An Analysis Of The Effects Of Extinction Relative To Baseline Measures Including And Excluding Consumption Time, Kelti Keister

Thesis Projects

Extinction bursts are a widely discussed phenomenon. The data analysis methods used to analyze the effects of extinction bursts have not been examined thoroughly within the field of applied behavior analysis, however. In this study, we implemented extinction procedures in a reversal design on three typically developing pre-school aged individuals. We then conducted two different data analysis methods. First, extinction effects were evaluated relative to one baseline measure including reinforcer consumption time and one baseline measure excluding reinforcer consumption time. Second, extinction was evaluated at the whole- and within-session (last five minutes of baseline and first ten minutes of extinction) …

Comparison Of Differential Effects Of Interpolated And Intermittent Reinforcement On Extinction Resistance: A Simulated Study, Cara D. Baxter

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

Schedules of reinforcement explain when a reinforcer may be delivered. Among the different schedules exists continuous (CRF), intermittent (INT), and extinction (EXT). When employing a CRF, reinforcement is delivered following every occurrence of the target response. An INT schedule includes varying the delivery of reinforcement. While both of these schedules include the delivery of reinforcement, EXT means that reinforcement is no longer delivered for the target response (Lee & Belfiore, 1997). Studies have shown that behaviors may be less resistant to extinction if moved from an INT schedule to a CRF schedule than if EXT followed the INT schedule alone. …

Effects Of Commission Errors During Noncontingent Reinforcement, Stephanie Hope Jones

Graduate Theses, Dissertations, and Problem Reports

Noncontingent reinforcement (NCR) is a behavioral treatment in which a reinforcer is provided at set intervals independently of responding. Although NCR is commonly used, effects of inconsistent implementation (i.e., implementation with integrity failures) during NCR were previously unknown. The current study included six participants, but full-integrity NCR suppressed problem behavior for only three participants. Thus, we evaluated effects of one kind of integrity failure, reinforcement of problem behavior, on NCR outcomes for three children who engaged in inappropriate vocalizations maintained by access to tangible items. Effects of commission errors were idiosyncratic across participants.

Development Of A Reinforcer Dimension Sensitivity Assessment To Inform Differential Reinforcement Of Alternative Behavior Without Extinction Procedures, Katherine Brown

Theses & Dissertations

Differential reinforcement of alternative behavior (DRA) is the most commonly used procedure to treat destructive behavior maintained by social-positive reinforcement (Petscher, Rey, & Bailey, 2009). Several studies have demonstrated that placing destructive behavior on extinction (EXT) during DRA is critical for the reduction of destructive behavior (Fisher et al., 1993; Hagopian, Fisher, Sullivan, Acquisto, & LeBlanc, 1998). Despite the empirical evidence demonstrating the importance of using EXT during DRA, the use of EXT has several limitations. These limitations have resulted in the development of DRA without EXT treatments, during which practitioners manipulate dimensions of reinforcement to favor appropriate responding. The …

The Use Of An Individualized Levels System And Extinction To Increase Task Compliance And To Decrease Aggressive Behavior With A Child With Autism, Savanna A. Chojnacki

MSU Graduate Theses

In a token economy level system, as an individual progresses from one task level to the next, there is an increase in the demand of tasks and an increase in the magnitude of reinforcers earned. The motivation for the individual in level systems stems from the increasing of value of reinforcers earned at each level. In this study a level system in concordance with an extinction procedure for aggressive behaviors was employed as a behavioral intervention. In this single-subject design study, a 5-year-old boy with autism was observed across a variety of 15 minute teaching sessions, implementing synchronously, the reinforcement …

What Is An Extinction Burst?, Kristal Huffman

Capstone Projects

Abstract

This paper will explore the effects of extinction, specifically the extinction burst. Extinction is known to be an effective and necessary process in decreasing specific behaviors (Iwata, Pace, Kalsher, Cowdery, & Cataldo, 1990). During this process, side effects might occur and the extinction burst is one of those side effects. Extinction bursts might be a problematic side effect, especially during treatment of severe behavior. This paper will explore the extinction burst in detail as well as how the term is used in both the basic and applied literature. Next, an investigation of the extinction burst as a technical term …

Refining Noncontingent Reinforcement Treatments Using Behavioral Momentum Theory, Valdeep Saini

Theses & Dissertations

One of the most effective and commonly prescribed treatments for children with autism and/or an intellectual disability who engage in severe destructive behavior is called noncontingent reinforcement (NCR). During NCR, the consequence that previously reinforced destructive behavior is delivered on a time-based schedule, independent of destructive behavior, and the contingency between destructive behavior and its reinforcer is discontinued (operant extinction; EXT). Conceptual and quantitative derivations of behavioral momentum theory (BMT) suggest that certain aspects of NCR may inadvertently promote persistence of destructive behavior, thereby prolonging the treatment process. Guided by Shahan and Sweeney’s (2011) model of resurgence based on BMT, …

Reinstatement Of Second-Order Fear, Matthew Nelson

USC Aiken Psychology Theses

The purpose of this study was to determine if, after conditioning and extinction of a second-order stimulus, reinstatement of extinguished fear could be produced. The findings of Holmes et al. (2014) do not support reinstatement of second-order fear following post-extinction presentation of the unconditioned stimulus (US). The present study provides a second attempt at uncovering reinstatement following extinction of second-order conditioning. Rat subjects were randomly assigned to 5 groups (n=12), which received first- and second-order conditioning with Light and Tone counterbalanced. Responding to the second-order stimulus (S2) was extinguished through S2-alone presentations for all but the control subjects (Group NE-NR). …

Generalization Of Fear Effects In Reinstatement To A Discrete Stimulus, Lauren Best

USC Aiken Psychology Theses

The purpose of this study was to investigate generalization of reinstated fear effects to a discrete stimulus. McAllister and McAllister (2006) reported that reinstated fear could generalize over time to similar contexts. The present study aimed to determine if reinstated fear could generalize to similar or different stimuli than conditioning after a long delay between reinstatement and testing. Rat subjects were randomly assigned to six groups (n = 10) which received conditioning and extinction to a 3000 Hz tone. Reinstatement conditioning was then conducted with either the same, similar, or different CS as used in conditioning. Testing for reinstated fear …
