2. researches and focuses on the developing
knowledge and use of a language by
children and adults who already know at
least one other language.

3. Linguistic perspectives Universal
Grammar Monitor Theory

4. view on first language. According to Chomsky every
human being is biologically endowed with a
language faculty, the language acquisition device,
which is responsible for the initial state of
language development.

5. developed this theory in the 1970’s and
presented in terms of five hypotheses The
fundamental hypotheses is that there is a
difference between acquisition and learning

6. Cognitive Psychology Connectionism
Multidimensional Model

7. Behaviorism dominated psychology and education
in the twentieth century. The behaviorism theory
views the language as a set of structures and
acquisition as a habit formation

8. Cognitive psychologists hypothesized that
second language acquisition , like other
learning , requires the learner’s attention
and effort .

9. The Connectionism theory tries to explain
SLA in terms of mental representations and
information processing while rejecting the
innate endowment hypothesis.

10. Model Originally developed as a result of
studies of the acquisition of German word
order and later , on the basis of research
with L2 learners of English .

11. Perspectives Some theorists who work primarily within a
second language acquisition framework assume that a
great deal of language learning takes place through social
interaction , at least in part because interlocutors adjust
their speech to make it more accessible to learners.

12. It is argued that through dialogic
communication , learners jointly construct
knowledge and this knowledge is later
internalized by the individual.

13. In the 1970’s, a number of researchers began
to call attention to the fact that, although
the language produced by L2 learners did not
conform to the target language.

14. Second language acquisition studies
were based in L1 acquisition.

15. Is a subtle and evolving aspect of l2
development. Learners do not simply
transfer all patterns from L1 to L2 .

16. And Second Language Acquisition Instruction
can have a significant effect on L2
acquisition Instruction does not prevent
learners from going through developmental
stages. Certain kinds of instruction may
appear to alter developmental path of L2
acquisition.
