We developed an Internet survey to identify treatments used by parents of children with autism. The survey listed 111 treatments and was distributed via colleagues and through chapters of the Autism Society of America and Autism Organizations Worldwide. A total of 552 parents submitted usable returns during the 3-month survey period. On average the parents(More)
A functional analysis examined the consequences that maintained episodic self-injury and the relationship between those consequences and otitis media for a child with moderate developmental disabilities. Results indicated that self-injury occurred only during periods of otitis media. Otitis media may have served as an establishing operation related to(More)
Eosinophils are recruited to sites of inflammation via the action of a number of chemical mediators, including PAF, leukotrienes, eotaxins, ECF-A and histamine. Although many of the cell-surface receptors for these mediators have been identified, histamine-driven chemotaxis has not been conclusively attributed to any of the three known histamine receptor(More)
This paper provides an overview of the literature dealing with the use of the Picture Exchange Communication System (PECS) and voice output communication aids (VOCAs) for promoting the performance of requests by students with developmental disabilities. Computerized and manual searches were carried out to identify the studies published during the last 15(More)
We developed a methodology, derived from the theoretical literatures on rule-governed behavior and private events, to experimentally investigate the relationship between covert verbal self-regulation and nonverbal behavior. The methodology was designed to assess whether (a) nonverbal behavior was under the control of covert rules and (b) verbal reports of(More)
OBJECTIVE To explore the types, prevalence and associated variables of cyberbullying among students with intellectual and developmental disability attending special education settings. METHODS Students (n = 114) with intellectual and developmental disability who were between 12-19 years of age completed a questionnaire containing questions related to(More)
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) intervention(More)
Functional analysis identified the consequences that maintained aggressive behavior and the relationship between these consequences and sleep deprivation for an individual with severe mental retardation. Results showed that aggression was maintained by negative reinforcement contingencies (escape from demand) and that aggression was more severe when sleep(More)
The present study assessed whether two children with multiple disabilities could learn to successfully operate a special microswitch through vocalization responses so as to obtain environmental stimulation. The study was carried out using a non-concurrent multiple baseline design across individuals. The treatment phase of the second child started after he(More)
Augmentative and alternative communication (AAC) includes picture exchange (PE) and speech-generating devices (SGD), but these two systems have rarely been compared. We therefore conducted three studies comparing PE and SGD for an adolescent boy with a developmental disability. Study 1 compared acquisition of a PE- and SGD-based requesting response and(More)
