The Development of Lateralized Brain Oscillations in Infants
The lateralization of brain activity is important for language processing and attention, and atypical patterns of lateralization have been linked to many neurodevelopmental disorders, including autism spectrum disorder (ASD). However, the developmental timing of these patterns and their relationship to emerging ASD characteristics are unclear. In this study, we used data from EEG‐IP (International Infant EEG Data Integration Platform), a longitud…
Disentangling global and domain‐level adaptive behavior trajectories among children with autism spectrum disorder
BACKGROUND: Heterogeneity in adaptive behavior abilities among people with autism spectrum disorder (ASD) is expressed not only as uneven levels of impairment across domains, but also in the developmental trajectories of adaptive skills. We studied the question of whether, after accounting for global adaptive behavior development, we find evidence of heterogeneity in the trajectories of specific domains of adaptive behavior. METHODS: A sample of …
Neural mechanisms of language development in infancy
Understanding the neural processes underpinning individual differences in early language development is of increasing interest, as it is known to vary in typical development and to be quite heterogeneous in neurodevelopmental conditions. However, few studies to date have tested whether early brain measures are indicative of the developmental trajectory of language, as opposed to language outcomes at specific ages. We combined recordings from two …
Children with Disabilities in Canada during the Covid-19 Pandemic
Children with disabilities were especially vulnerable during the COVID-19 pandemic, and policies designed to mitigate its effects were limited in addressing their needs. We analyzed Canadian policies related to children with disabilities and their families during the COVID-19 pandemic to identify the extent to which these policies aligned with the United Nations Convention on the Rights of Persons with Disabilities (UN CRPD) and responded to thei…

Middle‐childhood executive functioning mediates associations between early‐childhood autism symptoms and adolescent mental health, academic and functional outcomes in autistic children
BACKGROUND: Executive functioning (EF) varies in children with autism spectrum disorder (ASD) and is associated with clinical symptoms, academic, and adaptive functioning. Here, we examined whether middle-childhood EF mediates associations between early-childhood autism symptoms and adolescent outcomes in children with ASD. METHODS: The Pathways in ASD Cohort comprising children recruited at the time of ASD diagnosis (at 2-4 years-of-age) and fol…
Predictors of language regression and its association with subsequent communication development in children with autism
BACKGROUND: Language regression, broadly defined as the loss of acquired language skills in early childhood, is a distinctive feature of autism. Little is known about the factors underlying regression or the prognosis of children who exhibit regression. We examine potential predictors of language regression and test its association with language development in a prospective longitudinal sample of children with autism spectrum disorder (ASD) from …
Annual Research Review
BACKGROUND: Autism presents with similar prevalence and core impairments in diverse populations. We conducted a scoping review of reviews to determine key barriers and innovative strategies which can contribute to attaining universal health coverage (UHC), from early detection to effective interventions for autism in low- and middle-income countries (LAMIC). METHODS: A systematic literature search of review articles was conducted. Reviews relevan…
Ethical dimensions of translational developmental neuroscience research in autism
BACKGROUND: Since the 1990s, increasing research has been devoted to the identification of biomarkers for autism to help attain more objective diagnosis; enable early prediction of prognosis; and guide individualized intervention options. Early studies focused on the identification of genetic variants associated with autism, but more recently, research has expanded to investigate neurodevelopmental markers. While ethicists have extensively discus…
Progress and gaps in Quebec’s autism policy
Autism spectrum disorder
Global Prevalence of Autism and Other Pervasive Developmental Disorders
We provide a systematic review of epidemiological surveys of autistic disorder and pervasive developmental disorders ( PDDs ) worldwide. A secondary aim was to consider the possible impact of geographic, cultural/ethnic, and socioeconomic factors on prevalence estimates and on clinical presentation of PDD . Based on the evidence reviewed, the median of prevalence estimates of autism spectrum disorders was 62/10 000. While existing estimates are v…
Constraints on the Timing of Infant Cognitive Change
Most studies of infant cognition focus on group data from single domains. Yet, without the multi-domain testing of the same infants longitudinally, such data cannot be used to evaluate whether the timing of cognitive change occurs in a domain-general
Faces Attract Infants' Attention in Complex Displays
Infant's face preferences have previously been assessed in displays containing 1 or 2 faces. Here we present 6‐month‐old infants with a complex visual array containing faces among multiple visual objects. Despite the competing objects, infants direct their first saccade toward faces more frequently than expected by chance (Experiment 1). The attention‐grabbing effect of faces is not selective to upright faces (Experiment 2) but does require the p…
