ASL Developmental Trends Among Deaf Children, Ages Birth to Five

Sign language delays in deaf 3- to 5-year-olds with hearing parents

Deaf children of hearing parents (DOH) are at risk for early language delays (ELD) due to environmental and etiological factors, compounding the previously reported higher incidence of ELD in deaf children of deaf parents (DOD) compared to the general population. Archival data from the online database of the Visual Communication and Sign Language Checklist yielded 147 ratings of DOH 3- to 5-year-old children whose parents reported American sign language (ASL) being used in the home at least equally to spoken language. Research goals included (1) examining the incidence of ELD in this cohort, (2) investigating differences in outcomes based on the scaling method used, (3) exploring patterns among the ratings of DOH children identified with ELD, (4) comparing the DOH outcomes to published DOD data, and (5) investigating differences between ratings and individual children. The DOH outcomes suggested an incidence of ELD twice that of the previous DOD sample, with a higher percentage of more severe delays. Even DOH children not identified with ELD demonstrated less well-developed ASL skills than their DOD peers. This emphasizes the need for ongoing monitoring of early ASL skills to allow for early identification of needs and adjustment of interventions to address ASL development.

Developing expressive language skills of deaf students through specialized writing instruction

Writing is an essential element of literacy development, and language plays a central role in the composing process, including developing, organizing, and refining ideas. Language and writing are interconnected, making it paramount for educators to attend to the development of deaf students' language skills. In this quasi-experimental study, we examined the impact of strategic and interactive pedagogical approaches, namely Strategic and Interactive Writing Instruction, implemented with deaf students in grades 3-6 to develop genre-specific traits in their expressive language (spoken or signed) and writing. In this study, a total of 16 teachers and their 69 students participated in the treatment and comparison groups. Expressive language and writing samples were collected at the beginning and end of the year for three different genres. Students in the treatment group showed statistically significant gains in their expressive and written language for recount and information genres when compared to students in the comparison group. There was not a significant treatment effect on persuasive expressive language or writing. In addition, there was a significant positive correlation between expressive language and writing at both time points across all three genres. This study provides evidence on the importance of attending to language skills during literacy instruction.

Sign language delays in deaf 3- to 5-year-olds with deaf parents

Research has demonstrated that deaf children of deaf signing parents (DOD) are afforded developmental advantages. This can be misconstrued as indicating that no DOD children exhibit early language delays (ELDs) because of their early access to a visual language. Little research has studied this presumption. In this study, we examine 174 ratings of DOD 3- to 5-year-old children, for whom signing in the home was indicated, using archival data from the online database of the Visual Communication and Sign Language Checklist. Our goals were to (1) examine the incidence of ELDs in a cohort of DOD children; (2) compare alternative scaling strategies for identifying ELD children; (3) explore patterns among behavioral ratings with a view toward developing a greater understanding of the types of language behaviors that may lie at the root of language delays; and (4) suggest recommendations for parents and professionals working with language-delayed DOD children. The results indicated that a significant number of ratings suggested ELDs, with a subset significantly delayed. These children likely require further evaluation. Among the less delayed group, ASL skills, rather than communication or cognition, were seen as the major concern, suggesting that even DOD children may require support developing linguistically accurate ASL. Overall, these findings support the need for early and ongoing evaluation of visual language skills in young DOD children.
