Which communication system is commonly used by children who are deaf?

Sign language is the preferred communication system for children who are deaf. It is a fully developed language that uses visual-manual modality to convey meaning, allowing for the expression of ideas, emotions, and nuances just like any other spoken language. Children who are deaf often rely on sign language as it is a natural form of communication that they can easily understand and use, particularly in a community of individuals who are also deaf.

Furthermore, sign language promotes social interaction and accessibility in educational settings, providing a rich linguistic environment that supports learning and cognitive development. Unlike other forms of communication listed, such as speech therapy, verbal communication, or written notes, sign language is specifically designed for those who are deaf and is deeply embedded in cultural identity, making it an integral part of their everyday lives.
