The present study examined the production of inalienable possession with body parts in Spanish among 20 school-age children of Mexican-born parents born and raised in the United States. The results were compared to those of 20 first-generation immigrant parents (main input providers), 27 Spanish-dominant children of similar age, and 12 Spanish…

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…

Almost every upper- and middle-class family in Saudi Arabia has a foreign housemaid who does the housework and takes care of the children. This study aims to find out whether foreign housemaids have an impact on children's acquisition of Arabic, the children's first language. Surveys with 300 mothers with children under the age of six revealed…

Socioeconomic disparities in early language are widespread and have long-lasting effects. The aim of this study is to investigate when social gaps in language problems arise and how they change across the first years of schooling. We address this question in two large longitudinal Norwegian datasets: the Behavior Outlook Norwegian Developmental…

It is said that children are amazing at acquiring their first language (L1); by the time they reach school age, they are using complex grammar and demonstrating a wide vocabulary. Even more impressive, these young learners might show up at school with two languages in their toolbox or add a second language (L2) with far less effort than older…

This is the first international and interdisciplinary handbook to offer a comprehensive and an in-depth overview of findings from contemporary research, theory, and practice in early childhood language education in various parts of the world and with different populations. The contributions by leading scholars and practitioners are structured to…

Poverty of the stimulus has been at the heart of ferocious and tear-filled debates at the nexus of psychology, linguistics, and philosophy for decades. This review is intended as a guide for readers without a formal linguistics or philosophy background, focusing on what poverty of the stimulus is and how it's been interpreted, which is…

There is considerable controversy over the factors that shape infants' developing knowledge of grammar. Work with artificial languages suggests that infants' ability to track statistical regularities within the speech they hear could, in principle, support grammatical development. However, little work has tested whether infants' performance on…

A surprising comprehension-production asymmetry in subject-verb (SV) agreement acquisition has been suggested in the literature, and recent research indicates that task-specific as well as language-specific features may contribute to this apparent asymmetry across languages. The present study investigates when during development children acquiring…

The study examines phases in developing specification of grammatical marking of emergent clause-combining (CC) as indicative of children's growing ability to integrate two or more independent predications. To this end, both intra- and inter-clausal analyses were applied to all CC utterances produced by three Hebrew-acquiring children aged 2;0-3;0,…

This paper revisits the longstanding observation that children produce modal verbs (e.g., must, could) with their root meanings (e.g., abilities, obligations) by age 2, typically a year or more earlier than with their epistemic meanings (e.g., inferences). Established explanations for this "Epistemic Gap" argue that epistemic language…

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…

Teachers and parents intuitively judge the 'level' of the child and the 'level' of the text and try to match them; they know that overestimation or underestimation of either will be met with restlessness or boredom. In this way, they have an empirical understanding of Vygotsky's ZPD--the zone of proximal development he envisioned as measuring the…

Children seem to be relatively delayed in their comprehension of the verbal "be"-passive in English, compared to their acquisition of other constructions of object-movement such as "wh"-questions and unaccusatives. Prior work has found that children's performance on these passives can be affected by the verb's lexical…

There is substantial evidence that children's apparent omission of grammatical morphemes in utterances such as "She play tennis" and "Mummy eating" is in fact errors of commission in which contextually licensed unmarked forms encountered in the input are reproduced in a context-blind fashion. So how do children stop making such…
