Definition of UG A set of principles and parameters that constrain all human languages. Universal Grammar UG is par t o f the human gene tic in Second Language Acquisition endowment and is encoded in the Language Acquisition Faculty (LAF). 2 And what is the LAF? Principles and Parameters of UG “An innate component of the human mind A principle of UG is a statement that is that yields a particular language through true for all human languages. interaction with presented experience, a For example: device that converts experience into a The principle of structure dependency system of knowledge attained: knowledge A parameter must be set according to the of one or another language.” requirements of the language being acquired. For example: Chomsky (1986) The null subject parameter 3 4 Principle of Structural Dependency Principle of Structural Dependency Grammatical rules do not depend on the Subject-auxiliary inversion in English linear ordering of the words in the – She will laugh. sentence, but on how these words are structured within constituents of specific types. 5 6 1 Principle of Structural Dependency Principle of Structural Dependency Subject-auxiliary inversion in English Subject-auxiliary inversion in English – She will laugh. – She will laugh. – Will she laugh? – Will she laugh? – The student who is takitakingng good notes will get an A. 7 8 Principle of Structural Dependency Principle of Structural Dependency Subject-auxiliary inversion in English Subject-auxiliary inversion in English – She will laugh. – She will laugh. – Will she laugh? – Will she laugh? – The student who is takitakingng good notes will get – The student who is takitakingng good notes will get an A. an A. – Is the student who taking good notes will get – Is the student who taking good notes will get an A? an A? 9 10 Principle of Structural Dependency Principle of Structural Dependency Subject-auxiliary inversion in English Subject-auxiliary inversion in English –[NPShe] will laugh. –[NPShe] will laugh. – Will [NPshe] laugh? – Will [NPshe] laugh? –[NPThe student who is taking good notesnotes]will –[NPThe student who is taking good notesnotes]will get an A. get an A. – Will [NPthe student who is taking good notesnotes] get an A? 11 12 2 The Null (Ø) Subject Parameter The Null (Ø) Subject Parameter 1.

For example: Thus children acquire properties of language The principle of structure dependency that are not immediately obvious and that are not explicitly taught. A parameter must be set according to the If the child possesses only some general requirements of the language being cognitive ability to make generalizations from acquired. For example: input, many features of the adult language The null subject parameter cannot be acquired. 15 16 17 18 3 CoCo--occurrenceoccurrence of Binding Theory NPs and Pronouns Janeii washed herj. *Janeii washed herii . Binding: The association between a pronoun and an antecedent. Sheii washed Janej. *Sheii washed Janeii . Anaphoric: A term to describe an element (e.g. a Sheii washed herj. *Sheii washed herii . pp)ronoun) that derives its interp retation from some other expression in the discourse. Janeii watched *Sheii watched Antecedent: The expression an anaphoric television before sheii television before Janeii had her dinner. had her dinner. expression derives its interpretation from. Anaphora: The relationship between an anaphoric expression and its antecedent. 19 20 Binding Theory 1. **JohnJohnii saw himii . 2. John saw himself. 3. *Himself saw John. 4. **JohnJohnii saw Johnii . Principle A states that reflexives (and reciprocals , such as "each other") must always be bound in their domains. Principle B states that a pronoun must never be bound within its domain. Principle C states that RR--expressionsexpressions must never be bound. RR--expressionsexpressions are referentialreferential expressions: nonnon-- pronoun, uniquely identifiable entities, such as "the dog", or proper names such as "John". 21 22 The Logical Problem of Language UG and SLA Acquisition If the child comes to the acquisition task solely equipped with abilities to make generalizations from the input Are L1 and L2 acquisition comparable? data, it would seem impossible to arrive at the correct What would constitute evidence for UG in generalizations without a great many errors, if at all.

In addition,,ppg the child appears to get little or no neg ative – A learners’ knowledge of L2 goes beyond evidence because adults react to meaning and sociolinguistic appropriateness not to errors of form. what could be induced from the input. – A learners’ knowledge of L2 goes beyond The UG solution: Knowledge about what is and is not what could be reconstructed from the L1 possible in adult language stems in part from an innate (e.g., resetting parameters). universal grammar, containing principles and parameters which constrain grammars in various ways. – There are no violations of UG in interlanguage (no “wild grammars”). 23 24 4 A Test for the Availability of UG Subjacency in Adult SLA The Principle of Subjacency is a constraint Schachter, J.
