Perspectives on Language
Development

Behavioral Approach (BF Skinner 1950’s)


Psycholinguistic/Syntactic Approach (Noam
Chomsky 1950-60’s)


environmental variables-parental input
we are prewired, born with a linguistic mechanism
Semantic/Cognitive Approach (Bloom 1970)



study on the meaning of an utterance instead if
syntax
semantic relation, the categories of meaning
children use
meanings are based on cognitive knowledge, not
syntax
5
Perspectives on Language
Development

Pragmatic Approach

Bruner, (1970’s)



early reflexive behaviors and gestures are refined
through repeated communicative interactions
languages learned in order to socialize and direct the
behavior of others
McLean and Snyder-McLean (1978-1999)


language is acquired and only develops if the child has a
reason to talk
A child’s language grows when he/she participants in
dynamic interactions with mature language-users
