In Psychology

Noam Chomsky developed the theory of Universal Grammar, which said that humans have a biological aptitude to acquire language. His theory has helped develop the modern academi…c field of Linguistics and also Psychology as it deals with language and language acquisition. (MORE)

1,In computer science, a formal grammar is said to be in Chomsky normal form if all of its production rules are of the form: where A, B and C are nonterminal symbols, α …is a terminal symbol (a symbol that represents a constant value), S is the start symbol, and λ is the empty string. Also, neither B nor C may be the start symbol. Every grammar in Chomsky normal form is context-free, and conversely, every context-free grammar can be efficiently transformed into an equivalent one which is in Chomsky normal form. With the exception of the optional rule Sλ (included when the grammar may generate the empty string), all rules of a grammar in Chomsky normal form are expansive; thus, throughout the derivation of a string, each string of terminals and nonterminals is always either the same length or one element longer than the previous such string. The derivation of a string of length n is always exactly 2n − 1 steps long. Furthermore, since all rules deriving nonterminals transform one nonterminal to exactly two nonterminals, a parse tree based on a grammar in Chomsky normal form is a binary tree, and the height of this tree is limited to at most the length of the string. Because of these properties, many proofs in the field of languages and computability make use of the Chomsky normal form. These properties also yield various efficient algorithms based on grammars in Chomsky normal form; for example, the CYK algorithm that decides whether a given string can be generated by a given grammar uses the Chomsky normal form. The Chomsky normal form is named after Noam Chomsky, the US linguist who invented the Chomsky hierarchy. 2,In computer science, to say that a context-free grammar is in Greibach normal form (GNF) means that all production rules are of the form: where A is a nonterminal symbol, α is a terminal symbol, X is a (possibly empty) sequence of nonterminal symbols not including the start symbol, S is the start symbol, and λ is the null string. Observe that the grammar must be without left recursions. Every context-free grammar can be transformed into an equivalent grammar in Greibach normal form. (Some definitions do not consider the second form of rule to be permitted, in which case a context-free grammar that can generate the null string cannot be so transformed.) This can be used to prove that every context-free language can be accepted by a non-deterministic pushdown automaton. Given a grammar in GNF and a derivable string in the grammar with length n, any top-down parser will halt at depth n. Greibach normal form is named after Sheila Greibach. (MORE)

Noam Chomsky developed a theory of Generative Grammar during the 1950s and later. Before Chomsky Grammar had only described language - which is useful for learning a lan…guage, but tells you nothing how about language works inside the mind. Chomsky's Generative Grammar gave scientists ideas about how humans create language - and therefore how we think. Most of Chomsky's ideas have proved to be generally correct, and a new science - Cognitive Science - has grown up from Chomskyan theories. Computer scientists also found Chomsky's ideas about language structure useful, and computer languages based on Chomskyan principles (Pascal, C#, Prolog) are much more powerful than the older pre-Chomskyan languages (Fortran). A good introduction to Chomskyan language analysis techniques can be found in Stephen Pinker's books - especially 'The Language Instinct'. Chomsky is probably the most important grammarian since Quintilian (in Roman times) and may be one of the 20th Century's most important theoretical scientists. (MORE)

brief answer: his linguistic theories are premissed upon an innate capacity for language (we're hardwired to communicate with words). This is in opposition to empirici…sm, which usually posits no a priorimental faculties. If you're not an empiricist, you're a rationalist (or a kantian, which is really where chomsky takes his cues). hope this helps. (MORE)

20c + 5 = 5c + 65 Divide through by 5: 4c + 1 = c + 13 Subtract c from both sides: 3c + 1 = 13 Subtract 1 from both sides: 3c = 12 Divide both sides by 3: c = 4
