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…

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…

Parent report instruments adapted from the MacArthur-Bates Communicative Development Inventories (CDI) examined vocabulary development in children aged 0 ; 8 to 2 ; 6 for two Chinese languages, Mandarin (n = 1694) and Cantonese (n = 1625). Parental reports suggested higher overall scores for Mandarin- than for Cantonese-speaking children from…

Two nonce-word studies examined German-speaking children's productivity with the "Perfekt" (present perfect) from 2;6 to 3;6. The German "Perfekt" consists of the past participle of the main verb and an inflected form of an auxiliary (either "haben" "have" or "sein" "be"). In Study 1, nonce verbs were either introduced in the infinitival form, and…

Describes a study to determine: (1) the relationship between age and mean length of utterance measured in morphemes (MLU) in a group of normally developing two- and three-year-old chidren; (2) the standard error of MLU; (3) the relationship between MLU and age; and, (4) the ability of MLU to predict children's grammatical development.

Infants' phonological acquisition during the first 18 months of life has been studied within experimental psychology for some 30 years. Current research themes include statistical learning mechanisms, early lexical development, and models of phonetic category perception. So far, linguistic theories have hardly been taken into account. These…

The claim that children's early word combinations are best described in terms of semantic categories such as agent, rather than abstract categories such as subject, rests on the assumption that 2-year-olds have a notion of agency that acts as a springboard for knowledge of more formal categories. The literature of developmental psychology suggests…

The role that talk plays in socialization, social development, and possibly cognitive development is described. Research on talk is categorized as follows: studies that consider talk as a tool for investigation; studies that focus on development of grammar or language acquisition; and studies that fall between those extremes. (LB)

A fundamental problem in language acquisition is determining how children learn the formal vocabulary of the adult grammar. A proposed solution is the Semantic Bootstrapping Hypothesis (SBH), which states that children infer the identity of syntactic entities such as "subject" in input based on the presence of semantic entities such as…

This volume deals with various aspects of the relationship between linguistic ability and general cognitive development. It presents original, up-to-date research for child psychologists, linguists, psycholinguists, scholars, teachers, and students interested in this field and interprets the findings in the context of contemporary linguistic…

Empirical evidence is presented in favor of a theory that attributes the delay in the acquisition of the passive to young children's ability to accomplish nonlocal assignment of features. Two experiments testing monolingual Spanish-speaking children's knowledge of the passive are discussed and analyzed in light of the theory of Argument-chain…

This collection of abstracts is part of a continuing series providing information on recent doctoral dissertations. The 17 titles deal with the following topics: oral language characteristics of college freshmen; the language development of a modern day "wild child"; children's understanding of relational terms; the relationship of…

This is the final report of the project entitled "A Study to Determine the Degree of Relationship between Linguistic Concepts and Structures in French as a Mother Tongue and Stages of Psychological Readiness of Students at the Junior and Intermediate Levels." The project's primary aim was to determine the psychological readiness, with…

The collection of papers on language development and African-American children includes: "The Challenges of Conducting Language Research with African American Children" (Holly K. Craig); "Issues in Recruiting African American Participants for Research" (Joyce L. Harris); "Issues in Assessing the Language Abilities of…
