This applied dissertation was designed to better understand the experience of having a sibling with autism spectrum disorder (ASD). Research has historically focused primarily on parents of individuals with ASD and their perceptions of how siblings were impacted; however, there was a lack of adequate research where information was obtained from…

The objectives of this study were to characterize the bibliometric indicators of scientific productivity on adaptive behavior (AB) in children and adolescents with autism spectrum disorders (ASD) during the year 2021. The PubMed database was used to summarize information from quantitative scientific articles (cross-sectional, longitudinal and…

Background & Aims: Discourse markers, such as "well" or "like," serve a variety of functions to support conversational reciprocity: filling pauses, aiding word-finding, and modulating turn-taking by holding the conversational floor. Previous research shows that autistic individuals use discourse markers less frequently than…

Competing viewpoints on the independency or interdependency of Skinner's verbal operants have been discussed in the literature and with empirical support for both positions generated using single-case research methods. Our study provides support for the interdependency of the verbal operants using items contained in the Verbal Behavior Milestones…

Children with autism spectrum disorder (ASD) engage in reduced levels of physical activity relative to neurotypical children. Researchers conducted 2 studies to (1) evaluate the influence of the number of physical activity options and effort on choice and (2) develop a token-based intervention to increase physical activity engagement and evaluate…

Autism spectrum disorders (ASDs) are a group of neurodevelopmental-related disorders with a high genetic risk. Recently, chromatin remodeling factors have been found to be related to ASDs. "SMARCA4" is such a catalytic subunit of the chromatin-remodeling complex. In this report, we identified seven novel missense variants in the…

Proponents of autism intervention and those of the neurodiversity movement often appear at odds, the former advocating for intensive treatments and the latter arguing that autism must be accepted as a form of diversity. The history of behavioral intervention has understandably outraged many in the Autistic community, though many still value…

The Behavioral Inflexibility Scale (BIS) is a recently developed measure of behavioral inflexibility, defined as rigid patterns of behavior that contrast with the need to be flexible when the situation calls for it. In this study, we sought to replicate previous findings on the psychometric properties of the BIS in a community sample. Data for…

Investigations into the etiology of autism spectrum disorders have been largely confined to two realms: variations in DNA sequence and somatic developmental exposures. Here we suggest a third route--disruption of the germline epigenome induced by exogenous toxicants during a parent's gamete development. Similar to cases of germline mutation, these…

Some studies report delayed theory of mind (ToM) development in children with specific language impairment (SLI), while others do not. A ToM delay is acknowledged in children with autism spectrum disorder (ASD), while whether these children also display a deficit is still under debate. In the current study, we drew on a developmental trajectory…

As autism is an invisible and often stigmatised condition, disclosing the diagnosis may lead to both support and/or discrimination. This mixed-methods questionnaire study examined autistic adults' experiences of disclosure in various contexts. The sample consisted of 393 participants aged 17-83 years from two longitudinal surveys. Almost all…

Autistic children tend to show divergent social information processing, and controversies exist regarding the mechanisms underlying this processing. In this article, we summarize and categorize the current theories and evidence related to hypo- and hyperarousal accounts of social information processing in autism. The hypo-arousal account proposes…

The stressors autistic individuals encounter and experience as traumatic may vary from non-autistics. We conducted a qualitative study to identify potential sources of trauma for autistic individuals and evaluate correspondence with a standard measure. We enrolled autistic adults (N = 14) and caregivers (N= 15) with varied adversities, levels of…

A common misperception of people with disabilities is that they are unable and/or disinterested in sex; however, research indicates that they express sexual desires and engage in sexual behaviors. Studies about the sexuality of people on the Autism Spectrum (ASD; on the spectrum), however, suggests they receive limited sex education and are more…

Recent high school graduates enter a period of postsecondary transition where they are expected to obtain employment, enter college, or enroll in a training program. Postsecondary outcomes for individuals with autism spectrum disorder (ASD) are notably lower than their neurotypical peers. Forty-two percent of students with ASD present with normal…
