Home Sign

Home sign (or kitchen sign) is the gestural communication system developed by a deaf child who lacks input from a language model in the family. This is a common experience for deaf children with hearing parents who are isolated from a sign language community.

While not developing into a complete language (as linguists understand the term), home sign systems show some of the same characteristics of sign and oral languages, and are quite distinguishable from the gestures that accompany speech. Words and simple sentences are formed, often in similar patterns despite different home sign systems being developed in isolation from each other. Comparisons are often made between home sign and pidgins. There is great disparity among families with respect to the extent to which family members attempt to learn or participate in the signing of the deaf child. In many cases, no one but the deaf child attempts to sign more than minimally. When two or more children in a family are deaf, however, more sophisticated language develops. (See idioglossia.)

Linguists have been interested in home sign for the insights it offers into the uniquely human ability to generate, acquire, and process language in general, and particularly as it pertains to such topics as the origins of language, notions of linguistic universals, the hypothesized critical period for language acquisition, children's natural tendency to invent language (language acquisition device), and the relationship between gesture and language. The experience of home signers is contrasted with that of feral children who, with no human social interaction, develop no language at all.

Famous quotes containing the words home and/or sign:

    Certainly parents play a crucial role in the lives of individuals who are intellectually gifted or creatively talented. But this role is not one of active instruction, of teaching children skills,... rather, it is support and encouragement parents give children and the intellectual climate that they create in the home which seem to be the critical factors.
    David Elkind (20th century)

    He had that curious love of green, which in individuals is always the sign of a subtle artistic temperament, and in nations is said to denote a laxity, if not a decadence of morals.
    Oscar Wilde (1854–1900)
