X-within-X Structures and the Nature of Categories

This paper discusses the existence of X-within-X structures in language. Constraints to same-category embedding have been the focus in a number of recent studies. These studies follow a long-standing tradition in linguistic theory that assumes a ban on the adjacency of same-category elements. In the present work, data drawn from a typologically broad variety of languages suggest that the postulated constraints are not so robust. It is shown that X-within-X structures do exist in language. In this context, an argument is made in favor of an unrestricted conceptualization of Merge, independent from category distributions, while recursion is taken to be a property of procedures and not of structures. The discussion of X-within-X patterns provides insights with respect to the attested category distributions, the nature of categories, and the language faculty, from a biologically plausible point of view

From Comparative Languistics to Comparative (Bio)linguistics: Reflections on Variation

What’s in (a) Label? Neural Origins and Behavioral Manifestations of Identity Avoidance in Language and Cognition

The present work defends the idea that grammatical categories are not in- trinsic to mergeable items, taking as a departure point Lenneberg’s (1967, 1975) claim that syntactic objects are definable only contextually. It is ar- gued that there are four different strands of inquiry that are of interest when one seeks to build an evolutionarily plausible theory of labels and operation Label: (i) linguistic constraints on adjacent elements of the same type such as Repetition/Identity Avoidance ([*XX]), (ii) data that flout these constraints ([XX]), (iii) disorders that raise questions as to whether the locus of impairment is a categorial feature per se, and (iv) operation Label as a candidate for human uniqueness. After discussing categorial identity through these perspectives, this work first traces the origins and manifesta-tions of Identity Avoidance in language and other domains of human cog-nition, with emphasis on attention orienting. Second, it pro- poses a new processing principle, the Novel Information Bias, that (i) cap- tures linguistic Identity Avoidance based on how the brain decodes types and tokens and (ii) explains the universal fact that generally the existence of adjacent occur-rences of syntactically and/or phonologically identical tokens is severely constrained

Entangled Parametric Hierarchies: Problems for an Overspecified Universal Grammar

This study addresses the feasibility of the classical notion of parameter in linguistic theory from the perspective of parametric hierarchies. A novel program-based analysis is implemented in order to show certain empirical problems related to these hierarchies. The program was developed on the basis of an enriched data base spanning 23 contemporary and 5 ancient languages. The empirical issues uncovered cast doubt on classical parametric models of language acquisition as well as on the conceptualization of an overspecified Universal Grammar that has parameters among its primitives. Pinpointing these issues leads to the proposal that (i) the (bio)logical problem of language acquisition does not amount to a process of triggering innately pre-wired values of parameters and (ii) it paves the way for viewing language, epigenetic ('parametric') variation as an externalization-related epiphenomenon, whose learning component may be more important than what sometimes is assumed

On trade-offs in bilingualism and moving beyond the stacking the deck fallacy

Despite a meteoric rise, results in the cognitive science of bilingualism present with significant inconsistency. In parallel, there is a striking absence of an ecologically valid theory within bilingualism research. How should one interpret the totality of available data that can pull in opposing directions? To proceed, we need to identify which practices impede progression. Hitherto, we bring to the fore an undiscussed practice, contextualizing how it impacts the ability to embed the available results into an overarching theory. We suggest that a STACKING THE DECK FALLACY – the tendency to engage differently with available evidence, directing focus to specific sub-samples – hampers theory formation. We put forth a proposal for making progress, building on the premise that what is lacking in the field is a unifying perspective that reconciles seemingly contradictory results. We suggest that the necessary shift of perspective towards progress crucially entails linking the notions of SPECTRUM and TRADE-OFF

Language and complexity considerations: A biolinguistic perspective

The notion of complexity recurrently shows up in the context of language studies. From a Chomskyan/biolinguistic perspective, and given the uniform character of language acquisition, it has been assumed that all languages are equally complex or simple. However, the proper focus of Chomskyan linguistics is not natural languages, but the language faculty. Here, we discuss complexity in this domain, relying on Deacon's (2006) distinction between various levels of complexity. The discussion focuses on grammars of I(nternal)-languages and how these display traces of cumulative complexity (Deacon's third level) that go beyond the narrow confines of internalism. Focusing on instances of recent (sign) language emergence, and evidence from birdsongs, we argue that biolinguistics would be wrong to ignore what it can learn from how socio-cultural factors affect the linguistic phenotype

A demonstration of the uncomputability of parametric models of language acquisition and a biologically plausible alternative

The logical problem of language acquisition has been at the forefront of psycholinguistics and behavioral neuroscience for decades. One of the most influential answers to the problem of how successful acquisition occurs on the basis of noisy input suggests that the child is aided by innate principles and parameters (P&P). These are conceived aspart of our biological endowment for language. Previous work on the computability of parametric models has focused on the process of parameter-setting,leaving settability unaddressed. Settability is a key notion in parametric models since it provides an answer to the logical problem of language acquisition: the setting of one parameter carries implications for the settability of others, minimizing the child’s task. However, a mathematical analysis of the expected probability of successful computation of settability relations has not been carried out. We report results from a novel program developed to calculate the probability of successful computation of a network of 62 linguistic parameters as attested in 28 languages, spanning across 5 language families. The results reveal that some parameters have an extremely low probability of successful computation, such that trillions of unsuccessful computations are expected before a successful setting occurs. Using the same program, we performed an additional second analysis to a different network, covering 94 parameters from58 languages and 15 language families. In this case, the estimated number of expected unsuccessful computations rose from trillions to quadrillions. These results raise concerns about the computational feasibility of the highly influential P&P approach to language development. Merging insights from various acquisition models, including some developed within P&P, a biologically plausible alternative is offered for the process of deciphering a target grammar in the acquisition of both spoken and signed languages. Overall, our analysis of the P&P approach to language acquisition centers learnability and computability constraints as the major factors for determining the psychological plausibility of grammar development
