Numerous authors treat the term ‘biolinguistics’ as synonymous with the generative enterprise. Although undeniably Chomskyan in orientation, biolinguistics should not be equated with generative grammar, as the latter does not often seek to go beyond the level of cognition and establish linking hypotheses with the brain. This article attempts to clarify the nature of biolinguistics, highlighting departures from the research agenda routinely assumed by generative practitioners. [ABSTRACT FROM AUTHOR]

Abstract: This article is about the relationship between Dependency Phonology and Government Phonology in general, and the more specific question how exactly a dependency relation may incarnate. The latter issue is raised by the genuine contribution of Government Phonology to phonological theory, i.e. lateral relations among syllabic constituents. Government and licensing describe a dependency relationship between a head and a dependent, but are non-arboreal. Their application therefore mechanically leads to the elimination of trees (deforestation). Arboreal syllable structure, however, is the spine of Structural Analogy, since it parallels syntactic arboreal structure. The question is thus whether arboreal and lateral descriptions of syllable structure are just notational variants (in which case Structural Analogy with syntactic trees can be maintained), or whether they are really different. It is shown that the latter is the case, and that the different expression of dependency relations in syntax and phonology is due to two things: a design property of syntax, concatenation (which is absent from phonology), and an input condition to phonological computation, linearity (which is absent from syntax). Hierarchical structure is thus implemented in module-specific ways: concatenation in syntax (the minimalist device Merge) produces trees (while invalidating the lateral option). It is therefore argued that the arboreal means of expressing dependency relations is the result of concatenation, and of nothing else: no concatenation, no trees. It thus follows from the fact that phonology does not concatenate anything that there cannot be any tree-building device in this module. An appreciable side-effect of this perspective is an explanation of a long-standing observation, i.e. the absence of recursion in phonology: no trees, no recursion. On the other hand, linearity in phonology produces lateral relations (and makes trees unworkable). A related issue discussed is what kinds of third factor explanation are desirable, given that everybody is after “more general, language-unspecific” motivations for the workings of grammar: Chomskian minimalism/biolinguistics as much as anti-chomskian “Cognitive” Grammar and the work by John Anderson. Candidates are global notions such as cognitive salience on the one hand, or more concrete things such as linearity and concatenation on the other. It appears that the current striving for the former is an attempt at turning back the clocks: the evolution of Cognitive Science since Franz-Joseph Gall’s 19th century phrenology was in the opposite direction.

Abstract: Although variation and heterogeneity are generally recognized as a characteristic of linguistic usage, they are hardly conceived as a fundamental dimension of grammar. Introducing a distinction between an exemplum linguistics and a datum linguistics, we show that the history of the language sciences, both conceptually and descriptively, is organized around opposing conceptions of what a linguistic fact is. While Generative Grammar and its practitioners are clearly examples of the first, corpus linguistics illustrates the second conception. The upsurge of datum linguistics and of usage based models since the beginning of the 21st century allows for a fundamental reassessment of the functional role of variation in language. We show that while the biolinguistic program rests on the negation of the sociocultural framing of the language faculty and denies any functional impact of communicational competence in shaping language and grammars, constructional approaches and usage-based linguistics make room for a Darwinian sociocultural conception. In such a conception, communication is a leading force in the emergence and stabilization of human linguistic competence, both diachronically and synchronically. In this approach, variation and heterogeneity are to be seen as core factors in shaping language. Thus, as argued some 50years ago by Weinreich, variation and heterogeneity are to be regarded as structurally functional, and as fundamental dimensions of language. [Copyright &y& Elsevier]
