An Assessment Process And Guide For Intervention To Increase Procedural Fidelity, Silvia Cabal

Thesis Projects

For applied behavior analytic (ABA) services to be effective and provide change, those providing services must be well trained. However, when low procedural fidelity is observed, whether it is due to a skill or performance deficit may be unknown. Assessments can help provide insight into whether low procedural fidelity by a Registered Behavior Technician (RBT) providing services is due to a skill or performance deficit. The intervention can then be tailored to the RBT's specific needs. This study evaluates this process by administering the Performance Diagnostic Checklist-Human Services (PDC-HS) to three RBTs and providing either a reinforcement intervention or behavioral …

Stimulus Pairing To Condition Novel Reinforcers For Bermudian Participants With Autism, Jahnae Harvey

Walden Dissertations and Doctoral Studies

Reinforcement is crucial to an individual’s quality of life and acquisition/maintenance of novel skills, but a limited bank of reinforcers could lead to a reduction in engagement with pre-established reinforcers, reducing the motivational strength to contrive teaching opportunities, and increase maladaptive behaviors, self-stimulatory behaviors, or idle time. Though the stimulus-stimulus paring (SSP) method has been effective in establishing novel reinforcers for individuals who are diagnosed with autism, there is a gap in the literature on cross-cultural variations seen among responses when using SSP. This study was conducted to determine the generalizability of the effect when using the method of SSP …

Evaluating Dro With Asymmetrical Magnitude Of Reinforcement, Lindsey M. Hronek

Graduate Theses, Dissertations, and Problem Reports

Differential reinforcement of other behavior (DRO) is a reinforcement schedule used in behavior analytic procedures aimed at decreasing various forms of challenging behavior. DRO commonly includes a reinforcement component and an extinction component; a reinforcer is delivered on an interval-based schedule dependent on the omission of a target behavior and the reinforcer is withheld following the occurrence of the target behavior (i.e., extinction). Although interventions using DRO can be effective for challenging behavior, procedures that include extinction can at times be impractical or lead to undesirable side effects. A DRO schedule can be implemented without extinction, but previous research has …

Contingent Reinforcement And Instructed Generalization In A Laboratory Analog Of Functional Analytic Psychotherapy: A Mixed Within-Group, Between-Group Design, Rebecca Rausch

Dissertations

Functional Analytic Psychotherapy emphasizes using social interactions in the therapeutic relationship to enhance interpersonal outcomes. The proposed mechanism of action in FAP is reinforcement provided by the therapist responding contingently to client improvements as they occur in session. The result is a stronger therapeutic relationship and improved social relating in daily life. Generalization is expected due to functional similarities inherent in interpersonal interactions and explicit attempts to link in-session learning to clients’ life via verbal descriptions and homework. The present study was a laboratory-based analog of the proposed processes occurring in FAP.

An Experimental Analysis Of The Classic Overjustification Effect In Rats: Does The Removal Of “Expected” Rewards Alter Behavior In Rats As It Does In Humans?, Eleah Sunde

Master's Theses and Doctoral Dissertations

The overjustification effect posits that rewards undermine intrinsic motivation, such that an individual’s engagement in previously intrinsically motivating tasks will decrease when a previously reliable reward is withdrawn. This study aimed to determine if this overjustification effect can be demonstrated in rats, with typical confounds related to social and verbal aspects of reward delivery controlled for. Baseline “intrinsic” wheel-running rates of seven SpragueDawley rats were compared to rates that followed administration and withdrawal of a contingent sucrose reward, and to rates of rats in control conditions (n = 7). Consistent with the author’s hypothesis, the reward group’s wheel-running did not …

Using Two Reinforcement Contingencies To Alter Teachers' Rates Of Praise, Ashleigh Eaves

