1. 2) INNATISM: IT’S ALL IN YOUR
MIND
Chomsky (1959) argues that behaviorism
cannot provide sufficient explanations for
children’s language acquisition for the
following reasons:
2. Chomsky (1959) argues that
behaviorism cannot provide
sufficient explanations for
children’s language acquisition
for the following reasons:
3. –Children come to know more
about the structure of their
language than they could be
expected to learn on the basis of
the samples of language they hear.
4. –The language children are exposed to
includes false starts, incomplete
sentences and slips of the tongue, and
yet they learn to distinguish between
grammatical and ungrammatical
sentences.
–Children are by no means
systematically corrected or instructed
on language by parents.
7. LAD: LANGUAGE ACQUISITION
DEVICE ( or BLACK BOX)
– It contains all and only the principles which are
universal to all human languages
(i.e.. Universal Grammar – UG).
8. If children are pre-
equipped with UG.
What they have to learn is
The ways in which their
own language make use
of those principles
9. children need
access only
to samples of
a natural
language
which serve
as a trigger
to activate
the device.
Once the
LAD is
activated
They
discover the
structure of
the
language to
be learned
By matching
the innate
knowledge of
basic
grammatical
principles (UG)
to the
structures of
the particular
language in the
environment.
10. CONCLUSION
• Children’s acquisition of grammatical rules
is guided by principles of an innate UG
which could apply to all languages.
• Children “know” certain things of the
language just by being exposed to a
limited number of samples.
11. Evidence used to support Chomsky’s
innatist position:
Virtually all children
successfully learn their native language
at a time in life
when they would not be expected
to learn anything else so complicated
(i.e. biologically programmed).
12. –Language is separate from
other aspects of cognitive
developments
(e.g., creativity and social grace)
and may be located in a different
“module" of the brain.
13. The language children are
exposed to does not contain
examples
of all the linguistic rules and
patterns.
14. Animals cannot learn
to manipulate a symbol system
as complicated as
the natural language
of a 3- or 4-year-old child.
16. The biological basis for the innatist
position:
The Critical Period Hypothesis (CPH) –Lenneberg:
• There is a specific and limited time period
(i.e., “critical period”) for the LAD to work
successfully.
• Only when it is stimulated
at the right time
18. Virtually every child learns language on a
similar schedule in spite of different
environments.
– Three case studies of abnormal language
development - evidence of the CPH
•Victor – a boy of about 12 years old
(1799)
•Genie – a girl of 13 years old (1970)
•Deaf signers (native signers, early
learners, vs. late learners)
