AbstractThe purpose of the current study was to conduct a systematic replication of Fiske et al. (2015) to extend the behavior‐analytic literature on token reinforcement. Specifically, the researchers addressed several of the limitations of Fiske et al. by including specific conditioning procedures, creating a controlled history of reinforcement with the token system, including participants with and without disabilities to extend the generality of the findings, and equating the magnitude of reinforcement across the primary and paired‐token conditions. The current study evaluated the reinforcing value of tokens by using progressive‐ratio schedules to compare the efficacy of primary reinforcement, paired tokens, and unpaired tokens. The results suggest that paired tokens may function as reinforcers, but they were not as consistently effective as primary reinforcers.

AbstractDue to the Coronavirus pandemic and lengthy absences from the classroom, there is a need for large‐scale remedial programs to support young children to “catch‐up” on literacy and numeracy skills. A stratified randomized controlled trial was used to evaluate the Headsprout Early Reading (HER) program as a parent‐mediated digital literacy intervention. A between‐groups design compared differences in reading‐dependent outcome measures for 36 children assigned to one of three intervention groups: with support, without support, and waitlist‐control. Children completed significantly more episodes when parents received implementation support from the researcher compared to the without support group. Children receiving Headsprout instructions demonstrated marginally greater gains than the waitlist‐control group in posttest outcome measures; however, differences in reading outcomes were not significant between groups at posttesting. The current research provides tentative support for HER and importantly, highlights the importance of providing support for parents implementing interventions at home.

AbstractIdiosyncratic patterns of speech are common among individuals with autism spectrum disorder (ASD) and can greatly affect their ability to participate successfully in various social and educational settings. We evaluated a treatment package with three children with ASD and a history of loud speech. A multiple baseline across participants design and a decibel meter application were used to evaluate whether the multi‐component intervention (i.e., a rule, differential reinforcement, and in vivo feedback) would effectively reduce participants' rates of loud speech. The results showed that the intervention decreased rates of loud speech for all participants. Results are discussed in terms of (a) their extension of the literature regarding speech prosody in ASD by demonstrating an effective intervention for loud speech, (b) clinical implications, and (c) potential future research regarding this nuanced, yet crucial aspect of social communication, including appropriate methods for addressing loud speech in individuals with ASD.

AbstractShahan et al. (2006) found that the relative rate of pigeons' pecking on two observing responses (i.e., responses that only produced an S+ or stimulus correlated with primary reinforcement) was well described by the relative rate of S+ delivery. Researchers have not evaluated the effects of S+ delivery rate in a concurrent observing response procedure with human subjects, so the necessary procedural modifications for studying the effects of conditioned reinforcement on human choice remain unclear. The purpose of the current study was to conduct an additive component analysis of modifications to the procedures of Shahan et al. (2006). We evaluated the additive effects of introducing response cost, a changeover response, and ordinal discriminative stimuli on correspondence with the results of Shahan et al. and the quality of fits of the generalized matching equation. When our procedures were most similar to those of Shahan et al., we observed low rates of observing and indifference between the two observing responses. For the group of subjects with whom all three additive components were included, we obtained the highest level of sensitivity to relative rate of S+ delivery, but the slope and R2 of our fits of the generalized matching equation were still much lower than those obtained by Shahan et al. Potential reasons for these discrepancies, methods of resolving them, and implications for future research are discussed.

AbstractSelf‐feeding with utensils represents an important step in a child's progression toward age‐typical eating and emerges in the absence of intervention for most children. In contrast, children with feeding disorders may lack the skill or motivation to self‐feed, which impedes progress toward age‐typical eating. In the current study, experimenters used a multielement design to evaluate negative reinforcement in the form of meal termination to transition six participants with a feeding disorder from caregiver‐fed to self‐fed bites and drinks. Caregivers conducted meals in which they fed the participant or prompted them to self‐feed. During self‐fed meal‐termination sessions, participants had the opportunity to end the meal contingent on self‐feeding the presented bite(s) or drink(s). Self‐feeding increased during meal‐termination sessions for all participants. The experimenters discuss these results relative to their potential to inform interventions for children with feeding disorders that progress the child toward age‐typical eating.

AbstractPrevious research has commonly evaluated preference stability over time and across multiple preference assessment administrations. No studies have evaluated shifts in preference across consecutive rounds of a single preference assessment, where rounds refer to each time the experimenter resets the stimulus‐presentation array. The purpose of the present study was to examine the stability of stimulus selections across successive rounds of a multiple‐stimulus‐without‐replacement (MSWO) preference assessment with different classes of stimuli for children with autism. The study involved a secondary data analysis and calculation of preference stability across consecutive rounds using Spearman rank‐order correlation coefficients (Spearman's ) for 17 participants across 40 MSWO preference assessments. Patterns of preference stability were observed in 24 out of the 40 assessments (60%) indicating that children's preferences in this study were slightly more likely to be classified as stable than other observed patterns of responding.

AbstractUnintentional injuries are one of the leading causes of morbidity and mortality among children with intellectual and developmental disabilities (IDD). First aid training involves teaching critical first aid skills, some of which are designed to treat unintentional injuries. To date, no study has (a) evaluated the effects of a video‐prompting procedure to teach first aid skills to children with IDD or (b) attempted to teach these skills to children by using a telehealth delivery format. We used a concurrent multiple‐baseline‐across‐skills design to evaluate the efficacy of a video‐prompting procedure via telehealth to teach five children with IDD to perform first aid on themselves for insect stings, minor cuts, and minor burns under simulated conditions. For all participants, our procedure produced large improvements that maintained for a minimum of 4 weeks. Furthermore, the effects of the training generalized to novel confederates for all participants, and these effects maintained for a minimum of 4 weeks.

AbstractResearchers have observed that preference for edible items may displace preference for leisure items when items from the stimulus classes are assessed together within multiple stimulus without replacement (MSWO) preference assessments. The current study extends previous research by examining patterns of preference and displacement when assessing preference for high‐tech and low‐tech leisure items. We conducted three separate MSWO preference assessments; one assessing low‐tech items, another assessing high‐tech items, and a combined assessment (using the top four high‐ and low‐tech items from the previous assessments) to test for displacement. Preference for high‐tech items fully or partially displaced preference for low‐tech items in five of eight participants. We then conducted concurrent and single operant reinforcer assessments using the highly preferred high‐tech and low‐tech items. Reinforcer assessment results demonstrated similar levels of responding for the highest preferred high‐tech and low‐tech items, indicating that combining high‐ and low‐tech items within preference assessments may influence the validity of results.

AbstractThe purpose of the study was to do an experimental analysis of academic task refusal for one girl with a developmental disability. Task refusal was analyzed in two experimental analyses. First, an analysis testing if the behavior was maintained by negative reinforcement, and the second, an analysis testing if the behavior was the result of transitioning between academic tasks differing in preference. Task refusal did not occur in the demand condition of the functional analysis, indicating that the behavior was not maintained by escape from demands. Conversely, task refusal occurred solely in the second experimental analysis when transitioning from a high‐preferred to a low‐preferred academic task. In this case, the context of terminating a preferred academic task and transitioning to a less preferred academic task was aversive but not the demand itself. In addition, when an embedded break condition was compared to a no break condition in a multielement design, task refusal was reduced to zero levels.
