An investigation of children's metalinguistic and metacognitive competencies examined children's sensitivity to the verbs of cognition in two related studies using a task designed to measure mastery of verbs of saying and meaning. In the task the children hear six short stories, each ending with a statement containing one of the verbs…

Two markedness hypotheses in current language acquisition theory are examined. One view of markedness, the developmental hypothesis, states that the unmarked case is the child's initial hypothesis, i.e., the hypothesis that is set in advance of linguistic data. The developmental hypothesis further predicts that children will proceed in a fixed…

A study examined repair sequences in talk between two German-English bilingual children and between parent and child within a nuclear family in which German is generally spoken. Data were drawn from tape recordings and developmental diaries kept on the two preschool children. Patterns of parent-child and child-child corrections were examined. In…

A study examined 12 preschool children's early use of "who,""what," and "which" questions in spontaneous speech. Results indicated that children began to ask object questions before they asked subject questions, and acquired argument questions before adjunct questions. It was suggested that the two results could…

A case study of a 2-year-old progressing normally in speech development provides evidence of suprasegmental marking of the plural, thought to be adopted only in language-impaired children. Acoustic analyses of the durations and intensity of elicited words indicate that the child had adopted a suprasegmental strategy for marking the singular/plural…

The question of why language acquisition is not instantaneous is addressed in terms of two related issues: the logical and the developmental aspects of language acquisition. The role of linguistic theory and research in determining the interplay of these two aspects of grammatical development is examined. It is suggested that the…

Relationships between "combinatorial" abilities in language, symbolic play, blockbuilding, and non-semantic action sequences were explored in a study of 30 infants between 82 and 91 weeks of age. Subjects were observed in a laboratory playroom setting for approximately 45 minutes. During this time, a number of tasks were administered…

Three experiments on the comprehension and acquisition of temporal terms are described. Methodological innovations were applied to control for possible methodological effects on children's performance. Each experiment involved 24 children aged 3 to 5. In the first experiment, subjects manipulated toys in response to instructions containing the…

The emergence of the ability to maintain and develop a topic of conversation is examined. The production of a competently structured topic involves utterances that are both propositionally contingent on previous utterances and related to the global concern of the topic. Children under 2 years of age can only product utterances that are…

The use of imitation as a language learning strategy was explored in a case study of a child in a Mandarin-speaking family. Recordings were made over the course of 3 months, from the ages of 2 years 10 months to 3 years 1 month. It is argued that restrictive criteria regarding identity of form and temporal proximity of utterances have severely…

The acoustic features and functions of accentuation in French are discussed, and features of accentuation in the speech of French 2-year-olds are explored. The four major acoustic features used to signal accentual distinctions are fundamental frequency of voicing, duration of segments and syllables, intensity of segments and syllables, and…

A study of the late acquisition of the passive in Zulu used data from transcripts of naturalistic speech gathered in a longitudinal study of several children's speech development between 1.10 and 3.6 years of age. It was hypothesized that the productivity of the passive construction in Zulu is a factor facilitating acquisition. A range of…

Two studies examined the development of major properties of reflexives and pronouns in English language acquisition by applying the theory of binding of reflexives and pronouns to potential antecedents in the sentence. The children ranged in age from 2.6 to 6.6 years. In the first experiment, the children were presented with two pictures and were…

An experiment was undertaken with young children to look at the relative contribution of discourse constraints, subject anaphors, and the semantics of verbs to the integration of an utterance into its discourse representation. Children aged 5, 7, and 10 years heard a series of short stories, each consisting of three sentences and an incomplete…

A study of the acquisition of time-related grammatical forms in Hebrew-speaking children looked at three kinds of information: (1) relative frequency of occurrence of different verb forms at different ages; (2) the relationship between tense-marking on verbs and the semantics of verbs used at different ages, and (3) the use of time adverbs…
