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…

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 IS THE FIRST MAJOR SECTION OF A CHAPTER PREPARED FOR "THE MANUAL OF CHILD PSYCHOLOGY," P.H. MUSSEN, EDITOR, IN PREPARATION. IT IS AN INTRODUCTION TO TRANSFORMATIONAL GRAMMAR WRITTEN FOR PSYCHOLOGISTS AND PRESENTS SOME OF THE MAJOR IDEAS THAT HAVE BEEN DEVELOPED IN MODERN LINGUISTIC THEORY, ALONG WITH CERTAIN OF THEIR PSYCHOLOGICAL…

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…

THE AUTHOR FEELS THAT TO APPROACH CHILD LANGUAGE TRANSFORMATIONALLY IS TO USE A TECHNIQUE SUITED TO PROVIDING ADDITIONAL INSIGHT INTO A WELL-KNOWN LANGUAGE FOR TREATING AN UNKNOWN, OR AT BEST LITTLE KNOWN LANGUAGE. SHE MAKES THE FOLLOWING CRITICISMS OF TRANSFORMATIONAL ANALYSIS OF CHILD LANGUAGE--(1) NOTHING CAN BE DIRECTLY INFERRED WITH REGARD TO…

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)

An alternative to the standard "rule based" account of a child's acquisition of the past tense in English is presented in this paper. While the rule based assumption suggests that children typically pass through a three-phase acquisition process in which they first learn past tense by rote, then learn the past tense rule and overregularize, and…

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…
