Two studies investigating the use of a sign language system (MAKATON) in children with Down syndrome reported improvements in language development.
One study investigating the use of core vocabulary in children with Down syndrome reported increased spontaneous use of core vocabulary from a variety of syntactic, semantic, and pragmatic functions in both signed or spoken language productions.
Three studies investigating the use of the Picture Exchange Communication System in children with Down syndrome (DS) reported improvements in language and social communication. The studies noted increased interaction between children with DS and their peers.
One study investigating the use of a digital interactive board in children with Down syndrome reported significant benefits in the areas of socialization, independence, and self-esteem.
Four studies investigating the use of speech-generating devices (SGDs) in children with Down syndrome reported improved communication in the domains of speech, cognition, and socializing. One study noted that use of an SGD alone did not promote social interactions.
Two studies investigating the use of Picture Communication Symbols in children with Down syndrome reported increased speed in identifying target vocabulary categories.
