Peer tutoring and token economy to increase approvals and spontaneous interactions for three students with autism

This study tested the effects of peer tutoring (Greer & Polirstok, 1982; Lawson & Trapenberg, 2007) combined with the use of token economy (Ayllon & Azrin, 1968) on increasing approvals and spontaneous interactions in three students with autism spectrum disorder. The participants, aged between 7 and 9 years and with a reader level of verbal development (Greer & Ross, 2008), were selected for the study because they presented a satisfactory repertoire of productive language with adults but no type of interaction with peers was recorded except through the emission of disapprovals. A delayed multiple probe design across participants was used, in which the number of approvals and spontaneous interactions emitted by the participants in non-instructional settings with peers was measured. The intervention consisted in the use of peer tutoring and the implementation of a token economy in order to instruct the tutors in the accurate presentation of learn units (Greer & McDonough, 1999). The results show an increase in approvals and at the same time a decrease in disapprovals, as well as an increase in social interactions which, in this study, were defined as collateral behaviors (Greer & Polirstok, 1982) produced by the introduction of peer tutoring.
