The three models of deafness are rooted in either social or biological sciences. These are the cultural model, the social model, and themedicalmodel. The model through which the deaf person is viewed can impact how they are treated as well as their own self perception. In the cultural model, the Deaf belong to a culture in which they are neither infirm nor disabled, but rather have their own fully grammatical and natural language. In the medical model, deafness is viewed undesirable, and it is to the advantage of the individual as well as society as a whole to "cure" this condition. The social model seeks to explain difficulties experienced by deaf individuals that are due to their environment.
A cochlear implant (CI) is a surgically implanted neuroprosthesis that provides a person who has moderate-to-profound sensorineural hearing loss with sound perception. With the help of therapy, cochlear implants may allow for improved speech understanding in both quiet and noisy environments. A CI bypasses acoustic hearing by direct electrical stimulation of the auditory nerve. Through everyday listening and auditory training, cochlear implants allow both children and adults to learn to interpret those signals as speech and sound.
Lip reading, also known as speechreading, is a technique of understanding a limited range of speech by visually interpreting the movements of the lips, face and tongue without sound. Estimates of the range of lip reading vary, with some figures as low as 30% because lip reading relies on context, language knowledge, and any residual hearing. Although lip reading is used most extensively by deaf and hard-of-hearing people, most people with normal hearing process some speech information from sight of the moving mouth.
Babbling is a stage in child development and a state in language acquisition during which an infant appears to be experimenting with uttering articulate sounds, but does not yet produce any recognizable words. Babbling begins shortly after birth and progresses through several stages as the infant's repertoire of sounds expands and vocalizations become more speech-like. Infants typically begin to produce recognizable words when they are around 12 months of age, though babbling may continue for some time afterward.
Deaf culture is the set of social beliefs, behaviors, art, literary traditions, history, values, and shared institutions of communities that are influenced by deafness and which use sign languages as the main means of communication. When used as a cultural label especially within the culture, the word deaf is often written with a capital D and referred to as "big D Deaf" in speech and sign. When used as a label for the audiological condition, it is written with a lower case d. Carl G. Croneberg coined the term "Deaf Culture" and he was the first to discuss analogies between Deaf and hearing cultures in his appendices C/D of the 1965 Dictionary of American Sign Language.
Jane Fernandes is a Deaf American educator and social justice advocate. As of August 2021, Fernandes is the President of Antioch College in Yellow Springs, Ohio. She previously served as president of Guilford College from 2014 to 2021.
Signing Time! is an American television program targeted towards children aged one through eight that teaches American Sign Language. It is filmed in the United States and was created by sisters Emilie Brown and Rachel Coleman, the latter of whom hosts the series. Between 2006 and 2016, it was syndicated by American Public Television to public television stations across the US. Signing Time! is produced and distributed by Two Little Hands Productions, which is located in Salt Lake City, Utah.
In the United States, deaf culture was born in Connecticut in 1817 at the American School for the Deaf, when a deaf teacher from France, Laurent Clerc, was recruited by Thomas Gallaudet to help found the new institution. Under the guidance and instruction of Clerc in language and ways of living, deaf American students began to evolve their own strategies for communication and for living, which became the kernel for the development of American Deaf culture.
Deaf education is the education of students with any degree of hearing loss or deafness. This may involve, but does not always, individually-planned, systematically-monitored teaching methods, adaptive materials, accessible settings, and other interventions designed to help students achieve a higher level of self-sufficiency and success in the school and community than they would achieve with a typical classroom education. There are different language modalities used in educational setting where students get varied communication methods. A number of countries focus on training teachers to teach deaf students with a variety of approaches and have organizations to aid deaf students.
Prelingual deafness refers to deafness that occurs before learning speech or language. Speech and language typically begin to develop very early with infants saying their first words by age one. Therefore, prelingual deafness is considered to occur before the age of one, where a baby is either born deaf or loses hearing before the age of one. This hearing loss may occur for a variety of reasons and impacts cognitive, social, and language development.
The Deaf community over time has worked to improve the educational system for those who are Deaf and hard of hearing. The history of Deaf education dates back to Ancient Egypt where the deaf were respected and revered. In contrast, those who were deaf in Ancient Greece were considered a burden to society and put to death. The educational aspects of the deaf community has evolved tremendously and still continues to grow as the science of linguistics, educational research, new technologies, and laws, on local, national, and international levels are steadily being introduced. Strategies, however, remain controversial.
The history of deaf education in the United States began in the early 1800s when the Cobbs School of Virginia, an oral school, was established by William Bolling and John Braidwood, and the Connecticut Asylum for the Deaf and Dumb, a manual school, was established by Thomas Hopkins Gallaudet and Laurent Clerc. When the Cobbs School closed in 1816, the manual method, which used American Sign Language, became commonplace in deaf schools for most of the remainder of the century. In the late 1800s, schools began to use the oral method, which only allowed the use of speech, as opposed to the manual method previously in place. Students caught using sign language in oral programs were often punished. The oral method was used for many years until sign language instruction gradually began to come back into deaf education.
