The account that word learning starts in earnest during the second year of life, when infants have mastered the disambiguation skills, has recently been challenged by evidence that infants during the first year already know many common words. The preliminary ability to rapidly map and disambiguate linguistic labels was tested in Italian-speaking…

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…

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…

Research on the early lexical-semantic system has described how toddlers organize word representations based on semantic and phonological features. This study is a longitudinal investigation of the development of this organization during infancy. Middle-high socioeconomic status Mexican toddlers (n = 28, 15 female) were presented with a…

Purpose: We examined the neurocognitive bases of lexical morphology in children of varied reading abilities to understand the role of meaning-based skills in learning to read with dyslexia. Method: Children completed auditory morphological and phonological awareness tasks during functional near-infrared spectroscopy neuroimaging. We first examined…

Socioeconomic status (SES) has been repeatedly linked to the developmental trajectory of vocabulary acquisition in young children. However, the nature of this relationship remains underspecified. In particular, despite an extensive literature documenting young children's reliance on a host of skills and strategies to learn new words, little…

More than half the global population is estimated to be multilingual, yet research on autistic children who grow up in multilingual environments remains scant. We conducted a systematic review of peer-reviewed studies on multilingualism in autistic children and its impact on children's language and communication skills. Following Preferred…

Children with disabilities and developmental delays (DD) often face challenges within education systems, which are typically unprepared to meet their language needs nor equipped to support bilingualism because of the current early intervention (EI) workforce. Given this, the five-language domains framework can help bilingual EI educators to…

Purpose: We investigated four theoretically based latent variable models of word learning in young school-age children. Method: One hundred sixty-seven English-speaking second graders with typical development from three U.S. states participated. They completed five different tasks designed to assess children's creation, storage, retrieval, and…

How to help babies and young children right from birth to become competent in talking as well as emergent literacy is illustrated by research findings as well as with specific clinical stories. Both kinds of knowledge can serve to galvanize parents and teachers to increase awareness of infant and preschool language development and the crucial role…

Purpose: The purpose of this study was to contribute to the current understanding of how children with specific language impairment (SLI) organize their mental lexicons. The study examined semantic and phonological priming in children with and without SLI. Method: Thirteen children (7;0-11;3 [years;months]) with SLI and 13 age-matched children…

Two experiments assessed whether 7-year-old children activate semantic information from sub-word orthography. Children made category decisions to visually-presented words, some of which contained an embedded word (e.g., "hip" in s"hip"). In Experiment 1 children were slower and less accurate to classify words if they contained an embedded word…

This chapter, to be included in "Carmichael's Manual of Child Psychology," edited by P.A. Mussen, deals with the connection between the acquisition of language and the growth of intellect, and the connection between both of these and the process of maturation. The author feels that various theories of development cannot account for the child's…

The study examined the influence of the semantic variable of contrastive gender of the pronoun, and the phonological variable of contrastive stress of the pronoun, on four- to eight-year-old children's comprehension of syntactic structures containing the nonidentity pronominal reference. Four types of items were generated: those containing…
