We assessed whether novel praise statements could be used to (a) maintain and increase responses with existing reinforcement histories and (b) teach a previously untaught response among children diagnosed with autism spectrum disorder across two experiments. During response-stimulus pairing, two responses resulted in preferred edibles but only one…

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…

Prompts are commonly used during discrete trial teaching for individuals diagnosed with autism spectrum disorder (ASD). Three commonly used prompting systems include constant time delay, most-to-least prompting, and flexible prompt fading. Most of the research demonstrating the effectiveness of these three prompting strategies have been completed…

The go/no-go with compound stimuli is an alternative to matching-to-sample to produce conditional and emergent relations in adults. The aim of this study was to evaluate the effectiveness of this procedure with two children diagnosed with autism. We trained and tested participants to respond to conditional relations among arbitrary stimuli using…

Many individuals with autism spectrum disorders (ASD) display stimulus overselectivity, wherein a subset of relevant components in a compound stimulus controls responding, which impairs discrimination learning. The original experimental research on stimulus overselectivity in ASD was conducted several decades ago; however, interventions for…

Reciprocal conversations, instructional activities, and other social interactions are replete with multiply controlled intraverbals, examples of which have been conceptualized in terms of conditional discriminations. Although the acquisition of conditional discriminations has been examined extensively in the behavior-analytic literature, little…

The present investigation evaluated the effectiveness of category tact and match-to-sample instruction in facilitating the emergence of intraverbal responses (i.e., naming several items belonging to a specific category) for 2 children with autism. Results demonstrated the emergence of untaught responses, suggesting an effective instructional…

We examined a procedure consisting of a preference assessment, prompting, contrived conditioned establishing operations, and consequences for correct and incorrect responses for teaching children with autism to mand "which?" We used a modified multiple baseline design across 3 participants. All the children learned to mand "which?" Generalization…

Children with autism often demonstrate less variable behavior than their typically developing peers and those with other cognitive disabilities. A possible reason for lack of response variability emitted by children with autism is that they do not have a variety of response forms in their repertoire. Multiple-exemplar training through the use of…

Pigeons were exposed to a repeated acquisition procedure in which no delays were imposed and rate of responding was relatively high. They also were exposed to conditions in which delays were arranged between trials within chains or between completed chains, and rates of responding were lower. Number of trials, rate of reinforcement, difficulty of…

We tested the effects of an observational intervention (Greer & Singer-Dudek, 2008) on establishing children's books as conditioned reinforcers using a delayed multiple baseline design. Three preschool students with mild language and developmental delays served as the participants. Prior to the intervention, books did not function as reinforcers…

Top-ranked items were identified during 30-min free-operant preference assessments for 9 individuals. Data from each session were analyzed to identify the item (a) that was engaged with first in each session and (b) to which the most responding was allocated after 5 min, 10 min, 15 min, 20 min, and 25 min had elapsed in each session. The results…

Examination of responding under various schedule arrangements is a core component of many analyses of operant behavior. Much of the pioneering work in applied behavior analysis was bred from laboratory research involving the exposure of nonhuman subjects to a variety of schedule arrangements. Hodos (1961) described a schedule arrangement in which…

In the type of intraverbal that consists of saying the opposite of a word, two intraverbals are related to one another because the response form of each intraverbal functions as part of a discriminative stimulus for the other (e.g., "cold" in response to "name the opposite of hot," and vice versa). Moreover, the contextual cue "Name the opposite…

A sequence of behaviors consisting of appropriate responses, inappropriate responses, or a combination of both can be linked together in a behavior chain. Several operant processes may disrupt behavior chains. For example, one or more members of the behavior chain may be affected when reinforcement is withheld for the last response in the chain…
