Symmetry studies in autism are inconclusive possibly due to different types of stimuli used which depend on either local or global cues. Therefore, this study compared symmetry detection between 20 autistic and 18 non-autistic adults matched on age, IQ, gender and handedness, using contour integration tasks containing open and closed contours that…

Stephenson, Kevin G.; Norris, Megan; Butter, Eric M. – Journal of Autism and Developmental Disorders, 2023
Previous research has identified possible sex-based differences in restricted and repetitive behaviors in autism spectrum disorder (ASD). However, this finding is mixed, particularly among preschool-aged children. We investigated the presence of sex-based differences in parent-rated ASD symptomatology, using the Autism Spectrum Rating Scale…

This study explores sex-differences in (a) rates and profiles of autism symptoms as well as in (b) the contribution of intellectual quotient (IQ) to autism symptom presentation in Down syndrome (DS). Participants were 40 males and 38 females with DS, aged 6 to 23 years. Autism symptoms were rated through the Autism Diagnostic Observation…

Background: Sensory processing differences are reported both in children with ADHD and in children with autism. Given the substantial overlap between autism and ADHD, the current study examined which sensory features were uniquely predictive of autistic traits after controlling for ADHD symptoms, age, IQ, and sex in a sample of children and…

Sturrock, Alexandra; Marsden, Antonia; Adams, Catherine; Freed, Jenny – Journal of Autism and Developmental Disorders, 2020
Female children with autism spectrum disorder (FwASD) and performance intelligence quotient (PIQ) over 70 were compared with male children with ASD (MwASD) and typically developing (TD) controls (age 8-11 years) using a range of language and pragmatic measures. Functional ability was assessed using clinical observations and parent, teacher and…

Markiewicz, Katarzyna; Kaczmarek, Bozydar L. J.; Filipiak, Sara – Journal of Autism and Developmental Disorders, 2021
The study aimed to identify the mediating role of emotional intelligence and social competences in the relationship between gender and broad autism phenotype (BAP) as well as between age and BAP. It comprised 85 parents of children with ASD. They completed the questionnaires of Autism-Spectrum Quotient, social competences, and emotional…

Girls and boys might differ in autistic symptoms and associated cognitive difficulties such as executive function (EF). We investigated sex differences in the relationship between parent rated EF and autistic symptoms in 116 children and adolescents (25 girls) aged 5-19 years with an intelligence quotient above 70 and an autism spectrum disorder…

Kuzmanovic, Bojana; Rigoux, Lionel; Vogeley, Kai – Journal of Autism and Developmental Disorders, 2019
Previous research has demonstrated irrational asymmetry in belief updating: people tend to take into account good news and neglect bad news. Contradicting formal learning principles, belief updates were on average larger after better-than-expected information than after worse-than-expected information. In the present study, typically developing…

Many neurodevelopmental disorders (NDDs) share common learning and behavioural impairments, as well as features such as dysregulation of the oxytocin hormone. Here, we examined DNA methylation (DNAm) in the 1st intron of the oxytocin receptor gene, "OXTR," in patients with autism spectrum (ASD), attention deficit and hyperactivity (ADHD)…

Harmsen, Irene E. – Journal of Autism and Developmental Disorders, 2019
Empathy is an essential component of human social life. It requires the ability to understand another's mental state and respond with an appropriate emotion or action. Individuals with autism spectrum disorder (ASD) have been described to exhibit atypical empathic responses which limit communication and social interactions. This review highlights…

This meta-analysis updated evidence regarding sensory over-responsivity (SOR), under-responsivity (SUR) and seeking symptoms in individuals with autism spectrum disorders (ASDs) relative to typical controls and those with other conditions. Fifty-five questionnaire studies included 4606 individuals with ASD. Moderators tested were age, IQ, male…

Peñuelas-Calvo, Inmaculada; Sareen, Aditya; Sevilla-Llewellyn-Jones, Julia; Fernández-Berrocal, Pablo – Journal of Autism and Developmental Disorders, 2019
We conducted a meta-analysis of 18 studies to establish whether a relation exists between Reading the Mind in the Eye Test (RMET) performance and intelligence quotient (IQ) in individuals diagnosed with autism-spectrum disorders (ASD) and controls, taking into account relevant characteristics such as age, gender, and autism quotient. Our findings…

Safer-Lichtenstein, Jonathan; Hamilton, Jillian C.; McIntyre, Laura Lee – Journal of Autism and Developmental Disorders, 2019
We reviewed the demographic reporting practices and diversity of participants in published randomized controlled trial studies of group-based social skills interventions (GSSIs) for individuals with autism spectrum disorder (ASD). A total of 17 studies met inclusionary criteria. Results of this review suggest that the majority of published RCTs…

Channell, Marie Moore; Hahn, Laura J.; Rosser, Tracie C.; Hamilton, Debra; Frank-Crawford, Michelle A.; Capone, George T.; Sherman, Stephanie L. – Journal of Autism and Developmental Disorders, 2019
We examined autism spectrum disorder (ASD) risk in a large national sample of 203 individuals with Down syndrome, 6-25 years old, to determine the association of ASD risk with age, sex, IQ, adaptive behaviors, and maladaptive behaviors. We used a two-pronged approach by (1) considering ASD symptomatology continuously across the sample of…

Prior studies of sex-based differences in autism spectrum disorder (ASD) have yielded mixed findings. This study examined ASD symptom severity and functional correlates in a sample of 34 high-functioning females with ASD (HFASD; M age = 8.93; M IQ = 104.64) compared to 34 matched males (M age = 8.96; M IQ = 104.44) using the Social Responsiveness…
