The Man<br />December 7, 1928: Chomsky was born.<br />From the age of two, he spent ten years in a progressive Deweyite school in Philadelphia, where there was a congenial emphasis on individual creativity.<br />He attended the University of Pennsylvania where he met Zellig Harris<br />1949: He graduatedwith a BA. His thesis was about Modern Hebrew. He enteredgraduateschool.<br />1951: He became one of the Society of Fellows at Harvard, from where he moved to the Massachusetts Institute of Technology (MIT) in 1955.<br />He has been repeatedlyjailed for politicalactivism. (Smith, 2004). <br />He has been influenced by  a large variety of thinkers, philosophers, politicians and linguists. <br />Many compare him to Bertrand Russel.<br />
  11. 11. Chomsky: …. The Revolution<br />Chomsky made a resurrection to innateness.<br />He has returned the mind to its position of preeminence in the study of humankind.<br />The ideathat a substantial part of our knowledge is genetically determined came forward.<br />‘‘He has shown that there is really only one human language: that the immense complexity of the innumerable languages we hear around us must be variations on a single theme. He has revolutionizedlinguistics, and in so doing has set a cat among the philosophical pigeons.” (Smith, 2004: 16).<br />Since 1957, syntax and cognition have become the pace-maker in theoretical linguistics rather than phonology. <br />
  12. 12. Background <br /><ul><li>Before the 1960s, the structuralist Model was very dominant. It was simply descriptive of the different levels of production, namely: phonology, morphology, syntax and semantics.
  13. 13. It did not provide any model or frame work for understanding how the actual learning takes place.
  14. 14. In the late 1950s, Skinner constructed his cognitive learning model: behaviorism which correlates with the notion.</li></ul> Stimulus -> response-> reinforcement<br /> and habit formation<br /><ul><li>According to Skinner, children learn the language by imitating and repeating and the mind is a blank slate at birth.</li></li></ul><li>Chomsky’s Critique to Skinner’s Model<br /> Although children hear only a finite number of sentences, they are able to produce an infinite number of possible sentences with no previous formal training or correction.<br />
  15. 15. Poverty of the stimulus<br />Chomskyan syntax: more complex than people had previously thought syntax to be!<br />The grammar of a sentence can’t be deduced from its surface form<br />The schoolchildren were difficult to teach<br />The schoolchildren were eager to learn<br />So environmental language data is insufficient: grammar can’t be learned from it<br />
  16. 16. Chomsky’s Critique to Skinner’s Model<br />Constraints and principles cannot be learnt:<br /><ul><li>Children learn their first or second language at an early age.
  17. 17. They learn, for example, single word formation at the age one, and learn the basic grammar around age six.
  18. 18. At this age, no one has the cognitive ability to understand the principles of grammar as a system, but because some innate capacity, is still capable of using it.
  19. 19. Put it differently, children do not know anything about grammar or syntax but still they can produce grammatical sentences in most of the time.</li></li></ul><li>Chomsky’s Critique to Skinner’s Model<br />3. Patterns of development are universal.<br />When children develop their language, they learn the various aspects of language in a very similar order.<br />If children only learned what they are taught, the order of what they learned would vary in different environments.<br /> e.g.: Brown Model 1973:<br />
  20. 20. Creativity<br />Language is CREATIVE<br />We can produce and understand an infinite range of novel grammatical sentences<br />Children do not imitate a fixed repertoire of sentences<br />Chomsky: creativity is not explicable if language is learnt just from the environment<br />
  21. 21. Degeneracy of the data<br />The child’s language data is degenerate<br />Ungrammatical utterances are frequent and are not marked out as “wrong”<br />Therefore it is impossible to deduce the grammar of a language, if your only input data is utterances from the environment<br />
  22. 22. Language Acquisition Device<br /><ul><li>L.A.D is a function of the brain that is specifically for learning language. It is an innate biological function of human beings just like learning to walk.
  23. 23. L.A.D plays two roles in Chomskyan theory:
  24. 24. 1. It accounts for the striking similarities among human languages.</li></ul> e.g.: the similarity in using relative clause constructions from English, French and Arabic.<br /><ul><li>A. English: a- the man that I saw was your brother</li></ul>b- I read the book that you read.<br /><ul><li>B. French: a- L’homme que j’ai vu était ton frère.</li></ul>b- J’ai lu le livre que tu as lu.<br /><ul><li>C. Arabic : a- r-raʒulu l-ladi: ra ?eitkanaxuk.</li></ul>b- 9ara?to lkita:b l-ladi: 9ara?ta.<br /><ul><li>2. It accounts for the speed, ease and regularity with which children learn their first language.
