According to the Sensory Processing Disorder Foundation:

Sensory Processing - is the way the nervous system receives information from the senses (touch, smell, taste, hear, sight, balance, and movement) and turns them into appropriate motor and behavioral responses. In order to catch a ball you need to be able to visually track the ball and then coordinate your muscles to bring your hands together to catch the ball.

Sensory Processing Disorder - is a condition that exists when sensory signals do not get organized into appropriate responses. The late Jean Ayres PhD, pioneering occupational therapist and neuroscientist, describes sensory processing disorder as a “traffic jam”. This prevents certain parts of the brain from receiving the needed sensory information. A person with sensory processing disorder finds it difficult to accurately code the information from the senses for an appropriate response. Children with SPD may have challenges with motor coordination, attention to task, schoolwork, body awareness, behavioral problems and other difficulties.

According to Ahn, Miller, Milberger, & McIntosh (2004) 1 in 20 children are affected by sensory processing disorder.

"Sensory Processing Disorder can affect people in only one sense–for example, just touch or just sight or just movement–or in multiple senses. One person with SPD may over-respond to sensation and find clothing, physical contact, light, sound, food, or other sensory input to be unbearable. Another might under-respond and show little or no reaction to stimulation, even pain or extreme hot and cold. In children whose sensory processing of messages from the muscles and joints are impaired, posture and motor skills can be affected. These are the 'floppy babies' who worry new parents and the kids who are clumsy and overactive on the playground. Still other children exhibit an appetite for sensation that is in perpetual overdrive. These kids often are misdiagnosed - and inappropriately medicated - for ADHD" (

Below you will find helpful information regarding sensory processing disorder. Sensational Kids is one of our favorite books. It is easy to read and Dr Miller does a fantastic job explaining the different symptoms in sensory processing disorder.
