“…Siegel and Ryan (1988), for example, found that children with learning disabilities performed significantly more poorly than typically developing children on grammatical error correction tasks. The current results add to the growing literature of identifying language difficulties in children using signed language: BSL (Herman, Rowley, Mason, & Morgan, 2014;Marshall et al, 2014;Mason et al, 2010;Morgan, Herman, & Woll, 2007;Woll & Morgan, 2012) and ASL Quinto-Pozos et al, 2013, Quinto-Pozos, Forber-Pratt, & Singleton, 2011. These findings suggest that reliable assessment tools may need to be developed for specific language backgrounds, such that nonnative signers' scores should be compared to nonnative norms and native signers' scores should be compared to native norms (Herman, Holmes, & Woll, 2001;Mann & Marshall, 2012).…”

Factors influencing native and nonnative signers’ syntactic judgment ability in American Sign Language (ASL) were explored for 421 deaf students aged 7;6–18;5. Predictors for syntactic knowledge were chronological age, age of entering a school for the deaf, gender, and additional learning disabilities. Mixed‐effects linear modeling analysis revealed main effects of each predictor and an interaction between signing status and learning disability. The native signers showed typical syntactic development that varied by chronological age, gender, additional learning disabilities, and age of entering a deaf school. In contrast, the syntactic development of nonnative signers was more variable. It was less tightly related to chronological age and more strongly influenced by the age at which they had entered the school where assessment occurred, which was highly related to length of exposure to a sign language.

“…Morgan, Herman and Woll (2007) reported the case of a deaf five year-old boy with SLI in British Sign Language (BSL). He had no difficulty in understanding single signs and short sentences, but he scored at a three-year-old level on standardized BSL grammar assessments.…”

This is the accepted version of the paper.This version of the publication may differ from the final published version. Permanent repository link AbstractChildren with specific language impairment (SLI) perform poorly on sentence repetition tasks across different spoken languages. Up to this point, sentence repetition has not been investigated in children who have SLI in a signed language. Users of a natural sign language encode different sentence meanings through their choice of signs and by altering the sequence and inflections of these signs. The visual modality influences how grammatical morphology and syntax are instantiated. The grammatical changes are through movement and configuration changes of the hands and face. How would language impairment impact on the acquisition of these types of linguistic devices in child signers? We investigated sentence repetition skills in a group of eleven deaf children who display SLI in British Sign Language (BSL) and eleven deaf controls with no language impairment who were matched for age and years of BSL exposure. The SLI group was significantly less accurate on an overall accuracy score, and they repeated lexical items, overall sentence meaning, sign order, facial expressions and verb morphological structures significantly less accurately than controls. This pattern of language deficits is consistent with the characterization of SLI in spoken languages even though expression is in a different modality. We conclude that explanations of SLI, and of poor sentence repetition by children with this disorder, must be able to account for both the spoken and signed modalities.3

“…Sign language researchers have begun to explore the presence of specific sign language disorders in deaf children (Mason et al, 2010;Morgan et al, 2007;Quinto-Pozos et al, 2011). These initial efforts make use of survey and case study approaches to examine a small number of deaf children, who despite having deaf signing parents, have been identified by teachers as having atypical problems in signing.…”

“…In one example, Morgan et al (2007) reported the case of Paul, a 5-year-old native deaf signer of BSL with a sign language impairment which they entertain as a possible analogue of specific language impairment (SLI) evidenced in a sign language. SLI is diagnosed where a deficit in normal spoken language acquisition is found with no apparent cognitive, social, or neurological cause (Leonard, 1998).…”
