Procedural fidelity is an important component of behavioral intervention programs. The "Train-to-Code" software was used to teach skilled observation of implementation of three types of discrete-trial programs, and improvement to procedural fidelity was assessed. Participants completed a training package that involved coding video…

Behavior analysts are expected to provide high quality services to autistic individuals/individuals with ASD. Quality behavior intervention requires the interventionist to demonstrate critical thinking skills, in-the-moment analysis, flexibility, and clinical judgment (J.B. Leaf et al., 2016a; J.B. Leaf et al., 2016d, Soluaga et al., 2008). Yet,…

Response-prompting procedures are a form of systematic direct instruction based on the principles of ABA. Researchers have identified six specific and distinct response-prompting procedures for teaching both academic and functional skills: (1) graduated guidance; (2) most-to-least prompting; (3) system of least prompts; (4) progressive time delay;…

We evaluated the use of behavioral skills training (BST) to train caregivers to conduct procedures commonly associated with mand training. We trained two caregivers on the following procedures: (a) conducting preference assessments, (b) delivering preferred items contingent on appropriate behavior, (c) capturing and contriving motivating…

After a 3-step guided compliance procedure (vocal prompt, vocal plus model prompt, vocal prompt plus physical guidance) did not increase compliance, we evaluated 2 modifications with 4 preschool children who exhibited noncompliance. The first modification consisted of omission of the model prompt, and the second modification consisted of omitting…

The purpose of this study was to compare the effects of simultaneous prompting instruction with high and low treatment integrity on the learning of children with developmental disabilities. Low treatment integrity was defined as not delivering a controlling prompt during 30% of the teaching trials. Three preschool children with autism and…

This investigation compared the effectiveness and efficiency of constant time delay (CTD) and simultaneous prompting (SP) procedures in teaching discrete social studies facts to 4 high school students with learning and behavior disorders using an adapted alternating treatments design nested within a multiple probe design. The results indicated…

The acquisition of new skills may be hindered when teaching procedures vary from previously validated approaches or contain errors. In the present study, we compared the acquisition and maintenance of response chains taught using a perfectly implemented system of least prompts and a multiple verbal prompts procedure (i.e., addition of multiple…

The purpose of this study was to evaluate the effectiveness of using a video iPod as a prompting device for teaching three job-related tasks to a young man with developmental disabilities in a community-based employment setting. The effectiveness of the prompting device was evaluated using a multiple probe across behaviors design. Results…

A study found simultaneous prompting procedures were effective in teaching environmental word identification to five students (ages 6-11) with moderate intellectual disabilities and that they were able to acquire additional instructive feedback stimuli presented on either a continuous or an intermittent presentation schedule, regardless of…

Reports of 36 studies using the constant time delay procedure with discrete behaviors of special needs students were analyzed. Results are described in terms of demographic variables (e.g., type of subjects, settings, behaviors, instructors, and instructional arrangements), the procedural parameters of the strategy, strategy effectiveness, and…

A study of 4 youths (ages 11-18) with autism examined the effectiveness of teaching appropriate affective behavioral responses. Participants were described by teachers as having flat and inappropriate affect. Treatment consisted of modeling, prompting, and reinforcement. The combination of an error-correction procedure and contingent delivery of…

Given the frequency with which the "system of least prompts" is used, it is important to identify procedures to enhance the effectiveness and efficiency of the system. This study compared effects of a traditional least to most procedure (TLM) and a revised least to most procedure (RLM) on skill acquisition in individuals with moderate and severe…

This report summarizes the results of research studies on instructional practices that significantly affect the cognitive, language, or mental abilities of students with disabilities. The investigation reviewed current research on instruction of students with moderate disabilities and sought to identify effective instructional practices. The steps…
