Prospective memory helps us to remember to perform tasks in the future. Prospective memory can be either time or event based. The goal of this study was to determine time- and event-based prospective memory in autistic adults across the life span. Autistic (n = 82) and non-autistic (n = 111) adults, aged between 30 and 86 years, performed the…

Sleep problems are prevalent in autism spectrum disorder (ASD) and have a range of causes, including circadian rhythm misalignment. However, little is known about sleep in autistic children with co-occurring attention deficit hyperactivity disorder (ADHD). A cross-sectional descriptive and analytic study was conducted in 87 autistic children and…

Several measures have been developed to assess loneliness in the general population. Here, we examined if, and how accurately, widely-used measures capture the experience of loneliness in autistic adults. A total of 203 autistic participants from the UK completed an online survey, which included two widely-used loneliness questionnaires: the…

Autistic individuals are at increased risk of experiencing various forms of victimization during their lifespan. This study analyses the self-reported prevalence of bullying victimization in autistic pre-adolescents and those with subthreshold autistic traits in comparison with peers without neurodevelopmental conditions. The sample was comprised…

Affective prosody recognition is an important area of research in autism spectrum conditions where difficulties in social cognition have been frequently observed. To probe into the mixed results reported in the literature, we conducted a systematic review with meta-analysis and examined potential factors that could explain the inconsistent…

Autism is associated with significantly higher rates of internalizing and externalizing disorders compared to neurotypical (NT) individuals. Emotion dysregulation (ED) is prevalent in autistic individuals and has been proposed to underlie both internalizing disorders and behavioral challenges in autism. This study sought to use a meta-analytic…

For autistic students receiving special education services, little is known about their relative strengths, weaknesses, and enjoyment across different math content areas; their overall math interest and persistence are also not well-studied. Using the 2017 eighth-grade National Assessment of Education Progress data, this study finds, relative to…

Little is known about the extent to which the healthcare needs of autistic older adults with intellectual disability differ from autistic older adults without intellectual disability. We conducted a cross-sectional retrospective cohort study of Medicare claims data from 2016 to 2017 to compare the prevalence of physical and mental health…

Although differences in DNA methylation have been associated with both syndromic and idiopathic autism, differential methylation has not been examined previously with respect to sex differences. The goals of this study were to (1) identify differences in the DNA methylation profiles of lymphoblastoid cell lines derived from a subgroup of severely…

Face recognition is a fundamental function that requires holistic processing. Differences in face processing have been consistently identified in autistic children, but it is unknown whether these differences persist across the adult lifespan. Using event-related functional magnetic resonance imaging, we measured holistic face processing with a…

Although person-first language is commonly used in many professional settings, this practice has received criticism from self-advocates and scholars who believe that identity-defining features, such as autism, cannot be separated from the individual. Arguments have been made that person-first language may perpetuate stigma by drawing attention to…

Repetitive and restricted behaviours are a core feature of autism, and cognition in autistic individuals may also be repetitive and restricted. We aimed to investigate the relationship between repetitive behaviours and repetitive thinking. We predicted that autistic people would experience more repetitive, perseverative, visual and negative…

Despite efforts to detect autism spectrum disorder during toddlerhood, many children with autism spectrum disorder remain undiagnosed until school age. To identify characteristics of children whose autism spectrum disorder might not be diagnosed during toddlerhood, this study used archived Autism Diagnostic Interview-Revised records to examine the…

Most current autism research focuses on Western countries, where service availability and cultural experiences differ from those of individuals living in Asian countries, where collectivistic cultural values prevail and understanding of autism is emerging. By gathering data from Vietnamese parents of autistic children (N = 339), the current…

Improving autism spectrum disorder screening and referral in primary care may reduce autism spectrum disorder disparities for Latino children. The REAL-START intervention aimed to increase primary care provider adherence to autism spectrum disorder and developmental screening guidelines, and to increase Early Intervention referral for children at…
