Input Disability
Input Disabilities: (Collecting Information): Information enters the brain through all five senses. With learning, the most important ones are visual and auditory. Input is a central process and does not refer to visual or knowledge; it refers to the process of recording information in the brain. Since input refers to how one sees, hears, or perceives the world, the description for this essential process is perception. Therefore, a child might have a visual perceptual or an auditory perceptual disability.
Information arrives at the brain as impulses, transmitted along neurons, primarily from our eyes – called "visual input" – and from our ears – called "auditory input." This input process takes place in the brain. It does not pertain to visual problems, such as nearsightedness or farsightedness, or to any hearing problems. This central input process of seeing, or hearing, or in any other way taking in or perceiving one's environment is referred to as "perception." Thus we speak of a child who has a perceptual disability in the area of visual input as having a visual perceptual disability, and one with a disability in the area of auditory input as having an auditory perceptual disability. Some children have both kinds of perceptual disabilities, or they may have problems when both inputs are needed at the same time – for example, seeing what the teacher writes on the blackboard while listening to the explanation of what is being written.
This relates to how the child's brain translates the information that it receives. It has nothing to do with external issues such as far sighted or the child being hard of hearing. Rather, this is about what the brain does to the information that the eyes and ears absorb. Dyslexia is an example of an input disability. It is one of the language-based learning disabilities that cause a person to have trouble understanding written words. It may also be referred to as reading disability or reading disorder.
