Individuals with developmental disabilities often do not develop vocal repertoires, thus requiring the use of augmentative devices. Teaching caregivers to conduct communication training with their children may be one way to foster communication with their device in the natural environment. This study replicates Rosales, Stone and Rehfeldt (2009),…

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…

In the current investigation, we reviewed the literature on mand training for individuals with intellectual and developmental disabilities (IDD) in schools. Ninety-three studies met our inclusion criteria including 225 individual participants. Data were extracted related to participant demographics (e.g., age, disability, response form) and study…

A primary goal of behavioral interventions is to reduce dangerous or inappropriate behavior and to generalize treatment effects across various settings. However, there is a lack of research evaluating generalization of treatment effects while individuals with functionally equivalent problem behavior interact with each other. For the current study,…

With the number of students with autism and related developmental disabilities increasing and a lack of trained professionals, solutions are needed to provide training on a large scale. Alternative training approaches need to be developed so that paraprofessionals can access training in an efficient and effective way. One such possibility is…

Although experimental analysis methodologies have been useful for identifying the function of a wide variety of target behaviors (e.g., Iwata, Dorsey, Slifer, Bauman, & Richman, 1982/1994), only recently have such procedures been applied to verbal operants (Lerman et al., 2005). In the current study, we conducted a systematic replication of the…

By watching and responding to the way a shill answered "yes-no" questions about food items, a developmentally delayed preschool boy greatly improved over his poor base-line "yes-no" answers to these same items. He was also able to give correct answers subsequently during generalization probe sessions. (PS)

Two boys, ages 7 and 9, with severe developmental disabilities were taught to use requests conditionally (when desired items were proximally distant) to obtain desired snack items. Results suggest that the conditioned discriminations were established quickly and both learners generalized their conditional discriminations to other contexts.…