Dissertations

The current study evaluated the effects of a positive and negative reinforcement contingency on teachers’ use of behavior specific praise (BSP) in the educational setting. An alternating treatments design was used across four participants in a rural, Southern elementary to determine if one or both conditions was successful in increasing the use of BSP. Data were collected on teachers’ use of BSP, general praise, general reprimands, and behavior specific reprimands (BSR). Additionally, student engagement in academically-associated and/or disruptive behaviors was measured throughout baseline, treatment, and follow-up phases. Results indicate both the positive and negative reinforcement contingency were successful in improving …

Naloxone And Ethanol Addiction Reinforcement, Roland T. Smith Iii

Theses and Dissertations

A study was carried out examining how naloxone administered after high-incentive ethanol exposure can interrupt the reinforcing effect of drugs of abuse in C57BL/6 mice. Naloxone was shown to be an effective tool for blunting preferential and motivational behaviors associated with ethanol addiction.

Effects Of A Group-Deposit Prize Draw On The Step Counts Of Adults, Alex J. Mccurdy

University of the Pacific Theses and Dissertations

The World Health Organization (WHO, 2016) reports that 3.2 million deaths per year are attributable to physical inactivity, making it the fourth leading risk factor for global mortality. Physical inactivity is also a key risk factor for noncommunicable diseases such as cardiovascular disease, cancer, and diabetes (WHO, 2018). Globally, 1 in 4 adults is not active enough and, therefore, foregoes a myriad of health benefits associated with Physical Activity (PA; WHO, 2018). In the United States, only about 1 in 5 (21%) adults meet the 2008 Physical Activity Guidelines set by the Centers for Disease Control and Prevention (CDC, 2018). …

What Motivates Children To Respond? Functional Analysis And Intervention Of Math Computation Fluency, Catherine Rose Lark

LSU Doctoral Dissertations

An abundance of research exists supporting the use of functional analyses to assess and treat problem behavior. In contrast, little research has been conducted on the application of functional analysis (FA) procedures to academic behaviors. The current study attempted to fill this research gap by conducting an FA of academic responding for five elementary students with low math fluency. Sessions were conducted using both a traditional reinforcement schedule of a fixed ratio of one (FR-1) as well as a more practical reinforcement schedule of a fixed ratio of ten (FR-10) to examine the effects of the reinforcement schedule on the …

Effects Of Rich And Lean Treatment Contexts On Renewal, Sandhya Rajagopal

Theses and Dissertations

Relapse of problem behavior following behavioral intervention can occur for many reasons, including a change in setting after treatment. Reappearance of a previously extinguished behavior due to a context change is termed renewal. Laboratory models have demonstrated renewal by training a target behavior in one stimulus context, extinguishing the behavior in another context, and testing for relapse in the training context, where the behavior remains in extinction. Basic-research studies of relapse have also shown that conditions of the treatment environment, such as reinforcement schedules, can affect the amount of relapse observed. Assuming that quality of the treatment context could have …

Examining Effects Of Technology Level And Reinforcer Arrangements On Preference And Efficacy, Audrey N. Hoffman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Applied behavior analysts use reinforcement to enact socially meaningful outcomes with the individuals that they work with. Identifying the ways in which reinforcers function optimally is an important consideration for behavioral research. Preference for reinforcers, and how effective reinforcers are, may change depending upon several factors. Two important factors to consider are how reinforcers are arranged and the technology level of the reinforcers used. Reinforcers can be delivered following every response in a distributed manner or they can be delivered following several responses in an accumulated manner. Additionally, leisure items used as reinforcers can be classified according to technology level, …

Characterization Of Sex Differences In The Reinforcing Effects Of Nicotine, Rodolfo Jesus Flores Garcia

Open Access Theses & Dissertations

It is presently unclear whether ovarian hormones, such as estradiol (E2) promote the reinforcing effects of nicotine in females. Thus, we compared extended access to nicotine intravenous self-administration (IVSA) in intact male, intact female, and OVX female rats (Study 1) as well as OVX females that received vehicle or E2 supplementation (Study 2). The E2 supplementation procedure involved a 4-day procedure involving 2 days of vehicle administration and 2 days of E2 administration. Two doses of E2 (25 or 250 ug) were assessed in separate groups of OVX females in order to examine the dose-dependent effects of this hormone on …

