The process of how an individual receives information and processes it based on his/her senses (touch, taste, smell, sound, sight). This may include how one perceives his/her body,and the world around him/her. According to the theory of sensory integration, the many parts of the nervous system work together so that one can interact with the environment effectively and experience appropriate satisfaction. Having poor sensory integration may interfere with activities necessary for daily functioning (e.g. brushing teeth, playing on play equipment, hugging).
