“…In treating a developmentally disabled adult, Mace et al demonstrated that by issuing a sequence of three to five commands the subject was likely to comply with (high-p commands) prior to issuing a command s/he was unlikely to comply with (low-p commands), compliance to the low-p commands could be dramatically increased. This strategy has been successfully replicated across a variety of populations including autistic children (Davis, Brady, Williams, & Hamilton, 1992;Houlihan, Jacobson, & Brandon, 1994), individuals with selfinjurious behaviors (Horner, Day, Sprague, O'Brien, & Heathfield, 1991;Zarcone, Iwata, Mazaleski, & Smith, 1994), children with social skills deficits (Davis, Brady, Hamilton, McEvoy, & Williams, 1994;Kennedy, Itkonen, & Lindquist, 1995), and individuals who are being noncompliant with specific medical regimens (Harchik & Putzier, 1990).…”
