PARENT-IMPLEMENTED SCRIPT FADING TO PROMOTE PLAY-BASED VERBAL INITIATIONS IN CHILDREN WITH AUTISM

We trained 3 mothers of children with autism to create, implement, and systematically fade scripts to promote vocal initiations during play. All 3 childrens scripted and unscripted initiations increased after the introduction and fading of scripts, and unscripted initiations were maintained at the 2-week follow-up. The results indicate that parents of children with autism can successfully implement script-fading procedures in their homes and that these procedures are effective methods to increase vocal initiations during play.

SCRIPT FADING TO PROMOTE UNSCRIPTED BIDS FOR JOINT ATTENTION IN CHILDREN WITH AUTISM

We used a script-fading procedure to teach 3 children with autism to initiate bids for joint attention. We examined the effects of (a) scripts, (b) varied adult scripted responses, and (c) multiple-exemplar script training on promoting unscripted language during bids for joint attention. All 3 participants learned to initiate bids for joint attention, and the response generalized to untrained stimuli, conversation partners, and the classroom environment.

The Effects of Video Modeling on Staff Implementation of a Problem-Solving Intervention with Adults with Developmental Disabilities.

We investigated the effects of video modeling on the percentage of correctly implemented problem-solving steps by staff in a group home for adults with developmental disabilities, using a nonconcurrent multiple baseline design across participants. The treatment consisted of staff watching a video model demonstrating the correct implementation of a problem-solving intervention (i.e., teaching clients to identify problems, possible solutions, and consequences to each solution, and to choose the best solution). The percentage of correctly implemented problem-solving steps increased for all participants, and the effect was maintained over time, generalized to novel problems, and generalized from role play with a researcher to actual clients.

Technology-MediatedConsultation to Assist Rural Students: A Case Study

Emerging videoconferencing technologies permit face to face communication in a virtual, real time manner so that educational expertise can be shared across geographical boundaries. Although demonstrations of successful use of videoconferencing to share expertise of teachers and related service personnel go back 20 years, the sustained use of technology for this purpose has yet to occur. This paper describes a case study in which consultation was delivered to a special education classroom in a remote region to help develop and implement the IEP for a young child with autism. While there was a clear benefit to the child in this case, collateral technological and programmatic challenges were never fully overcome, thus shortcutting the intended intervention. Issues that must be resolved for families and local education agency personnel to benefit from the expertise of consultants at a distance are discussed.

Using Video InstructionProcedures with and without Embedded Text to Teach Object Labeling to Preschoolerswith Autism: A Preliminary Investigation

Three preschoolers diagnosed with autism were taught how to expressively label common food items using video instruction with and without embedded text. Twenty unknown stimuli were randomly assigned to either the embedded text or no-embedded text condition. Using a commercially available video editing program, a DVD was created that presented test stimuli (photographs of food items) with the auditory instruction: “What is it?” followed by the auditory presentation of the name of the stimulus. Stimuli in the embedded text condition also included the typed name of the item below the picture. All instruction was presented via a DVD player and viewed on a 19-inch television. Probe sessions were conducted after teaching sessions via the DVD player to assess correct responses. While the impact of including embedded text was somewhat unclear, all participants acquired expressive object labeling skills by watching the DVD.

The use of linked activity schedules to teach children with autism to play hide-and-seek

Linked activity schedules were used to establish appropriate game play in children with autism during a game of hide-and-seek. All 6 participants demonstrated acquisition of appropriate play skills in the presence of the activity schedules and maintained responding during subsequent phases. When the schedules were removed, responding decreased to baseline levels, demonstrating that the schedules controlled responding. Implications for future research on the use of activity schedules to teach social behavior are discussed.

PRELIMINARY INVESTIGATION OF A VIDEO-BASED STIMULUS PREFERENCE ASSESSMENT

Video clips may be an effective format for presenting complex stimuli in preference assessments. In this preliminary study, we evaluated the correspondence between preference hierarchies generated from preference assessments that included either toys or videos of the toys. The top-ranked item corresponded in both assessments for 5 of the 6 participants, and the top- and bottom-ranked items corresponded for 4 participants. The implications of these results for future research on video preference assessments are discussed.

Response Competition and Stimulus Preference in the Treatment of Automatically Reinforced Behavior: A Comparison.

Clinicians are particularly challenged by the development of interventions for behavior maintained by automatic reinforcement because reinforcers that maintain the responses often cannot be directly observed or manipulated. Researchers have conducted either preference assessments or competing items assessments when developing effective treatments for behavior maintained by automatic reinforcement. However, interventions based on these assessments have not been directly compared. The current study evaluated procedures to make such a comparison. High-competition items resulted in greater reductions in vocal stereotypy than did high-preference items for a preschool boy with autism.

Teaching and maintaining ethical behavior in a professional organization.

In addition to continuing education mandates by the Behavior Analyst Certification Board (BACB), behavior-analytic professional organizations may adopt systems that teach and maintain ethical behavior in its employees. Systems of ethical supervision and management may allow for an organization to customize training that prevents ethical misconduct by employees. These systems may also allow supervisors to identify ethical problems in their infancy, allowing the organization to mitigate concerns before they further develop. Systems of ethical management and supervision also may help to improve services and promote consumer protection. Additional benefits might include both avoiding litigation and loss of consumers and income. These systems may promote the field of Behavior Analysis as a desirable, consumer-friendly approach to solving socially significant behavior problems.

The use of a discrimination‐training procedure to teach mand variability to children with autism

We investigated the effects of a script-fading and discrimination-training procedure on mand variability in preschoolers with autism. Participants were taught to vary their vocal mands in the presence of written scripts, a green placemat, and a lag schedule of reinforcement. They were also taught to engage in repetitive mands in the presence of the same written scripts and a red placemat. When the scripts were removed, all 3 participants continued to engage in varied manding in the presence of the green placemat and lag schedule, and they continued to engage in repetitive manding in the presence of the red placemat. When the lag schedule was also removed, 2 of the 3 participants continued to engage in varied responding in the presence of the green placemat and repetitive responding in the presence of the red placemat. Finally, all 3 participants demonstrated generalization and maintenance of mand variability during snack sessions with their peers.
