This commentary critiques Ambridge's radical exemplar model of language acquisition using research from the Longitudinal Study of Early Language, which has tracked the language development of 30+ children with Autism Spectrum Disorders (ASD) since 2002. This research has demonstrated that the children's capacity for abstraction at the grammatical…

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…

Drawing on the findings of longitudinal studies in uninstructed contexts over the last two decades, this synthesis explores variations in developmental patterns across second language (L2) pragmatic features. Two synthesis questions were addressed: (a) What are the variations in developmental patterns across pragmatic features?, and (b) What are…

This dissertation explores parallels between Complementizer Phrase (CP) and Determiner Phrase (DP) semantics, syntax, and morphology--including similarities in case-assignment, subject-verb and possessor-possessum agreement, subject and possessor semantics, and overall syntactic structure--in first language acquisition. Applying theoretical…

The present article compares and contrasts linguistic findings from longitudinal studies of low-income Americans derived from evidence of recorded family speech interactions. Hart and Risley (1995) employed research assistants who spent 1 hour per month observing language usage among families from different socioeconomic backgrounds in their homes…

This study investigates prosodic (noun length) and lexical-semantic (animacy) influences on determiner use in the spontaneous speech of three children acquiring French, Austrian German and Dutch. In support of typological and language-specific hypotheses from the Germanic-Romance contrast, an advantage of monosyllabic nouns and of inanimate nouns…

Cross-linguistic research on the development of tense-aspect marking has revealed a strong effect of lexical aspect. But the degree of this effect varies across languages. Explanation for this universal tendency and language-specific variation is still an open issue. This study investigates the early emergence and subsequent development of four…

The aim of this article is two-fold: to test the Aspect Hypothesis, according to which the early use of tense-aspect morphology patterns by semantic/aspectual features of verbs, and Tense is initially defective (e.g. Antinucci and Miller, 1976; Bloom et al., 1980; Andersen and Shirai, 1994; 1996; Robison, 1995; Shirai and Andersen, 1995;…

Selected spontaneous errors of word choice made between the ages of two and five by two children whose language development had been followed longitudinally were analyzed for clues to semantic developmnet. (JMB)

Acquisition of negation in Italian as a second language (L2) is investigated on the basis of the longitudinal data of five learners with different first languages in the framework of a functional approach focusing on the semantic and pragmatic principles governing the organization of learner varieties and the process of their complexification.…

An overview is given of semantic research in adult Second Language Acquisition (SLA), focusing particular attention on undirected SLA. Several studies on child SLA are mentioned, and suggestions for further research on SLA semantics are offered. (35 references) (GLR)

Word learning by young children is viewed as a problem deriving from the use of forms of discourse texts. Uses of causal and temporal terms in private speech by a child studied longitudinally from 1;9 to 3;0 are analyzed from this perspective. (Contains 38 references.) (JL)

THIS 7-YEAR LONGITUDINAL STUDY OF THE LANGUAGE SKILLS OF 338 OAKLAND, CALIFORNIA, SCHOOL CHILDREN UTILIZES A SCIENTIFIC APPROACH TO THE STUDY OF BOTH THE SEMANTIC AND STRUCTURAL ASPECTS OF LANGUAGE. A SPECIFIC METHOD OF LANGUAGE ANALYSIS HAS BEEN SHAPED. THE "SEGMENTATION" METHOD OF ANALYSIS USES SEVERAL TYPES OF SENTENCE SEGMENTS. A…

Reports on an experiment describing the lexical development of a hearing child with a deaf mother and hearing father. Data confirm previous findings that (1) sign emerges before spoken word, (2) acquisition stages are similar in ASL and spoken English, and (3) the child initially develops one lexical system. (Author/AM)

Describes a research project in which the acquisition of French by two six-year-old boys, native speakers of English, was observed longitudinally. (CFM)
