Children's understanding of passives of certain mental state predicates appears to lag behind passives of so-called actional predicates, an asymmetry that has posed a major empirical challenge for theories of passive acquisition. This paper argues against the dominant view in the literature that treats the predicate-based asymmetry as…

We investigated longitudinal relations among gaze following and face scanning in infancy and later language development. At 12 months, infants watched videos of a woman describing an object while their passive viewing was measured with an eye-tracker. We examined the relation between infants' face scanning behavior and their tendency to follow the…

The world's languages draw on a common set of event components for their verb systems. Yet, these components are differentially distributed across languages. At what age do children begin to use language-specific patterns to narrow possible verb meanings? English-, Japanese-, and Spanish-speaking adults, toddlers, and preschoolers were shown…

We examined infants' recognition of functors and the accuracy of the representations that infants construct of the perceived word forms. Auditory stimuli were "Functor + Content Word" versus "Nonsense Functor + Content Word" sequences. Eight-, 11-, and 13-month-old infants heard both real functors and matched nonsense functors (prosodically…

Examined the role of animacy and pronouns as children ages 2 to 3 years acquired transitive construction. Participants learned two nonce verbs, one of which was modeled in several transitive sentence frames and the other in neutral sentence frames. Many children produced transitive sentences with the first verb, but only children near age 3…

This paper, based on naturalistic data, describes the acquisitional course and use of the articles "a" and "the" in young English-speaking children (18-61 months), with special emphasis on the role of individual variation. A growth modeling approach to the data reveals that children's individual acquisition schedules are similar in trend, but vary…

Speech discrimination by 12 children aged about 1 1/2 to 3 1/2 years was tested, using the discrimination learning procedure of Shvachkin's 1948 Russian study. Recent work on the acquisition of syntax and semantics shows an ordered acquisition for linguistic items; this pilot study was to test whether the ability to discriminate between consonants…

When speaking to young children just acquiring language, parents employ certain appropriate language features. Parental speech in English and Spanish was analyzed for presence and distribution of these features. Differences were noted, yet there was a high degree of similarity across parents and languages for frequently occuring features. (CHK)

Six experiments involving 192 infants and 1 experiment with 16 college students examined sensitivity to acoustic correlates of phrasal units in English. A basic finding is that nine-month-old infants are sensitive to acoustic markers that correspond to major phrasal units, a sensitivity that develops after six months. (SLD)

Investigation of the perception and production of English voiceless fricatives in normally developing monolingual 3- to 5-year-olds (N=12) partially supported the hypothesis that certain sound substitutions by older children are perceptually based substitutions, typified by poor discrimination, while others are phonetic substitutions--phonemic…

This volume deals with various aspects of the relationship between linguistic ability and general cognitive development. It presents original, up-to-date research for child psychologists, linguists, psycholinguists, scholars, teachers, and students interested in this field and interprets the findings in the context of contemporary linguistic…

This project began with a theory about the prediction of errors in childrens' attempts to pronounce utterances modeled for them by adults. Subjects were children from 15 to 54 months old in all positions in the family. The sample from each child was an unprompted utterance judged to be an attempt to say something in English. Differences between…

This original comparative study explores two central questions in the study of first language acquisition: What is the relative impact of structural and functional determinants? What is universal versus language-specific during development? The study addresses these questions in three domains of child language: reference to entities, the…

Research was conducted to examine the language acquisition of a Mexican-American child who has been brought up in a linguistic environment where code-switching between Spanish and English is the dominant style of speaking. In addition, the relation of code- switching to the acquisition of bilingualism is analyzed. The speech of the subject, a…

This collection of abstracts is part of a continuing series providing information on recent doctoral dissertations. The 17 titles deal with the following topics: oral language characteristics of college freshmen; the language development of a modern day "wild child"; children's understanding of relational terms; the relationship of…
