-study the development of language, thought, symbols and the social use of language
basic perceptual units of language
sounds made in a language
phonetic expansions
babies make all sounds in all languages
3 stages of Phonetic Expansions
-phonetic contraction

B.F. Skinner
-children aquire syntax through operand conditioning
-children use words and get positive result from adult
-said children learn principles for language because they are inate
-language acquistion device (LAD)
4 reasons inflections are inate (according to chompsky)
-children learn language no matter what language from 18months to 2 years
-kids overregularize language- children will appy regular rules of inflection to irregualar examples(goose-gooses)
-use telegraphic speech-make simple sentances with only critical words(mommy go work)

Developmental Psych
study of how we change
studied cognitive development in children and how they see the world
-first to say that younger children think different from older children
4 stage model of cognitive development (piaget)
-sensory-motor period
-preoperational period
-concrete operations
-formal operational period
Sensory Motor period
-0-2 years

-7-12 years
-thought becomes logical, but it is tied to real world events (mathematical operations)
-no abstract thoughts
Formal Operational Period
-12 and up
-abstract thought from hypothetical situations
-algebra, scientific method
-systematically solving problems (if ->then)
2 Criticisms of Piaget
-children show variations of cognitive abilities ealier then piaget believed (children are also no as egocentric as piaget believed (teach younger children))
-babies are more mentally active and alert then piaget thought (learn what mom looks like 1-2 days old)
Moral Devleopment
Piaget and Kohlberg
-cognitive psych
-how we think and make decisions about morality
-how children acquire and understand rules

-age 6-first real understanding of rules, but are taken to extreme, rules come from source outside themselves(god, police), harsh penalties to those who break rules, difficulty distinguishing between intention and outcome
-age 10- kida are more flexable with rules
cross-sectional study
study differnt individuals at different ages at the same time
logitudinal study
study the same individuals over time as they age
heinz dilemma
