“…Interestingly, the antecedent‐based treatments that were implemented by Harper et al (2013) failed to increase prosocial behavior even though they have been demonstrated to be effective in establishing a wide array of stimuli as reinforcers (Axe & Laprime, 2017; Dozier, Iwata, Thomason‐Sassi, Worsdell, & Wilson, 2012; Dudley, Axe, Allen, & Sweeney‐Kerwin, 2019; Greer, Singer‐Dudek, Longano, & Zrinzo, 2008; Helton & Ivy, 2016; Holth, Vandbakk, Finstad, Marie Grønnerud, & Mari Akselsen Sørensen, 2009; Rodriguez & Gutierrez, 2017; Taylor‐Santa et al, 2014). This failure to replicate may be because, in previous studies, the stimuli to be conditioned were presumably neutral, whereas in Harper et al (2013) social interaction was aversive.…”
