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.

Schizophrenia and cortical blindness: protective effects and implications for language

The repeatedly noted absence of case-reports of individuals with schizophrenia and congenital/early developed blindness has led several authors to argue that the latter can confer protective effects against the former. In this work, we present a number of relevant case-reports from different syndromes that show comorbidity of congenital and early blindness with schizophrenia. On the basis of these reports, we argue that a distinction between different types of blindness in terms of the origin of the visual deficit, cortical or peripheral, is crucial for understanding the observed patterns of comorbidity. We discuss the genetic underpinnings and the brain structures involved in schizophrenia and blindness, with insights from language processing, laying emphasis on the three structures that particularly stand out: the occipital cortex, the lateral geniculate nucleus (LGN), and the pulvinar. Last, we build on previous literature on the nature of the protective effects in order to offer novel insights into the nature of the protection mechanism from the perspective of the brain structures involved in each type of blindness.

(Meta)linguistic abilities of bilectal educators: the case of Cyprus

ABSTRACT The present study examines whether bilectal Greek Cypriot educators are able to identify dialectal (Cypriot Greek) elements superimposed on the standard language (Standard Modern Greek) in a written variety-judgment task. By doing so, (meta)linguistic skills of bilectal teachers from Cyprus were put to the test and later compared to the results of monolingual native Standard Modern Greek-speaking teachers from Greece on the same task. The findings revealed important differences between the performance and the linguistic profiles of the two groups across all levels of linguistic analysis, pointing out to a sharp discrepancy between what counts as ‘standard’ in Cyprus and what the performance in the standard variety really corresponds to. The implications of these findings for classroom language instruction in bilectal contexts are discussed.
