J. Sigafoos et D. Pennell, NONCONTINGENT APPLICATION VERSUS CONTINGENT REMOVAL OF TACTILE STIMULATION - EFFECTS ON SELF-INJURY IN A YOUNG BOY WITH MULTIPLE DISABILITIES, Behaviour change, 12(3), 1995, pp. 139-143
This study examined the effects of tactile stimulation on self-injurio
us behaviour (SIB) in a 10-year-old boy with developmental disabilitie
s. SIB occurred at high rates during unstructured play, suggesting an
automatic reinforcement, sensory stimulation function. Noncontingent a
pplication of an alternative source of tactile stimulation produced on
ly modest reductions in SIB, but contingent removal of the objects use
d to obtain tactile stimulation produced clinically significant reduct
ions.
