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 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.

Oral Syringe Training Animals: Indiscriminable and Discriminable Punishment Contingencies (open access)

Oral Syringe Training Animals: Indiscriminable and Discriminable Punishment Contingencies

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 (open access)

The Effects of Homework Sessions on Undergraduate Students' Homework Performance

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.

Using Progressive Ratio Schedules to Evaluate Edible, Leisure, and Token Reinforcement (open access)

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

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 (open access)

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

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.

An Observation of Early Parent-Infant Social Interactions in Relation to the Emergence of Joint Attention in the Natural Environment (open access)

An Observation of Early Parent-Infant Social Interactions in Relation to the Emergence of Joint Attention in the Natural Environment

Early interactions between parents and infants are thought to be critical of later development. In particular joint attention has been an area of research and investigations. This study sought to measure joint attention behaviors in infants from 5 to 33 weeks of age under naturalistic conditions: in the home with the mother as the interaction partner given no instructions. Videotapes of the infant-parent interactions were observed and data were collected on behaviors related to joint attention. Given observations occur at younger ages than other studies considered, engagement data results indicate increasing trends for 3 of the 5 infants observed while the direction of infant gaze results indicate patterns consistent with descriptions currently in the literature. Parent behavior data indicate high levels of support in engaging infant attention. Furthering an understanding of joint attention by observing at earlier ages in infant development may be useful in informing teaching programs for infants who have not developed joint attention skills.

Further Evaluation of Blocked Trials to Teach Intraverbal Conditional Discriminations: Effects of Criterion-level Probes (open access)

Further Evaluation of Blocked Trials to Teach Intraverbal Conditional Discriminations: Effects of Criterion-level Probes

Individuals with autism often have deficient intraverbal repertoires. Previous research has found success in using a blocked trials procedure to facilitate discrimination training. A previous study (unpublished) from our laboratory extended this procedure to intraverbal training. The current study continued this line of research by exploring the outcomes of probing the criterion performance more frequently. Three children with autism, ages 7-13, participated. Eight question pairs were taught. One question was presented repeatedly until a specified number of consecutive correct responses occurred, then the other question was presented. Contingent on specific mastery criteria, the trial blocks were faded into smaller blocks until the questions were presented in quasi-random order. Between each step, a criterion probe was conducted to determine if further steps were necessary. The procedure has been successful for two of the three participants. Criterion probe performance showed that not all teaching steps were needed every time. The procedure may have facilitated acquisition over time, because the number of trials to mastery generally decreased over successive targets.

Shall We Dance? Teaching Parents the Communication Dance to Enhance Generalized Communication in Their Children

Children diagnosed with autism exhibit deficits in communication that impact their ability to control their immediate environment. Recent research on mand training has been criticized for producing a limited number of mand topographies over a long span of time with limited generalization to novel environments. There is a body of research, however, that successfully establishes larger repertoires. Training parents as change agents may mediate generalization by teaching under naturally maintaining contingencies. Additional effects of parent training may reduce parent reports of stress, increase favorable quality of parent-child interactions, and increase reports of parental self-efficacy. The current study evaluated the effects of a generalized training framework to teach parents how to target generalized mands and expand their child’s communicative topographies. The effects of the training were evaluated using a non-concurrent multiple baseline across participants and skills. Results indicated that parents were able to effectively teach their child to mand for a variety of items and events and to substantially increase the number of different mand topographies and expand the topographies the child emitted. Parents were observed to have higher overall confidence and lower overall stress following intervention. The current study builds on previous research on generalized teaching strategies for parents that …

Naturalistic Study of College Drinking (open access)

Naturalistic Study of College Drinking

The prevalence of Alcohol Use Disorders is rapidly increasing among college students. The use of real time monitoring in conjunction with contingency management procedures to reduce alcohol consumption has only recently been developed. Therefore, the purpose of this study was to learn more about natural patterns of alcohol consumption in college-aged adults. A second goal was to evaluate a novel, handheld technology for obtaining reliable samples over extended time periods. College students were given a SoberLinkTM SL2 breathalyzer for eight weeks to monitor their drinking behaviors and asked to self-report the number of drinks consumed each day. Participants received one to three text messages per day to provide breath samples and earned monetary rewards for submitting samples within the allotted time. The results of this study showed that college students tend to consume alcohol during the evening hours and mostly on the weekends. There was a weak to medium correlation between average breath alcohol concentration and conditional average drinks. Compliance with prompts ranged between 77 and 84 percent and monetary earnings ranged between $152 and $160. Naturalistic observations of college drinking may aid in the development of interventions to prevent excessive drinking and the SL2 breathalyzer may have great potential …

