Prevalence of Motor Difficulties in Autism Spectrum Disorder: Analysis of a Population-Based CohortIn this population-based cohort that included 2,084 children with autism aged ≤6 years, over one-third met the criteria for motor difficulties

Eye Gaze in Autism Spectrum Disorder: A Review of Neural Evidence for the Eye Avoidance HypothesisReduced eye contact early in life may play a role in the developmental pathways that culminate in a diagnosis of autism spectrum disorder. However, there are contradictory theories regarding the neural mechanisms involved. According to the amygdala theory of autism, reduced eye contact results from a hypoactive amygdala that fails to flag eyes as salient. However, the eye avoidance hypothesis proposes the opposite-that amygdala hyperactivity causes eye avoidance. This review evaluated studies that measured the relationship between eye gaze and activity in the 'social brain' when viewing facial stimuli.

Atypical nested 22q11.2 duplications are associated with neurodevelopmental phenotypes including autism spectrum disorder with incomplete penetranceOur findings contribute to the genotype–phenotype data for atypical nested 22q11.2 duplications, with implications for genetic counseling

Characterizing the interplay between autism spectrum disorder and comorbid medical conditions: An integrative reviewWe review medical conditions that have been repeatedly highlighted as sharing the strongest associations with ASD-epilepsy, sleep, as well as gastrointestinal and immune functioning

Parental perspectives of the everyday experiences of uncertainty among young children on the autism spectrumAnxiety commonly co-occurs in autism. Exploring and understanding potential underpinning mechanisms contributing to and maintaining anxiety in the early years is important in managing anxiety. Intolerance of uncertainty (IU), a tendency to find uncertainty difficult, is a transdiagnostic mechanism contributing to anxiety, but little is known about how IU may be experienced in young children on the autism spectrum. This study investigated parental perspectives of children's experiences of uncertainty.

Perceived Support Needs of School-Aged Young People on the Autism Spectrum and Their CaregiversWith increasing demands for health, disability and education services, innovative approaches can help distribute limited resources according to need. Despite an increased focus on support needs within the clinical pathway and policy landscape, the body of research knowledge on this topic is at a relatively early stage. However, there appears to be a sense of unmet support needs and dissatisfaction with the provision of required support following an autism diagnosis amongst caregivers of young people on the spectrum.

Continuity of temperament subgroup classifications from infancy to toddlerhood in the context of early autism traitsOur previous cross-sectional investigation (Chetcuti et al., 2020) showed that infants with autism traits could be divided into distinct subgroups based on temperament. This longitudinal study builds on this existing work by exploring the continuity of temperament subgroup classifications and their associations with behavioral/clinical phenotypic features from infancy to toddlerhood.

Do children with autism 'switch off' to speech sounds? An investigation using event-related potentialsAutism is a disorder characterized by a core impairment in social behaviour. A prominent component of this social deficit is poor orienting to speech.
