Linguistics and other disciplines Psycholinguistics

The term psycholinguistics was coined in the 1940s and came into more general use after the publication of Charles E. Osgood and Thomas A. Sebeok’s Psycholinguistics: A Survey of Theory and Research Problems (1954), which reported the proceedings of a seminar sponsored in the United States by the Social Science Research Council’s Committee on Linguistics and Psychology.

The boundary between linguistics (in the narrower sense of the term; see the introduction of this article) and psycholinguistics is difficult, perhaps impossible, to draw. So too is the boundary between psycholinguistics and psychology. What characterizes psycholinguistics as it is practiced today as a more or less distinguishable field of research is its concentration upon a certain set of topics connected with language and its bringing to bear upon them the findings and theoretical principles of both linguistics and psychology. The range of topics that would be generally held to fall within the field of psycholinguistics nowadays is rather narrower, however, than that covered in the survey by Osgood and Sebeok.

Language acquisition by children

One of the topics most central to psycholinguistic research is the acquisition of language by children. The term acquisition is preferred to “learning,” because “learning” tends to be used by psychologists in a narrowly technical sense, and many psycholinguists believe that no psychological theory of learning, as currently formulated, is capable of accounting for the process whereby children, in a relatively short time, come to achieve a fluent control of their native language. Starting in the 1960s, research on language acquisition was strongly influenced by Chomsky’s theory of generative grammar, and the main problem to which it addressed itself was how it is possible for young children to infer the grammatical rules underlying the speech they hear and then to use these rules for the construction of utterances that they have never heard before. It was Chomsky’s conviction, shared by a number of psycholinguists, that children are born with a knowledge of the formal principles that determine the grammatical structure of all languages, and that it is this innate knowledge that explains the success and speed of language acquisition. Others have argued that it is not grammatical competence as such that is innate but more general cognitive principles and that the application of these to language utterances in particular situations ultimately yields grammatical competence. Many works have stressed that all children go through the same stages of language development regardless of the language they are acquiring. It has also been asserted that the same basic semantic categories and grammatical functions can be found in the earliest speech of children in a number of different languages operating in quite different cultures in various parts of the world.

Although Chomsky was careful to stress in his earliest writings that generative grammar does not provide a model for the production or reception of language utterances, there has been a good deal of psycholinguistic research directed toward validating the psychological reality of the units and processes postulated by generative grammarians in their descriptions of languages. Experimental work in the early 1960s appeared to show that nonkernel sentences took longer to process than kernel sentences and, even more interestingly, that the processing time increased proportionately with the number of optional transformations involved. Later work cast doubt on these findings, and most psycholinguists are now more cautious about using grammars produced by linguists as models of language processing. Nevertheless, generative grammar remained a valuable source of psycholinguistic experimentation, and the formal properties of language, discovered or more adequately discussed by generative grammarians than they have been by others, were generally recognized to have important implications for the investigation of short-term and long-term memory and perceptual strategies.
