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

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.

Effect of Resource Availability on Dyadic Fitness

Description: College students participating in dyads played a game designed as an analog of early hunters whose survival, as a dyad and ultimately individually, depend on rabbits they hunt. Dyadic fitness was defined as both participants being able to hunt and it was measured by the proportion of trials in a condition that both participants hunted. The effects of scarcity (alternating rich and poor conditions) on dyadic fitness were examined in two experiments. First experiment results did not show a difference in dyadic fitness as a function of the independent variable. The second experiment increased the number of hunting seasons and also the discrepancy between scarcity in rich and poor seasons. Second experiment results show that dyads start fit in rich seasons and become increasingly fit in poor seasons. External variables could not be ruled out; therefore, additional experiments still need to be carried out to clarify results.

The Effects of a Communication Training Workshop on the Verbal Behavior of Caregivers

Description: This study evaluated the effectiveness of a workshop designed to train adults to use supportive verbal behavior during distressful situations. Participants were trained to provide descriptive, empathetic and hopeful statements using instructions, rationales, modeling, role-play, feedback, and rehearsal. A pre-post design was used to analyze the effects of the training on verbal and non-verbal behaviors of four females during simulation scenarios. Results indicate all four participants provided maximum support statements above pre-training levels during post-training simulation and written assessments.

Effects of a Computer-based Self-instructional Training Package on Novice Instructors’ Implementation of Discrete Trial Instruction and a Naturalistic Developmental Behavioral Intervention

Description: Discrete trial instruction (DTI) and naturalistic developmental behavioral interventions (NDBIs) are often incorporated into early intensive behavioral interventions for young children with autism. Recent advances in staff training methods have demonstrated that self-instructional manuals, video models, and computer-based training are effective and efficient ways to improve staff implementation of these teaching strategies however research in this area is limited. The current evaluation assessed the effects of a computer-based training package including self-instructional manuals with embedded video models on direct-care staff’s implementation of DTI and an NDBI. All participants’ DTI teaching fidelity increased during role-plays with an adult and with a child with autism and all participants increased teaching fidelity across untrained instructional programs. In addition, moderate improvement was demonstrated following NDBI training on the use of correct prompts, environmental arrangements, and response interaction. Together, these results indicate that therapists are able to acquire a large number of skills using two teaching techniques, DTI and NDBI, following brief computer-based training.

The Effects of a Group Parent-coaching Package on the Behavior of Children with Autism and Their Parents

Description: Support for parents is an important part of treatment programs for children diagnosed with autism. Parent training programs have generally focused on prescribed goals in one-on-one training settings with measures directly related to the goals. Of interest here are the few studies that included collaborative goals, expanded measures, and group training. Benefits of such approaches include the establishment of natural communities of reinforcement and better understanding of the breadth of effects. The purpose of this study was to determine if a group coaching approach would be effective in changing a large range of parent and child skills. This experiment involved group sessions (presentations, discussion, video sharing, and problem solving) and three individual in-vivo coaching sessions. The intervention took place over the course of four weeks. Direct measures included a parent skills checklist and child target behaviors. Results indicated an overall improvement on most measures that maintained or improved at follow-up.

The Effects of a Human Trafficking Prevention Workshop Package on Participant Written and Simulation Responses

Description: This study evaluated the effects of a community workshop designed to teach community members about human trafficking prevention. Participants were trained to identify the critical and non-critical features of human trafficking and safe ways to respond to identified trafficking situations. A pre-post treatment design was used to assess the effects of a community workshop across written and verbal target behaviors. This included written responses as well as simulation assessments across five different trafficking scenarios. Results indicate that all participants engaged in more correct responding within the written assessment and asked specific relevant questions with greater confidence within the simulation assessment following training. However, social media and empathy responses following the workshop did not differ from baseline. This study is one of the first empirical studies aimed at formally evaluating the effects of human trafficking prevention workshops. Results are discussed in the context of instructional design, measurement of outcomes, and interdisciplinary collaboration.

