The Behaviourist Perspective
The Innatist Perspective
The Interactional/Developmental Perspective
Behaviourism
child’s language behaviour shaped by:
– quality and quantity of language heard
– consistency of reinforcement
The Innatist Perspective:It‘s all in your mind
It is seen as an explanation for the “logical problem of language acquisition“
What‘s that? The fact that children are come to know more
about the structure of their language than they could reasonably be expected to learn on the basis of the samples of language they hear
The Innatist Perspective: Noam Chomsky
Chomsky’s conclusion: Children’s minds are not blank slates to be filled by imitating language they hear in the environment
Hypothesis: Children are born with a specific innate ability to discover for themselves the underlying rules of a language system on the basis of the samples of a natural language they are exposed to
The Innatist Perspective:Example
Children hear false starts, incomplete sentences, and slips of tongue
Nonetheless they learn to distinguish between grammatical and ungrammatical sentences
John told Bill to wash himself. John told Bill to wash himself.
The Innatist Perspective Universal Grammar
If children are equipped with Universal Grammar, then what they have to learn is the ways in which the language they are acquiring makes use of these principles
The Innatist Perspective The Critical Period Hypothesis
Animals and humans are genetically programmed to acquire certain kinds of knowledge and skill at specific times in life
Difficult to apply this hypothesis for language acquisition because nearly all children are exposed to language (oral or gestural) at an early age
The Innatist Perspective Is there a Critical Period for Language Acquisition?
Neurological evidence Evidence from language acquisition of deaf
children Evidence from feral children Evidence from Down syndrome subjects
The Innatist Perspective CP Summary
There is little prospect of obtaining unambiguous evidence on the question of the possibility of beginning to acquire a L1 after any age posited as critical it would appear sensible to look at evidence concerning the continuation of language acquisition beyond the childhood years
“It is difficult to identify any point in the lifespan when the process of language development is truly complete.” Nippold (1998:1)
The Innatist Perspective Question 1
What is (according to N. Chomsky) “the logical problem of language acquisition“ and which theory is seen as an explanation for it?
The Innatist Perspective Answer 1
The innatist perspective is seen as an explanation for the “logical problem of language acquisition“
The “logical problem of language acquisition” is 1. The fact that children are come to know more about the structure of their language than they could reasonably be expected to learn on the basis of the samples of language they hear and 2. The question of how adult speakers come to know the complex structure of their first language on the basis of language that they actually hear
The Innatist Perspective Question 2
Why did E. Newport and her colleagues conclude that their study of deaf children learning ASL supports the hypothesis of a critical period?
The Innatist Perspective Answer 2
On tests focusing on grammatical markers (to indicate such things as time and number; these markers are expressed through specific hand or body movements), the Native group (who were exposed to ASL from birth) used the forms more consistently than the Early group (who began using ASL between 4-6 years of age). This group, in turn, used them more consistently than the Late group (who began learning ASL after age twelve)
Interactionist/Developmental Perspectives
Learning from inside and out Language Acquisition seen as the ability to
learn from experience Interactions Focus on interplay between innate learning
ability & environment
Interactionist/Developmental Perspectives
Jean Piaget– children‘s interactions with objects & people– development of cognitive understanding
Lev Vygotsky– children‘s interactions with other children & adults– Zone of Proximal Development (ZPD)
Interactionist/Developmental Perspectives
Cross cultural research
– children‘s learning environments in different cultural communities
– child-directed speech– not universal
Interactionist/Developmental Perspectives
The importance of interaction
– Jim– deaf parents– no sign language
Interactionist/Developmental Perspectives
Connectionism
– Language acquisition does not require “module of the mind“
– Connections between words and phrases + the situation in which they occur
Interactionist/Developmental Perspectives
What characterizes child-directed speech?– slower rate of delivery– higher pitch – more varied intonation– shorter, simpler sentence patterns– stress on key words– frequent repetition– paraphrase
Interactionist/Developmental Perspectives
Explain the difference between Piaget‘s and Vygotsky‘s point of view