The Effects Of Schedule Density Of Reinforcement For Alternative Behavior On Resurgence, Kathryn M. Kestner

Dissertations

Resurgence is the reemergence of a previously extinguished response when an alternative response no longer produces reinforcement. Although returning to previously successful methods for obtaining reinforcement is likely advantageous, resurgence also occurs in the form of treatment relapse. An individual may return to problematic behavior (e.g., aggression, self-injury, drug use) when an alternative behavior (e.g., communication response, coping skill, social behavior, etc.) is no longer successful at producing a reinforcer. Behavior analysts rely on treatments based on differential reinforcement of alternative behavior, and resurgence has been demonstrated following changes to reinforcement schedules due to errors in treatment integrity or intentional …

Contextual Differences In Reinforcement Affect Self-Control In Shr And Wky Subjects, Jonathan C. Rich

Undergraduate Honors Capstone Projects

The spontaneously hypertensive rat (SHR) is the outcome of selectively breeding its progenitor the Wistar Kyoto (WKY) for hypertension. In the present experiment, the context of reinforcement was manipulated to determine its effect on impulsivity across the SHR and WKY strains of rat. An additional block of delays was added onto the end of a standard delay discounting procedure to vary the context of reinforcement from one condition (0 sec.) to the next (60 sec.). Results indicate that both SHR and WKY subjects made fewer impulsive decisions when a shorter delay followed the longest delay in the task - although …

Fixed-Time Schedule Effects On Participant Responding: An Evaluation Of Similar Vs. Dissimilar Schedule Programs Using A Group Design Approach, Jessica Pearl Alvarez

LSU Doctoral Dissertations

We evaluated the effectiveness of fixed-time (FT) schedules of reinforcement at eliminating participant’s responding using a between-subjects group design. Participants experienced one of three conditions; a FT leaner schedule, a FT yoked schedule, or a FT denser schedule using a computerized experimental program. Dependent variables of interest are the total number of responses made during the fixed-time reinforcement phase and the latency until the participant met extinction or exit criteria.

Treatment Integrity Failures Matched To Behavioral Function, Joanna Elizabeth Lomas Mevers

LSU Doctoral Dissertations

Prior research on treatment integrity has focused on either the lack of measurement of the independent variable (Peterson, Homer & Wonderlich, 1982; Gresham, Gansle & Noel, 1993; Wheeler, Baggett, Fox & Blevins, 2006; McIntyre, Gresham, DiGennaro & Reed, 2007; Sanetti, Gritter & Dobey, 2011) or on methods to increase overall levels of treatment integrity(Witt, Noell, LaFleur & Mortenson, 1997; Noell, Witt, Gilbertson, Ranier & Freeland,1997; Noell et al., 2005). Yet little research has been devoted to understanding the effectiveness of common interventions when those interventions are implemented with less than perfect integrity. The current investigation evaluated the effectiveness of using …

Examining The Differential Effects Of The Mystery Motivator Intervention Using Chosen Versus Unknown Reinforcers, Natalie Marie Robichaux

LSU Master's Theses

Disruptive classroom behaviors are among the most prevalent of childhood problems and are associated with reduced instruction time, poor academic achievement, and persistent behavior problems throughout childhood. Class-wide interventions, such as the Mystery Motivator, are an easy and time efficient way to increase the level of classroom management and remediate disruptive behavior patterns. Although the effectiveness of class-wide interventions is well documented, the literature is still inconsistent as to which type of reinforcement is more effective when using behavioral interventions. Some research suggests individuals prefer a choice in reinforcement, while other research suggests choice is just as preferred as reinforcement …

A Punishment-Free, Toilet-Training Protocol For Children With Developmental Disabilities, Chelsea Lynn Pearsall

All Master's Theses

The present investigation adapted a behaviorally-based toilet-training protocol for use with two male children with developmental disabilities. Positive practice and verbal reprimands were eliminated, and reinforcement, scheduled sits, and a urine alarm were utilized. Data were collected on the number of intoilet urinations, urinary accidents, and self-initiations. Results show that both participants exhibited significant improvement in their toileting skills and met the final success criteria rapidly. These results were maintained through follow-up. Implications for the elimination of punishment procedures in future toilet training protocols are discussed.

