Years of Research
Baby Signs Researchers Linda Acredolo and Susan Goodwyn advise that you start molding signs at birth. Their 20 year research studies have proven that signing actually enhances language, cognitive, social and emotional development. They have proven that signing can have long term effects on a child's intelligence and provide a strong foundation for literacy. They believe that babies are more likely to possess the ability to remember signs by the time they are six months old!
Marilyn Daniels, author of Dancing with Words: Signing for hearing Children's Literacy (Bergin & Garvey, 2001), discovered in her research that pre-kindergarten hearing students who had the benefit of adding the visual and kinesthetic (movement) elements of sign language to verbal and written language scored significantly higher on standardized vocabulary tests than hearing students with no sign instruction. Adding sign language to verbal communication has been found to help enhance a preschool child's vocabulary, spelling and early reading skills.
