Module III: Intervention of Sensory and Motor Issues in Individuals
with Asperger’s Syndrome
Behaviors That May Reflect Poor Sensory Processing
The following table shows some of the behaviors that person’s
with Aspergers Syndrome may exhibit due to decreased ability to
modulate and discriminate various sensory input. There are both
sensory seeking and sensory avoiding behaviors depending on the
issues. For example, one child might seek out messy play as a way
to keep his or her system alert and to learn new skills while another
child might avoid messy play at all costs because he or she is
“defensive” to tactile input. That is, the person has
an emotional or behavioral response to a stimulus that is out of
proportion to the stimulus itself. These examples both describe
tactile dysfunction, however are representative of two different
types of dysfunction. Most commonly, person’s with sensory
defensiveness exhibit the avoidance behaviors in the chart below.
The seeking behaviors listed below can help improve overall arousal
level and help try to better organize the nervous system. The seeking
behaviors can also improve sensory discrimination for improved
body scheme awareness, tactile skill development, and auditory
and visual attention and processing. These are only some behaviors
and there are certain to be others not mentioned here.