On the Further Exploration of Interactions between Equivalence Classes and Analytic Units (open access)

On the Further Exploration of Interactions between Equivalence Classes and Analytic Units

Sidman's (2000) theory of stimulus equivalence predicts an interaction between the development of analytic units and the development of equivalence relations. Previous research has documented these interactions (stewart, Barnes-Holmes, Roche, & Smeets, 2002; Vaidya & Brackney, 2014), therefore the current study attempted to replicate the effects seen in Vaidya & Brackney, 2014 (Experiment 2). Baseline conditional discriminations were trained for two sets of three, three-member classes, while participants simply observed stimuli in the third set which was arranged identical to those of Sets 1 and 2. Following equivalence tests where performance met the accuracy criterion of 85% for Sets 1 and 2, participants then entered a simple successive discrimination training phase where common responses were then trained with an equivalence class (pressing the Q key in the presence of A1, B1, or C1), cross equivalence classes (pressing the R key in the presence of A4, A5, or A6), or for stimuli where the participants had experience with them, but the contingencies were never arranged to facilitate equivalence class formation. Results showed a facilitative effect for common responses drawn from within equivalence classes (Set 1), and a retardation effect for common responses drawn from across equivalence classes (Set 2), for three …

Comparing Response Frequency and Response Effort in Reinforcer Assessments with Children with Autism (open access)

Comparing Response Frequency and Response Effort in Reinforcer Assessments with Children with Autism

Reinforcer assessments have largely relied on the use of progressive ratio (PR) schedules to identify stimuli that function as reinforcers. PR schedules evaluate the reinforcing efficacy of a stimulus by measuring the number of responses produced in order to access a stimulus as the number of required responses increases. The current evaluation extends the literature on reinforcer assessments by measuring responding under a progressive force (PF) schedule, in addition to progressive ratio requirements. We compared responding under PR and PF schedules with two children with autism using a multielement design embedded within a reversal experimental design. Results were mixed and implications for further development of reinforcer assessment methods (particularly PF schedules) are discussed.

Evaluating the Effectiveness of a Competency-Based Training Package to Teach Behavior Management Skills to Direct Support Staff (open access)

Evaluating the Effectiveness of a Competency-Based Training Package to Teach Behavior Management Skills to Direct Support Staff

Cooper, Heron and Heward define maintenance as the extent to which a learner continues to perform a target behavior after the intervention has been terminated. Testing for maintenance allows the trainer to see if gains were sustained following the termination of a treatment program. In addition, once it is shown that a learner's skills have remained in the repertoire, assessment of generalization is possible. Previous literature in behavior skills training have assessed maintenance in a variety of settings for a variety of skills. Following maintenance assessments, booster sessions are commonly used to re-train skills that did not maintain at criterion levels. The current project assessed the maintenance of caregivers' skills following a training package used to teach three behavior management techniques (use reinforcement, pivot, protect-redirect) at a large, residential care facility. Procedures were developed to assess caregivers' maintenance of the three behavior management techniques using a pre-test- post-test design. If needed, skills were re-established using 5-20 minute booster sessions. The results showed that time between post-test and maintenance did not seem to have a strong effect on maintenance scores. In general, post-test scores were somewhat indicative of maintenance scores, and patterns were most apparent across tools.

A Behaviorally Planned Community of Practice: A Description and Evaluation of One Area of Staff Development

Staff training packages combining instructions, modeling, practice, and feedback have been shown to be effective in demonstrating skills to work in early intensive behavioral intervention, but maintenance and generalization of the skills trained are often not addressed. Establishing a community of practice, in which staff members continue to learn and develop new skill sets from one another through shared experiences and information, may lead to the endurance and maintenance of desired staff behavior over time. The purpose of the current study is to evaluate the effects of a behaviorally designed community of practice on staff use of socially embedded consequences. The effects of the training procedure were evaluated using a concurrent multiple baseline design across two sites (7 staff members). The results suggest that the behaviorally planned community of practice was effective in reinforcing and maintaining staff use of socially embedded consequences for at least 5 to 9 weeks. Additionally, the number of learning opportunities provided by the staff and social engagement between staff and child increased.