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

Description: 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. The duration of parent-child synchronous engagement maintained at high levels and slightly increased.

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

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.

The Effects of Capturing and Searching on the Acquisition of a Simple Arm Position

Description: The present experiment compared two methods of training a simple arm position using auditory feedback: capture and search. The participants were four right-handed female college students. During capture, auditory feedback was delivered by the experimenter after the participant moved along a single axis into the target position. During search, auditory feedback was produced by the computer after the participant left clicked a mouse inside the target location. The results of a multi-element design showed that participants performed more accurately during capture training than search training. Pre-training and post-training probes, during which no auditory feedback was provided, showed similar fluctuations in accuracy across probe types. A retention check, performed seven days after the final training session, showed higher accuracy scores for search than capture, across all four participants. These findings suggest that TAGteach should incorporate an approach similar to search training to improve training outcomes.

Effects of Conditional Discrimination Training on Symmetry and Semantic Priming

Description: Psychologists interested in the study of language find that people are faster at making decisions about words that are related than they are at making decisions about words that are not related – an effect called semantic priming. This phenomenon has largely only been document in laboratory settings using natural languages as contest and real words as stimuli. The current study explores the relation between the semantic priming effect and a laboratory procedure designed to give rise to performances that can be described as linguistic. Six adult participants learned to partition a collection of eight stimuli into two sets of four stimuli. Following this, the subjects showed the semantic priming effect within a set of stimuli but not across sets. These data suggest that it may be possible to study linguistic phenomenon in laboratory-based procedures allowing better control and the ability to ask very precise questions about linguistic functioning.

The Effects of Copying Before, Copying After, and Guessing on Acquisition Rate and Retention

Description: Computer-based instructional programs are being used more frequently in classrooms. While these programs offer many benefits from traditional teaching methods, humans still need to program them. There is inconsistency in the literature regarding the best way to design such programs. The purpose of this study was to evaluate the effects of three training procedures in teaching individuals to type a specified three-letter response in the presence of a corresponding symbol. Results show that the training format that prompted individuals to copy the correct response before the opportunity to respond was more efficient than viewing the correct response after an error, or copying the correct response after an error. A discussion of the results as well as implications for classroom use is also provided.

The Effects of Feedback Timing when Teaching a New Task to Children with Autism

Description: The purpose of this experiment was to investigate Tosti's proposal about the timing of feedback. The study examined whether it is better to correct immediately after the error occurs or whether it is better to wait until immediately before the next opportunity to respond. In addition, it aimed to determine whether corrections delivered at different times produced different learner affects. Four children with autism were taught to label two sets of pictures under the two different conditions. Results showed that the timing of the feedback yields similar results in regards to number of correct responses and total trial count. However, in regards to time spent in teaching and learner affect, correcting errors before the next opportunity to respond showed to be the more efficient procedure and produced more favorable affect.

The Effects of Fines on Cooperation in a Four-Person Prisoner’s Dilemma Game

Description: Cooperation is an important area of investigation for behavior analysis. The prisoner’s dilemma game (PDG) provides a useful scenario for studying cooperation in a behavior analytic paradigm. The PDG can be coupled with the concept of the metacontingency to investigate how various contingency arrangements support and promote cooperation in a group. Players in this experiment participated in a PDG and, in some conditions, were given the ability to fine other players but could not talk. The goal of this experiment was to investigate how players’ ability to fine one another affected the players’ patterns of cooperation, and whether fining itself was affected by the addition of a shared group consequence. The data show that participants cooperated in some conditions, but the fines did not seem to affect players’ rates of cooperation.

The Effects of Fluency-Based Instruction on the Identification of Component Reading Skills

Description: This study examined the effects of fluency-based instruction on the identification of six component-composite relations for early reading skills. Five participants (ages 5-8) who struggled with reading participated. A multiple probe design was used to assess the effects of frequency building on prerequisite skills on the emergence of composite reading skills. The results show that the prerequisite skills taught did not have an effect on the composite skill probes but did have an effect on the assessment scores. The data expand the research pertaining to Precision Teaching, fluency-based instruction, and component-composite relations. These data suggest that additional skills may be needed to be taught in order to effects on the composite skills. In addition, these authors identify the need for the identification of the component skills necessary to teach rapid autonomic naming.

