Most theories of learning would predict a gradual acquisition and refinement of skills as learning progresses, and while some highlight exponential growth, this fails to explain why natural cognitive development typically progresses in stages. Models that do span multiple developmental stages typically have parameters to "switch" between…

This established text--now revised and updated--reveals how spoken language skills are acquired and how they affect children's later reading and writing achievement. With a unique focus on the needs of educators, the book examines the foundations of language in the developing brain. It explores the relationship of language processes to core…

Theory of Mind (ToM) is a foundational skill related to understanding the thoughts, beliefs, and desires of oneself and others. There are child factors that play an important role in the development of ToM (e.g., language and vocabulary) as well as environmental factors (e.g., conversations among family members and socioeconomic status). In this…

Two experiments explored the consolidation of spoken words, and assessed whether post-sleep novel competitor effects truly reflect engagement of these novel words in competition for lexical segmentation. Two types of competitor relationships were contrasted: the onset-aligned case (such as "frenzylk"), where the novel word is a close variant of…

Studies of communication in early infancy and childhood have highlighted the significance of rhythm, sound and music for emotional and social development. There is, however, little detailed empirical data on the emergence of naturalistic music-related behaviour by children in the early years. The aim of this work is to examine instances of…

The Matthew effect is often used as a metaphor to describe a widening gap between good and poor readers over time. In this study we examined the development of individual differences in reading and cognitive functioning in children with reading difficulties and normal readers from Grades 1 to 3. Matthew effects were observed for individual…

Utilizing a developmental-ecological framework, the purpose of this study was to understand the unique impact of multiple maternal risks across time on ethnically diverse, low-income, preschool children's cognitive skills, pro-social behaviors, and behavior problems. Additionally, this study sought to understand the variability of maternal risks…

Numerous studies show that children's language ability is related to false-belief understanding. However, there is considerable variation in the size of the correlation reported. Using data from 104 studies (N=8,891), this meta-analysis determines the strength of the relation in children under age 7 and examines moderators that may account for the…

Because of the substantial impact on outcomes for children, states and school districts across the country are addressing issues surrounding early learning opportunities and school readiness for young children. Full-day kindergarten plays an important role in both. Colorado has made significant investments in full-day kindergarten as a means of…

Two alternative hypotheses can be used to explain how young children acquire the cardinal meaning of small-number words. The first stresses the role of counting and predicts better performance when the items are presented in succession. The second considers the role of subitizing and predicts better performance when the items are presented…

Children sometimes seem to expect words to have mutually exclusive meanings in certain contexts of early word learning. In 2 studies, 12- to 24-month-old children and their parents were videotaped as they engaged in conversations while playing with sets of toys (sea creatures, vehicles, doll clothing) in free-play, storytelling, and categorization…

The confounding of chronological and educational age and of schooling and socioeconomic status are persistent problems in the study of the cognitive consequences of schooling. The educational system among the Kharwar in India provides a natural experiment to overcome these problems, since it shows neither source of confounding. The sample…

A preschool program in rural Bangladesh was evaluated in terms of cognitive and social outcomes of children. The preschools provided a half-day program, 6 days a week, with free play, stories, and instruction in literacy and math. Four hundred children between 4.5 and 6.5 years were assessed, half in preschools and half in villages where there…

Science and social studies have much to offer to all learners--including those with disabilities. However, instruction in these subjects has often been overlooked in the quest to better understand and improve leaning in English/language arts and mathematics. As we demonstrate in this paper, science and social studies help students attain skills,…

We review the main findings of the Jyvaskyla of Dyslexia (JLD) which follows the development of children at familial risk for dyslexia (N = 107) and their controls (N = 93). We will illustrate the development of these two groups of children at ages from birth to school entry in the skill domains that have been connected to reading and reading…
