Cognitive flexibility refers to various processes which enable behaviors to be modified on the basis of a change in the contingencies between stimuli or responses and their associated outcomes. Reversal learning is a form of cognitive flexibility which measures the ability to adjust responding based on a switch in the stimulus--outcome…

We used a contingent acoustical feedback procedure to increase appropriate walking and decrease toe walking exhibited by a young boy with autism. After a pre-treatment screening assessment suggested that toe walking was maintained by automatic reinforcement, we paired an auditory stimulus (i.e., a clicking sound) with access to a preferred item to…

When discrete localizable stimuli are used during appetitive Pavlovian conditioning, "sign-tracking" and "goal-tracking" responses emerge. Sign-tracking is observed when conditioned responding is directed toward the CS, whereas goal-tracking manifests as responding directed to the site of expected reward delivery. These…

The provision of reinforcement to increase desired behaviors is a crucial element of behavior analytic intervention for individuals diagnosed with autism spectrum disorder (ASD). Formal preference assessments, like the multiple stimulus without replacement procedure (MSWO), are often used to determine reinforcers used during intervention. While…

The most researched and effective practice for instructing children with Autism Spectrum Disorder (ASD) is applied behavior analysis (ABA; Baer, Wolf, & Risley, 1968; Reichow, 2012; Smith & Eikeseth, 2011; Virués-Ortega, 2010). ABA is a scientific approach to systematic instruction, data collection, and data analysis based on observable…

Successful conversation requires that the speaker's behavior is sensitive to nonvocal listener responses. We observed children with autism spectrum disorder during conversation probes in which a listener periodically displayed nonvocal cues that she was uninterested in the conversation. We used behavioral skills training to teach conversation…

Background: Previous studies of anger management in people with intellectual disability failed to control for the effects of the number of provocative stimuli presented and lacked direct measures of behaviour and treatment integrity data. Methods: This experiment systematically assessed and presented discriminative stimuli for aggressive…

Special education professionals and teachers of students with autism face many behavioral and instructional challenges. In addition to teaching content to a demanding population, teachers are often faced with particular circumscribed and special interests that often take up time and divert attention from the students. It is an educators job to…

This investigation evaluated the use of conditional discrimination (CD) instruction and multiple exemplar instruction (MEI) to establish derived relational responding in accordance with hierarchical frames with school aged children. The first experiment used a multiple probe design to evaluate the effectiveness of MEI to teach participants to…

Autism is currently one of the most prominent and widely discussed human conditions. Its increased prevalence has intensified the demand for effective educational and therapeutic services, and intervention science is providing mounting evidence about practices that positively impact outcomes. The purpose of this report is to describe a set of…

As they learn to negotiate social expectations, children test limits, get carried away, forget, and make mistakes. In fact, having these experiences--and seeing how adults respond to them--is one way children learn about how to behave. Just as when they teach academics, teachers can use students' behavioral mistakes as opportunities for learning.…

The delivery of food contingent on 10 s of consecutive toy engagement resulted in a decrease in engagement and a corresponding increase in other responses that had been previously reinforced with food. Similar effects were not observed when tokens exchangeable for the same food were delivered, suggesting that engagement was disrupted by the…

Evidence-based practices (EBPs) are the basis on which teachers and other service providers are required to design educational programs for learners with autism spectrum disorders (ASD). As part of their work with the National Professional Development Center (NPDC) on ASD, researchers developed a process for reviewing the research literature and…

Using a two-way signaled active avoidance (2-AA) learning procedure, where rats were trained in a shuttle box to avoid a footshock signaled by an auditory stimulus, we tested the contributions of the lateral (LA), basal (B), and central (CE) nuclei of the amygdala to the expression of instrumental active avoidance conditioned responses (CRs).…

Stimuli associated with primary reinforcers appear themselves to acquire the capacity to strengthen behavior. This paper reviews research on the strengthening effects of conditioned reinforcers within the context of contemporary quantitative choice theories and behavioral momentum theory. Based partially on the finding that variations in…
