Using Progressive Ratio Schedules to Evaluate Edible, Leisure, and Token Reinforcement

Using Progressive Ratio Schedules to Evaluate Edible, Leisure, and Token Reinforcement

Date: May 2013
Creator: Russell, Danielle M.
Description: The general purpose of the current study was to evaluate the potency of different categories of reinforcers with young children diagnosed with developmental delays. The participants were two boys and one girl who were between the ages of seven and eight. In Phase 1, we evaluated the reinforcing potency of tokens, edible items, and leisure items by using a progressive ratio (PR) schedule. For two participants, we found that tokens resulted in the highest PR break points. For one participant, edibles resulted in the highest break points (tokens were found to have the lowest break points). In Phase 2, we evaluated the effects of presession access on the break points of edibles and tokens. This manipulation served as a preliminary analysis of the extent to which tokens might function as generalized conditioned reinforcers. During Phase 2, presession access altered the break points of edibles, but not tokens. The findings of the current study suggest that PR schedules may be useful as a means to better assess certain dimensions of tasks and how they affect reinforcer effectiveness (e.g., amount of effort the client is willing to exert, the duration at which the client willing to work, how many responses the client ...

A Descriptive Analysis of the Use and Effect of a Self-management Project in an Undergraduate Course in Behavior Analysis

A Descriptive Analysis of the Use and Effect of a Self-management Project in an Undergraduate Course in Behavior Analysis

Date: May 2013
Creator: Lamancusa, Michelle
Description: Undergraduate male and female students enrolled in an introductory behavior analysis course with minimal instruction on self-management were given modified exploratory logs to use in a self-management project. Students self-monitored behavior via the log, constructed their own interventions, and reported changes in behavior and extent of success in a write up at course end. Changes in self-reported descriptions in the logs as well as the written results of a pre and post survey of emotional responses were counted. Successful self-management project interventions were reported by most students. Correspondence between planned and actual events increased. Negative reinforcement procedures characterized most students' intervention. Correspondence between events at pre and post and actual log reports was highest at post.

Oral Syringe Training Animals: Indiscriminable and Discriminable Punishment Contingencies

Oral Syringe Training Animals: Indiscriminable and Discriminable Punishment Contingencies

Date: May 2013
Creator: Erickson, Emilie Jane
Description: Animals are commonly trained to perform behaviors during routine husbandry procedures. However, some husbandry procedures have aversive consequences when the real procedure is performed. This commonly results in loss of the trained behavior. The present study assessed whether maintaining the antecedent environmental stimulus conditions between appetitive and aversive outcomes would prevent this effect and, conversely, whether adding a stimulus discrepancy would facilitate this effect. Three domestic rats served as participants in a multiple baseline across participants design with multi-element components. All three rats stopped performing a trained behavior when a discrepant stimulus reliably predicted an aversive outcome. In addition, all three rats continued to perform the same behavior when antecedent environmental stimulus conditions were consistent between aversive and appetitive outcomes. Results are discussed in terms of practical implications for behavior change agents and conceptual implications for learning theory.

The Effects of Homework Sessions on Undergraduate Students' Homework Performance

The Effects of Homework Sessions on Undergraduate Students' Homework Performance

Date: May 2013
Creator: Hamilton, Elissa R.
Description: Experimenters evaluated the effects of a homework session on undergraduate students' homework performance through an adapted alternating treatments design in two introduction to behavior analysis courses. Several participants attended homework sessions; however, homework submission and homework mastery did not vary as a function of homework session attendance or availability. Homework submission remained high throughout the experiment regardless of attendance at or availability of a homework session. Many participants responded that they were not interested in or did not need homework sessions. Participants who attended homework sessions rated them as neutral or helpful overall, with longer time and different time as the most common suggestions for improvement.

Online Lecture As an Alternative Method of Instruction in College Classrooms: Measuring the Effects of Alternating In-class with Online Lectures in Two Sections of an Undergraduate Introduction to Behavior Analysis Course

Online Lecture As an Alternative Method of Instruction in College Classrooms: Measuring the Effects of Alternating In-class with Online Lectures in Two Sections of an Undergraduate Introduction to Behavior Analysis Course

Date: May 2013
Creator: Treacher, Kay G.
Description: Online instruction is becoming increasingly common at universities; however, there is little single subject research concerning the effectiveness of the online lecture format. We investigated whether online lecture could replace in-class lecture in two sections of an undergraduate Introduction to Behavior Analysis course without detrimentally affecting student learning. Using an adapted alternating treatments design, online and in-class lecture formats were counterbalanced across the two course sections. Experimenters collected data on lecture attendance/access, percent correct on the weekly quiz, and student report on lecture format preference. The data show that, within the context of this class, students performed equally in the weekly quiz regardless of lecture format; further, that this is consistent when looking at individual student data and mean data. However, although students stated a preference for online lecture in the questionnaire, a greater percentage of students attended in-class lecture than accessed online lecture.

