“…Since this initial study, numerous researchers have found evidence that interdependent group-oriented contingencies could be used to reduce inappropriate classroom behaviors (Bowman-Perrott, Burke, Zaini, Zhang, & Vannest, 2016;Flower, McKenna, Muething, Bryant, & Bryant, 2014;Stage & Quiroz, 1997). More recently, researchers used interdependent group-oriented contingencies to reduce hallway transition times (Campbell & Skinner, 2004;Hawkins, Haydon, Denune, Larkin, & Fite, 2015;Hine, Ardoin, & Foster, 2015;Yarbrough, Skinner, Lee, & Lemmons, 2004). Campbell and Skinner (2004) worked with a sixth-grade teacher to develop the Timely Transitions Game (TTG), which involved the application of interdependent group rewards with randomly selected criteria.…”
