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…

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…

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)…

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…

Developmental dyslexia (DD) is a common reading disability, affecting 5% to 11% of children in North America. Children classified as having DD often have a history of early language delay (ELD) or language impairments. Nevertheless, studies have reported conflicting results as to the association between DD-ELD and the extent of current language…

Research addressing the relationship between vocabulary knowledge and second language (L2) listening comprehension has been conducted mostly using measures that tap orthographic vocabulary knowledge. The few studies that have used measures that tap phonological modality to delineate the relationship between vocabulary and L2 listening have focused…

This study examined the dimensionality of caregivers' child-directed talk and the association of child directed talk and children's language skills at age of 3 years in a sample of 63 low-SES dyads in low-SES homes. Exploratory factor analysis identified that caregivers' child directed talk is characterized by two dimensions: quantity and…

We explored reading comprehension development in children on the spectrum from pre-school to the first (YOS1) and third year of schooling (YOS3). Children were first assessed on meaning-related skills in pre-school. Forty-one children completed follow-up assessments of reading comprehension, reading accuracy, and listening comprehension in YOS1.…

This study aimed to explore whether early developmental abilities are related to future executive function (EF) in children with motor delays. Fourteen children with motor delays (Mean age = 10.76, SD = 2.55) were included from a larger study. Object interaction and developmental outcomes (Bayley-III) were evaluated at baseline and 3, 6, and 12…
