While surfing for some info, I came upon the official website of the book The Out-of-Sync Child. While reading the “Introduction” page, I found some great thoughts that I want to share with you. They sum up Sensory Processing Disorder so well.
Sensory processing—the ability to organize sensory information for use in daily life.
[While studying children with sensory processing disorder, Carol Kranowitz noticed that these children] had no identified special needs. They weren’t unloved or disadvantaged. Some seemed to misbehave on purpose, like sticking a foot out to trip a classmate, while others seemed to move without any purpose at all, in an aimless or listless manner. Little about their behavior could be classified, except for a shared inability to enjoy the activities that children traditionally relish.
SPD can cause a bewildering variety of symptoms. When their central nervous systems are ineffective in processing sensory information, children have a hard time functioning in daily life. They may look fine and have superior intelligence, but may be awkward and clumsy, fearful and withdrawn, or hostile and aggressive. SPD can affect not only how they move and learn, but also how they behave, how they play and make friends, and especially how they feel about themselves.
