Various types of augmentative and alternative communication systems have been successfully used to enable functional communication in children with developmental disabilities. The effects of such systems on natural speech production have also been investigated, but few studies have explored the effects of specific procedures aim at inducing…

Lag reinforcement schedules have been shown in previous research to be an effective intervention for teaching verbal and nonverbal response variability to individuals with developmental disabilities. In more recent research, variability itself has been considered a reinforceable behavior in its own right (Susa & Schlinger, The Analysis of…

The ability to engage in positive social interactions is an important goal for young children with developmental disabilities (DDs). Peer-mediated intervention (PMI), one category of interventions often employed with those who show social skill deficits, involves use of typical peers who live model appropriate behaviors. A second frequent category…

Background: This investigation details procedures used to teach enhanced natural gestures (ENGs) and illustrates its use with three students with Angelman syndrome (AS). Materials and Methods: Themes were extracted, using a process of content analysis, to organize individuals' feedback pertaining to previous versions of the instructional…

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…

Research Findings: The objective of this research was to evaluate the effectiveness of Incredible Years Basic Parent Training (IYPT Basic) in a community clinic setting in Hong Kong. IYPT Basic is a Western program developed to promote children's academic, social, and emotional regulation skills and to reduce conduct problems among typically…

This study examined the effectiveness, generalization, and maintenance of a multi-element intervention consisting of brief direct instruction social skill lessons, a prompting procedure, and a fading procedure to promote social engagement in an integrated lunchroom and playground setting for three elementary age students with developmental…

Students with autism spectrum disorders (ASD) have difficulties with verbal language. Many interventions to remediate such deficits require numerous materials and significant teacher time. This study sought to determine if a simple multi-component intervention that incorporated noncontingent reinforcement (NCR) and verbal modeling would result in…

There is growing interest in the role that physical illness and pain might play in exacerbating problem behavior in individuals with developmental disabilities. Assessment of these factors, however, is often difficult since many individuals have minimal verbal communication skills. In response to this difficulty, we developed a sequential method…

As part of the Combating Autism Act of 2006, the members of the Interagency Autism Coordinating Committee (IACC) are required to develop an annual "Summary of Advances" to describe each year's top advances in autism spectrum disorder (ASD) research. These advances represent significant progress in the early diagnosis of ASD, understanding the…

The Verbal Interaction Analysis System is presented as an assessment of initial, dyadic conversations. Application of the VIAS to two case studies featuring mildly to moderately intellectually disabled adults shows how the VIAS provides an index of competence and assists in the development of specific treatment strategies.

Discusses the effects of a cognitive-behavioral intervention that focused on facilitating expressive behaviors with their parents of 44 children (ages 22-32 months) with pervasive developmental delays and autism. Results found the program "Learning to Speak" increased the children's verbal compliance and decreased acts of verbal noncompliance. (CR)
