Relational Network Theory (RNT), also known as Neurocognitive Linguistics (NCL) and formerly as Stratificational Linguistics or Cognitive-Stratificational Linguistics, is a connectionist theoretical framework in linguistics primarily developed by Sydney Lamb which aims to integrate theoretical linguistics with neuroanatomy. It views the linguistic system of individual speakers, responsible for language comprehension and production, as consisting of networks of relationships which interconnect across different "strata" (or "levels") of language. These relational networks are hypothesized to correspond to neural maps of cortical columns or minicolumns in the human brain. [1] Consequently, RNT is related to the wider family of cognitive linguistic theories. [2] Furthermore, as a functionalist approach to linguistics, RNT shares a close relationship with Systemic Functional Linguistics (SFL). [3]
The origins of Relational Network Theory date to 1957, when Sydney Lamb completed his PhD dissertation on the Uto-Aztecan language Mono. Contrary to prevailing structuralist methods at the time, which stipulated discovery procedures assuming two levels of structure (morphology and phonology), Lamb's dissertation argued that Mono was better described with four strata: the morphemic, allomorphic, morphophonemic, and phonemic. The relationships between the strata were postulated to be realizational, so that morphemes were realized by allomorphs, allomorphs realized by morphophonemes, and morphophonemes by phonemes. He later extended this argument to English in 1958 in a presentation to the Berkeley Linguistics Group. [4] At this stage, Lamb regarded the main innovative insight of his new framework to be the multi-stratified structure of language, hence why "Stratificational Grammar" was initially chosen as the framework's name.
The strata concept continued to be developed by Lamb under the influence of Louis Hjelmslev's glossematics, namely as an extension of Hjelmslev's notion of the linguistic sign as having an "expression plane" and a "content plane". [5] In fall 1964, inspired by a passage from Hjelmslev's Prolegomena to a Theory of Language, Lamb developed the insight that realizational relationships between units of different strata constituted a network, and that the units themselves were nothing but points in the network defined solely by realizational relations with other points. [4]
Also in 1964, Lamb encountered Michael Halliday's system network notation from Systemic Functional Linguistics for the first time. Building on the network insight from Hjelmslev, Lamb made three adaptations to Halliday's notation to create relational network notation: (1) a 90 degrees clockwise rotation of the diagrams, (2) the use of a triangle instead of curly brackets to represent conjunctive 'AND' nodes, and (3) the introduction of ordered realization. [6]
The first public presentation of the relational network notation was given a year later in 1965, in a lecture delivered by Lamb at the Linguistic Institute of the University of Michigan. Other linguists in attendance at that lecture included Ronald Langacker, Ruth Brend, and Lamb's students David G. Lockwood and Peter A. Reich. [4] It was also in 1965 that Reich first pointed out to Lamb that his relational networks seemed strikingly similar to neurological networks, [7] though Halliday states that Lamb was already aware of the possibility of relating linguistic theory to actual neural processes as early as 1963. [5]
RNT suggests that the linguistic system may be analyzed according to separate 'strata', or levels. The strata are ordered hierarchically and, whilst there are no clear-cut boundaries between strata, the elements of each stratum share similar characteristics. For example, a lexical item in the lexicogrammatical stratum is typically a specific sequence of phonemes which connects one or more lexical meanings in the semantic stratum. Several strata are involved in the production of a sound from an initial idea. In linguistic production, each stratum provides actualization or realization for the next lower stratum. Thus, speaking a word would involve a realizational pathway from the semantic stratum to the lexicogrammar, then the phonology, and then the phonetics. The reverse direction is true for linguistic perception and comprehension.
