The Development of Argument Structure in Central Taurus Sign Language

Sign Language Studies, 2018

One of the fundamental issues for a language is its capacity to express argument structure unambiguously. This study presents evidence for the emergence and the incremental development of these basic mechanisms in a newly developing language, Central Taurus Sign Language. Our analyses identify universal patterns in both the emergence and development of these mechanisms and in languagespecific trajectories. * Note that there are family members joining the family through marriage and not all of the deaf members of the family live in village 1.

Structural cues for symmetry, asymmetry and non-symmetry in central Taurus sign language

Proceedings of the 12th International Conference on the Evolution of Language (Evolang12)

Central Taurus Sign Language (CTSL) is a village sign language used in three villages in an isolated area in south-central Turkey. This language emerged in the absence of a linguistic model within the last half-century as a result of recessive deafness in these communities, which have deaf populations of 4.8%, .6% and .5%. CTSL provides us with a novel vantage point into how a brandnew system emerges and develops because it is relatively young, still evolving, and the very first creators of this system are still alive today. Previous research has shown that symmetrical and reciprocal predicates have specific and distinct syntactic properties in spoken languages (

The noun-verb distinction in established and emergent sign systems

Language

In a number of signed languages, the distinction between nouns and verbs is evident in the morphophonology of the signs themselves. Here we use a novel elicitation paradigm to investigate the systematicity, emergence, and development of the noun-verb distinction (qua objects vs. actions) in an established sign language, American Sign Language (ASL), an emerging sign language, Nicaraguan Sign Language (NSL), and in the precursor to NSL, Nicaraguan homesigns. We show that a distinction between nouns and verbs is marked (by utterance position and movement size) and thus present in all groups-even homesigners, who have invented their systems without a conventional language model. However, there is also evidence of emerging crosslinguistic variation in whether a base hand is used to mark the noun-verb contrast. Finally, variation in how movement repetition and base hand are used across Nicaraguan groups offers insight into the pressures that influence the development of a linguistic system. Specifically, early signers of NSL use movement repetition and base hand in ways similar to homesigners but different from signers who entered the NSL community more recently, suggesting that intergenerational transmission to new learners (not just sharing a language with a community) plays a key role in the development of these devices. These results bear not only on the importance of the noun-verb distinction in human communication, but also on how this distinction emerges and develops in a new (sign) language.*

One grammar or two? Sign Languages and the Nature of Human Language

Linguistic research has identified abstract properties that seem to be shared by all languages-such properties may be considered defining characteristics. In recent decades, the recognition that human language is found not only in the spoken modality but also in the form of sign languages has led to a reconsideration of some of these potential linguistic universals. In large part, the linguistic analysis of sign languages has led to the conclusion that universal characteristics of language can be stated at an abstract enough level to include languages in both spoken and signed modalities. For example, languages in both modalities display hierarchical structure at sub-lexical and phrasal level, and recursive rule application. However, this does not mean that modality-based differences between signed and spoken languages are trivial. In this article, we consider several candidate domains for modality effects, in light of the overarching question: are signed and spoken languages subject to the same abstract grammatical constraints, or is a substantially different conception of grammar needed for the sign language case? We look at differences between language types based on the use of space, iconicity, and the possibility for simultaneity in linguistic expression. The inclusion of sign languages does support some broadening of the conception of human language-in ways that are applicable for spoken languages as well. Still, the overall conclusion is that one grammar applies for human language, no matter the modality of expression.

The paradox of sign language morphology

Language, 2005

Sign languages have two strikingly different kinds of morphological structure: sequential and simultaneous. The simultaneous morphology of two unrelated sign languages, American and Israeli Sign Language, is very similar and is largely inflectional, while what little sequential morphology we have found differs significantly and is derivational. We show that at least two pervasive types of inflectional morphology, verb agreement and classifier constructions, are iconically grounded in spatiotemporal cognition, while the sequential patterns can be traced to normal historical development. We attribute the paucity of sequential morphology in sign languages to their youth. This research both brings sign languages much closer to spoken languages in their morphological structure and shows how the medium of communication contributes to the structure of languages.* Si l'on pouvait inventer une langue dont les dictions eussent leur signification naturelle, de sorte que tous les hommes entendissent la pensée des autres à la seule prononciation sans en avoir appris la signification, comme ils entendent que l'on se rejoueit lorsque l'on rit, et que l'on est triste quand on pleure, cette langue serait la meilleure de toutes les possibles; car elle ferait la mesme impression sur tous les auditeurs, que feraient les pensées de l'esprit si elles se pouvaient immédiatement communiquer entre les hommes comme entre les Anges. (Mersenne, Harmonie universelle, 1636) [If one could invent a language whose expressions had their natural signification, so that all men could understand the thought of others by pronunciation alone without having learned its signification, as they understand that one is happy when one laughs, and that one is sad when one cries, this language would be the best of all possible: for it would make the same impression on all hearers as would the thoughts of the spirit if they could be communicated immediately between men as between the angels.] [our translation] If humans could communicate by telepathy, there would be no need for a phonological component, at least for the purposes of communication; and the same extends to the use of language generally. (Noam Chomsky, The minimalist program, 1995:221)

On the linguistic status of 'agreement' in sign languages

2011

In signed languages, the arguments of verbs can be marked by a system of verbal modification that has been termed "agreement" (more neutrally, "directionality"). Fundamental issues regarding directionality remain unresolved and the phenomenon has characteristics that call into question its analysis as agreement. We conclude that directionality marks person in American Sign Language, and the ways person marking interacts with syntactic phenomena are largely analogous to morpho-syntactic properties of familiar agreement systems. Overall, signed languages provide a crucial test for how gestural and linguistic mechanisms can jointly contribute to the satisfaction of fundamental a spects of linguistic structure.

Order of the major constituents in sign languages: implications for all language

Frontiers in Psychology, 2014

A survey of reports of sign order from 42 sign languages leads to a handful of generalizations. Two accounts emerge, one amodal and the other modal. We argue that universal pressures are at work with respect to some generalizations, but that pressure from the visual modality is at work with respect to others. Together, these pressures conspire to make all sign languages order their major constituents SOV or SVO. This study leads us to the conclusion that the order of S with regard to verb phrase (VP) may be driven by sensorimotor system concerns that feed universal grammar.
