“…MM adds an element of intrigue to the reinforcement contingencies. The efficacy of MMs has been demonstrated in a number of studies with various populations, including students diagnosed with emotional disturbance (Kehle, Bray, Theodore, Jenson, & Clark, 2000;Theodore, Bray, & Kehle, 2004), Head Start preschoolers (Murphy, Theodore, Aloiso, Alric-Edwards, & Hughes, 2007), elementary school students (Kelshaw-Levering, Sterling-Turner, Henry, & Skinner, 2000;Kowalewicz & Coffee, 2014;Madaus, Kehle, Madaus, & Bray, 2003), and high school students (Schanding & Sterling-Turner, 2010). It has been used to reduce off-task and disruptive behavior (Kehle et al, 2000;Murphy et al, 2007) and to improve homework completion (Madaus et al, 2003;Moore, Waguespack, Wickstrom, Witt, & Gaydos, 1994).…”
