There is a constant interaction between the senses; visual, auditory, tactile, taste and smell. A dysfunction in one sense can affect the accurate interpretation of the other senses and an individual's ability to interact with the world around them. The sensory experiences that are often experienced by those with autistic spectrum disorders and Aspergers add to their different behaviours. The five senses which are usually talked about in isolation, will sometimes overlap and also be heightened (hyper) or depressed (hypo). Also these levels of sensory information can change and be further confused by the static (white noise) perceived within these senses. This can make it difficult for autistic and non-autistic people to understand the enviromental reactions of each other.
Often autistic behaviour is recognised by the individual's self stimulation (stimming) of sensory input, finger flapping, rocking, tapping, rotatating on the spot,etc. These may be self- discovered behaviours to cope with unwelcome stimulation through one or more of the senses. Seventy percent of the information an individual receives comes in through the eyes and must be correctly interpreted by the brain. Any problem in the way the brain processes information can cause difficulties in the general ability to function.
By the correct diagnosis and prescription of Irlen Lenses one of the senses ie. sight is given some respite from stress, thus allowing the other senses to cope better. There are many reports of Irlen wearers being more able to listen. It is not that the hearing has improved, but that they are better able to process through the sense of hearing because the sense of sight is taking less energy. Results indicate that some individuals suffering from sensory perceptual distortions and overload can be helped by Irlen Filters.
Types of Problems
The types of sensory perceptual deficits associated with autism and Aspergers are unique. These environmental distortions are varied, unpredictable and constantly changing.
For example, parts of the environment may disappear or people may be seen in pieces.
As a result those with Autism / Aspergers may experience the following:
Poor social skills
Low self esteem
Poor body awareness
Faulty information processing
