Experience with a visual-spatial language may influence certain cognitive processes (Keehner and Gathercole 2007). Spatial ability is an important cognitive skill (Linn and Petersen 1985).

Teachers of deaf children express concern over a lack of curricular materials appropriate for and beneficial to the deaf population, particularly for language and literacy development and in early childhood classrooms.

Explores the acquisition of productive verbs and (spatial) agreement of American Sign Language (ASL) in the signing of two deaf children with hearing parents. The children, observed at two ages, initially showed markedly different developmental trends. Then their grammatical development converged, and they were able to suit ASL to the kind of…
