Maria Montessori's work remains popular and influential around the world. She provided fascinating descriptions of her observations of children's learning. Yet at the heart of her work is a lacuna: the issue of how children learn their first language. For Montessori, it was a marvel, a miracle--but a mystery. We argue that the later philosophy of…

Computational models of reading have tended to focus on the cognitive requirements of mapping among written, spoken, and meaning representations of individual words in adult readers. Consequently, the alignment of these computational models with behavioural studies of reading development has to date been limited. Models of reading have provided us…

Language is the basis of human communication and is the most important key to complete mental development and thinking. Therefore, children must learn to communicate using appropriate language. For this to happen, the development of language in the child must be understood as a biological process, complete with internal laws and with marked stages…

In "Emile," Rousseau advances significant ideas about language, language learning and teaching: He posits a universal natural language that develops as the child matures; focuses on 'private' words invented by children, on the challenge facing children in their understanding of exceptions to general rules of the mother tongue and on…

Over the past 50 years, scientists have made amazing discoveries about the origins of human language acquisition. Central to this field of study is the process by which infants' perceptual sensitivities gradually align with native language structure, known as "perceptual narrowing." Perceptual narrowing offers a theoretical account of…

A newborn arrives in this world with the inherent capacity to learn. This includes simple reflexes such as sucking, Moro reflexes, grasping etc. These "pre-installed" capacities help the baby to survive, particularly in the early months before there has been time to gaining new capabilities through learning. Once an infant starts to…

Children's understanding of passives of certain mental state predicates appears to lag behind passives of so-called actional predicates, an asymmetry that has posed a major empirical challenge for theories of passive acquisition. This paper argues against the dominant view in the literature that treats the predicate-based asymmetry as…

Neural network models have recently made striking progress in natural language processing, but they are typically trained on orders of magnitude more language input than children receive. What can these neural networks, which are primarily distributional learners, learn from a naturalistic subset of a single child's experience? We examine this…

This review addresses the question of how early access to sign language influences the development of deaf children with cochlear implants (CIs) by examining the literature surrounding the topic across the domains of spoken/written language development, cognitive development, and sociocultural development. Although research in the realm of…

A grandmother attempts to teach her four-year-old granddaughter the multiplication tables using simple repetition, but they repeatedly start over at 'three fives'; the child keeps coming up with 'thirty-five'. We consider three possible explanations: self-perpetuating frequency of behavior, saliency of memory and Vygotsky's next or proximal zones…

The influence of adverse childhood experiences (ACEs) on the developing child across several domains of functioning has much theoretical and empirical support. Yet, surprisingly, the impact of ACEs on the development of language skills specifically remains somewhat understudied. The present report provides a brief review of research on ACEs and…

"Early Childhood Development" celebrates the rich diversity of development among children in all neighborhoods in the United States and around the globe. It examines the physical, social, emotional, linguistic and intellectual characteristics of children from birth through age 8. Within each development domain, it considers the typical…

Around their first birthdays, infants begin to point, walk, and talk. These abilities are appreciable both by researchers with strictly standardized criteria and caregivers with more relaxed notions of what each of these skills entails. Here, we compare the onsets of these skills and links among them across two data collection methods: observation…

Kathy Hirsh-Pasek is the Stanley and Debra Lefkowitz Faculty Fellow in the Department of Psychology at Temple University and a Senior Fellow at the Brookings Institution. She is the past president of the International Society for Infant Studies, served as the Associate Editor of "Child Development" and is on the governing counsel of the…

In response to Golinkoff, Hoff, Rowe, Tamis-LeMonda, and Hirsh-Pasek's (2018) commentary, we clarify our goals, outline points of agreement and disagreement between our respective positions, and address the inadvertently harmful consequences of the word gap claim. We maintain that our study constitutes a serious empirical challenge to the word…
