Linguistic Performanceâ€Definition and Examples

Linguistic performance is the ability to produce and comprehend sentences in a language. Since the publication of Noam Chomskys Aspects of the Theory of Syntax in 1965, most linguists have made a distinction between linguistic competence, a speakers tacit knowledge of the structure of a language, and linguistic performance, which is what a speaker actually does with this knowledge.

The nature and characteristics of a particular instance of linguistic performance and its product(s) are, in reality, determined by a combination of factors: (6) Some of the factors which influence linguistic performance are:(a) the linguistic competence or unconscious linguistic knowledge of the speaker-hearer,(b) the nature and limitations of the speaker-hearers  speech  production and speech perception mechanisms,(c) the nature and limitations of the speaker-hearers memory, concentration, attention and other mental capacities,(d) the social environment and status of the speaker-hearer,(e) the  dialectal  environment of the speaker-hearer,(f) the  idiolect  and individual style of speaking of the speaker-hearer,(g) the speaker-hearers factual knowledge and view of the world in which he lives,(h) the speaker-hearers state of health, his emotional state, and other similar incidental circumstances. Each of the factors mentioned in (6) is a variable in linguistic performance and, as such, may influence the nature and characteristics of a particular instance of linguistic performance and its product(s).Rudolf P. Botha, The Conduct of Linguistic Inquiry: A Systematic Introduction to the Methodology of Generative Grammar. Mouton, 1981 Chomsky on Linguistic Competence and Linguistic Performance In [Noam] Chomskys theory, our linguistic competence is our unconscious knowledge of languages and is similar in some ways to [Ferdinand de] Saussures concept of langue, the organizing principles of a language. What we actually produce as utterances are similar to Saussures parole, and is called linguistic performance.Kristin Denham and Anne Lobeck, Linguistics for Everyone. Wadsworth, 2010Chomsky divides linguistic theory into two parts: linguistic competence and linguistic performance. The former concerns the tacit knowledge of grammar, the latter the realization of this knowledge in actual performance. Chomsky distinctly relegates linguistic performance to the peripherals of linguistic inquiry. Linguistic performance as the actual use of language in concrete situations is viewed as fairly degenerate in quality (Chomsky 1965, 31) because performance is full of errors. . . . Chomskys linguistic competence corresponds to la langue, and Chomskys linguistic performance corresponds to l a parole. Chomskys linguistic competence, however, because it is concerned primarily with the underlying competence, is viewed as superior to de Saussures la langue.Marysia Johnson, A Philosophy of Second Language Acquisition. Yale University Press, 2004Competence concerns our abstract knowledge of our language. It is about the judgments we would make about language if we had sufficient time and memory capacity. In practice, of course, our actual linguistic performance—the sentences that we actually produce--is limited by these factors. Furthermore, the sentences we actually produce often use the more simple grammatical constructions. Our speech is full of false starts, hesitations, speech errors, and corrections. The actual ways in which we produce and understand sentences are also in the domain of performance.In his more recent work, Chomsky (1986) distinguished between externalized language (E-language) and internalized language (I-language). For Chomsky, E-language lingui stics is about collecting samples of language and understanding their properties; in particular, it is about describing the regularities of a language in the form of a grammar. I-language linguistics is about what speakers know about their language. For Chomsky, the primary aim of modern linguistics should be to specify I-language: it is to produce a grammar that describes our knowledge of the language, not the sentences we actually produce.Trevor A.
