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.
developed this theory in the 1970’s and presented in terms of five hypotheses The fundamental hypotheses is that there is adifference between acquisition and learning
Cognitive Psychology Connectionism Multidimensional Model
Behaviorism dominated psychology and educationin the twentieth century. The behaviorism theory views the language as a set of structures and acquisition as a habit formation
Cognitive psychologists hypothesized that second language acquisition , like otherlearning , requires the learner’s attention and effort .
The Connectionism theory tries to explainSLA in terms of mental representations and information processing while rejecting the innate endowment hypothesis.
Model Originally developed as a result ofstudies of the acquisition of German word order and later , on the basis of research with L2 learners of English .
Perspectives Some theorists who work primarily within a second language acquisition framework assume that agreat 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.
It is argued that through dialogiccommunication , learners jointly construct knowledge and this knowledge is later internalized by the individual.
In the 1970’s, a number of researchers began to call attention to the fact that, althoughthe language produced by L2 learners did not conform to the target language.
Second language acquisition studies were based in L1 acquisition.
Is a subtle and evolving aspect of l2development. Learners do not simply transfer all patterns from L1 to L2 .
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.