Avoidance And Depression: Evidence For Reinforcement As A Mediating Factor, John Paul Carvalho

Doctoral Dissertations

Behavioral Activation theory (Martell, Addis, & Jacobson, 2001) posits that a pattern of excessive use of avoidant coping strategies removes an individual from environmental sources of reward and reinforcement and subsequently leads to the development (or maintenance) of depressive symptoms. This investigation examined this theory by establishing measures of environmental reward as mediators between avoidance and depression, while further demonstrating that there is a strong connection between avoidance and depression independent of anxiety. Reward was measured by both self-report questionnaire (Reward Probability Inventory; Carvalho et al., under review) and daily activity diary ratings (Hopko, Bell, Armento, Hunt, & Lejuez, 2003), …

Addressing Response Requirements And Behavioral Costs In Contingency Management For Smoking Cessation, Brantley Phillip Jarvis

Masters Theses, 2010-2019

Despite the efficacy of contingency management (CM) in promoting smoking reduction and abstinence, major barriers continue to hinder its widespread dissemination and adoption. The present study addressed two of these barriers, inefficient response requirements and high behavioral costs, by evaluating a novel payment schedule implemented within a workplace setting. Nine university staff were enrolled in a 6-week ABAB study design. During baseline weeks, participants earned money contingent on session attendance. During CM weeks, participants earned money contingent on smoking reduction or abstention payment arrangements, which were available concurrently. Abstention payments increased in magnitude across treatment weeks whereas reduction payments decreased. …

The Effectiveness Of Electronic Games (Atari) Reinforcers For Increasing Appropriate Behavior In Handicapped Children, James M. Payant

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ten subjects ranging from 9 to 16 years in age with IQ's ranging from 23 to 62 were randomly selected as contingent or noncontingent subjects for two experiments. Five subjects received contingent access to two electronic games for performance within a specified learning session, while five subjects received noncontingent access to the games. These experiments were designed to determine the effect on performance, attending, and compliance skills in the classroom, when contingent access to the electronic games was based on performance. The development of fine motor skills and/or eye-hand coordination skills as a result of game usage was examined. The …

The Effects Of Extrinsic Rewards On Intrinsic Motivation: Reinforcement Theory Or Cognitive Evaluation Theory, Jack S. Leon

Student Work

Intrinsically motivated behaviors are those for which there is no apparent reward except the activity itself. Such rewards are mediated within the individual. Rather than bringing about external rewards, intrinsically motivated behaviors bring about internal states that the individual finds rewarding (Deci, 1975a).

Effectiveness Of Three Differential Reinforcement Techniques As A Function Of Past Reinforcement History And Present Schedule Of Reinforcement, La Rue Chappell

Student Work

The effectiveness of three differential reinforcement techniques, extinction of the old response with reinforcement for the new response versus extinction of the old response with double reinforcement for the new response versus continuation of reinforcement for the old response with double reinforcement for the new response, in reducing lever-pressing behavior, was studied, as a function of past reinforcement history and present schedule of reinforcement. Thirty children, with a mean age of 5 years 10 months, were reinforced for tapping the assigned key on either a differential reinforcement of low rates (drl 10"') or a differential reinforcement of high rates (VR …

Transfer Of Stimulus Control By Temporal Fading, David Allan Steele

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The present study was designed to analyze the transfer of stimulus control in temporal fading procedures. Several aspects of temporal fading procedures were manipulated including sources of inhibitory stimulus control, delays of reinforcement, and rates of increase in the temporal parameter of a fading procedure. In Experiment I, previous research producing transfer of stimulus control in a temporal fading procedure was directly replicated and controls were implemented for the operation of inhibition. The results showed that inhibitory stimulus control is not necessary in order to produce a transfer as participants with neutral stimulus backgrounds also transferred from one dimension to …

