Communication

Deafblind people communicate in many different ways determined by the nature of their condition, the age of onset, and what resources are available to them. For example, someone who grew up deaf and experienced vision loss later in life is likely to use a sign language
Sign language
A sign language is a language which, instead of acoustically conveyed sound patterns, uses visually transmitted sign patterns to convey meaning—simultaneously combining hand shapes, orientation and movement of the hands, arms or body, and facial expressions to fluidly express a speaker's...

 (in a visually modified or tactual form). Others who grew up blind and later became deaf are more likely to use a tactile mode of their spoken/written language. Methods of communication include:
  • Use of residual hearing (speaking clearly, hearing aid

Identity

It is often assumed deafblind individuals accept both identities. As with most individuals who identify with more than one group on the basis of a single characteristic, a deafblind individual’s identity is similarly complex. Helen Keller

, a prominent activist recognized for her important contributions to the blind population, serves as the perfect example of the complexities of a deafblind individual’s identity.

Keller first captured the public's attention when she graduated from Radcliffe in 1904, when she began advocating for both the blind and the deaf populations. After several years, she found advocating for both the deaf and the blind was too complex. Keller changed her focus to the needs of the blind. As a result of this transformation, her identity as a deaf woman began to vanish. To further emphasize her new identity, in Helen Keller’s Journal, 1936 - 1937, she wrote a controversial statement suggesting being deaf was more burdensome than being blind. Additionally, Keller’s close relationship and work with Alexander Graham Bell

, contribute to the skepticism many culturally deaf individuals feel about her. By choosing the blind identity, she lost an important connection to the deaf community. Though Keller felt the need to choose her identity, not all deafblind individuals feel the need to do so. Using Keller's situation as a case study, it is possible to observe issues raised by identity within a minority group.
