Signed Languages: A Triangular Semiotic Dimension

Since the beginning of signed language research, the linguistic units have been divided into conventional, standard and fixed signs, all of which were considered as the core of the language, and iconic and productive signs, put at the edge of language. In the present paper, we will review different models proposed by signed language researchers over the years to describe the signed lexicon, showing how to overcome the hierarchical division between standard and productive lexicon. Drawing from the semiotic insights of Peirce we proposed to look at signs as a triadic construction built on symbolic, iconic, and indexical features. In our model, the different iconic, symbolic, and indexical features of signs are seen as the three sides of the same triangle, detectable in the single linguistic sign (Capirci, 2018; Puupponen, 2019). The key aspect is that the dominance of the feature will determine the different use of the linguistic unit, as we will show with examples from different discourse types (narratives, conference talks, poems, a theater monolog).

Discussion of Issues Related to Language Assessment Literacy in Second Signed and Spoken Languages

This chapter is a joint discussion of key items related to language assessment literacy related to signed and spoken language assessment that were discussed in Chapters 11.1 and 11.2, and the implications that these issues might have on the other field. It is clear that language assessment literacy (LAL) in the context of signed languages—(S)LAL by the authors—is still in a very nascent form. Although in the field of spoken language assessment there is a tendency to discuss LAL as being a “new” development and recent scholarship suggests that issues and constructs remain undertheorized, there is a considerable body of literature on LAL oriented toward spoken language (as surveyed in the Chapter 11.1), to the extent that LAL is now a core area of research and scholarship in the field. This is in sharp contrast with the paucity addressing LAL in the context of signed languages. This chapter is the result of a collaborative process during which the two sets of authors read each other’s chapters and responded to a set of guided questions. The result is the synthesis of this dialogic process.

Discussion of Issues Related to Assessment Constructs in Spoken and Signed Languages

Thinking about what is assessed—the construct—in any language assessment raises questions about the nature of language use, the nature of developmental trajectories, and whose language patterns determine what is ‘standard’. The assessment of signed languages draws attention to assessment practices and understandings that are entrenched, for better or worse, in the assessment of spoken languages. Spoken language assessments of standardized varieties tend to value the written sentence as an ideal unit, a legacy of standardization. Signed language assessments, on the other hand, may be emerging alongside processes of standardization. Capturing semiotic complexity in the construct remains a significant challenge for both signed and spoken language assessments, despite the development of corpora which exemplify it. This chapter discusses these theoretical, ideological, and practical challenges for assessing signed and spoken language abilities. It brings together key ideas from chapters Chapters 7.1 and 7.2 and offers future directions in the development of theory and practice in signed and spoken language assessments.

Discussion of Issues Related to Discourse Analysis in Signed and Spoken Language Assessments

The analysis of discourse in language proficiency interviews reveals many similarities and some issues that are specific to the modality and social context of spoken and signed languages. In this chapter, we comment on points of intersection and difference in the preceding two chapters to highlight how the exchange of insights from signed and spoken language research in this area can stimulate further inquiry and advance theory across both fields. This chapter is a joint discussion of key items related to discourse analysis related to signed and spoken language assessment that were discussed in Chapters 10.1 and 10.2.

Discussion of Issues Related to Assessing the Signed and Spoken Language Skills of Bi/Multilingual Children

This chapter is a joint discussion of key items related to the assessment of bi-/multilingual deaf and hearing learners with and without a developmental language disorder that were presented in Chapters 6.1 and 6.2. While there is a growing body of evidence describing best practice in the assessment of bilingual children who use spoken languages, there is scant evidence or recommendations available regarding the assessment of bilingual children who use signed languages. This discussion outlines how knowledge from the assessment of spoken languages can be used to inform practice in assessing signed languages for bilingual deaf and hard-of-hearing (D/HH) children.

Perceiving fingerspelling via point-light displays: The stimulus and the perceiver both matter

Signed language users communicate in a wide array of sub-optimal environments, such as in dim lighting or from a distance. While fingerspelling is a common and essential part of signed languages, the perception of fingerspelling in varying visual environments is not well understood. Signed languages such as American Sign Language (ASL) rely on visuospatial information that combines hand and bodily movements, facial expressions, and fingerspelling. Linguistic information in ASL is conveyed with movement and spatial patterning, which lends itself well to using dynamic Point Light Display (PLD) stimuli to represent sign language movements. We created PLD videos of fingerspelled location names. The location names were either Real (e.g., KUWAIT) or Pseudo-names (e.g., CLARTAND), and the PLDs showed either a High or a Low number of markers. In an online study, Deaf and Hearing ASL users (total N = 283) watched 27 PLD stimulus videos that varied by Realness and Number of Markers. We calculated accuracy and confidence scores in response to each video. We predicted that when signers see ASL fingerspelled letter strings in a suboptimal visual environment, language experience in ASL will be positively correlated with accuracy and self-rated confidence scores. We also predicted that Real location names would be understood better than Pseudo names. Our findings show that participants were more accurate and confident in response to Real place names than Pseudo names and for stimuli with High rather than Low markers. We also discovered a significant interaction between Age and Realness, which shows that as people age, they can better use outside world knowledge to inform their fingerspelling success. Finally, we examined the accuracy and confidence in fingerspelling perception in sub-groups of people who had learned ASL before the age of four. Studying the relationship between language experience with PLD fingerspelling perception allows us to explore how hearing status, ASL fluency levels, and age of language acquisition affect the core abilities of understanding fingerspelling.

What the frequency list can teach us about Turkish sign language?

Recent studies on linguistics, cognitive science and psychology have shown that describing lexical frequency characteristics can answer many critical questions on language acquisition, mental lexicon and language use. Given the importance of corpus-based methodology, this study reports the preliminary findings from the objective lexical frequency list in TİD based on 103.087 sign tokens. This paper shows that frequency occurrence has a very decisive role on the linguistics categories and language in use. With respect to the multi-functionality of pointing in signed languages, the top ranked ID-gloss occurrences are mostly shaped by the pronominal references. Moreover, when compared to previous studies in terms of lexical density and lexical diversity, TİD shares both similar and different statistical features observed in other signed languages.

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>
