Repetition Task

In psycholinguistics and clinical linguistics, the Sentence Repetition Task (SRT) is known to be a valuable tool to screen general language abilities in both spoken and signed languages. This task enables users to reliably and quickly assess linguistic abilities at different levels of linguistic analysis such as phonology, morphology, lexicon, and syntax. To evaluate sign language proficiency in deaf children using French Sign Language (LSF), we designed a new SRT comprising 20 LSF sentences. The task was administered to a cohort of 62 children– 34 native signers (6;09–12 years) and 28 non-native signers (6;08–12;08 years)–in order to study their general linguistic development as a function of age of sign language acquisition (AOA) and chronological age (CA). Previously, a group of 10 adult native signers was also evaluated with this task. As expected, our results showed a significant effect of AOA, indicating that the native signers repeated more signs and were more accurate than non-native signers. A similar pattern of results was found for CA. Furthermore, native signers made fewer phonological errors (i.e., handshape, movement, and location) than non-native signers. Finally, as shown in previous sign language studies, handshape and movement proved to be the most difficult parameters to master regardless of AOA and CA. Taken together, our findings support the assumption that AOA is a crucial factor in the development of phonological skills regardless of language modality (spoken vs. signed). This study thus constitutes a first step toward a theoretical description of the developmental trajectory in LSF, a hitherto understudied language.

The evaluation of sign language proficiency needs to be based on measures with well-established psychometric proprieties. To date, no valid and reliable test is available to assess Polish Sign Language ( Polski Język Migowy, PJM) skills in deaf children. Hence, our aim with this study was to adapt the British Sign Language Receptive Skills Test (the first standardized test to determine sign language proficiency in children) into PJM, a less researched sign language. In this paper, we present the first steps in the adaptation process and highlight linguistic and cultural similarities and differences between the British Sign Language Receptive Skills Test and the PJM adaptation. We collected data from 20 deaf children who were native signers (age range: 6 to 12) and 30 deaf children who were late learners of PJM (age range: 6 to 13). Preliminary analyses showed that the PJM Receptive Skills Test has acceptable psychometric characteristics (item analysis, validity, reliability, and sensitivity to age). Our long-term goal with this work was to include younger children (age range: 3 to 6) and to standardize the PJM Receptive Skills Tests, so that it can be used in educational settings and in scientific research.

In this paper the prosodic structure of American Sign Language (ASL) narratives is analyzed in deaf native signers (L1-D), hearing native signers (L1-H), and highly proficient hearing second language signers (L2-H). The results of this study show that the prosodic patterns used by these groups are associated both with their ASL language experience (L1 or L2) and with their hearing status (deaf or hearing), suggesting that experience using co-speech gesture (i.e. gesturing while speaking) may have some effect on the prosodic cues used by hearing signers, similar to the effects of the prosodic structure of an L1 on an L2.

The Impact

Abstract Sign language research is important for our understanding of languages in general and for the impact it has on policy and on the lives of deaf people. There is a need for a sign language proficiency measure, to use as a grouping or continuous variable, both in psycholinguistics and in other sign language research. This article describes the development of a Swedish Sign Language Sentence Repetition Test (STS-SRT) and the evidence that supports the validity of the test’s interpretation and use. The STS-SRT was administered to 44 deaf adults and children, and was shown to have excellent internal reliability (Cronbach’s alpha of 0.915) and inter-rater reliability (Intraclass Correlation Coefficient [ICC] = 0.900, p < .001). A linear mixed model analysis revealed that adults scored 20.2% higher than children, and delayed sign language acquisition were associated with lower scores. As the sign span of sentences increased, participants relied on their implicit linguistic knowledge to scaffold their sentence repetitions beyond rote memory. The results provide reliability and validity evidence to support the use of STS-SRT in research as a measure of STS proficiency.

Surface Based Morphometry

We investigated, using voxel-based morphometry (VBM), how deafness and sign language experience affect the anatomical structures of the human brain by comparing gray matter (GM) and white matter (WM) structures across congenitally deaf native signers, hearing native signers, and hearing sign-naïve controls (n = 90). We also compared the same groups on cortical thickness, surface area, and local gyrification using surface-based morphometry (SBM). Both VBM and SBM results revealed deafness-related changes in visual cortices and right frontal lobe. The GM in the auditory cortices did not appear to be affected by deafness; however, there was a significant WM reduction in left Heschl's gyrus for deaf signers only. The SBM comparisons revealed changes associated with lifelong signing experience: expansions in the surface area within left anterior temporal and left occipital lobes, and a reduction in cortical thickness in the right occipital lobe for deaf and hearing signers. Structural changes within these brain regions may be related to adaptations in the neural networks involved in processing signed language (i.e., visual perception of face and body movements). Hearing native signers also had unique neuroanatomical changes (e.g., reduced gyrification in premotor areas), perhaps due to lifelong experience with both a spoken and a signed language.

