Background: Low socioeconomic status is associated with lower cognitive performance and long-term disparities in achievement and success. However, not all children from low-income backgrounds exhibit lower cognitive performance. Characterizing the factors that promote such resilience in youth from low-income households is of crucial importance.…

Multidimensional theory of mind assessments should include items assessing both explicit theory of mind (theory of mind knowledge) and applied theory of mind (application of theory of mind knowledge in real-life contexts). However, the two theory of mind scores cannot be interpreted collectively to identify children having mismatched explicit and…

A review of clinical records was conducted for children with developmental, emotional, and behavioral difficulties who were assessed with both the Wechsler preschool and primary scale of intelligence-third edition (WPPSI-III[superscript CDN]; Wechsler, 2004) and the Leiter international performance scale--revised (Leiter-R; Roid & Miller,…

Tests of measurement invariance are essential to determining whether individual scores or group averages are comparable across populations. While international comparisons of mean IQ scores are common, tests of measurement invariance for intelligence test batteries (necessary for comparisons to be empirically supported) are rare. In this study,…

Multi-sensory environments are widely used with autistic children. However, there are no data on how autistic children choose to spend time in the room and how this relates to their sensory, behavioural and intellectual profiles. We observed the frequency and duration of visits to multi-sensory environment equipment of 41 autistic children during…

Trajectories of cognitive and neural development suggest that, despite early emergence, the ability to extract environmental patterns changes across childhood. Here, 5- to 9-year-olds and adults (N = 211, 110 females, in a large Canadian city) completed a memory test assessing what they remembered after watching a stream of shape triplets: the…

The late positive potential (LPP), an event-related potential reflecting affective processing, may exhibit developmental shifts in magnitude and scalp location. In the present longitudinal study, 501 youth (47.3% female; 89.4% White; 12.0% Hispanic) completed the emotion interrupt task to elicit the LPP to neutral, positive, and negative images at…

The association between parents' work-family conflicts and children's academic outcomes is an understudied topic. The present research investigates the role of quadratic measures--parental working hours' scale, parental age, parental interaction quality, and learning materials at home--in children's cognitive outcomes. It employs a community…

Studies of hemispheric specialization have traditionally cast the left hemisphere as specialized for language and the right hemisphere for spatial function. Much of the supporting evidence for this separation of function comes from studies of healthy adults and those who have sustained lesions to the right or left hemisphere. However, we know…

Introduction: This review aimed to synthesize and review computerized cognitive rehabilitation studies on children with disabilities to confirm their effectiveness. Methods: In 2021, an electronic search of academic articles was performed using PubMed, CINAHL, Science Direct, and Cochrane databases. Results: First, two experienced researchers…

The aim of this study was to examine genetic variations underlying the early neurodevelopmental outcome of developmental disabilities (DDs). The study cohort consisted of 191 children with DDs. Diagnosis was assessed at baseline and at the index age (72-84 months). Exome sequencing was conducted and putative risk variants were identified.…

Background: Children with Prader-Willi Syndrome (PWS) display impaired pretend play abilities, reflective of broader social-cognitive challenges. Pretend play interventions for children with PWS demonstrate preliminary efficacy for improving cognitive and affective processes in play. It is unknown which specific intervention strategies, such as…

Children are limited in visual search accuracy and this ability increases from childhood to adolescence. Developmental limitations in visual search could be related to children's difficulties in efficiently planning and executing their search, often assessed with cancellation tasks. However, few studies have examined age-related changes in visual…

In some contexts (e.g., legal and medical), it is imperative that children indicate when they do not understand an adult's question. Yet, little research has examined children's clarification requests. We asked 122 4- to 9-year-olds tricky and simple interview questions to assess how often and how children request clarification in interviews, the…

This article assesses nutritional intake and adequacy in children with autism spectrum disorder (ASD), subdiagnostic autistic symptoms and children with typical development (TD). In total, 77 children diagnosed with ASD, 40 with subdiagnostic autistic symptoms and 333 children with TD were assessed. A validated food frequency questionnaire was…