Language deprivation is associated with the lack of linguistic stimuli that are necessary for the language acquisition processes in an individual. Research has shown that early exposure to a first language will predict future language outcomes. Experiments involving language deprivation are very scarce due to the ethical controversy associated with it. Roger Shattuck, an American writer, called language deprivation research "The Forbidden Experiment" because it required the deprivation of a normal human. Similarly, experiments were performed by depriving animals of social stimuli to examine psychosis. Although there has been no formal experimentation on this topic, there are several cases of language deprivation. The combined research on these cases has furthered the research in the critical period hypothesis and sensitive period in language acquisition.
Language acquisition is a natural process in which infants and children develop proficiency in the first language or languages that they are exposed to. The process of language acquisition is varied among deaf children. Deaf children born to deaf parents are typically exposed to a sign language at birth and their language acquisition follows a typical developmental timeline. However, at least 90% of deaf children are born to hearing parents who use a spoken language at home. Hearing loss prevents many deaf children from hearing spoken language to the degree necessary for language acquisition. For many deaf children, language acquisition is delayed until the time that they are exposed to a sign language or until they begin using amplification devices such as hearing aids or cochlear implants. Deaf children who experience delayed language acquisition, sometimes called language deprivation, are at risk for lower language and cognitive outcomes. However, profoundly deaf children who receive cochlear implants and auditory habilitation early in life often achieve expressive and receptive language skills within the norms of their hearing peers; age at implantation is strongly and positively correlated with speech recognition ability. Early access to language through signed language or technology have both been shown to prepare children who are deaf to achieve fluency in literacy skills.
The Deaf rights movement encompasses a series of social movements within the disability rights and cultural diversity movements that encourages deaf and hard of hearing to push society to adopt a position of equal respect for them. Acknowledging that those who were Deaf or hard of hearing had rights to obtain the same things as those hearing lead this movement. Establishing an educational system to teach those with Deafness was one of the first accomplishments of this movement. Sign language, as well as cochlear implants, has also had an extensive impact on the Deaf community. These have all been aspects that have paved the way for those with Deafness, which began with the Deaf Rights movement.
Language deprivation in deaf and hard-of-hearing children is a delay in language development that occurs when sufficient exposure to language, spoken or signed, is not provided in the first few years of a deaf or hard of hearing child's life, often called the critical or sensitive period. Early intervention, parental involvement, and other resources all work to prevent language deprivation. Children who experience limited access to language—spoken or signed—may not develop the necessary skills to successfully assimilate into the academic learning environment. There are various educational approaches for teaching deaf and hard of hearing individuals. Decisions about language instruction is dependent upon a number of factors including extent of hearing loss, availability of programs, and family dynamics.
Language exposure for children is the act of making language readily available and accessible during the critical period for language acquisition. Deaf and hard of hearing children, when compared to their hearing peers, tend to face more hardships when it comes to ensuring that they will receive accessible language during their formative years. Therefore, deaf and hard of hearing children are more likely to have language deprivation which causes cognitive delays. Early exposure to language enables the brain to fully develop cognitive and linguistic skills as well as language fluency and comprehension later in life. Hearing parents of deaf and hard of hearing children face unique barriers when it comes to providing language exposure for their children. Yet, there is a lot of research, advice, and services available to those parents of deaf and hard of hearing children who may not know how to start in providing language.
Deaf View Image Art, abbreviated as De'VIA, is a genre of visual art that intentionally represents the Deaf experience and Deaf culture. Although De'VIA works have been created throughout history, the term was first defined and recognized as an art genre in 1989. In 1989, a group of nine Deaf artists gathered at Gallaudet University shortly before the Deaf Way arts festival was being held there. Led by Betty G. Miller, known as the Mother of De'VIA, and Paul Johnston, these artists created a manifesto detailing what De'VIA is and what it includes. Since its official designation as a genre, De'VIA has helped to introduce the Deaf experience to the artistic world and give a new platform to the Deaf community.
Elizabeth English Benson (1904–1972) was an American educator for deaf students who taught at Gallaudet College for two decades before being named Dean of Women there. During World War II, she temporarily joined the military so she could help newly deafened soldiers injured in the war. Later she was an occasional interpreter for two U.S. presidents.
Out of nearly 59 million people in Italy, about 3.5 million Italians have some form of hearing loss. Among them, around 70,000 people are severely deaf. The European Union for the Deaf reports that the majority of the deaf people in Italy use Italian Sign Language (LIS). LIS has been an official sign language in Italy since 2021. Italy, among other countries, ratified the Convention on the Rights of Persons with Disabilities (CRPD) and is slowly improving conditions for deaf humans in Italy. Many major organizations in Italy fight for deaf rights and spread awareness to the Italian National Agency for the protection and assistance of the Deaf and Associated Italian Families for the Defense of the Rights of Deaf and Hard of Hearing Individuals (FIADDA). Newborns in Italy also receive universal hearing screenings. Education in Italy is directed towards oralism, although sign language is also used. LIS is a stable language and is used by approximately 40,000 users in Italy.
