Self-instruction using videos or other supports on a mobile device is a pivotal skill and can increase independence for individuals with disabilities by decreasing a need for adult supports. This study evaluated the effects of progressive time delay (PTD) to teach four adolescents with autism and intellectual disability how to initiate self-instruction in the presence of a task direction for an untrained task. Participants were screened for imitating video models prior to the study and were taught to navigate to videos on an iPhone(®) in history training. A multiple probe design across settings embedded in a multiple probe design across participants was used to evaluate the effects of PTD on initiation of self-instruction. All participants learned to self-instruct. Two participants generalized self-instruction to two novel settings. Two participants required instruction in two settings before generalizing to the third. Three participants generalized self-instruction in the presence of a task direction from the researcher to a task direction from their classroom teacher in all three settings. One participant generalized to a task direction presented by the classroom teacher in one setting, but not in the other two. All participants maintained self-instruction behaviors assessed 1 week after all participants met criteria in all settings. Self-instruction using videos or other supports on a mobile device is a pivotal skill and can increase independence for individuals with disabilities by decreasing a need for adult supports.
This study used a multiple probe across participants design to (a) evaluate the use of system of least prompts to teach students to self-instruct and (b) evaluate the use of a mobile device for a video activity schedule of a functional daily living skill. In baseline, the classroom teacher asked participants to make a snack and collected performance data. In the technology training condition, the teacher implemented a system of least prompts procedure to teach participants to initiate use of the mobile device, navigate to a training video activity schedule, pause/play videos of training tasks, and perform the modeled training tasks. After meeting criterion in technology training, the classroom teacher evaluated participant performance making a snack following use of a mobile device to self-instruct using a video activity schedule. Participant technology use was still assessed but not included in criterion. All four participants learned to independently initiate and navigate the mobile device during technology training. Three participants self-instructed using the video activity schedule to independently make a snack.
Young children with autism spectrum disorder (ASD) and related social-communication delays may display difficulties commenting on actions that occur in their natural environment. One method for increasing early conversation skills is direct instruction. Using video examples of actions may increase the salient features of instructional targets and, as such, may be an effective stimulus for presenting actions during instruction. The present study used a multiple-probe design across participants replicated across behaviors to evaluate the effectiveness of a 0- to 4-s progressive time-delay (PTD) procedure using video presentation of actions to teach three preschool-aged children with ASD and related social-communication delays to label actions. In addition, the teacher provided language expansion on all instructional targets, as well as assessed generalization to novel stimuli (videos and pictures or photographs). Results indicate that all participants acquired action labels. Two of the three participants generalized responses to novel videos and pictures while expanding their responses without direct instruction. Implications for teachers targeting action labels in early childhood settings are provided.
Numerous universities and colleges offer coursework approved by the Behavior Analyst Certification Board. Despite uniform requirements for approval, many differences exist among programs. To provide the field of behavior analysis with information about these differences, we conducted an initial analysis of programmatic variables and their relationship to pass rates on the Board Certified Behavior Analyst examination.Given the variety of preparation programs currently approved by the certification board, behavior analysts from different programs will likely differ with regard to their training and experiences.It is imperative that graduates from programs preparing behavior analysts are passing the examination to become board certified to fill specified jobs.Statistically significant variables associated with increased examination pass rates for programs include on-campus course delivery and accreditation by the Association for Behavior Analysis International.Variables lacking statistical significance with regard to impact on examination pass rates include the provision of supervision experience and the number of individuals from a program sitting for an exam.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
