The purpose of the study was to experimentally model summation in convergent multiple control over selection-based verbal behavior. Eight undergraduate students participated. In divergent--convergent tact training, a three-choice match-to-sample task was used to establish two selection-based tacts for each of five pictorial stimuli. One textual…

Deficits in communicating one's wants and needs can have significant and detrimental effects on quality of life. Particularly for individuals with autism spectrum disorder (ASD) and other related disabilities, manding is a pivotal skill that influences long-term prognosis. Mand training is complex and relies on several components to facilitate…

Functional communication training (FCT; Carr & Durand, 1985) is frequently utilized as a treatment for socially maintained problem behavior (Tiger et al., 2008). Although FCT is a viable treatment option for the reduction of problem behavior, researchers have identified several variables related to the selection of the functional communication…

Abrupt discontinuation of functional communication training can cause resurgence of challenging behavior. Teaching multiple alternative responses in sequence ("serial training") may reduce resurgence, relative to teaching a single alternative. However, previous evaluations of serial training included a different number of response…

Due to the increasing number of students in need of special education services and the shortages of licensed special education personnel, paraeducators have become critical in the education of students diagnosed with autism spectrum disorder and other disabilities in school settings. As a result, the training of paraeducators has become a major…

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),…

Most verbal behavior curricula for children with autism spectrum disorder (ASD) focus on teaching multiple mands during the early stages of training (e.g., picture exchange communication system; Bondy & Frost, 1994). However, few, if any, of those curricula train children with ASD to differentially mand only for reinforcers that are reasonable…

Generalization is a critical outcome for individuals with autism spectrum disorder (ASD) who display new skills in a limited range of contexts. In the absence of proper planning, generalization may not be observed. The purpose of the current study was to directly compare serial to concurrent multiple exemplar training using total training time per…

Young children with autism may fail to mand using a range of frames (e.g., "I want," "May I have," "Please give me"). We examined the effects of simultaneous script training and script fading on acquisition and maintenance of varied mand frames with six preschool children with autism. For participants who did not…

This study investigated the effects of tact prompts on the acquisition and retention of divergent intraverbal responding to categorical questions involving conditional discriminations. A 6-year-old boy with autism participated in the study. A multiple probe design across behaviors was used. A tact-prompt procedure was implemented. The results…

Recently, there has been a proliferation of research on the functional independence of two of Skinner's (1957) verbal operants, the mand, and the tact. This research has produced highly variable results. In this article, we provide a critical review of the literature on mand-tact independence, a literature that has implications for both theory and…

Five reinforcing activities were presented to and interrupted for two participants with autism. An errorless teaching procedure was then introduced with two similar activities prompting the participants to request information saying "How?" in order to resume the activity. The dependent variable included both the cumulative number of…

In resurgence, an operant behavior that has undergone extinction can return ("resurge") when a second operant that has replaced it itself undergoes extinction. The phenomenon may provide insight into relapse that may occur after incentive or contingency management therapies in humans. Three experiments with rats examined the impact of several…

Millions of Americans are diagnosed with dementia, and that number is only expected to rise. The diagnosis of dementia comes with impairments, especially in language. Furthermore, dementia-related functional declines appear to be moderated by environmental variables (Alzheimer's Association, "Alzheimer's & Dementia: The Journal of the…

An equivalence class is typically established when a subject is taught a set of interrelated conditional discriminations with physically unrelated stimuli and additional, untaught, conditional discriminations are then demonstrated. Interestingly, and perhaps counter-intuitively, the relations among the stimuli within such a class are not…
