Deaf individuals’ bilingual abilities: American Sign Language proficiency, reading skills, and family characteristics

The current study investigated the bilingual abilities of 55 Deaf individuals, examining both American Sign Language (ASL) competency and English reading skills. Results revealed a positive relationship between ASL competency and English skills, with highly competent signers scoring higher on a measure of reading comprehension. Additionally, family characteristics (e.g., parental education level, family hearing status) were entered into the analysis to ascertain their effect on Deaf individuals’ bilingual abilities. The findings support the theory that competency in ASL may serve as a bridge to the acquisition of English print. Moreover, the findings provide support for the critical period hypothesis for first language acquisition and its later impact on other cognitive and academic skills

Morphological knowledge and decoding skills of deaf readers

Many studies have reported the necessity of phonological awareness to become a skilled reader, citing barriers to phonological information as the cause for reading difficulties experienced by deaf individuals. In contrast, other research suggests that phonological awareness is not necessary for reading acquisition, citing the importance of higher levels of syntactic and semantic knowledge. To determine if deaf students with higher language skills have better word decoding strategies, students responded to a morphological test, where monomorphemic words and multimorphemic words were matched to their definitions. Two studies are reported, one focusing on English placement levels and a second with formal measures of both ASL and English language proficiency. Results in-dicated that performance on the morphological decoding test was related to language proficiency scores, but not to phonological awareness scores
