Presents two models of language acquisition: one postulating articulatory learning of underlying adult forms and the other both articulatory and perceptual learning. Reanalyzes the first model's data and concludes that two types of phonological rules are recognizable: perceptual-encoding rules and output (articulatory) rules. Identifies properties…

Reports part of a continuing project to develop a theory of children's first-language acquisition using computer modeling techniques. Notes the correspondence of structures formed by the computer program with recognized structures in English. Discusses anomalies in the program's performance. (RL)

Sound-meaning correspondences produced by an infant were studied under conditions of early rampant homonymy (i.e., production by a very young child of a small set of noncontrastive surface forms or phonetic sequences to refer to objects/events that on the basis of adult standards require the production of numerous contrasting surface forms). The…

Data on the complexity of relative clause formation in children indicate that right embedding precedes central embedding in development. Previous research on the subject argues that configurations where coreferential NP's function as subjects are less complex than configurations where coreferential NP's function as objects. It appears that the…

Two experiments indicating that children's linguistic generalizational biases change from a semantically-based system to a syntactical-structural system provide evidence for a semantic-relational bias in children's early grammars and support the notion that children's generalizational biases shift from a semantic-relational basis to a…

Contrasts the syntactic view of forward and backward deletion of base structure elements with the idea that pragmatic factors of situational redundancy and perceptual grouping account for conjunction reduction in children. (EKN)

This report examines the question of whether grammatical rules are globally learned and applied. It also attempts to determine the underlying word order in English as well as the developmental sequence of the acquisition of Aux. A sentence-repetition test using positive statements, positive questions, and negative questions was administered to 30…

Studies analyzing children's response time to detect word targets revealed that six-year-olds and younger children generally did not show the response time advantage for accented target words which adult listeners show, providing support for the argument that the processing advantage for accented words reflects the semantic role of accent as an…

The development of production and comprehension by one two-year-old girl of three Japanese constructions (passives, causatives, and "te moraw"), which have similar surface configurations "NP ga NP ni V ("rare"/ "sase"/ "te moraw") TENSE," is investigated through elicited imitations and responses to the investigator's questions about the content of…

The acquisition of rules for formulating causative verbs was studied with children over a period of a few years. Most of the data is based on the spontaneous speech of the author's two daughters, from age 2;6 to 6;2 and from age 2;4 to 3;11. It was hypothesized that there are at least two prerequisites for the child's formulation of a general rule…

The question is addressed whether a child would develop a communication system if a conventional linguistic model is absent. Six congenitally deaf children, who were not exposed to Sign Language, were observed and videotaped at play in their homes at intervals of one to three months. The children ranged in age from 1 year, 5 months to 4 years, 1…

The parameter-setting model of universal grammar provides a basis for integrating two theories of second language acquisition: contrastive analysis and creative construction. The elicited responses of adult native speakers of Spanish and adult native speakers of Japanese were examined. The head-initial/head-final parameter was the principle…

This research report deals with the transformations of stimulus sentences that primary grade speakers of Hawaii Creole English (HCE) made when they were asked to repeat sentences said to them in Standard English. The test used was the Kamehameha Early Education Program (KEEP) Standard English Repetition Test (SERT) which was administered to the 21…
