Sensory Processing Disorder
Sensory processing disorder is a generic term used to describe a child’s
inability to integrate sensory stimuli from the environment in order to make
an appropriate response. Sensory processing disorder may also be referred to
as sensory integration dysfunction.
The sensory integration theory was developed by Jean Ayers and is referred
to as having both neurological and behavioral components. When a child has a
well integrated sensory system, he/she is able to take in the information
from the environment (sights, sounds, smells, tastes, touch, and movement),
interpret the information and respond to the information in ways that are
appropriate for the situation. Children with SPD lack the ability to “make
sense” out of the stimuli around them, thus are unable to make necessary
responses that are appropriate.Types of Sensory Processing/Integration Disorders
There are many types of sensory processing disorders. Major categories that
fall under the umbrella of SPD include: Modulation, Sensory Defensiveness,
Modulation refers to the ability to be able to maintain a level of attention
and arousal to learn and respond to the demands of a task effectively.
Children with modulation difficulties may exhibit behaviors that appear to
be overactive and distractible, lethargic and passive, or fluctuating
between these two extremes throughout the day.
