One of the fundamental questions in the field of language acquisition is a learnability problem, which considers how learners acquire certain aspects of language which are not directly provided in the input or whose referents are not readily observable. This dissertation investigates Japanese children's acquisition of various linguistic phenomena,…

The present study investigated children's early use of verb inflection in Japanese by comparing a generativist account, which predicts that the past tense will have a special default-like status for the child during the early stages, with a constructivist input-driven account, which assumes that children's acquisition and use of inflectional forms…

This study investigates the emergence and development of the discourse-pragmatic functions of the Japanese subject markers "wa" and "ga" from a usage-based perspective (Tomasello, 2000). The use of each marker in longitudinal speech data for four Japanese children from 1;0 to 3;1 and their parents available in the CHILDES…

This year's conference theme, "Be Seen, Be Heard," reflected not only our goal of celebrating our achievements but also represented our intent of making sure everyone's voices are heard, especially during 2017's difficult political climate. The conference opened with a motivating address from Dean Laura E. Lyons, followed by an…

While acquisition of more than one language from birth is a relatively common phenomenon, whether children under two years of age use their languages in a differentiated manner has not yet been established. The current study investigates the pragmatic differentiation of a child who lives in Australia and was acquiring two minority languages,…

Compares use of first person singular and second person singular references in Japanese and American children six years old and under. Hypothesizes that Japanese children use a greater variety of these forms and observe sex distinction in the use of these forms to a greater extent than American children. (Author/AM)

Although intonation has been said to be one of the first meaningful units of language that a child acquires, it is difficult to say just what this really means. How does the child learn to distinguish the various grammatical meanings that an intonation can have? It was hypothesized that the child first acquires question and request forms on the…

A study of data on Japanese children shows that the development of verbs occurs at the same time as the development of nouns and may even precede it. The subjects for the study were two children who were learning Japanese as their first language. Four speech samples, taken between the ages of 22 and 28 months, were audiotaped and supplemented by…

The frequency with which a child's parents use a given linguistic form has been considered influential in language development. This hypothesis has been challenged, however, notably by Ervin (1964) and Brown (1973). The frequency hypothesis makes the assumptions that: (1) children are not selective in what they attend to, (2) they listen to most…

Presents a psycholinguistic analysis of young children's performance in Japanese before, during, and after a two-month stay in Japan from the perspective of Vygotsky and the Soviet school of psycholinguistics. Looks at the social function of their utterances, the types of regulation involved, and strategic functions that may be intended. (SED)

Investigation of use of stative, process, punctual, and non-punctual verbs by a child acquiring Japanese as a first language found that sampled present progressive verb forms occurred with process verbs while these forms were never used with stative verbs. Most omissions of present progressive forms occurred with the early use of "mixed"…

Reports on an eight month study examining the development of turn-allocation devices in children acquiring English as a second language. The role of prior language experience in second language learning is explored. (Author/AM)

A naturalistic study looked at the acquisition of English by two Japanese boys, aged 4 and 8 years, during a 2.5-year stay in the United States. Data were collected through observation and transcription of spontaneous speech in daily life. Analysis included a variety of features of language use and of the acquisition process, including attitudes…
