Sensory modulation dysfunction, one pattern of SPD, usually includes (a) individuals who are overresponsive (i.e., hyperreactive, sensory sensitive, and sensory avoiding) and who experience sensations that most individuals perceive as benign as aversive, uncomfortable, and/or painful; (b) individuals who are underresponsive (e.g., hyporeactive, low sensory registration) and who are slow to respond or have a muted response to sensory experiences of typical intensity; and (c) individuals who are sensory cravers (e.g., sensory seekers) and who have an insatiable need for sensation beyond what is observed in typically developing individuals (Miller, Coll, & Schoen, 2007).