The Effects of Homework Sessions on Undergraduate Students' Homework Performance

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.

The Effects of Increasing Rates of Reinforcement Through an Alternative Fluent Behavior on the Acquisition and Extinction of Behavior in Dogs

Description: The purpose of the present study was to experimentally investigate the effects of interspersing the opportunity to perform a fluent behavior during the acquisition of a new behavior. The experimenter trained left and right paw movements in domestic canines using a multiple treatment design. One paw movement was trained with a typical shaping procedure while the other was trained with an opportunity to perform a fluent behavior, touching the dog’s nose to a plastic disc, following each successive approximation in the shaping procedure. Two extinction phases were implemented during the experiment. The results showed that higher rates of reinforcement were achieved primarily following changes in criteria for reinforcement for the behavior in acquisition. There were no effects on rate of acquisition of the behavior, but adding an alternative fluent behavior may have slowed the differentiation between the reinforced behavior and alternative behaviors for one dog. The behavior trained with the addition of an alternative fluent behavior extinguished more quickly than in the control condition and extinguished at similar rates to the opposite leg movement. This suggests that the technique of offering an alternative fluent behavior may facilitate the chaining of the opposite behavior with the behavior targeted for reinforcement.

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

Description: 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.

The Effects of Model Prompts on Joint Attention Initiations in Children with Autism

Description: The general purpose of the current study was to evaluate the effects of minimally intrusive prompting procedures and preferred stimuli on protodeclarative joint attention initiations in children diagnosed with autism spectrum disorder (ASD). Two boys and one girl diagnosed with ASD participated. The experimenter provided attention and social interaction following protodeclarative initiations throughout all phases of the study. During intervention, a model prompt was delivered every 30 s if the participant failed to initiate a bid for joint attention. Results for the first participant show that a model prompt was sufficient to increase the rate of protodeclarative initiations across stimulus sets. Generalization was seen across sets, but not across environments. Subsequently, the model prompt was sufficient to increase the rate of protodeclarative initiations across sets in a second setting (classroom). Results for the second participant are inconclusive. Data collected during the initial baseline condition show that she engaged in an incompatible verbal response across sets. When pictorial stimuli depicting highinterest items and activities were introduced, the rate of protodeclarative initiations increased over time. We then returned to original baseline condition and saw an initial decrease, followed by a steady increase in the rate of protodeclarative initiations. The third participant withdrew prematurely due to medical reasons. The findings of the current study show that minimally intrusive prompts and natural consequences may be sufficient to establish protodeclarative initiations in children. However, this finding may be limited to only those children for whom social interactions already function as reinforcers.

The Effects of Naturalistic Language Interventions in Children with Autism

Description: Several evidence-based procedures based upon operant learning principles have been developed to teach language, and for young children with autism spectrum disorder (ASD), naturalistic interventions are commonly implemented as they are both effective and developmentally appropriate. The current investigation compared contingent responsive intervention and combined intervention on the effects of language use in four children diagnosed with ASD. Results suggest that a combined intervention procedure increases target language and requests in children with simplified language (e.g., one-word phrase) as well as complex language (e.g., simple sentences).

The Effects of Price and Durability on Individual Discounting Functions When Purchasing Hypothetical Goods in a Simulated Internet Store

Description: Online shopping has rapidly expanded in the last decade. Online shopping necessarily imposes delays on all transactions. Behavior analysis has long studied the effects of delay on choice. Additionally, a number of researchers are beginning to study consumer behavior using a behavior-analytic approach. The current study attempted to extend research focusing on consumer behavior in online contexts. The experimenters attempted to evaluate whether goods acquire functional properties and whether these properties influence consumer choice. The researchers were specifically interested in studying acquisition costs and durability and in simulating a natural online shopping environment. Results from the current study extend the findings showing that delay and price influence choice. The data from the current study provide mixed evidence for control by item durability.

