Children deprived of touch, movement and sound (in an orphanage, for example) may exhibit SID. They may be: overly sensitive to touch, movement, sights or sound; under-reactive to sensory stimulation (such as pain); seek out intense sensory experiences (body whirling); show co-ordination problems or delays in speech, motor skills or academic achievement.
A child with SID can't respond to sensory information in order to behave in a meaningful, consistent way; and may also have trouble planning and organizing, and thus have trouble learning.
Which children have SID? It's usually a considerable, though secondary, problem for children with fetal alcohol syndrome and often interferes with the development of children adopted after stays in orphanages. It may also be found in children with learning disabilities or attention deficits.
Carol Stock Kranowitz defines SID as the inability to process information received through the senses. She says that the child doesn't function smoothly, not because she won't, but because she can't. She has a disorganized brain and consequently disorganized behaviour. She could have enormous trouble doing ordinary tasks and responding to everyday events. --- taken from HERE!
Sensory processing is the “procedure in which we take in sensory messages from our bodies and surroundings. Then we interpret these messages and organize our purposeful responses. This occurs when information about sensations is passed back and forth between the central nervous system (CNS) and nerves in the brain and spinal cord, and the peripheral nervous system with the nerves that are outside the CNS” (Kranowitz, 2004). Sensory intake is happening constantly to each of us as we move through our daily endeavors and we respond accordingly. We receive all input through our senses...