The Effects of a Programmed Teaching Sequence and Response Card Use with Systematic Feedback on the Acquisition of Time Telling Behavior of 3 Students with Intellectual Disability

The Effects of a Programmed Teaching Sequence and Response Card Use with Systematic Feedback on the Acquisition of Time Telling Behavior of 3 Students with Intellectual Disability

Date: May 2011
Creator: Weatherford, Matthew
Description: Few studies have proposed or evaluated methods to teach telling time. The purpose of this study was to evaluate the effects of differential reinforcement of student responding in the form of response cards to teach three middle school students with intellectual disability to tell time. Participants worked through six training phases. Results showed that correct responding increased from pre-assessment (range of 5.71-14.29% correct) to post-assessment (range of 85-100% correct). Preliminary evidence shows promise in the application of these procedures to teach telling time to middle school students with intellectual disability.

A Schoolwide Tiered Intervention for Increasing Fruit and Vegetable Consumption

A Schoolwide Tiered Intervention for Increasing Fruit and Vegetable Consumption

Date: December 2012
Creator: Mendoza, Blanca L.
Description: Childhood obesity rates in the U.S. are increasing. Increasing intake of fruits and vegetables is one method to combat obesity. The purpose of this study was to examine a tiered approach to fruit and vegetable consumption with 26 children in an inclusive preschool. The first tier included ongoing availability and opportunity to eat fruits and vegetables (exposure). The second tier included programmed consequences (a reward system). A multiple baseline across children and classrooms was used to evaluate the effect of the interventions. The tier one intervention was effective for nine children and tier two was effective for six children. Eleven children, however, did not respond to either condition. Results are discussed in the context of previous research and tertiary interventions.

Does Family Quality of Life Change? Evaluation of a Group Parent-coaching Package

Does Family Quality of Life Change? Evaluation of a Group Parent-coaching Package

Date: December 2012
Creator: Wiles, Amber Marie
Description: Improving family quality of life is an important goal when working with families of children with autism. Researchers have attempted to measure changes by developing indices of quality such as affect, stress, and confidence. The purpose of this study was to examine the effects of a group parent-coaching program on measures aimed at addressing quality: a) parent confidence, stress and affect ratings; b) child affect ratings; c) the frequency of coordinated joint attention (CJA); and d) parent report of satisfaction and efficacy. Over the course of four weeks, the coaching program involved group presentations, discussions, video sharing, and problem solving, and individual in-vivo coaching sessions regarding specific child skill development. Results from the five parent-child dyads suggested increases in areas associated with quality of life. Results are discussed in the context of quality themes and mixed methods research.

The Use of Conjugate Reinforcement in Autism Treatment Programs: a Demonstration and Discussion

The Use of Conjugate Reinforcement in Autism Treatment Programs: a Demonstration and Discussion

Date: December 2012
Creator: Reetz, Stephany Kristina
Description: The effect of a reinforcer on behavior is largely determined by the schedule in which it is implemented. One type of reinforcement schedule that has not been explored extensively is conjugate reinforcement. Previous researchers have used conjugate schedules to evaluate a reinforcer's effects on behavior and as an assessment tool. However, none have explored how to effectively engineer conjugate schedules in applied settings. The current study explores the effectiveness of conjugate reinforcement implemented by several interventionists across a variety of responses, reinforcers, and in a wide range of participants with autism. The results indicated that delivering social, audio/visual, and tangible stimuli in a conjugate schedule resulted in increased durations of various target responses (e.g. social skills, motor skills) and non-targeted measures (e.g., approach, social bids, speed) across participants. Considerations regarding reinforcer and response selection in implementing conjugate schedules in applied settings are provided.

The Effect of High-Probability Request Sequences on Latency to Comply with Instructions to Transition in a Child With Severe Mental Retardation

The Effect of High-Probability Request Sequences on Latency to Comply with Instructions to Transition in a Child With Severe Mental Retardation

Date: December 2010
Creator: Carpentieri, Michelle Lee
Description: This study investigated the effect of implementing high-probability request sequences prior to the delivery of instructions to transition in a child with severe mental retardation. Data were collected on latency to comply with a low-probability request to transition and a modified version of the low-probability request. Implementation of high-probability request sequences resulted in shortened latencies to comply with the modified low-probability request instructing the child to engage in a preferred activity located at the endpoint of the transition.
