In (1957) in the book BF Skinner - one of the pioneers of behaviorism - proposed one of the first scientific explanations concerning the topic of language acquisition; his theory states that children learn language based on behaviorist reinforcement principles by associating words with meanings. However, Skinner's approach was massively criticized by Noam Chomsky (1972), considered the world's most famous linguist to date, and his theory that he proposed in his book Language and mind. This theory, which serves as a counterargument to Skinner, states that there are innate structures in our brain that he called a language acquisition device (LAD) which presupposes that children have a propensity to organize what we hear in their correct fields and even form original sentences while missing. all the information necessary to do so.

Chomsky proposed a theory that explains how the mind develops during language acquisition. Chomsky (1972) Nativist theory requires that children have an innate capacity to acquire language. There are certain rules in the human brain since birth. They adapt very quickly to the language because they have universal grammar. Chomsky demonstrates that children know the basics of language, but simply don't have enough vocabulary to begin speaking. And this is what he begins to acquire by observing others. Its hypotheses that there is a basic grammar in our brain called the LAD language acquisition device. Those that facilitate language learning.Research CorpusThe research paper will focus on the common features between the different corpora in order to serve the purpose of presenting Chomsky's (1972) nativist theory with evidence provided. Acquiring a first language is such a simple process, with the innate ability stating that any native language can be learned in the same way, because all children have a common basic (universal) grammar that helps them to achieve some understanding throughout their first language learning training.
