AbstractAmong the developmental milestones related to language and communication in early childhood, one that has been the subject of considerable research is response to name (RTN). Delayed or absent RTN in early childhood is a diagnostic marker for autism spectrum disorder and a target behavior in many early intervention curricula. This article describes two related studies. Study 1 evaluated the efficacy and efficiency of a behavioral screening‐to‐intervention model for RTN proposed by recent research. Overall, trials to mastery were reduced relative to previous research. Study 2 evaluated the efficacy of using behavioral skills training to teach caregivers to implement a RTN intervention with their child after that intervention was successful in a clinical setting. Generalized improvements in RTN with caregivers sometimes occurred but did not maintain without programmed reinforcement. Subsequent behavioral skills training was associated with increases in both child RTN and caregiver intervention fidelity.

AbstractWhen applied to functional analysis results, structured visual inspection criteria have resulted in improvements in the levels of agreement between raters as well as earlier identification of the function of challenging behavior. However, multistep criteria can be difficult to apply in real time, which could be a barrier to widespread adoption in practice. This study evaluated a Microsoft‐Excel‐based functional analysis decision support system (FADSS), which could aid behavior analysts with interpreting functional analysis results. Final overall agreement between the FADSS and post hoc visual inspection was high at 95%. Final overall agreement between the post hoc results generated by FADSS and ongoing results generated by FADSS was acceptable at 81%, representing a 50% increase in efficiency. These results indicate that FADSS could aid behavior analysts when interpreting functional analysis results in real time.

AbstractMany researchers have evaluated how characteristics of feedback may influence trainee performance, but relatively little attention has been allocated to directly assessing trainee preference for feedback characteristics and its relation to performance. Thus, the primary purpose of this study was to use a within‐subject experimental design to directly assess trainee preference for the frequency of feedback and its relation to task performance. A secondary objective was to evaluate how trainee preferences varied across specific task components based on component complexity. Thirty‐five undergraduate students completed two arbitrary tasks and were given the opportunity to request feedback after each component of the task. For 85.71% of our participants, an inverse relation was observed between preference for feedback frequency and task performance. Participants requested feedback less often as performance improved. Feedback preferences also varied with the complexity of each component of the task. Implications for training, supervision, and feedback practices are discussed.

AbstractWe assessed whether novel praise statements could be used to (a) maintain and increase responses with existing reinforcement histories and (b) teach a previously untaught response among children diagnosed with autism spectrum disorder across two experiments. During response–stimulus pairing, two responses resulted in preferred edibles but only one also produced a praise statement. In the absence of edibles, the response continuing to produce praise tended to persist more. Next, reversing the praise contingency tended to increase the other response. However, in no case did contingent delivery of those same praise statements result in the acquisition of untaught responses. These findings suggest that conditioning praise statements could serve different functions (antecedent or consequence) depending on the reinforcement history for particular responses.

AbstractEdible and leisure items are often used in behavioral intervention to teach skills or reduce problem behavior. Social interactions, however, have also been shown to function as reinforcers for both typically developing children and children diagnosed with autism. Previous research has been conducted investigating preference displacement between edible, leisure and social items. The current study included edible stimuli and social interactions to evaluate whether patterns of displacement would appear with typically developing children. Multiple stimulus without replacement preference assessments were conducted to identify highly preferred stimuli from both edible item and social interaction classes to use in combined assessments to evaluate displacement. Three of six participants showed complete displacement of social interactions by edible items and three participants showed patterns of partial displacement. Two of the participants demonstrating patterns of partial displacement showed a disproportionate preference for social interactions.

AbstractContingency management is a well‐validated behavior change intervention; however, the financial incentives can prevent it from being widely adopted. Most Americans have a smartphone with applications (apps) that they find enjoyable and engage with for a considerable amount of time. A potential avenue for contingency management dissemination is a mobile smartphone application that leverages the existing reward value of smartphone apps as a tool for behavior change. The present study examined the acceptability of the Re‐Connect concept, which proposes to block nonessential but highly preferred apps and unlock them contingent on meeting the user's health goals. Out of the sample surveyed (N = 146), 63.02% reported that they would be likely to use Re‐Connect and 67.81% would recommend it to someone. Acceptability of Re‐Connect increased with greater user control. These results suggest that access to preferred smartphone apps could be a socially acceptable incentive in a contingency management intervention.