Some commonly posited stratificational units and their strata include:
In contrast to generativist approaches to linguistics, Stratificational Linguistics does not support the notion of an autonomous stratum for syntax. Instead, the term 'lexicogrammar', borrowed from Systemic Functional Linguistics, is preferred because Stratificational Linguistics suggests that syntactic categories are merely labels for classifying different types of lexemes but do not actually play any role in the realization of the lexemes. [8] [1] Rather, it is posited that what is traditionally called 'syntax' is simply the result of what orderings or sequences of lexemes are possible in the lexicogrammatical system of an individual person. In other words, there is no need to posit a separate stratum for syntax to account for syntactic phenomena. It has been further suggested that each lexeme has its own syntactic pattern which determines how it combines with other lexemes, a stance shared with Construction Grammar. [8]
Linguistic units in RNT are conceptualised as relational networks. Simply put, a linguistic unit at any stratum is defined in relation to other units. For example, the phonemic sequence /bɔɪ/ may be analyzed as a network node which is activated when the nodes for /b/, /ɔ/ and /ɪ/ are also activated. Similarly, the node for the sequence /thɔɪ/ gets activated when /th/, /ɔ/ and /ɪ/ are also activated. The two sequences /bɔɪ/ and /thɔɪ/ are defined in relation to the set of phoneme nodes /th/, /b/, /ɔ/ and /ɪ/, and their relationships can be graphed as a relational network diagram. [9]
Functional linguistics is an approach to the study of language characterized by taking systematically into account the speaker's and the hearer's side, and the communicative needs of the speaker and of the given language community. Linguistic functionalism spawned in the 1920s to 1930s from Ferdinand de Saussure's systematic structuralist approach to language (1916).
The following outline is provided as an overview and topical guide to linguistics:
In linguistics, morphology is the study of words, including the principles by which they are formed, and how they relate to one another within a language. Most approaches to morphology investigate the structure of words in terms of morphemes, which are the smallest units in a language with some independent meaning. Morphemes include roots that can exist as words by themselves, but also categories such as affixes that can only appear as part of a larger word. For example, in English the root catch and the suffix -ing are both morphemes; catch may appear as its own word, or it may be combined with -ing to form the new word catching. Morphology also analyzes how words behave as parts of speech, and how they may be inflected to express grammatical categories including number, tense, and aspect. Concepts such as productivity are concerned with how speakers create words in specific contexts, which evolves over the history of a language.
Michael Alexander Kirkwood Halliday was a British linguist who developed the internationally influential systemic functional linguistics (SFL) model of language. His grammatical descriptions go by the name of systemic functional grammar. Halliday described language as a semiotic system, "not in the sense of a system of signs, but a systemic resource for meaning". For Halliday, language was a "meaning potential"; by extension, he defined linguistics as the study of "how people exchange meanings by 'languaging'". Halliday described himself as a generalist, meaning that he tried "to look at language from every possible vantage point", and has described his work as "wander[ing] the highways and byways of language". But he said that "to the extent that I favoured any one angle, it was the social: language as the creature and creator of human society".
In linguistics, syntax is the study of how words and morphemes combine to form larger units such as phrases and sentences. Central concerns of syntax include word order, grammatical relations, hierarchical sentence structure (constituency), agreement, the nature of crosslinguistic variation, and the relationship between form and meaning (semantics). There are numerous approaches to syntax that differ in their central assumptions and goals.
Linguistics is the scientific study of human language. Someone who engages in this study is called a linguist. See also the Outline of linguistics, the List of phonetics topics, the List of linguists, and the List of cognitive science topics. Articles related to linguistics include:
In linguistics, X-bar theory is a model of phrase-structure grammar and a theory of syntactic category formation that was first proposed by Noam Chomsky in 1970 reformulating the ideas of Zellig Harris (1951), and further developed by Ray Jackendoff, along the lines of the theory of generative grammar put forth in the 1950s by Chomsky. It attempts to capture the structure of phrasal categories with a single uniform structure called the X-bar schema, basing itself on the assumption that any phrase in natural language is an XP that is headed by a given syntactic category X. It played a significant role in resolving issues that phrase structure rules had, representative of which is the proliferation of grammatical rules, which is against the thesis of generative grammar.
Construction grammar is a family of theories within the field of cognitive linguistics which posit that constructions, or learned pairings of linguistic patterns with meanings, are the fundamental building blocks of human language. Constructions include words, morphemes, fixed expressions and idioms, and abstract grammatical rules such as the passive voice or the ditransitive. Any linguistic pattern is considered to be a construction as long as some aspect of its form or its meaning cannot be predicted from its component parts, or from other constructions that are recognized to exist. In construction grammar, every utterance is understood to be a combination of multiple different constructions, which together specify its precise meaning and form.