Locus Of Control, Schedule Of Reinforcement, And The Attribution Of Freedom In The Reinforcing Agent, Mary Piechowski

Student Work

Attributions of freedom and the probability of ingratiating to another were assessed in terms of the unpredictability of the reinforcement schedule used by the other and the locus of control of the observer using videotapes. Internal subjects viewing.a situation involving either 0%, 10%, 50%, 90% or 100% reinforcement saw more freedom when less reinforcement occurred. In contrast, external subjects saw more freedom in the unpredictable situations (10%, 50%, 90%) but saw little difference between the 0% and; 100% situations. The effect of variations in reinforcement strategy was investigated in a broader context, as well, using sixteen bi-polar trait adjectives. Several …

The Effects Of Increment And Decrement Manipulations On Titration Level Under Interlocking Progressive-Ratio Schedules Of Reinforcement, Dennis Lorbin Nunes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Generally human titration performance under schedules of reinforcement has not been investigated. In an attempt to examine the variables which control titration, an interlocking progressive-ratio schedule was devised. Under an interlocking progressive-ratio schedule, the number of responses required for reinforcement increases by a constant (the increment value) after every ratio, but during each ratio the response requirement can be lowered (the decrement value) by emitting pauses of a specified duration (the stepdown duration).

The first experiment sought to determine if children would titrate when exposed to interlocking progressive-ratio schedules. Although three of the four subjects did not show evidence of …

Non-Contingent Reinforcement In A Counseling Like Situation, Robert B. Shelton Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to determine if a variable, non-contingent reinforcement, could account for a significant amount of the effect of psychotherapy. A sample of ninety subjects was drawn from basic psychology classes and randomly assigned to six groups in a variation of the Soloman 4-group design. The treatment groups were connected to sham GSR equipment and told that when a light flashed they had made an anxiety reducing statement and were becoming more mentally healthy. The subjects were given three by five cards upon which were typed positive-negative adjective pairs and told to use the cards as …

An Analysis Of The Effects Of Delay Of Reinforcement And Momentary Probabilities Of Reinforcement On Interval Schedule Performance, Charles A. Lund

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In two experiments pigeons were exposed to VI and FI schedules and schedules approximating both VI and FI schedules. In experiment I, the probabilities of the VI and FI components in a Mixed FI VI schedule were manipulated to create schedule contingencies approximating simple VI or FI. In experiment II, the minimum and maximum inter-reinforcement intervals were manipulated to create schedule contingencies approximating simple VI or FI. The major finding of both of these experiments was that maximal control by the dimension of time occurred as FI contingencies were approximated. Control by any one temporal value in experiment I depended …

The Effectiveness Of Two Classes Of Verbal Reinforcement On The Performance Of Second-, Fifth-, And Eighth-Grade Children, Douglas D. Settles

Student Work

The effects of two classes of verbal reinforcers, correctness and social, were examined among 108 second-, fifth-, and eighthgrade, middle-class children. The effectiveness of verbal reinforcement. was measured by a change in the S's response preference on a marble-sorting task. Results of the study were (a) that there were no initial age differences in the magnitude or direction of the baserate responses, (b) that correctness reinforcement was more rewarding across all levels of age than social approval, (c) that for eighth-grade Ss, correctness reinforcers were significantly more rewarding than either social or no reinforcement, and (d) that a post hoc …

A Test Of The "Contiguity" And "Generalized Imitation" Theories Of Social Modeling Processes, Gerald R. Adams

Student Work

Imitative behavior was studied using 36 kindergarten children who were either reinforced or not reinforced for imitative behavior prior to observing a male model exhibit aggressive behaviors. The children were tested for imitative aggressive behaviors in an 8-minute freeplay situation using a five category rating scale. The results revealed that the reinforced group emitted significantly more physical, verbal, and nonimitative aggression than the nonreinforced group. A second test examined the retention of the model's aggressive behavior under an incentive condition. The incentive condition diminished the initial differences found in the first test, revealing a nonsignificant difference between the reinforced and …
