Gesture - Volume 13, Issue 3, 2013

Many sign languages have semantically related noun-verb pairs, such as ‘hairbrush/brush-hair’, which are similar in form due to iconicity. Researchers studying this phenomenon in sign languages have found that the two are distinguished by subtle differences, for example, in type of movement. Here we investigate two young sign languages, Israeli Sign Language (ISL) and Al-Sayyid Bedouin Sign Language (ABSL), to determine whether they have developed a reliable distinction in the formation of noun-verb pairs, despite their youth, and, if so, how. These two young language communities differ from each other in terms of heterogeneity within the community, contact with other languages, and size of population. Using methodology we developed for cross-linguistic comparison, we identify reliable formational distinctions between nouns and related verbs in ISL, but not in ABSL, although early tendencies can be discerned. Our results show that a formal distinction in noun-verb pairs in sign languages is not necessarily present from the beginning, but may develop gradually instead. Taken together with comparative analyses of other linguistic phenomena, the results lend support to the hypothesis that certain social factors such as population size, domains of use, and heterogeneity/homogeneity of the community play a role in the emergence of grammar.

Iconicity is an acknowledged property of both gesture and sign language. In contrast to the familiar definition of iconicity as a correspondence between individual forms and their referents, we explore iconicity as a shared property among groups of signs, in what we call patterned iconicity. In this paper, we focus on iconic strategies used by hearing silent gesturers and by signers of three unrelated sign languages in an elicitation task featuring pictures of hand-held manufactured tools. As in previous gesture literature, we find that silent gesturers largely prefer a handling strategy, though some use an instrument strategy, in which the handshape represents the shape of the tool. There are additional differences in use of handling and instrument strategies for hand-held tools across the different sign languages, suggesting typological differences in iconic patterning. Iconic patterning in each of the three sign languages demonstrates how gestural iconic resources are organized in the grammars of sign languages.

A first generation family homesign system, dubbed “Z”, from the Tzotzil-speaking township of Zinacantán, in Chiapas, Mexico, provides insight into how a new sign language can begin to distinguish formally different “part-of-speech” categories. After describing the small signing community, consisting of 3 deaf sibling and their intermediate hearing sister, plus a younger cousin — the entire set of fluent adult signers — plus the hearing child of the oldest deaf signer, and setting out some of the theoretical issues surrounding the nature of “part-of-speech” in sign languages, the paper considers three sorts of mechanisms the language has developed to help distinguish signs that refer to objects from signs that refer to actions. These include a set of size-shape specifiers that co-occur with presumed nominal signs, an iconic contrast between different sign formational elements that somewhat inconsistently signal a noun/verb distinction, and, perhaps most interestingly, a construction involving a clearly grammaticalized locative or copular element that allows Z signers to make clear that they are referring to (physical) objects rather than actions. The paper concludes by considering the overall effect of these quite different formal strategies on the evolving language structure.

All established languages, spoken or signed, make a distinction between nouns and verbs. Even a young sign language emerging within a family of deaf individuals has been found to mark the noun-verb distinction, and to use handshape type to do so. Here we ask whether handshape type is used to mark the noun-verb distinction in a gesture system invented by a deaf child who does not have access to a usable model of either spoken or signed language. The child produces homesigns that have linguistic structure, but receives from his hearing parents co-speech gestures that are structured differently from his own gestures. Thus, unlike users of established and emerging languages, the homesigner is a producer of his system but does not receive it from others. Nevertheless, we found that the child used handshape type to mark the distinction between nouns and verbs at the early stages of development. The noun-verb distinction is thus so fundamental to language that it can arise in a homesign system not shared with others. We also found that the child abandoned handshape type as a device for distinguishing nouns from verbs at just the moment when he developed a combinatorial system of handshape and motion components that marked the distinction. The way the noun-verb distinction is marked thus depends on the full array of linguistic devices available within the system.

This paper examines naturally occurring gestures produced in descriptions of numbers and quantities in television newscasts. The results of our analysis show that gestures reveal the metaphorical and spatial nature of numerical thinking. That is, speakers’ hands mimic known spatial mappings between space and quantity, including horizontal mappings (smaller quantities left, larger quantities right), vertical mappings (smaller quantities down, larger quantities up) and size-based mappings (smaller quantities “small”, larger quantities “large”). Speakers frequently switch between these different spatial mappings, and they sometimes combine them within the same gesture. This points to the flexibility of how metaphors can become expressed in gesture, and how domains such as number and quantity can be conceptualized through multiple compatible source domains.
