Language experience in LSF development: Behavioral evidence from a sentence repetition task.

ABSTRACT: 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.

Project description:In bi- and monolingual children, nonword repetition tasks (NWRTs) differentiate between typically developing (TD) and children with Developmental Language Disorder (DLD). Language specificity is a crucial factor in nonword construction especially for multilingual children. While language-specific nonwords seem less artificial than non-specific nonwords, the application of language-specific phonemes may be less suitable for bilingual children who are exposed to the target language less than monolingual peers. This study evaluates the concurrent and predictive value of a novel, computerized NWRT implemented in the MuLiMi web-platform and its potential in the discrimination of bilingual children with and without DLD, investigating the role of nonwords’ language specificity. Thirty-seven children (of whom 17 had an objective risk of phonological disorders) with at least one Italian-speaking parent, living and attending kindergartens in Germany were tested with the MuLiMi NWRT and German standardized language tests. Caregivers and kindergarten teachers filled in questionnaires. Fourteen of the children were re-tested after 8–12 months. The results suggest that the new test’s concurrent and discriminative validity are good. Analysis of variance revealed highly significant differences between children with and without (an objective risk of) phonological disorders and a significant interaction between nonword specificity and risk group. Significant correlations of initial scores with follow-up scores collected after 8–12 months were also found, as well as correlations with improvements in language abilities. In conclusion, although both language-specific and language-non-specific nonword repetition can support DLD risk identification in bilingual children, language-specific stimuli appear to be particularly sensitive indicators. This is interpreted as confirming DLD children’s reduced sensitivity to frequent, familiar characteristics of the linguistic stimuli. The test’s discriminative and concurrent validity showed to be robust to various potentially influencing factors like patterns of language exposure.