Systemic functional linguistics (SFL) is an approach to linguistics, among functional linguistics, that considers language as a social semiotic system.
In linguistics, glossematics is a structuralist theory proposed by Louis Hjelmslev and Hans Jørgen Uldall. It defines the glosseme as the most basic unit of language.
Sydney MacDonald Lamb is an American linguist. He is the Arnold Professor Emeritus of Linguistics and Cognitive Science at Rice University. His scientific contributions have been wide-ranging, including those to historical linguistics, computational linguistics, and the theory of linguistic structure.
Langueandparole is a theoretical linguistic dichotomy distinguished by Ferdinand de Saussure in his Course in General Linguistics.
In linguistics, relational grammar (RG) is a syntactic theory which argues that primitive grammatical relations provide the ideal means to state syntactic rules in universal terms. Relational grammar began as an alternative to transformational grammar.
Structural linguistics, or structuralism, in linguistics, denotes schools or theories in which language is conceived as a self-contained, self-regulating semiotic system whose elements are defined by their relationship to other elements within the system. It is derived from the work of Swiss linguist Ferdinand de Saussure and is part of the overall approach of structuralism. Saussure's Course in General Linguistics, published posthumously in 1916, stressed examining language as a dynamic system of interconnected units. Saussure is also known for introducing several basic dimensions of semiotic analysis that are still important today. Two of these are his key methods of syntagmatic and paradigmatic analysis, which define units syntactically and lexically, respectively, according to their contrast with the other units in the system. Other key features of structuralism are the focus on systematic phenomena, the primacy of an idealized form over actual speech data, the priority of linguistic form over meaning, the marginalization of written language, and the connection of linguistic structure to broader social, behavioral, or cognitive phenomena.
The Copenhagen School is a group of scholars dedicated to the study of linguistics, centered around Louis Hjelmslev (1899–1965) and the Linguistic Circle of Copenhagen, founded by him and Viggo Brøndal (1887–1942). In the mid twentieth century the Copenhagen school was one of the most important centres of linguistic structuralism together with the Geneva School and the Prague School. In the late 20th and early 21st century the Copenhagen school has turned from a purely structural approach to linguistics to a functionalist one, Danish functional linguistics, which nonetheless incorporates many insights from the founders of the Linguistic Circle of Copenhagen.
Linguistics is the scientific study of language. Linguistics is based on a theoretical as well as a descriptive study of language and is also interlinked with the applied fields of language studies and language learning, which entails the study of specific languages. Before the 20th century, linguistics evolved in conjunction with literary study and did not employ scientific methods. Modern-day linguistics is considered a science because it entails a comprehensive, systematic, objective, and precise analysis of all aspects of language – i.e., the cognitive, the social, the cultural, the psychological, the environmental, the biological, the literary, the grammatical, the paleographical, and the structural.
Christian Matthias Ingemar Martin Matthiessen is a Swedish-born linguist and a leading figure in the systemic functional linguistics (SFL) school, having authored or co-authored more than 100 books, refereed journal articles, and papers in refereed conference proceedings, with contributions to three television programs. One of his major works is Lexicogrammatical cartography (1995), a 700-page study of the grammatical systems of English from the perspective of SFL. He has co-authored a number of books with Michael Halliday. Since 2008 he has been a professor in the Department of English at the Hong Kong Polytechnic University. Before this, he was Chair of the Department of Linguistics at Macquarie University in Sydney.
In linguistics, the term formalism is used in a variety of meanings which relate to formal linguistics in different ways. In common usage, it is merely synonymous with a grammatical model or a syntactic model: a method for analyzing sentence structures. Such formalisms include different methodologies of generative grammar which are especially designed to produce grammatically correct strings of words; or the likes of Functional Discourse Grammar which builds on predicate logic.
The idea of language as a linguistic system appears in the linguistic theory of Ferdinand de Saussure, J.R. Firth, Benjamin Lee Whorf, Louis Hjelmslev, and Michael Halliday.
In linguistics, stratification is the idea that language is organized in terms of hierarchically ordered strata. This notion can be traced back to Saussure's dichotomy between signified and signifier and Hjelmslev's expression plane and content plane, but has been explicictly explored as a theoretical concept in stratificational linguistics and systemic functional linguistics.
