Shows that 17 kindergarten children receiving sign language instruction tested significantly higher on the Peabody Picture Vocabulary Test than 17 kindergartners receiving no such instruction. The study's findings confirm that simultaneously presenting words visually, kinesthetically, and orally offers an advantage to young learners. (23…

Reports on an experiment describing the lexical development of a hearing child with a deaf mother and hearing father.
