The third
most common developmental disability, autism appears before age three. Autism probably
affects the brain's cerebellum, which filters and routes incoming sensory information,
like a computer's CPU. Sounds, images and touch send signals to the brain for processing.
Signals move through the cerebellum to coordinate responses to sensation. Preliminary
research indicates some autistic people may lack critical neurons or have immature neurons
in their cerebellums!
Autism creates a hyper-
or hypo-sensitivities in the senses. Hyper-sensitivity means magnified sensations: soft
sounds (like humming fluorescent lights) are painfully loud to autistic people.
Hypo-sensitivity means the volume is turned down: some autistics ignore loud noises,
suggesting deafness. Hyper- and hypo-sensitivities in hearing, touch, etc. affect reason,
social interaction and speech. Autistic children have difficulty listening and talking
because sound is either painful or unheard! Light touch disrupts calm and focus. Many
soothe their frazzled senses through hand flapping or rocking.
Because
their senses perceive differently, autistic people interpret situations differently. They
"incorrectly" anticipate the responses of neurologically typical people. Change
or new situations surprise them when they focus on irrelevant details. Initially, autistic
people prefer predictable objects: flicking a switch turns the light on or off. The
reaction of people is not easily predicted. Interaction is intimidating because facial
expressions, body language and voice inflection are confusing until the code is broken.
Children with autism befriend others through trial and error, memorizing rules for making
friends!
