This article summarizes research focusing on communication skills of people with intellectual and developmental disabilities (IDD) who communicate primarily without speech, sign language, or augmentative communication. Importantly, developmental theories were emphasized as useful for interpreting communication in children and adults. These studies…

Intraverbal tacts are an example of multiply controlled verbal behavior. More specifically, they are verbal responses under control of both a nonverbal (visual) stimulus (e.g., a green ball) and a verbal (auditory) stimulus (e.g., "What color?" vs. "What shape?"). Studies have shown that verbal behavior training can be arranged…

Background: The provision of unscheduled healthcare for children with intellectual disability is less researched than that focused on hospital settings or for adult services. The aim of the scoping review was to map the evidence base in this area and identify areas for future study. Method: A five-stage scoping review framework was adopted.…

The study focuses on the impact of the creative drama method on child sexual abuse (CSA) prevention program in Turkey. A pretest-posttest experimental design with a control group was used in the study. The research was carried out with a total of 72 preschool children aged 3-6 years. Data were collected by What If Situations Test (WIST). A…

Face perception is considered a remarkable visual ability in humans that is subject to a prolonged developmental trajectory. In response to the COVID-19 pandemic, mask-wearing has become mandatory for adults and children alike. Recent research shows that mask-wearing hinders face recognition abilities in adults, but it is unknown if the same holds…

Cognitive load theory's incorporation of evolutionary perspectives has generated several instructional designs based on movement, including the tracing effect, occurring when learners benefit from explicit instructions to trace out specific elements of lesson materials with the index finger. Historical descriptions of children's tracing behaviours…

Evidence was generated from a cross-section of 5,375 students who were completing primary education in 2014, as well as from their parents and school heads, across 309 primary schools located throughout Bangladesh, a South Asian country belonging to the global lower-middle-income category. Though the official duration of preschool education in…

With the knowledge that deaf children benefit from early exposure to signed language, questions are raised about the role of specific types of language input that are beneficial in early childhood classrooms. This quasi-experimental study explores the effects of ASL rhyme, rhythm, and handshape awareness activities on 4- to 6-year-old deaf…

It is important for children to learn safety skills, especially involving dangerous stimuli such as medicine that can be found in almost every household. This study examined a generalization-enhanced behavioral skills training package to teach children with autism poison safety skills. Three children ages 4- to 10-years-old received generalization…

This systematic review investigated the effectiveness of acceptance and commitment therapy for the parents of children with autism spectrum disorder. PsychInfo, CINAHL, PubMed, Science Direct, and Psychology and Behavioral Sciences Collection were searched using the terms "acceptance and commitment", "autism" and…

Recent research has shown that a religious upbringing renders children receptive to ordinarily impossible outcomes, but the underlying mechanism for this effect remains unclear. Exposure to religious teachings might alter children's basic understanding of causality. Alternatively, religious exposure might only affect children's religious…

Globally, there are more bilingual speakers than monolingual speakers; however, scant research evidence exists regarding social communication development and outcomes for bilingual children with autism spectrum disorder (ASD). A stronger evidence base will facilitate health professionals and educators providing accurate recommendations regarding…

Background: This systematic review aimed to explore the effects of sport and physical activity on behaviour and emotional problems, mental health and psychosocial well-being of children and adolescents with intellectual disability. Method: Five databases were searched systematically (ERIC, MEDLINE, PsycINFO, SportDISCUS and SCOPUS), up to 28…

This study investigated the systematic rise in cognitive ability scores over generations, known as the "Flynn Effect," across middle childhood and early adolescence (7-15 years; 291 monozygotic pairs, 298 dizygotic pairs; 89% White). Leveraging the unique structure of the Louisville Twin Study (longitudinal data collected continuously…

We explored the causal role of individual and age-related differences in working memory (WM) capacity in long-term memory (LTM) retrieval. Our sample of 160 participants included 120 children (6-13-years old) and 40 young adults (18-24 years). Participants performed a WM task with images of unique everyday items, presented at varying set sizes.…
