This study aimed to teach individuals with autism spectrum disorder (ASD) and limited vocal speech to emit target vocalizations while using a speech-generating device (SGD). Of the 4 participants, 3 began emitting vocal word approximations with SGD responses after vocal instructional methods (delays, differential reinforcement, prompting) were…

We evaluated an intervention aimed at teaching two adolescents with autism spectrum disorders (ASDs) to name pictures using speech-generating devices (SGDs). The effects of intervention were evaluated in two studies using multiple-probe across participants designs. Intervention--consisting of time delay, least-to-most prompting, and differential…

We assessed the maintenance of newly acquired mands under presession reinforcer access (reinforcer efficacy abolished) and no presession reinforcer access (reinforcer efficacy established) conditions with 3 children with autism spectrum disorder. Results suggested that the no presession access condition established the value of the reinforcer and…

The current study examined the effects of motivating operations on problem behavior and academic engagement for 2 students with autism. Classroom sessions were preceded by periods in which the participants had access or no access to the items functionally related to their problem behavior. Results suggested that presession access may result in…

We evaluated a program for teaching two adolescents with autism spectrum disorders (ASD) to perform more advanced operations on an iPod-based speech-generating device (SGD). The effects of the teaching program were evaluated in a multiprobe multiple baseline across participants design that included two intervention phases. The first intervention…

We conducted a systematic analysis of studies that involved the treatment of rumination and operant vomiting in individuals with developmental disabilities. A total of 21 studies involving a combined 32 participants were identified and analyzed in terms of (a) participant characteristics, (b) dependent variables, (c) intervention procedures, (d)…

We evaluated the effects of presession satiation on challenging behavior and academic engagement during subsequent classroom activities for three 5-6 year-old children with autism. The percentage of 10-s intervals with challenging behavior and academic engagement during 20-min classroom activity sessions was observed under two conditions. One…

An alternating treatments design compared one condition in which a child with autism was allowed to engage in stereotypy freely prior to the intervention (abolishing operation component) to a second condition without the free-access period. Levels of stereotypy and problem behavior were lower and levels of functional play were higher in the…

Skin-picking is a type of self-injurious behavior involving the pulling, scratching, lancing, digging, or gouging of one's own body. It is associated with social impairment, and increased medical and mental health concerns. While there are several reports showing that skin-picking is common in individuals with developmental disabilities, knowledge…

We used widely available videoconferencing equipment to support teachers to conduct preference assessments for three students with autism and developmental disabilities. Supervisors located at a university used videoconferencing equipment to collect data on students' choice of items, the fidelity of teacher implementation of the assessment…

Play is widely acknowledged to be an integral part of human development and children with autism often experience substantial delays in the development of play behaviors. This review updates older reviews by covering the last 10 years of research targeting functional and symbolic play in children with autism. The review differs from other reviews…

We examined the behavior-altering effect of the motivating operation on challenging behavior during leisure activities for three individuals with severe disabilities. Prior functional analyses indicated that challenging behavior was maintained by positive reinforcement in the form of attention or tangible items for all participants. During leisure…

We reviewed studies involving the treatment of elopement in individuals with developmental disabilities. Systematic searches of three electronic databases, journals, and reference lists identified 10 studies meeting the inclusion criteria. These studies were evaluated in terms of: (a) participants, (b) procedures used to assess elopement, (c)…