  25. 25. If the sequence order is the same in all children, it is then quite normal to speak about language universals.</li></li></ul><li>Evidence from Creoles<br />Pidgin: simple language that arise in contact situations<br />Creole: a fully complex language descended from a pidgin<br />The grammar of a Creole is created by children as they learn it<br />This is evidence that this grammar comes from some innate source<br />
  26. 26. Universals<br />Human languages exhibit remarkable similarities or principles. These patterns are called universals.<br />We can find these similarities on many linguistic levels:<br />1. Phonological universals: Consonants, for example, are distinguished also according to the location of their production, that is, after the various organs of the vocal tract. With the help of this detailed information we can now refer to every consonant by its location and manner of articulation; [f], for example, is a voiceless, labiodentals fricative.<br />2. Syntactic universals: Also, most of existing languages have verbs, nouns, adjectives and pronouns.<br />3. Semantic universals: One semantic universal regards our notion of color. There exist eleven basic color terms: black, white, red, green, blue, yellow, brown, purple, pink, orange, and grey.<br />
  27. 27. Language as Rule-governed System<br /><ul><li>We may need to look at these examples which in some way show that the speakers of language often behave as if their language is rule-governed.
  28. 28. The thought of those poor children were really …WAS really...bothering me.
  29. 29. Even though they told me to, I didn’t sit down and wasn’t quit…Was quite …I mean I didn’t sit down and I wasn’t quite.
  30. 30. Ze pound are worthless = the pound is worthless.
  31. 31. The speaker who is ready to correct themselves and others gives evidence that there is a right and wrong way of saying things. This assumption that speakers know the grammar of a language is a claim that these grammars are psychologically real. The question that is to be raised here is: how do we come up to know this knowledge of language?</li></ul>Claiming that language is rule-governed system is like claiming that language is definable in terms of grammar.<br />
  32. 32. Intuitions<br /><ul><li>Linguistic knowledge of language lies well beyond the level of consciousness. One way of investigating this knowledge is to ask speakers of a language for their judgments about sentences of their language: not directly but indirectly.
  33. 33. Ask them, for example, about the grammaticality or ungrammaticality of certain sentences.
  34. 34. There are some difficulties in deciding on how much reliance should be put on speakers’ intuitions.</li></ul> e.g.: a- I like Indians without reservations.<br /> b- I have no reservations in my liking for Indians.<br /> c- I like Indians who don’t live on reservations<br /><ul><li>this is to argue a certain distinction should be made between the speaker’s perceptual or understanding abilities (performance) and his actual knowledge of the language performance.</li></li></ul><li>Competence and Performance<br /><ul><li>“competence is knowledge of language. That part of our knowledge which is exclusively linguistic. It includes knowledge of the vocabulary, of phonology, of syntax, and of semantics. The part of such knowledge which is different from language to language is learnt; the part which is universal is innate.”
  35. 35. “Performance is the use of language in speaking and understanding utterances is linguistic performance. Performance is dependent on one’s linguistic knowledge (competence) and in part on non-linguistic knowledge of an encyclopedia or cultural kind, as well as on extraneous factors as mood, tiredness and so on”</li></ul>Neil, S, Dreidre, W.(1990) Modern Linguistics<br /><ul><li>The distinction between performance and competence (grammaticality and acceptability) is distinction between sentence and utterance.</li></ul> a. Sentences are abstract objects which not tied to a particular context, speaker or time of utterance. They are tied to a particular grammar.<br /> b. Utterances are datable events, tied to a particular speaker, occasions, and context.<br />
  36. 36. Competence and Performance<br /><ul><li>There are some utterances which could never be a grammatical sentence, but still they are acceptable.
  37. 37. e.g.
  38. 38. John’s being a real idiot-I suppose cela va sans dire-kolshi 3arafha.
  39. 39. On the other hand, there some grammatical sentences which can never be realized as fully acceptable utterances because their semantic, syntactic or phonological content.
