Previous studies on skill acquisition have taught targets in stimulus sets composed of different numbers of stimuli. Although the rationale for selection of a stimulus set size is not clear, the number of target stimuli trained within a set is a treatment decision for which there is limited empirical support. The current investigation compared the…

Despite the effectiveness of function-based treatments, most clinicians do not conduct functional analyses (FA). The time required to conduct an FA is a major barrier preventing their use. One way to increase FA efficiency is to discontinue the analysis as soon as it has produced clear results. Saini et al. (2018) evaluated a structured procedure…

The current study evaluated whether a computer-based training program could improve observers' accuracy in scoring discrete instances of problem behavior at 5x normal speed using a multiple-baseline design across subjects. During pretraining and posttraining, observers attempted to score multiple examples of problem behavior at 5.0x without…

Using instructional strategies based on derived relational responding (DRR) to teach foreign-language targets may result in emergent, untrained foreign-language relations. One benefit of using DRR instructional strategies is the efficiency with which an individual acquires additional stimulus relations as a result of emergent responding following…

The traditional recommendation for sequencing speaker and listener instruction has been to teach listener skills prior to teaching speaker skills. In a review of the research literature prior to 2011, Petursdottir and Carr (2011) concluded that research did not support this recommendation. We reviewed the most recent research on the efficiency of…

The current study examined the outcome of presenting multiple secondary targets in learning trials for individuals with autism spectrum disorder. We compared conditions in which (a) a secondary target was presented in the antecedent and consequence of trials, (b) two secondary targets were presented in the consequence of trials, (c) one secondary…

The Internet and information and communications technologies (ICTs) have been found to produce meaningful social interactions and greater social support among older adults (White et al., [White, H., 2002]). Despite these benefits, the Internet and ICTs are not widely used among the older-adult population (Cresci, Yarandi, & Morrell, [Cresci,…

We replicated and extended the study by Koegel, Dunlap, and Dyer (1980) by examining the effects of 3 intertrial-interval (ITI) durations on skill acquisition in 2 children with autism spectrum disorders. Specifically, we compared the effect of short (2 s), progressive (2 s to 20 s), and long (20 s) ITIs on participants' mastery of tacts or…

We replicated and extended the findings of Haq and Kodak (2015) by evaluating the efficiency of massed and distributed practice for teaching tacts and textual and intraverbal behavior to 3 children with autism. Massed practice included all practice opportunities conducted on 1 day during each week, and distributed practice included practice…

Previous research supports the use of a variety of error-correction procedures to facilitate skill acquisition during discrete-trial instruction. We used an adapted alternating treatments design to compare the effects of 4 commonly used error-correction procedures on skill acquisition for 2 children with attention deficit hyperactivity disorder…

Prior research shows that learners have idiosyncratic responses to error-correction procedures during instruction. Thus, assessments that identify error-correction strategies to include in instruction can aid practitioners in selecting individualized, efficacious, and efficient interventions. The current investigation conducted an assessment to…

Because it employs an emergent-learning framework, equivalence-based instruction (EBI) is said to be highly efficient, but its presumed benefits must be compared quantitatively with alternative techniques. In a randomized controlled trial, 61 college students attempted to learn 32 pairs of proprietary and generic drug names using computer-based…

Changing the scheduling system in a pediatric outpatient clinic from time-based (15-minute block scheduling) to problem-based (more extensive treatment needs scheduled for longer time blocks) resulted in a substantial decrease in waiting time by patients across all presenting problems and in increased availability of extra staff time.

The study compared the effectiveness of a traditional training procedure (least-to-most restrictive prompt sequence) and a prescriptive training procedure (utilizing ongoing behavioral assessment data to identify discriminative stimuli) with four severely/multiply handicapped students (ages 11-19). Results indicated both procedures were effective…

Four students, aged 15-19, with moderate mental retardation learned to cash checks and use an automatic teller through either a decreasing prompt hierarchy or time-delay procedure. Both strategies led to acquisition of target tasks and were equally effective in producing performance maintenance; however, the decreasing prompt hierarchy was more…
