Abstract
Purpose: This article examines whether syntactic and vocabulary abilities in American Sign Language (ASL) facilitate 6 categories of language-based analogical reasoning.
Method: Data for this study were collected from 267 deaf participants, aged 7;6 (years;months) to 18;5. The data were collected from an ongoing study initially funded by the U.S. Institute of Education Sciences in 2010. The participants were given assessments of ASL vocabulary and syntax knowledge and a task of language-based analogies presented in ASL. The data were analyzed using mixed-effects linear modeling to first see how language-based analogical reasoning developed in deaf children and then to see how ASL knowledge influenced this developmental trajectory.
Results: Signing deaf children were shown to demonstrate language-based reasoning abilities in ASL consistent with both chronological age and home language environment. Notably, when ASL vocabulary and syntax abilities were statistically taken into account, these were more important in fostering the development of language-based analogical reasoning abilities than were chronological age and home language. We further showed that ASL vocabulary ability and ASL syntactic knowledge made different contributions to different analogical reasoning subconstructs.
Conclusions: ASL is a viable language that supports the development of language-based analogical reasoning abilities in deaf children.