  40. 40. e.g.: </li></ul> 1.we finally sent Edinburgh man, for for four Forfar men to go would have seemed like favoritism.<br />2. If because when Mary came in John left Harry cried, I’d be surprised.<br /> 3. The colorless green idea sleeps calmly in my head.<br />
  41. 41. Scientific Evaluation of Grammar<br />žInadequacy of corpora lead Chomsky to reconsider the theoretical approach to data analysis.<br />A linguistic theory explains rather than describes grammars:<br />Observationally adequate: It accounts for all the observed (corpus/performance) data. <br />Descriptively adequate: It accounts for  <br /> observations and acceptability judgements (competence), and generalizations . <br />Explanatorily adequate: It accounts for observations, acceptability, and language acquisition.<br />
  42. 42. Transformationalgenerativegrammar<br />What is a sentence? A hierarchicaly organized structure of words that maps sound to meaning and vice versa.<br />What is grammar? A set of rules. It is a cognitive structure or the part of the mind that generates and understands language.<br />What is syntax? The scientific study of sentence structure. It is the psychological or cognitive sentence structure in the mind.<br />Sentences consist of structured words.<br />
  43. 43. Phrase Structure Grammar<br />We speak about the language in terms of phrases and constituents.<br />Phrase structure doesn’t account for all the language.<br />Chomsky remarks that: ‘‘ notions of phrase structure are quite adequate for a small part of the language and that the rest of the language can be derived by repeated application of a rather simple set of transformations to the strings given by the phrase structure grammar.” (qt in Smith, 2004).<br />Constituent:  A sentence embedded into another <br />Matrix:  A sentence into which another is embedded. <br />This grammar is both transformational and generative.<br />
  44. 44. Transformations<br />H. Robins in his General Linguistics describes a transformation as ‘‘a method of stating how the structures of many sentences in languages can be generated or explained formally as the result of specific transformations applied to certain basic sentence structures.” (qt in Smith: 2004). <br />žThe kernel is the basic phrase from which transformations start. <br />
  45. 45. Deep structure surface structure<br />Deep structure: the aspect of syntactic structure operated on by semantics for the purpose of semantic interpretation <br />Surface structure: the aspect of syntactic structure operated on by phonology for the purpose of phonetic interpretation. <br />
  46. 46. The Generative Aspects<br />A grammar is to generate all and only the grammatical sentences of a language.<br />The grammar must be so designed that by following its rules and conventions we can produce all or any of the possible sentences of the language.<br />To generate is to predict or specify precisely what are the possible sentences of the language. <br />Thus a grammar should `generate', `specify', and `predict' sentences such as: <br />He is waiting for the bus. <br />but not * waiting he is for the bus, or * He the bus is waiting for.<br />There is concern with potential utterances. <br />
  47. 47. To generate a sentence like `A man read the book’<br />1. S---------NP + VP <br />2. VP---------V + NP <br />3. NP---------D + N <br />4. V--------- read <br />5.Det---------a, the <br />6. N---------man, book <br />If we apply the rules in sequence, we generate the following strings successively: <br />S <br />NP + VP <br />NP + V + NP <br />Det + N + V + Det + N <br />Det + N + read + Det + N <br />A man read the book. <br />We can indicate optional elements by the use of brackets. Thus the string can be rewritten as: NP---Det (adj) + N. <br />We can now generate such sentences as:<br />A tall man read the short book. <br />
  48. 48. Infinity<br />Any corpus has a finite number of sentences, no matter how large, yet a language consists of an infinite number of sentences. This infinity is a result of `recursion‘: We can apply the same linguistic device over and over again. For example, <br />Those are the books that Rachid bought. <br />Those are the two thinkers who wrote the books that Rachid bought. <br />Those are the cars that belong to the two thinkers who wrote the books that Rachid bought. <br />We can contrive ad infinitum.<br />
  49. 49. Implications for education<br /><ul><li>Language acquisition and learningbecomedifferentiated.
  50. 50. A child learning language simply does not have the enough evidence to enable it to learn the relevant principles from scratch.
  51. 51. Languagedevelopswith the mind.
  52. 52. Nature and nurture go together.
  53. 53. Mental lexicon, mental structures and andschematacanenhancelanguagelearning.
  54. 54. TPR wanes down.</li></li></ul><li>Conclusion<br />It isdifficult to summarize the vast output and prolificcareer of Chomsky. . He has revolutionized modern linguistics as well as other disciplines including Computer Science, psychology , philosophy , anthropology and politics .<br />His students have contributed vividly to many other areas<br />Chomsky’s most recent work includes his continued contributions to linguistics (in particular new developments in the Minimalist Program), his further discussion on evolution, and his extensive work on the events of September 11, 2001 and theiraftermath.<br />
