A comparison of consequences for correct responses during discrete-trial instruction

A review of the concurrent-chains arrangement to assess intervention choice: 2018-2023

The purpose of this review is to summarize recent literature on the use of concurrent-chains arrangements in the assessment of preference for interventions (or intervention components) in the applied literature. The types of interventions and participants are described briefly, and procedural variations, ethical considerations, and recommendations for future research are discussed.

A Component Analysis of Skill Acquisition Consequences with Listener Responses

We conducted a component analysis of skill acquisition consequences for correct and incorrect responses. In the learn unit (LU) condition, researchers praised correct responses and implemented a correction procedure contingent on incorrect responses. In the praise-only-for-correct-responses (PC) condition, researchers delivered contingent praise for correct responses and ignored incorrect responses. In the correction-only-for-incorrect-responses (CI) condition, researchers ignored correct responses and implemented the correction procedure contingent on incorrect responses. We manipulated this independent variable across educational and abstract stimuli and measured acquisition rate, duration, and maintenance of responses. The results showed that the LU and the CI conditions were both effective in teaching listener responses and were more effective than the PC procedure. Furthermore, the LU instruction was not necessarily more efficient than the CI condition on acquisition of listener responses. The results suggested that the correction procedure may be necessary and sufficient for skill acquisition and maintenance.

Assessing Parameters of Reinforcement on Efficiency of Acquisition: A Systematic Review

Discrete-trial training (DTT) is a common method of instruction used in early intervention amongindividuals with autism spectrum disorder and related neurodevelopmental disorders and is an effective method of teaching different skills such as tacting, listener responding, and matching. Delivery of effective reinforcers is a key component of DTT. Although general recommendations have been made for effective reinforcement delivery in DTT, no review has synthesized the available research on the efficiency of various reinforcer parameters on efficiency of acquisition. The current systematic review assessed the efficiency of various reinforcer parameters on acquisition in DTT. Results were idiosyncratic, and a general paucity of repeated measures examining specific reinforcer parameters within and across studies was observed. In general, (1) maintaining high levels of treatment integrity, (2) delivery of tangible (i.e. leisure items) or edible reinforcers in comparison with contingent praise as a reinforcer, and (3) delivery of edible reinforcers in comparison with other topographies of reinforcement were the most successful reinforcer parameter manipulations and always resulted in more efficient skill acquisition. The results of this review provide clinicians with information regarding what reinforcer parameter manipulations may be more or less likely to support efficient acquisition. The present review also provides considerations and makes recommendations for future research.

Creating and Sharing Digital ABA Instructional Activities: A Practical Tutorial

Board Certified Behavior Analysts (BCBAs) may encounter situations, such as the current COVID-19 pandemic, that preclude them from providing traditional in-person applied behavior-analytic services to clients. When conditions prevent BCBAs and behavior technicians from working directly with clients, digital instructional activities designed by BCBAs and delivered via a computer or tablet may be a viable substitute. Google applications, including Google Slides, Google Forms, and Google Classroom, can be particularly useful for creating and sharing digital instructional activities. In the current article, we provide task analyses for utilizing basic Google Slides functions, developing independent instructional activities, developing caregiver-supported instructional activities, and sharing activities with clients and caregivers. We also provide practical recommendations for implementing digital instructional activities with clients and caregivers.

Measuring Happiness Behavior in Functional Analyses of Challenging Behavior for Children with Autism Spectrum Disorder

This two-experiment study assessed the utility of measuring happiness behavior (e.g., smiling and/or laughing) within functional analyses (FA) of challenging behavior, and using results to inform interventions for children with autism spectrum disorder (ASD). In Exp. 1, we concurrently measured happiness behavior within the trial-based FA's of challenging behavior of four children with ASD. Results showed differentiation for both challenging behavior in test trials and happiness behavior within controls. In Exp. 2, we compared interventions based on challenging and happiness behavior from FA results for three of the participants, using a multiple-baseline across-participants design, with embedded reversals. Results suggested that interventions derived from measures of the children's happiness behavior led to reductions challenging behavior that were similar to interventions informed by challenging behavior, and were also associated with increased happiness behavior. Taken together, these two experiments suggest that the measurement of children's happiness behavior in FA of challenging behavior appears to be helpful in determining interventions for children with ASD.
