A competing stimulus assessment is used to identify stimuli that are associated with a low level of challenging behavior and a high level of engagement. These stimuli are often used as a treatment component for challenging behavior that is maintained by automatic reinforcement. One limitation of implementing competing stimulus assessments is that…

Recommendations for achieving generalized instructional outcomes often overlook the capacity for generative learning for most verbally competent humans. Four children (ages 5-8) participated in this project. In Study 1, we provided decontextualized discrete trial teaching to establish arbitrary relations between colors, pictures of characters, and…

Previous researchers found that individuals with intellectual and developmental disabilities tend to prefer edible over leisure stimuli, although leisure stimuli may still function as reinforcers. We replicated and extended previous research in a 2-part experiment with typically developing children. In Experiment 1, we evaluated 15 children's…

Teaching toilet training skills to children with autism spectrum disorder (ASD) can be challenging. Many techniques use Azrin and Foxx's Rapid Toilet Training method (RTT). However, some children with ASD find the first RTT step of entering the bathroom or restroom to be challenging due to the relatively loud sound of the toilet flushing. Although…

Functional communication training (FCT) is an effective intervention for teaching communication responses and reducing challenging behavior. One limitation of FCT is that frequent reinforcement may be impractical or impossible in many situations. Recently, Mitteer et al. published a tutorial in the journal "AAC" that provided video…

In signaled active avoidance (SigAA), rats learn to suppress Pavlovian freezing and emit actions to remove threats and prevent footshocks. SigAA is critical for understanding aversively motivated instrumental behavior and anxiety-related active coping. However, with standard protocols ~25% of rats exhibit high freezing and poor avoidance. This has…

The world often goes too fast for children with autism spectrum disorder (ASD) to process. We tested the therapeutic effectiveness of input slowing in children with ASD. Over 12 months, 12 children with ASD had weekly speech therapy sessions where stimuli were slowly played on a PC, while 11 age- and level-matched children with ASD had speech…

The main purpose of this study was to systematically review and meta-analyse the single-case studies on the use of activity schedules with individuals with autism spectrum disorders. The other purposes were to describe the characteristics of activity schedule studies, assess the design standards of activity schedule studies, estimate the treatment…

The participant was a boy diagnosed with autism spectrum disorder (ASD) who displayed severe food selectivity, which raised concerns about imbalanced nutrient consumption. The intervention used combined stimulus fading with simultaneous stimulus presentation without escape extinction (EE) and was implemented by teachers in a school setting. In…

Individuals with intellectual and developmental disabilities have increased risk for developing challenging behavior. One particularly dangerous topography of challenging behavior is rapid eating. Rapid eating can lead to increased risk for choking and obesity as well as negatively impact social interactions during mealtimes (Anglesea et al.,…

Background: People with severe-to-profound intellectual disabilities often lack meaningful interactions with others. Communication partners need to be skilled in identifying and responding to often-subtle behaviours. One method of facilitating interaction is the use of sensory-based stimuli. Method: This study measured the impact of sensory-based…

This triple-arm, double-blind, randomized clinical trial investigated the effect of multisession prefrontal transcranial direct current stimulation (tDCS) on social functioning in individuals with autism spectrum disorder (ASD). A total of 105 individuals (age 14-21 years) diagnosed with ASD were randomized into the active-tDCS, sham-tDCS, and…

Persons with Autism Spectrum Disorder (ASD) and low cognitive functioning tend to demonstrate regulatory responses to auditory sensations, leading to disturbed behaviours such as self-stimulation, stereotypical movements, even aggression and self-harm. The aim of this study was to investigate whether listening to specific sounds and music reduced…

The use of auditory stimulation to decrease vocal stereotypy in individuals with autism spectrum disorder has been the focus of several studies in recent years. Some of these studies investigated the use of auditory stimulation in the form of music, some evaluated the use of other interventions in tandem with auditory stimulation, and others…

Counterconditioning (CC) is a form of retroactive interference that inhibits expression of learned behavior. But similar to extinction, CC can be a fairly weak and impermanent form of interference, and the original behavior is prone to relapse. Research on CC is limited, especially in humans, but prior studies suggest it is more effective than…
