Phase Duration And Resurgence, Sean Smith
Phase Duration And Resurgence, Sean Smith
Theses & Dissertations
Resurgence, the recurrence of responding due to a worsening of reinforcement conditions for current behavior, is a prevalent form of treatment relapse. Resurgence as Choice in Context predicts that increasing the duration of exposure to reinforcement for target responding during Phase 1 will increase resurgence magnitude, whereas increasing the duration of exposure to reinforcement for alternative responding and extinction for target responding during Phase 2 will decrease resurgence magnitude. We conducted an experiment evaluating these predictions with human participants recruited through Amazon’s Mechanical Turk platform. We varied Phase 1 and Phase 2 durations across four experimental groups. Resurgence as Choice …
Sustaining Behavior Reduction By Transitioning The Topography Of The Functional Communication Response During Fct, Kayla R. Randall
Sustaining Behavior Reduction By Transitioning The Topography Of The Functional Communication Response During Fct, Kayla R. Randall
Theses & Dissertations
Initial rates of destructive behavior tend to be lower when behavior analysts select functional communication responses (FCRs) they can physically guide (e.g., a card-touch FCR). However, destructive behavior may recur at higher rates when FCR materials go missing than when the FCR no longer produces reinforcement. In Experiment 1, we extended prior research by demonstrating less resurgence of target responding when a vocal FCR remained available but no longer produced reinforcement compared to a condition in which neither the alternative response nor reinforcement was available. In contrast to these findings, Experiment 2 replicated other prior research showing that the ability …

Investigations Of Operant Aba Renewal During Differential Alternative Reinforcement, Ryan T. Kimball
Theses & Dissertations
Operant renewal is a form of relapse in which a previously extinguished response recurs due to a change in context. We designed two experiments to examine the impact of differential reinforcement of alternative behavior on ABA renewal in a translational model of relapse with 12 children either diagnosed with autism spectrum disorder, an intellectual disability, or who were neurotypical. We compared levels of renewal in two, three-phase arrangements. In one arrangement, we reinforced target responding in Context A, extinguished responding in Context B, and returned to Context A while continuing to implement extinction. In a second arrangement, an alternative response …