The Rasch Model

Abstract This paper presents the design and development of the Hong Kong Sign Language-Sentence Repetition Test (HKSL-SRT). It will be argued that the test offers evidence of discriminability, reliability, as well as practicality and can serve as an effective global measurement of individuals' proficiency in HKSL. The full version of the test consists of 40 signed sentences of increasing length and complexity. Specifically, we will evaluate the manual and non-manual components of these sentences to find out whether and to what extent they can differentiate three groups of deaf signers, namely, native signers, early learners and late learners. Statistical analyses show that the test scores based on a correct repetition of the manual signs of each sentence bear a significant negative correlation with signers' age of acquisition. Including the correct repetition of non-manuals in the scoring scheme can result in higher reliability and separation index of the test in the Rasch model. This paper will also discuss how psychometric measures of Rasch analysis, including the concept of fit and the rankings of items/persons in the Wright map, have been applied to the original list of the 40 sentence items for the development of a shortened test.

Abstract A renewed interest in understanding the role of iconicity in the structure and processing of signed languages is hampered by the conflation of iconicity and transparency in the definition and operationalization of iconicity as a variable. We hypothesize that iconicity is fundamentally different than transparency since it arises from individuals’ experience with the world and their language, and is subjectively mediated by the signers’ construal of form and meaning. We test this hypothesis by asking American Sign Language (ASL) signers and German Sign Language (DGS) signers to rate iconicity of ASL and DGS signs. Native signers consistently rate signs in their own language as more iconic than foreign language signs. The results demonstrate that the perception of iconicity is intimately related to language-specific experience. Discovering the full ramifications of iconicity for the structure and processing of signed languages requires operationalizing this construct in a manner that is sensitive to language experience.

AbstractThe current study described the development of the MacArthur–Bates Communicative Developmental Inventory (CDI) for Israeli Sign Language (ISL) and investigated the effects of age, sign iconicity, and sign frequency on lexical acquisition of bimodal-bilingual toddlers acquiring ISL. Previous findings bring inconclusive evidence on the role of sign iconicity (the relationship between form and meaning) and sign frequency (how often a word/sign is used in the language) on the acquisition of signs. The ISL-CDI consisted of 563 video clips. Iconicity ratings from 41 sign-naïve Hebrew-speaking adults (Study 1A) and sign frequency ratings from 19 native ISL adult signers (Study 1B) were collected. ISL vocabulary was evaluated in 34 toddlers, native signers (Study 2). Results indicated significant effects of age, strong correlations between parental ISL ratings and ISL size even when age was controlled for, and strong correlations between naturalistic data and ISL-CDI scores, supporting the validity of the ISL-CDI. Moreover, the results revealed effects of iconicity, frequency, and interactions between age and the iconicity and frequency factors, suggesting that both iconicity and frequency are modulated by age. The findings contribute to the field of sign language acquisition and to our understanding of potential factors affecting human language acquisition beyond language modality.

The paper analyzes the results of a sentence repetition task performed by Lithuanian L2 speakers of different language proficiency levels. This paper focuses on a set of targeted verb forms included in the task because they are less likely to occur in free production. The different forms the speakers produced are analyzed by considering their correspondence (or not) to the targeted form, by comparing the speakers among each other with respect to their learner variety and by comparing the task results to the repertoire of the same speaker in the free production data. In multiple cases of failed re-production, the analysis examines what the targeted forms were substituted with and tries to identify possible reasons for such substitution. This analysis confirms the general inability of the basic variety speakers to distinguish between morphologically different forms and the dominant trend showing that L2 learners are more meaning-focused than form-focused. The analysis also shows growing implicit knowledge, or at least gradual passive acquisition, of the less frequent forms as the speaker advances in the post-basic continuum.

The article analyses cross-modal language contact between signed and spoken languages with special reference to the Irish Deaf community. This is exemplified by an examination of the phenomenon of mouthings in Irish Sign Language including its origins, dynamics, forms and functions. Initially, the setup of language contact with respect to Deaf communities and the sociolinguistics of the Irish Deaf community are discussed, and in the main part the article analyses elicited data in the form of personal stories by twelve native signers from the Republic of Ireland. The major aim of the investigation is to determine whether mouthings are yet fully integrated into ISL and if so, whether this integration has ultimately caused language change. Finally, it is asked whether traditional sociolinguistic frameworks of language contact can actually tackle issues of cross-modal language contact occurring between signed and spoken languages.

This study investigates the effects of sentence structure on the number of error sentences and response latency in a sentence-repetition task. Forty female college students repeated short and long test sentences containing either a single self-embedded or right-branching subject-focus or object-focus relative clause. Sentences were also controlled for deletion of the relative pronoun of the relative clause. Sentence structure was found to affect sentence elicited imitation response accuracy and latency in a manner similar to the effects of structure on ease of comprehension. The findings are consistent with a canonical-sentoid strategy explanation of sentence processing during sentence imitation.
