Research findings on the prevalence and characteristics of behavioral problems of children with hearing loss (HL) are not consistent. The aim of this study was to compare the behavioral problems of children with HL, with typical development (TD) and with autism spectrum disorder (ASD); and to determine the factors affecting behavioral problems in…

Brain age, a measure of biological aging in the brain, has been linked to psychiatric illness, principally in adult populations. Components of socioeconomic status (SES) associate with differences in brain structure and psychiatric risk across the lifespan. This study aimed to investigate the influence of SES on brain aging in childhood and…

Homework problems are frequently encountered, especially among youth with ADHD. The Homework Problems Checklist (HPC) is a parent-rated questionnaire to assess homework problems that was studied with children but not extensively with teens. We assessed the psychometric properties of the HPC with teens with and without ADHD. Firstly, the factor…

During the last decades, global interest in learning English as a foreign language has increased, encouraging countries to include it in school education. This trend was followed by the Chilean Ministry of Education, which suggests teaching English based on a communicative approach starting in early childhood education. To foster students'…

Relative clauses (RCs) are complex syntactic structures because they consist of multiple clauses and involve syntactic movement. RCs are known as a reliable clinical marker of syntactic impairment across many different languages and populations. Children with autism spectrum disorders (ASD) struggle with the comprehension and production of RCs,…

Effective communication is a fundamental aspect of children's daily living, enabling interaction with adults and peers. A rich literature suggests that communicative abilities develop with age, while little is known about cross-cultural differences and similarities. This study presents a comparison of the communicative performance of Finnish (n =…

Literacy exposure checklists that assess parental picture book knowledge (Parental Title Checklist [PTC] and Parental Author Checklist [PAC]) have been developed as proxy measures for literacy environments. Although previous research suggests that parental picture book knowledge is a strong predictor of language skills for preschoolers older than…

Understanding executive functions (EFs) development is of high value to global developmental science. Recent calls for a more inclusive and equitable developmental science argue that tasks and questionnaires that are developed using only a subset of the population are not likely to be appropriate for EFs measurement in global contexts unless…

This study examines the reliability of parental concern (PC) as an indicator for mental disorders in preschool-aged children in a clinical setting, aiming to establish sensitivity and specificity, evaluate PC's predictive value for specific diagnoses, and explore the influence of child age on predictions. The sample comprises 574 children referred…

Vocabulary checklists completed by caregivers are a common way of measuring children's vocabulary knowledge. We provide evidence from checklist data from 31 children with and without autism spectrum disorder. When asked to report twice about whether or not their child produces a particular word, caregivers are largely consistent in their…

While semantic and syntactic properties of verb meaning can impact the success of verb learning at a single age, developmental changes in how these factors influence acquisition are largely unexplored. We ask whether the impact of syntactic and semantic properties on verb vocabulary development varies with age and language ability for toddlers…

Emerging research suggests that adolescents at high-achieving schools (HAS) in Western societies are at elevated risk for problem behaviours. This cross-sectional study explored whether adolescents attending HAS in a non-Western setting show similar risk patterns and if contextual (school-, family-, and peer-based) factors typically associated…

Mounting evidence finds that early life environmental factors increased the probability of autism spectrum disorder. We estimated prospective associations between early life environmental factors and autism spectrum disorder symptoms in children at the age of 2 years in a population-derived birth cohort, the Barwon Infant Study. Autism spectrum…
