Human movement plays a foundational role in cognition and learning. This topical collection brings together theoretical and empirical work examining how gestures, physical activity, and virtual movement enhance learning in language, multimedia, and activity-based learning. Regarding language learning, interacting with virtual object improves…

The present study examined adults' understanding of children's early word learning. Undergraduates, non-parents, parents, and Speech-Language Pathologists (N = 535, 74% female, 56% White) completed a survey with 11 word learning principles from the perspective of a preschooler. Questions tested key principles from early word learning research. For…

When linguistic input contains inconsistent use of grammatical forms, children produce these forms more consistently, a process called "regularization." Deaf children learning American Sign Language from parents who are non-native users of the language regularize their parents' inconsistent usages. In studies of artificial languages…

Higher-order thinking is relational reasoning in which multiple representations are linked together, through inferences, comparisons, abstractions, and hierarchies. We examine the development of higher-order thinking in 64 preschool-aged children, observed from 14 to 58 months in naturalistic situations at home. We used children's spontaneous talk…

Organized semantic representations encoding across- and within-domain distinctions are a hallmark of mature cognition, and understanding how they change with experience and learning is a key endeavor in developmental science. Existing computational modeling studies provide a mechanistic framework for understanding how structured semantic…

The words in children's language learning environments are strongly predictive of cognitive development and school achievement. But how do we measure language environments and do so at the scale of the many words that children hear day in, day out? The quantity and quality of words in a child's input are typically measured in terms of total amount…

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…

Previous research has shown that home environment plays an important role in children's early language skills. Yet, few researchers have examined the unique role of family-level factors (socioeconomic status [SES], household chaos) on children's learning or focused on the longitudinal processes that might explain their relations to children's…

The aim of this study was to develop a measurement approach to assess the learning opportunities provided by parents to their young children with autism spectrum disorder during a free play task and to examine the relationship between learning opportunities and child performance on measures of cognition, autism spectrum disorder symptoms, and…

There are clear associations between the overall quantity of input children are exposed to and their vocabulary acquisition. However, by uncovering specific features of the input that matter, we can better understand the mechanisms involved in vocabulary learning. We examine whether exposure to "wh"-questions, a challenging quality of…

Both early childhood maternal language input and the quality of classroom instruction in elementary school have been shown to be important environmental supports in predicting children's literacy skill development. However, no studies have simultaneously examined these two environmental supports in relation to children's early language skills and…

Purpose: This study investigates the heritability of language, speech, and nonverbal cognitive development of twins at 4 and 6 years of age. Possible confounding effects of twinning and zygosity, evident at 2 years, were investigated among other possible predictors of outcomes. Method: The population-based twin sample included 627 twin pairs and 1…

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…

This cross-linguistic study investigated whether the native language has any influence on lexical composition among Italian (N = 125) and Finnish (N = 116) very preterm (born at <32 gestational weeks) children at 24 months (controls: 125 Italian and 146 Finnish full-term children). The investigation also covered the effect of maternal education…

Shared reading represents an established practice to foster preschool vocabulary development, particularly when coupled with explicit instruction in word meanings. However, a question remains as to whether explicit word definitions detract from story delivery and hence language learning. Accordingly, this study compared explicit versus…
