Abstract
The Behavioral theory says that learning is all about change in human behavior which a person achieves through stimuli and response. Language is also a behavior that is obtained as a non-linguistic behavior through stimulus and response. On the other hand, cognitive theory says that learning takes place from a set of mental cognitive processes like understanding, attention, receiving information, preparing and processing it in sync with interaction with the surrounding environment, similarly it considers that the second language acquisition also depends on complex mental processes which can be controlled with conscious learning of language grammar. In view of the conflicting views of educationists and linguists in effective learning and teaching of the language, we must ask what the most appropriate opinion of these views is. This topic is worth researching to get the positives out of both theories by the comparative study of these two theories. So that learner and teacher can choose the best strategies for learning or teaching the language. The researcher relies on his research on the comparative and descriptive approach in this study.
