Generative approaches to language have long recognized the natural link between theories of knowledge representation and theories of knowledge acquisition. The basic idea is that the knowledge representations provided by Universal Grammar enable children to acquire language as reliably as they do because these representations highlight the…

This study investigates the acquisition of word-initial Korean obstruents (i.e. stops, affricates and fricatives). Korean obstruents are characterized by a three-way contrast among stops and affricates (i.e. fortis, aspirated and lenis) and a two-way fricative contrast (i.e. fortis and lenis). All these obstruents are voiceless word-initially.…

This paper reports the results of a longitudinal case study examining the acquisition of the English voice system by a three-year-old native speaker of Dutch. The study aims to examine whether the child develops two different phonetic systems or uses just one system for both languages, and compares the early L2 acquisition process with L1,…

The study investigates the development of English multiword negation, in particular the negation of zero marked verbs (e.g. "no sleep", "not see", "can't reach") from a usage-based perspective. The data was taken from a dense database consisting of the speech of an English-speaking child (Brian) aged 2;3-3;4 (MLU 2.05-3.1) and his mother. The…

The progression through the developmental stages of the acquisition of interrogatives was analyzed. Data on use of the "what" interrogative were collected during play sessions from eight children at six-month intervals from the ages of 1;6 to 3 years. More than 2,400 children's interrogatives were recorded. It was demonstrated that…

A study of the awareness of verb transitivity in the spontaneous speech of two two-year-old native speakers of Quiche was accomplished by examining three factors: transitive terminations given to verbs, subject markers on the verbs, and syntax. The first was studied by counting the number of transitive verbs used with both transitive and…

A study analyzed three episodes of self-repetition in a 1-year-old's utterances and examined the child's use of self-repetition for exploiting and elaborating on his phonological system in the context of discourse. The subject was a first-born monolingual child in the Stanford Child Phonology project. The analysis provides clues about how the…

As Peters (2001) has suggested, the young child's use of fillers seems to indicate awareness of distributionally-defined slots in which some as yet unidentified material belongs. One may view a filler as an emergent transitional form; as a slot that serves as an underspecified lexical entry for the accumulation of phonological and functional…

The treatment of a 10-year-old elective mute boy is reported in detail. A learning principles based approach was used in a one-to-one therapeutic setting. Relatively normal speaking patterns were established after 15 months of treatment. (Author)

A case study of the acquisition of Hausa as the first language by a child focuses on acquisition of interrogatives. The subject was a male child aged 25-60 months. Data were drawn from observation and elicitation. Three phases of acquisition were distinguished. Strategies adopted by the child appeared to reflect realities and contacts in his daily…

A case study was undertaken to examine the influence of one aspect of signed grammar, transparency of reference of some signs, on the acquisition of possessive pronouns in American Sign Language (ASL). The subject was a hearing child of deaf parents who was learning ASL and English. Data were collected in home visits betwen the ages of 1.1 and 3.2…

A study examined the role of phonological regression in the language learning patterns of two toddlers. The children's phonological development was measured by inventories of the words produced at the beginning and end of an eight-week period, and distinctions were made between regressions due to cognitive factors and those due to non-cognitive…

A study examined the teaching and learning processes in the mother-child interaction that lead to the child's acquisition of the English morphemes for future and past. Data were drawn from transcripts of a mother and daughter's interaction during a period of active acquisition, age 22 to 27 months. Longitudinal microanalytic and macroanalytic…

An interactionist-discovery theory of child phonology is proposed based on the following tenets: children invent their own phonological rules, and phonetic mastery is not automatically or generally in step with learning about phonemic contrasts. When a child learns the sound pattern of a language, there is constant interaction between the…

A discussion of language acquisition assumes that lexicon plays a central role, and that the principles of conventionality and contrast are also essential. It examines the hypotheses children draw on about possible word meanings and how they map their meanings into forms. This process begins with children's emerging knowledge of conventional words…
