Children learn language by listening to speech from caregivers around them. However, the type and quantity of speech input that children are exposed to change throughout early childhood in ways that are poorly understood due to the small samples (few participants, limited hours of observation) typically available in developmental psychology. Here…

Reading comprehension is contingent on both oral language comprehension and word-level reading ability, skills that are thought to be intrinsically related in the early school years. However, while previous studies examining bidirectional relationships among oral vocabulary and reading development have generally found an association between word…

Despite the well-established role of lexis in proficiency in the four skills, a great deal of research has focused on the importance of vocabulary breadth and depth in reading. Therefore, the neglect of productive skills has motivated recent calls to inspect the impact of lexical dimensions on writing ability. Using Partial Least Squares…

Previous research links resting frontal gamma power to key developmental outcomes in young neurotypical (NT) children and infants at risk for language impairment. However, it remains unclear whether gamma power is specifically associated with language or with more general cognitive abilities among young children diagnosed with autism spectrum…

Numerous studies have evidenced the relationship between musical rhythm and language performances, derived from temporal acoustic signal processing. This relationship might be affected by different language experiences. Receptive and expressive vocabulary knowledge, phonological awareness, and musical rhythm perception and production were examined…

It is established that a greater rate of conversational turns (CTs) is associated with improved language outcomes for hearing children (HC). This study investigates the number of CTs experienced by deaf and hard of hearing (DHH) children and HC--a total of 10 children matched for age, gender and Special Educational Needs (SEN) in an Early Years…

Strong oral language skills are foundational for literacy development and begin before a child enters formal schooling. Oral language development has been related to pretend play abilities in children. Children, particularly those from disadvantaged areas, who enter school with low pretend play levels and oral language abilities, are at risk for…

Purpose: This study evaluates the extent to which automated indices of vocal development are stable and valid for predicting language in infants at increased familial likelihood for autism and/or language impairment and relatively lower likelihood infants. Method: A group of infants with autistic siblings (Sibs-autism; 20 infants) and a comparison…

Mastery motivation predicts achievement, but intricacies amongst preschoolers are unclear. In keeping with the Specificity Principle, school-age, and adolescent research demonstrates the importance of considering the "setting conditions" in which mastery motivation is observed. Here, Singaporean 4-year-olds' (N = 63)…

While CLIL programmes have been extensively researched for their impact on L2 learning outcomes, the relationship between young learners' L2 proficiency and subject knowledge has received less attention. This study aimed to address this research gap by examining the science content knowledge of two cohorts of Grade 5 students (n = 100) from two…

This study examines the development of children's social skills during the crucial transition from kindergarten to grade school. It explores the long-term connection between parenting styles and children's social skills. This study conducted a three-year longitudinal survey involving 121 children and their parents. The results show that early…

This study aimed to adapt and validate the Word Complexity Measure (WCM) for Persian-speaking toddlers. The WCM is a tool for assessing phonological complexity, originally proposed by Stoel-Gammon. The study was conducted in two phases: (1) adapting the WCM parameters to the Persian language and (2) conducting a validation study with 60…

Purpose: This study examines the effects of communication sample length on the reliability and convergent validity of six vocal measures for children with autism spectrum disorder (ASD) with minimal verbal skills. The results are expected to inform recommendations for the length of communication samples for clinical and research purposes. Method:…

This study examined the extent to which classroom quality (emotional and instructional climate) moderates the associations between teachers' beliefs about children, self-efficacy, and children's early language gains (receptive and expressive vocabulary). The study employed multilevel modeling with 606 preschool teachers and 2,536 preschool…

Preschool teachers' perceptions about relationships with students (teacher-child relationships [TCRs]) predict children's subsequent social competence (SC) and academic progress. Why this is so remains unclear. Do TCRs shape children's development, or do child attributes influence both TCRs and subsequent development? Relations between TCRs and…
