“…This model of functional analysis has been replicated in several hundred studies (Beavers et al, 2013;Hanley et al, 2003). It has been used in assessing the operant function of other topographies of problem behavior besides self-injury (e.g., aggression, property destruction, inappropriate vocalizations, elopement, food refusal, and stereotypy; e.g., Bachmeyer et al, 2019;Boyle & Adamson, 2017;Fisher et al, 2013;Hausman et al, 2020;Saini et al, 2019;Shawler et al, 2020;Wunderlich et al, 2020). It has also been used to illustrate the flexibility of test conditions for other unique sources of social positive reinforcement (e.g., access to leisure items and food) and social negative reinforcement (e.g., the termination of social interactions, medical routines, and loud noises; Harper et al, 2013;Iwata, Pace et al, 1990;McCord et al, 2001;Schlichenmeyer et al, 2013;Tiger et al, 2009).…”
