Developmental vitamin D deficiency increases foetal exposure to testosteroneAutism spectrum disorder (ASD) is a group of neurodevelopmental disorders which are more common in males. The 'prenatal sex steroid' hypothesis links excessive sex-steroid exposure during foetal life with the behavioural differences observed in ASD. However, the reason why sex steroid exposure may be excessive remains unclear. Epidemiological studies have identified several environmental risk factors associated with ASD, including developmental vitamin D (DVD) deficiency.

Where were those rabbits? A new paradigm to determine cerebral lateralisation of visuospatial memory function in childrenIn the majority of people, functional differences are observed between the two cerebral hemispheres: language production is typically subserved by the left...

CNTNAP2 variants affect early language development in the general populationWe tested the hypothesis that these CNTNAP2 variants affect communicative behavior, measured at 2 years of age in a large epidemiological sample...

Autism Early Intervention Providers: Their Priorities, Use of Empirically Supported Practices, and Professional Development NeedsAutism early intervention research has indicated a research-to-practice gap, including continued use of practices with inadequate research support, and insufficient use of empirically supported practices. The present study explored the processes and mechanisms through which providers working with young children on the autism spectrum learn, select, and implement the various practices in their clinical repertoires.

Parsing the heterogeneity of social motivation in autismSocial motivation is posited as a key factor in the expression of the autism phenotype. However, lack of precision in both conceptualization and measurement has impeded a thorough understanding of its diverse presentation and associated outcomes. This study addresses this gap by identifying subgroups of autism characterized by deficits in distinct facets of social motivation, relative to normative benchmarks.

Investigating the impact of autistic children's feeding difficulties on caregiversThe aim of this study was to investigate the influence of children's autism characteristics, sensory profiles and feeding difficulties on caregiver-reported impact at mealtimes.

Arcuate fasciculus and pre-reading language development in children with prenatal alcohol exposurePrenatal alcohol exposure (PAE) contributes to widespread neurodevelopmental challenges, including reading, and has been associated with altered white matter. Here, we aimed to investigate whether arcuate fasciculus development is associated with pre-reading language skills in young children with PAE.

Caregiver sensitivity predicts infant language use, and infant language complexity predicts caregiver language complexity, in the context of possible emerging autismWhile theory supports bidirectional effects between caregiver sensitivity and language use, and infant language acquisition-both caregiver-to-infant and also infant-to-caregiver effects-empirical research has chiefly explored the former unidirectional path. In the context of infants showing early signs of autism, we investigated prospective bidirectional associations with 6-min free-play interaction samples collected for 103 caregivers and their infants (mean age 12-months; and followed up 6-months later).

The effects of prenatal bisphenol A exposure on brain volume of children and young miceBisphenol A (BPA) is a synthetic chemical used for the manufacturing of plastics, epoxy resin, and many personal care products. This ubiquitous endocrine disruptor is detectable in the urine of over 80% of North Americans.
