EFFECTS OF A MOTIVATING OPERATION MANIPULATION ON THE MAINTENANCE OF MANDS

Abstract

We assessed the maintenance of newly acquired mands under presession reinforcer access (reinforcer efficacy abolished) and no presession reinforcer access (reinforcer efficacy established) conditions with 3 children with autism spectrum disorder. Results suggested that the no presession access condition established the value of the reinforcer and evoked responding relative to the presession access condition. Results are discussed in the context of implications for assessing maintenance of previously acquired skills.
