Different theories of learning and Acquisition
• Children do not learn a new language but naturally, acquire it through an inborn language device. This hypothetical device in the human brain is called a language acquisition device or LAD.
• All humans have a universal grammar (UG).UG means some grammar rule that is common for all languages.
• A child acquires vocabulary by language acquisition device and with inborn universal grammar produces sentences.
• It is a nativist theory of language.
Stephen Krashen’s Theory of Second language Acquisition:-
He basically suggests that how to acquire a second language (target language) rather than learning. Krashen gives five main hypotheses on second language acquisition.
1. Acquisition-learning hypothesis: Acquisition is better than learning. So create an environment for language acquisition.
2. Monitor hypothesis: After Acquisition of language when we learn a language in a formal way then we monitor the language.
3. Natural order hypothesis: We must acquire language rules in a natural way.
4. Input hypothesis: Comprehensible input helps in second language acquisition. The input level should be just above the level of the learner.
5. Affective filter hypothesis: If the factor
1.anxiety is high and
2.Motivativation and Self-confidence is low then
there is a mental block that prevents input to reach the language acquisition device(LAD).