The Effects of Programmed Reinforcment and Chained Mastery Criteria on Yoga Pose Performance in Two Young Children with Autism

Description: Community exercise can offer many benefits for children, including the opportunity to engage in physical activity and interact with peers in a social setting. Children with autism do not engage in as many community activities as their typical peers. This study examines conditions to teach young children to complete yoga poses to mastery. The effects of prompting, programmed reinforcers, and a chaining criteria were evaluated using a comparison design with two baselines and one intervention condition, replicated across two children with autism. Both children mastered performance of all four targeted yoga poses. The findings are discussed in the context of previous research on the benefits of yoga.

Effects of Reinforcer Magnitude on a Fixed Time Food Delivery Treatment of Pica

Description: The purpose of the current study was to examine the effects of using fixed time schedules with different magnitudes of stimulus delivery as treatment for pica. A functional assessment was conducted, which indicated that pica occurred across experimental conditions and was most frequent in the absence of social stimulation or contingencies. A competing stimulus assessment was then conducted to identify stimuli that could potentially compete with pica during NCR. Subsequently, an evaluation of the effects of reinforcer magnitude on NCR as a treatment of pica was conducted. Treatment results indicated that quantity of reinforcer increased the effectiveness of leaner schedules of reinforcer delivery; however, it was not possible to fade the temporal schedule to one that would have been useful in practice. In addition, limitations and future research are outlined.

The Effects of Sucrose on Ethanol Consumption in Ethanol Naïve and Non-naïve Rats

Description: Sucrose fading and intermittent access are two common procedures that induce alcohol consumption in rodents. Sucrose fading procedures involve exposing ethanol naïve rats to a mixture of ethanol and sucrose and gradually reducing the concentration of sugar. Intermittent access procedures involve providing rats with access to ethanol on alternating days. Given that rats will consume ethanol without sucrose, the role of sugar in the sucrose fading procedure is unclear. Rats must be ethanol naïve when they are exposed to treatment with sucrose fading, so there is no point of comparison to show that exposure to sugar in sucrose fading produces higher levels of drinking. There has yet to be any work that isolates the effects of sugar on the consumption of alcohol. The purpose of the present experiment was to examine the effects of sucrose on ethanol consumption in rats with different alcohol histories. Two groups of six rats were exposed to two successive sucrose fading procedures, 30 days apart and their drinking was measured 30 days after each one. One group was exposed to an intermittent access procedure to establish drinking prior to treatment with sucrose fading, the other was ethanol naïve. Following sucrose fading, all rats drank pharmacologically active doses of ethanol. For both groups consumption correlated with the concentration of sucrose and decreased in a step-wise manner as it was faded. For the ethanol experienced rats, consumption dropped below baseline levels as sucrose was faded and decreased further with the second exposure. In contrast, the ethanol-naïve rats did not decrease consumption from the first sucrose fading procedure to the second. Slight differences in peak force of responses were also observed.

The Effects of Textual Fluency on the Rate of Acquisition and Application of Intraverbal Relations

Description: Intraverbal behavior governs core elements of academic and intellectual behavior. These intraverbal relations can be explicitly taught when an individual is prompted to provide an appropriate response with pictures, text, or other stimuli following a verbal stimulus. It is possible that a focus on fluency of the target repertoires may lead to more conclusive data. the current study assessed the effects of precision teaching based instruction for component textual repertoires on the acquisition of intraverbal relations. Specifically, this study compared the effectiveness of two textual prompting procedures (with and without fluency-based instruction) on the acquisition and application of intraverbal relations using time-delay and a carefully controlled set of intraverbal stimuli. Results indicate that the use of textual prompts and an errorless time-delay transfer of stimulus control procedure were effective strategies for teaching intraverbal responses regardless of the inclusion of fluency-based instruction.
