Erratum to: Token Reinforcement of Verbal Responses Controlled by Temporally Removed Verbal Stimuli

In the present study we examined the effects of token reinforcement on the convergent control of immediate and temporally removed verbal stimuli over the verbal behavior of three school-age children with autism who showed specific deficits in intraverbal responding. Throughout the study, participants were systematically introduced to a series of visitors to a university-based autism center, and subsequently probed for information about the visitor they had most recently met. Results show that contingent token reinforcement was effective at establishing control by temporally removed verbal stimuli.
