Sensory Processing Disorder was previously called Sensory Intergration Disorder (SID). This is when sensory stimuli is experienced as too intense or too mild compared to typical peers.

Stock Kranowitz, C, (revised 2005) The Out-Of-Sync Child: Recognizing and Coping With Sensory Processing Disorder
For 25 years, I taught at St. Columba’s Nursery School in Washington, DC. Most preschoolers loved my classes involving music, movement, and dramatic play. Every day, small groups of three-, four-, and five-year-olds would come to my room to play, move, and learn. They happily pounded on drums and xylophones, sang and clapped, danced and twirled. They shook beanbags, manipulated puppets, and enacted fairy tales. They waved the parachute, played musical follow-the-leader games, and flowed through obstacle courses. They swooped like kites, stomped like elephants, and melted like snowmen.
Most children enjoy such activities because they have effective sensory processing—the ability to organize sensory information for use in daily life. They take in sensations of touch, movement, sight, and sound coming from their bodies and the world around them, and they respond in a well-regulated way.
Some children, however, such as Andrew, Ben, and Alice, did not enjoy coming to my classroom. Faced with the challenge of sensory-motor experiences, they became tense, unhappy, and confused. They refused to participate in the activities, or did so ineffectively, and their behavior disrupted their classmates’ fun. They are the children for whom this book is written.
