Impact of Deaf-Blindness on Learning
Typically, learning and development occur as children use their vision and hearing to interact with their surroundings.
These distance senses increase engagement with a world that exists beyond the boundaries of their physical bodies. Children learn from watching others, observing objects and actions, and listening to voices and other sounds. Deaf-blindness, however, depending on its severity, impacts a child’s attraction to and subsequent interest in and interaction with the environment.
The world of a child with deaf-blindness is limited to what can be gathered from other senses, particularly touch, and any available vision or hearing. Without appropriate intervention, this limited access leads to isolation that affects a child’s development and learning. The more severe a child’s deaf-blindness, the narrower the world from which they can learn and the more important the sense of touch becomes. Understanding the severity of a child’s deaf-blindness is the first step in helping the child expand their learning to the world beyond their reach.

When both vision and hearing are compromised, the combined effects create a barrier that blocks or distorts significant amounts of information. This creates a chronic problem with gathering information throughout an individual’s lifetime. Students cannot learn what they do not detect, and they may be unaware of what they are missing.
