Sociolinguistic Variation in Hong Kong Sign Language

<p>Internal lexical variation appears to be a prominent feature within signed languages; it is perhaps a result of their distinctive acquisition patterns and fragile transmission. Recent research in different signed languages indicates that sociolinguistic variation within signed languages parallels some patterns found in spoken languages, though with some factors distinct to the former. This research examines sociolinguistic variation in a regional sign language, Hong Kong Sign Language (HKSL), “spoken” by deaf people in Hong Kong. The focus of this dissertation is lexical variation and two phonological variations in the signs DEAF/HEARING, and ‘location drop’ in articulation of signs made at the forehead. This research project is a modified replication of the earlier studies in American Sign Language, Australian Sign Language, and New Zealand Sign Language (Lucas, Bayley, & Valli, 2001; Schembri, McKee, McKee, Pivac, Johnston, & Goswell, 2009; McKee & McKee, 2011). The data of 65 participants recruited from the researcher’s networks in the HKSL community using the friend-of-a-friend method was analyzed. Three types of data were collected: free conversation, picture naming and interview. A set of 120 pictures (with/without Chinese characters) was used to elicit signs for the concepts represented. Fifty-one out of these 120 concepts were analyzed from the semantic domains of colour, kinship, number, and country/region. Results show that school attended and age of signer play a prominent role in lexical variation. A gender effect is also found in several concepts. In addition to individual lexical items, the use of compound signs, ‘citation forms’ and handedness in number signs were also examined. Various social factors including school, age, gender, education, and work environment, interact with each other to constrain the variant choices. While numbers over ten can be produced either one-handed or two-handed, signs for hundred and tens highly favour the latter. Regarding phonological variation, conversation videos of 40 participants were annotated for the DEAF/HEARING and location drop variables. For the DEAF/HEARING variables, preliminary investigation of the movement pattern demonstrates that there may be two different types of change going on: linguistically driven (originated from compounds) and socially driven (motivated by redefining deaf identity). It also suggests that DEAF is in a further stage of development than HEARING. For the location variable, twenty tokens from each participant were coded, producing 800 tokens for multivariate analysis. Again, complex correlations between social factors are found to constrain the lowering of signs. The findings further indicate that this change has originated in the deaf school name signs due to their salience, and signers from these schools have led the change. In addition, the results in both phonological variables show that grammatical constraints play an essential role in conditioning variant choices, which parallels results of the previous studies. In sum, the lexical analysis results affirm the crucial role of school in shaping a signer’s lexicon. The findings of the phonological variables confirm the role of grammatical function. Also, there is evidence of language change in progress in this young sign language.</p>

Repetition Preferences in Two-Handed Balanced Signs: Vestigial Locomotor Central Pattern Generators Shape Sign Language Phonetics and Phonology

Language is produced by bodies that evolved to fulfill a variety of functions, most of them non-communicative. Vestigial influences of adaptation for quadrupedal locomotion are still affecting bimanual actions, and have consequences on manual communication systems such as sign languages of the deaf. We discuss how central pattern generators (CPGs), networks of nerve cells in the spinal cord that drive locomotion, influence bimanual actions with alternating movements to be produced with repeated motion. We demonstrate this influence with data from three unrelated sign languages, American Sign Language, British Sign Language, and Hong Kong Sign Language: in all three sign languages two-handed balanced signs produced with alternating movements have a tendency to be repeated, whereas other types of two-handed balanced signs show the opposite tendency for single movements. These tendencies cannot be fully explained by factors such as iconicity. We propose a motoric account for these results: as alternating bimanual movements are influenced by locomotor patterns, they favor repeated movements.

Crosslinguistic similarity and variation in the simultaneous morphology of sign languages

Two differences between signed and spoken languages that have been widely discussed in the literature are: the degree to which morphology is expressed simultaneously (rather than sequentially), and the degree to which iconicity is used, particularly in predicates of motion and location, often referred to as classifier predicates. In this paper we analyze a set of properties marking agency and number in four sign languages for their crosslinguistic similarities and differences regarding simultaneity and iconicity. Data from American Sign Language (ASL), Italian Sign Language (LIS), British Sign Language (BSL), and Hong Kong Sign Language (HKSL) are analyzed. We find that iconic, cognitive, phonological, and morphological factors contribute to the distribution of these properties. We conduct two analyses—one of verbs and one of verb phrases. The analysis of classifier verbs shows that, as expected, all four languages exhibit many common formal and iconic properties in the expression of agency and number. The analysis of classifier verb phrases (VPs)—particularly, multiple-verb predicates—reveals (a) that it is grammatical in all four languages to express agency and number within a single verb, but also (b) that there is crosslinguistic variation in expressing agency and number across the four languages. We argue that this variation is motivated by how each language prioritizes, or ranks, several constraints. The rankings can be captured in Optimality Theory. Some constraints in this account, such as a constraint to be redundant, are found in all information systems and might be considered non-linguistic; however, the variation in constraint ranking in verb phrases reveals the grammatical and arbitrary nature of linguistic systems.
