Ray Jackendoff (born January 23, 1945) is an American linguist. He is professor of philosophy, Seth Merrin Chair in the Humanities and, with Daniel Dennett, Co-director of the Center for Cognitive Studies at Tufts University. He has always straddled the boundary between generative linguistics and cognitive linguistics, committed as he is both to the existence of an innate Universal Grammar (an important thesis of generative linguistics) and to giving an account of language that meshes well with the current understanding of the human mind and cognition (the main purpose of cognitive linguistics).
Jackendoff's research deals with the semantics of natural language, its bearing on the formal structure of cognition and its lexical and syntactic expression. He has also done extensive research on the relationship between conscious awareness and the computational theory of mind, on syntactic theory, and, with Fred Lerdahl, on musical cognition, culminating in their Generative theory of tonal music. His theory of conceptual semantics developed into a comprehensive theory on the foundations of language, which indeed is the title of a recent monograph (2002): Foundations of Language. Brain, Meaning, Grammar, Evolution. Much earlier, in his 1983 Semantics and Cognition, he was one of the first linguists to integrate the vision faculty into his account of meaning and human language.
Jackendoff studied under the famed linguists Noam Chomsky and Morris Halle at the Massachusetts Institute of Technology, where he received his PhD in linguistics in 1969. Both Chomsky and Halle are now Institute Professors emeriti at MIT.
Before moving to Tufts in 2005, Jackendoff was professor of linguistics and Chair of the Linguistics Program at Brandeis University from 1971 to 2005. During the 2009 spring semester, he was an external professor at the Santa Fe Institute.
Interfaces and generative grammar
Jackendoff argues against a syntax-centered view of generative grammar (called syntactocentrism by him), at variance with earlier models such as Standard Theory (1968); Extended Standard Theory (1972); Revised Extended Standard Theory (1975); Government and binding theory (1981); Minimalist program (1993), in which syntax is the sole generative component in the language. Jackendoff takes syntax, semantics and phonology all to be generative, connected amongst each other via interface components. Thus, the task of his theory is to formalize the proper interface rules.
While rejecting mainstream generative grammar due to its syntactocentrism, the cognitive semantics school has offered an insight that Jackendoff would sympathize with, namely, that meaning is a separate combinatorial system not entirely dependent upon syntax. Unlike many of the cognitive semantics approaches, he contends that neither syntax alone should determine semantics, nor vice-versa. Syntax need only interface with semantics to the degree necessary to produce properly ordered phonological output (see Jackendoff 1996, 2002; Culicover & Jackendoff 2005).
Contribution to musical cognition
Jackendoff, together with Fred Lerdahl, has been interested in the human capacity for music and its relationship to the human capacity for language. In particular, music has structure as well as grammar (a means by which sounds are combined into structures). When a listener hears music in an idiom he or she is familiar with, the music is not merely heard as a stream of sounds; rather, the listener constructs an unconscious understanding of the music and is able to understand pieces of music never heard previously. Jackendoff is interested in what cognitive structures or "mental representations" this understanding consists of in the listener's mind, how a listener comes to acquire the musical grammar necessary to understand a particular musical idiom, what innate resources in the human mind make this acquisition possible and, finally, what parts of the human music capacity are governed by general cognitive functions and what parts result from specialized functions geared specifically for music (Jackendoff & Lerdahl, 1983; Lerdahl, 2001). Similar questions have also been raised regarding human language, although there are differences. For instance, it is more likely that humans evolved a specialized language module than having evolved one for music, since even the specialized aspects of music comprehension are tied to more general cognitive functions
