations without observables, law of conservation, reversibility, language: passive = active
concrete operational period
paigets last stage, thought processes become adult like, and people gain mastery over abstract thinking.
formal operational period
this is the concept that one kind of operation can produce change and that another kind of operation can undo that change

qualitative steps in childs understanding (large)
