Although feedback is a widely used intervention for improving performance, it is unclear what characteristics individuals prefer and what is necessary for it to be effective. The purpose of this study was to systematically extend Simonian and Brand (2022) by addressing the limitations of the study and adding a best-treatment phase. During an acquisition phase, participants received either positive, corrective, or no feedback upon task completion. Nine of 10 participants mastered the task that was associated with corrective feedback, and one participant mastered the task with no feedback. Eight participants completed a preference phase in which they were provided a choice of either positive or corrective feedback when learning to play a novel game. Half of the eight participants showed a preference for corrective feedback, and the remaining participants had mixed preferences. Overall, corrective feedback was more efficacious and more preferred than positive feedback.

We conducted a systematic review of studies published in the Journal of Applied Behavior Analysis between 2010 and 2020 to identify reports of social validity. A total of 160 studies (17.60%) published during this time included a measure of social validity. For each study, we extracted data on (a) the dimensions of social validity, (b) the methods used for collecting social-validity data, (c) the respondents, and (d) when social-validity data were collected. Most social-validity assessments measured the acceptability of intervention procedures and outcomes, with fewer evaluating goals. The most common method for collecting social validity data was Likert-type rating scales, followed by non-Likert-type questionnaires. In most studies, the direct recipients of the intervention provided feedback on social validity. Social-validity assessment data were often collected at the conclusion of the study. We provide examples of social-validity measurement methods, discuss their strengths and limitations, and provide recommendations for improving the future collection and reporting of social-validity data.

In synchronous-reinforcement schedules, the duration of behavior directly controls the duration of reinforcement on a moment-to-moment basis. We replicated and extended Diaz de Villegas et al. (2020) by comparing the effects of synchronous reinforcement with two accumulated-reinforcement schedules for increasing on-task behavior for seven preschoolers. One accumulated schedule was the same as the one used in Diaz de Villegas et al. and did not include tokens, whereas the other accumulated schedule included the delivery of tokens within session. Furthermore, we assessed preference for the three reinforcement schedules. The results showed that synchronous reinforcement was effective for increasing on-task behavior for all seven participants. Furthermore, it was most effective for increasing on-task behavior for three out of seven participants and preferred by all participants. For some participants, other schedules were also similarly effective. The results are discussed with respect to implications for application.

Extinction bursts, or temporary increases in rates and intensities of behavior during extinction, can preclude the inclusion of extinction in intervention packages meant to suppress severe challenging behavior. To identify underlying behavioral mechanisms responsible for response persistence and bursting, 69 adults with developmental disabilities completed a low-stakes translational investigation employing a 2 × 2 factorial, crossed, and randomized matched blocks design, with batched randomization logic. In each of the four test groups, we made distinct antecedent manipulations with two value parameters commonly studied through behavioral economics (i.e., demand intensity, P_max) and evaluated the extent to which each of these manipulations influenced target responding during extinction. Although we found statistically significant differences attributable to both parameters, variations in reinforcer consumption relative to demand intensity were most influential across all dependent variables. This outcome implicates consumption relative to demand intensity as both a mitigating and exacerbating preextinction factor that influences the prevalence of adverse collateral extinction effects (e.g., bursts).

This study evaluated how speech disfluencies affect perceived speaker effectiveness. Speeches with filler sounds and filler words at different rates of disfluencies (i.e., 0, 2, 5, and 12 per minute) were created and evaluated by a crowdsourcing service for survey-based research for the speaker's public speaking performance. Increased disfluencies, particularly filler sounds, significantly affected perceptions across most categories, notably at higher rates of filler sounds (i.e., 12 per minute). A low, but nonzero, rate of disfluencies (5 per minute) did not adversely affect perceived effectiveness. These findings suggest that although reducing filler sounds is crucial for optimizing perceived speaking effectiveness, a rate of five or fewer disfluencies per minute may be acceptable.

Despite the efficacy of behavioral interventions, resurgence of challenging behavior (e.g., aggression, self-injury) following successful treatment can still occur. Applied work has focused on identifying treatment-related variables thought to affect the occurrence and magnitude of resurgence. The current study describes the relation between several variables (i.e., phase duration, response rates in baseline and treatment, obtained rates of reinforcement, downshift in reinforcement step size) and resurgence in a retrospective consecutive controlled case series of 46 treatment applications for challenging behavior conducted in an inpatient setting. Only the downshift in reinforcement (e.g., schedule-thinning) step size was correlated with the magnitude of resurgence. These results are consistent with recent findings suggesting that treatment duration and other factors have inconsistent effects on resurgence of challenging behavior.

There are several considerations to address when conducting functional communication training for challenging behavior in a school setting, such as the need for schedule thinning and maintenance across staff and the need to establish a variety of appropriate classroom skills. There are several strategies for conducting schedule thinning following functional communication training and for transferring effects across people or settings. However, there are few examples of these processes in natural settings with relevant caregivers and with long-term maintenance of effects. We implemented a functional assessment and skill-based treatment process with six children with autism in a specialized school setting and extended treatment until challenging behavior was reduced to near-zero levels across multiple staff and settings. Follow-up data indicate that effects were still observed 1 year posttreatment and the use of crisis procedures (e.g., physical restraint) was eliminated for all participants.

Although decades of behavior-analytic studies have focused on decreasing the aggressive behavior of clients, relatively little research has been conducted on preventing injuries for the staff members who implement treatment plans. In this study, three direct-care staff members working with clients presenting with aggressive behavior were taught targeted blocking and distance management techniques designed to keep the clients safe while preventing injuries to the participants. Findings indicated that all staff members acquired the target skills in simulations, after which the skills for two participants generalized to the natural work environment.

Multiple-baseline-across-word-sets designs were used to determine whether a computer-based intervention would enhance accurate word signing with four participants. Each participant was a hearing college student with reading disorders. Learning trials included 3 s to observe printed words on the screen and a video model performing the sign twice (i.e., simultaneous prompting), 3 s to make the sign, 3 s to observe the same clip, and 3 s to make the sign again. For each participant and word set, no words were accurately signed during baseline. After the intervention, all four participants increased their accurate word signing across all three word sets, providing 12 demonstrations of experimental control. For each participant, accurate word signing was maintained. Application of efficient, technology-based, simultaneous prompting interventions for enhancing American Sign Language learning and future research designed to investigate causal mechanisms and optimize intervention effects are discussed.

Basic and retrospective translational research has shown that the magnitude of resurgence is determined by the size of the decrease in alternative reinforcement, with larger decreases producing more resurgence. However, this finding has not been evaluated prospectively with a clinical population. In Experiment 1, five participants experienced a fixed progression of reinforcement schedule-thinning steps during treatment of their destructive behavior. Resurgence occurred infrequently across steps and participants, and when resurgence did occur, its clinical meaningfulness was often minimal. In Experiment 2, five new participants experienced these same schedule-thinning steps but in a counterbalanced order. Resurgence occurred most often and was generally largest with larger decreases in alternative reinforcement programmed earlier in the evaluation. Large decreases in alternative reinforcement may be more problematic clinically when they occur earlier in treatment. Whether larger transitions can be recommended in the clinic following the success of smaller ones will require additional research.
