  • Title: Using progressive ratio schedules to evaluate tokens as generalized conditioned reinforcers.
    Author: Russell D, Ingvarsson ET, Haggar JL, Jessel J.
    Journal: J Appl Behav Anal; 2018 Jan; 51(1):40-52. PubMed ID: 29193060.
    Abstract:
    The properties of operant reinforcers are dynamic and dependent on a number of variables, such as schedule and effort. There has been sparse research on the generalized conditioned properties of token reinforcement. We evaluated leisure items, edible items, and tokens using a progressive ratio schedule with three children with diagnoses of ASD and developmental delays. The highest break points occurred during the token reinforcement condition for two out of three participants, but response rates tended to be higher with edibles. We then evaluated the effects of presession access to edibles on the break points of edible items and tokens with two participants. Break points decreased only in the edible reinforcement condition, and the participants chose to work for leisure items rather than edibles when presession access to edibles was in place. These findings suggest that the tokens functioned as generalized conditioned reinforcers.