The Effects of a Parent Training Program that is Responsive to Current Repertoire and Affect

Social deficits are one of the defining symptoms of autism spectrum disorder and affect a child’s ability to build relationships with others. These deficits put children with autism at a disadvantage when most of their world is focused on building connections with others – family, friendships, and community ties. Sunny Starts, a service-learning project, was created to specifically meet the needs of families with young toddlers with autism. The primary focus of Sunny Starts is to enhance the quality of the parent-child relationship by teaching parents a basic teaching interaction and to arrange the child’s environment in ways that are mutually reinforcing. The purpose of this experiment is to study the effects of the Sunny Starts DANCE training package, a responsive parent training program, on three levels of parent and child behaviors: 1) teaching episodes, 2) turn taking, social attending, vocal requests, and 3) synchronous engagement. Participants included two parent-child dyads. Parent training included 5-minute video assessments, video review, descriptions, rationales, modeling, practice, and feedback. The effects of the parent training were evaluated using a concurrent multiple baseline across participants. Results indicate parent teaching episodes and child behaviors (turn taking, social attending, and verbal requests) increased during the intervention phase. …

A Clinical Case Study of Rumination and Emesis in an Adult Male with Intellectual Disability

An evaluation of a series of interventions was conducted for an individual who engaged in life-threatening rumination and emesis. There is substantial research indicating that the delivery of peanut butter (Barton & Barton, 1985; Greene, Johnston, Rossi, Racal, Winston, & Barron, 1991) and/or chopped bread following meals (Thibadeau, Blew, Reedy, & Luiselli, 1999), chewing gum (Rhine & Tarbox, 2009), and satiation procedures (Dudley, Johnston, & Barnes, 2002; Lyons, Rue, Luiselli, & DiGennario, 2007; Rast, Johnston, Drum, & Conrin, 1981) can be effective treatments for rumination. In the current case, each of these interventions was found to be either ineffective or contraindicated based on the participant's fragile health status. Previous literature has shown that liquid delivery can affect rates of rumination in some clients (Barton & Barton, 1985,; Heering, Wilder, & Ladd, 2003). We examined how liquid affected the rate of rumination during and after meals. Based on the individual's medical condition, oral nutrition and fluids were discontinued indefinitely and a gastronomy-jejunostomy tube was used for nutrition. All rumination ceased when fluids and nutrition were delivered via the jejunostomy tube. Finally, a fluid analysis procedure was implemented in which the participant received small amounts of fluid while NPO. Color and flavor …

Correspondence between Multiple-Respondent Anecdotal Assessments and Functional Analysis: Analyses of Rank-Order, Magnitude-of-Difference, and Overall Outcomes

We administered the Motivation Assessment Scale (MAS) and the Questions About Behavioral Function (QABF) to five raters and compared the results with functional analysis outcomes for 12 cases in which agreement was obtained for at least four out of five raters on either anecdotal assessment. The scores for functional categories on the MAS and QABF were ranked by averaging the scores for the raters who agreed on the primary maintaining variable. Functional analysis results were ranked by examining average responding across all conditions. A comparison showed correspondence between the highest category and the highest functional analysis condition for 10 out of 11 cases for the MAS and all 10 cases for the QABF. Correspondence for the category and condition ranked second was found for 2 out of 11 cases for the MAS and 2 out of 10 cases for the QABF. The magnitude of difference between categories on the MAS/QABF did not appear to predict the amount of difference in responding in the corresponding functional analyses.

A Further Evaluation of Individual and Synthesized Contingencies within Functional Analysis Methods

Access: Use of this item is restricted to the UNT Community
A functional analysis (FA) is the most commonly used assessment methodology for identifying maintaining variables influencing problem behavior. However, if an FA does not produce clear differentiation, researchers and practitioners often then modify procedures to include additional individualized variables. The interview-informed synthesized contingency analysis (IISCA) provides a marked departure from FA methodology and aims to include individualized factors at the initiation of the assessment in order to more rapidly produce differentiation and clear results. We sought to further evaluate and compare the outcomes of two different functional analysis methods: the single-contingency functional analysis (FA) and the interview-informed synthesized contingency analysis (IISCA) to determine the function of problem behavior and evaluate the subsequent function-based treatment determined from the functional analysis results with two children diagnosed with autism spectrum disorder (ASD). Both participants engaged in problem behavior maintained by single-contingencies of reinforcement identified within the single-contingency FA and emphasized by the effectiveness of each single-contingency function-based treatment.

