[2] The 1990s were characterized by two major areas of research focus: linguistic theories of SLA based on Noam Chomsky’s Universal Grammar and psychological approaches such as skill acquisition theory and connectionism. This era also saw the development of new frameworks, including Processability Theory and Input Processing Theory ...
The Chomsky hierarchy in the fields of formal language theory, computer science, and linguistics, is a containment hierarchy of classes of formal grammars. A formal grammar describes how to form strings from a language's vocabulary (or alphabet) that are valid according to the language's syntax.
Chomsky's earlier work defines each lexical item as a syntactic object that is associated with both categorical features and selectional features. [10] Features—more precisely formal features—participate in feature-checking, which takes as input two expressions that share the same feature, and checks them off against each other in a certain ...
Chomsky had shown that the structural theories of language then prevalent could not explain the variety that is found in real communication. [11] In addition, applied linguists like Christopher Candlin and Henry Widdowson observed that the current model of language learning was ineffective in classrooms.
Universal grammar (UG), in modern linguistics, is the theory of the innate biological component of the language faculty, usually credited to Noam Chomsky.The basic postulate of UG is that there are innate constraints on what the grammar of a possible human language could be.

The language module or language faculty is a hypothetical structure in the human brain which is thought to contain innate capacities for language, originally posited by Noam Chomsky. There is ongoing research into brain modularity in the fields of cognitive science and neuroscience , although the current idea is much weaker than what was ...
A language L over the alphabet is context-free if and only if there exists . a matched alphabet ¯; a regular language over ¯,; and a homomorphism : (¯); such that = ().. We can interpret this as saying that any CFG language can be generated by first generating a typed Dyck language, filtering it by a regular grammar, and finally converting each bracket into a word in the CFG language.
