Remember the processes involved in sensory integration. Those children having difficulty with certain senses or activities may need to put extra effort into those actions. They may, for example, need to focus their full attention on balance or listening and be unable to process different input at the same time. Sensory input can be a powerful force. Children may react by becoming excited or withdrawing from stimuli.
Sensation can have a dramatic effect on the nervous system.
Sensory input can involve both active and passive involvement. When a child actively participates they must initiate, plan and execute movement. Passive activities may provide sensation, but not necessarily require a response. Active involvement provides the best opportunity for changes in the brain that lead to growth, learning, and better organization of behavior.