Looking for Quantitative and Qualitative Measures of Teaching Interactions: A Preliminary Analysis (open access)

Looking for Quantitative and Qualitative Measures of Teaching Interactions: A Preliminary Analysis

Indicators of quality early intensive behavioral intervention (EIBI) include comprehensive interventions, adequately trained staff, high rates of effective instruction delivery, happy interactions between children and their teachers, and socially valid outcomes. When these are in place, high quality EIBI is more likely to increase progress that children with autism make during treatment. When not in place, progress is not as likely, as rapid, or as meaningful. To date, there is limited research regarding the correlation between these indicators of high-quality EIBI and the degree to which their effects are meaningful to direct consumers. The purpose of this methodological study was to compare direct, quantitative measures of teaching interactions (child initiations, teacher initiations, child affect, teacher affect) with qualitative measures (stakeholder ratings of teacher effectiveness, amount of opportunities for interaction and interest in the child) of teaching interactions to determine what sets the occasion for expert stakeholders to describe a teaching interaction as effective, quality therapy.

A Comparison of Observation Systems for Monitoring Engagement in an Intervention Program

The measurement of engagement, or the interaction of a person with their environment, is an integral part of assessing the quality of an intervention program for young children diagnosed with autism spectrum disorder. Researchers and practitioners can and do measure engagement in many ways on the individual and group level. The purpose of this methodological study was to compare three commonly used recording systems: individual partial interval, group momentary time sampling, and group partial interval. These recording methods were compared across three classes of engagement: social, instructional, and non-instructional in a clinical setting with children with autism. Results indicate that group measurement systems were not sensitive to individual changes in engagement when child behaviors were variable. The results are discussed in the context of behavior analytic conceptual systems and the relative utility and future research directions for behavior analytic practice and research with young children in group settings.

An analysis of interrater agreement across multiple respondents on anecdotal assessments was compared with experimental functional analysis outcomes for correspondence. Experiment 1 evaluated the agreement of multiple respondents on the function of problem behavior for 22 individuals across 42 target behaviors using the Motivation Assessment Scale (MAS) and the Questions About Behavioral Function (QABF). Results showed agreement on the primary maintaining consequence for 4 or 5 of the 5 respondents in 52% (22/42) of the individual's target behaviors with the MAS and 57% (24/42) with the QABF. Experiment 2 examined whether correspondence occurred between the anecdotal assessment results and experimental functional analysis (EFA) results for 7 individuals selected from Experiment 1. Correspondence between the QABF assessment and the EFA was found for 6 of 7 participants, and 4 of the 7 showed correspondence between the EFA and the MAS. This study showed that the QABF had higher correspondence with analog assessments than the MAS thus, supporting the previous findings of Paclawskyj et al. (2001).

Evaluating the Effectiveness of a Comprehensive Staff Training Package for Behavioral Interventions for Children with Autism

The effectiveness of behavioral interventions for the treatment of young children with autism has been well documented in professional literature. The success of these procedures, however, depends on the fidelity of implementation and proper training of the therapist. The purpose of this study was to evaluate a 125-skill, comprehensive staff training package that involved a graduated sequence of teaching. In addition to changes in skills, social validity and training time were also assessed. Results indicate that correct demonstration of skills increased following training, incorrect implementation decreased, teachers rated the procedures favorably, and the total training took between 20 and 32.5 hours for over 120 skills to reach mastery criteria. A discussion of the results as well as implications for future research is also provided.

Breaking Accidental Behavior Chains. (open access)

Breaking Accidental Behavior Chains.

Accidental behavior chains are a common problem in dog training. Many handlers inadvertently reinforce undesirable behaviors. The behavior analytic literature already contains articles describing methods of breaking chains; however, those methods either are not used in dog training for practical purposes or are ineffective in dog training. This experiment investigated two ways to break a behavior chain, including extending the chain and introducing a delay into the chain. The results of extending the chain showed that it is possible to decrease the target behavior using this method, but it was not eliminated in this study. Adding a delay into the behavior chain resulted in a quick elimination of the target behavior.

The Effects of Jackpots on Responding and Choice in Two Domestic Dogs

The current study investigated the impact of delivering a jackpot on response rate and response allocation in two domestic dogs. For the purpose of this research, a jackpot was defined as a one-time, within-session increase in the magnitude of reinforcement. Two experiments were conducted to investigate the effects of delivering a jackpot in both single-operant and concurrent schedule procedures. Experiment 1 investigated the impact of a one-time, within-session increase in the magnitude of reinforcement on response rate in a single-operant procedure. Results of Experiment 1 showed no clear change in response rate after the delivery of the jackpot. Experiment 2 investigated the impact of a one-time, within-session increase in the magnitude of reinforcement on response allocation in a concurrent schedule procedure. Results of Experiment 2 showed an increase in response allocation to the jackpotted contingency in both subjects. These results suggest that a jackpot, as defined here, has no effect in single-operant procedures while having an effect in concurrent schedule procedures. These effects are similar to those reported in the magnitude of reinforcement literature.
