“…Stimulating contact by making use of students' intrinsic motivation to interact will result is more permanent effects. Moreover, in several interventions typically developing students were prompted by teachers or assistants when no interaction took place for a predefined amount of time (e.g., Goldstein and Cisar, 1992;Antia et al, 1993;Storey et al, 1993;Frea et al, 1999;Odom et al, 1999;Nelson et al, 2007;Kamps et al, 2015;Lee and Lee, 2015). This might be a good way to start up interactions between students with and without disabilities, however, since the interaction data were often collected during intervention sessions, the positive results are most likely an overestimation of the real voluntary social interactions that took place in day to day classroom activities outside of the intervention (e.g., at the playground).…”
