The minds of people who are deaf or deafblind have been discussed since ancient times. How is a person who is deaf able to learn a language and how does a person who is deafblind think? From research over the past few decades, we have been able to come closer to an answer to some of these questions. Scientific studies have contributed to a better understanding of the links between sensory loss and language acquisition, risks of mental disorders, and identity formation.
Basic and applied research on the history and future of deaf and deafblind education, visual and tactile language development, and mental health promotion will be discussed.
