The document discusses three domains of language development - syntax, semantics, and pragmatics - and three theories of language acquisition: learning theory, nativist theory, and interactionist theory. Learning theory proposes that language is acquired through reinforcement of behaviors, nativist theory argues aspects of language are innate, and interactionist theory views language acquisition as an interplay between biological predispositions and social/environmental factors.

Syntax, Semantics, & Pragmatics
 Three Theories of Language Development
1. Learning Theory
2. Nativist Theory
3. Interactionist Theories

3. Introduction
 When we communicate successfully, we do so
because we are able to do at least four different
things.
 First, we need to be able to perceive and
produce the sounds that make up a language
and convey meanings to other people.

4.  Second, we need to know what the words of a
language mean.
 Third, we need to know how to put these words
together in grammatically appropriate ways such
that others will understand us.
 Fourth, we need to know how to effectively use
our language to communicate with others.

5.  Psychologists who study language refer to each
of these processes by different names.

6.  How we produce meaningful sounds is the study
of phonology.
 Semantics is the study of word meaning and
how we acquire a vocabulary.
 The study of grammar (or syntax) refers to how
we learn the rules of a language.
 Pragmatics is the study of how we use language
to achieve communicative goals.

7. Theories of Language
Acquisition

8. Theories of Language Acquisition
1. Behavioural –( Learning) Theory

9.  Skinner argued that children learn language as
parents selectively reward or punish only those
behaviors which they recognize as appropriate,
grammatically correct utterances.
 Bandura argued that language learning takes place
primarily by processes of observation &
imitation. Simply put, children overhear
language being used and they imitate the behavior
of these models.

10.  Learning theory has been criticized on a number of counts.
 It is simply not possible for parents to reinforce or punish
all of the possible utterances a child will use.
 Studies of parent-child interaction show that parents
reward grammatically incorrect utterances that are truthful.
 The language that children hear contains too few examples
for them to learn the correct rules (poverty of the
stimulus argument).

11. 2. Nativist Theory

12. 2. Nativist Theory
 The nativist view of language development is traced back
to the work of Noam Chomsky (1957).
 Chomsky argued that language is the product of an
unlearned, biologically-based, internal mental structure.
 Because the rules which underlie a language are too
complex to be acquired by children in a few short years,
some aspects of language must be innately specified.

13.  In short, many aspects of language are not
learned but are a part of our biological
endowment.

14.  Nativist theory has been criticized on a number of counts.
 Linguists have failed to specify the nature of universal
grammar. Many linguists have speculated that this may not
be possible.
 Grammar is not learned as rapidly as one might expect if a
great deal of innate knowledge is assumed.

15. 3
 Interactionist Theory

16. 3.
 Interactionist theories are concerned with the
interplay between environmental & biological
factors in the process of acquiring language.
 Interactionists tend to view children as having a
strong biological predisposition to acquire a
language.

17.  However, in contrast to nativists, interactionists
stress the importance of both the social support
that parents provide the young language learner,
as well as the social contexts in which language-
learning child is instructed.

18.  Bruner (1983) argues parents provide their
children a language acquisition support system
or LASS.
 The LASS is a collection of strategies that parents
employ to facilitate their children’s acquisition of
language.

19.  Another strategy is called infant-directed speech or
‘motherese’. When using infant-directed speech, parents
speak in a higher pitch, stress important words, and talk
more slowly to their infants.
 Very young infants show a clear preference for infant-
directed speech. Gets an infant’s attention & increases the
chances of their understanding the message.

20.  Criticisms of Interactionist Perspectives
 deVilliers & deVilliers (1992) suggest that parents
rarely offer their children direct feedback on the
appropriateness of their grammar.
 Linguistic & social practices vary widely across
cultures. Some cultures do not use anything like
the practices described above and yet, their children
still learn language at a similar rate to Western
children.

21. Conclusions
 Each of the three theoretical perspective adds
something to the study of human language.
 Learning theory provides some thoughts on
plausible mechanisms that might underlie the
acquisition of at least some facets of human
language.

22.  Nativist theory highlights the fact that now all
aspects of a language can be learned in the time
that humans typically do and thus, that an innate
language mechanism must be a part of our
equipment.
 Interactionist theories highlight the important
role of the social environment and the important
role social input has in structuring our language-
learning.
