Sensory integration focuses primarily on 3 basic senses: (1) proprioceptive, (2) vestibular, and (3) tactile. Their interconnections start forming before birth and continue to develop as the youngster matures and interacts with his environment.

Everyone has difficulty processing certain sensory stimuli (e.g., a certain touch, taste, smell, sound, movement etc.) – and everyone has sensory preferences.
