The purpose of the current study was to explore the scientific utility of two behavior analytic assessments (i.e., progressive ratio and demand assessments) for psychotropic medication evaluation. For a sample of 23 children with disabilities who were prescribed medication, we conducted a series of generalizability and optimization studies to…

Although autism spectrum disorder (ASD) is a heterogeneous disorder, recently more homogeneous phenotypic subgroups, which still lack evidence, have been identified. Our goal is to describe and analyse different behavioural profiles of ASD, in social communication and interaction (SCI) and restricted and repetitive behaviours and interests…

Previous research shows that children evaluate the competence of others based on how effectively someone accomplished a goal, that is, based on the observed outcome of an action (e.g., number of attempts needed). Here, we investigate whether 5- to 10-year-old children and adults infer competence from how efficiently someone solves a task by…

Challenging behaviour is a problematic issue for students with intellectual disability, including those in special education settings. While there is a need to address challenging behaviour in these schools, most Vietnamese classroom teachers struggle to deal with those behaviours due to their lack of effective strategies. In response, this first…

As a treatment for escape-maintained problem behavior, differential reinforcement of alternative behavior (DRA) is typically initiated by reinforcing compliance on a dense reinforcement schedule. This work schedule is then progressively thinned such that the individual is required to complete more work, up to some socially acceptable terminal…

Children with autism spectrum disorder often display some form of challenging behavior and have complex communication needs. Functional communication training is an evidence-based practice that (a) decreases challenging behavior and (b) increases appropriate communicative behavior. Recent research has demonstrated how using augmentative and…

Background: To document whether the sociocognitive peculiarities of people with Down Syndrome impact the construction of attachment at different ages, a systematic review of the literature was carried out. Method: This review followed the Preferred Reporting Items for Systematic Reviews and MetaAnalyses, was conducted on three databases: psycINFO,…

Past research suggests that children, particularly those with autism spectrum disorder, with general behavioral inflexibility to objects, persons, and environments may be at risk for feeding problems. However, questions remain about whether feeding problems are better predicted by behavioral inflexibility or sensory sensitivity, and whether…

The present study describes how deaf and hard-of-hearing (d/hh) children who primarily use listening/spoken English (oral d/hh) solve one-step arithmetic story problems. Past research examined the story problem-solving of hearing children (Carpenter et al., 2015) and d/hh children who used age-appropriate American Sign Language (signing d/hh;…

This dissertation was designed to determine which behavior analytic intervention was more effective in the treatment and reduction of mouthing non-nutritive substances in children diagnosed with autism. This study included four participants in an A-B-A reversal design with a component analysis across four intervention phases. The study…

Children with developmental delay (DD) are at increased risk for behavioral difficulties. Past research has indicated that behavioral problems can interact with other parental difficulties in families of children with DD. To date, no research has explored the moderating role of marital satisfaction in the relationship between child behavioral…

Single-subject research can provide adequate justification when developing successful evidence-based educational practices for children with autism spectrum disorder (ASD), which can help such students thrive academically. This research investigates whether point-of-view video modelling effectively improved the word problem-solving addition…

Given that autistic children are hospitalized at higher rates than neurotypical peers, it is important to understand the autism-specific preparedness of healthcare providers. Certified Child Life Specialists (CCLSs) play a crucial role in pediatric hospitalizations by providing socioemotional support and coping strategies. The present study…

Autism spectrum disorders (ASD) are neurodevelopmental disorders characterized by difficulties in communication and social-emotional interaction. It is associated with an increase of parental stress and poor family functioning, both of which are harmful for a child's functioning and adaptive behavior. An important source of support to parents are…

Studies have shown that there are differences between the presentations of males and females diagnosed with autism. There remains a developing understanding about how the presentation of autism differs between boys (hereafter referred to as 'assigned males at birth') and girls (assigned females at birth). This study sought to investigate the…
