With reference to Fenson's (1984) study of American children's pretend actions and utterances, this study examined the development of pretend actions and utterances in the play of 16 Japanese firstborn children. Subjects, whose cognitive and language development had been followed experimentally since the age of 6 months, were nonretarded…

A line of reasoning used in recent research on language acquisition assumes that a child acquiring the language has only two reliable sources of information available about the target grammar: a set of grammatical principles and the primary data of the language spoken around him. A third kind of evidence, negative evidence, would be helpful but is…

A study of the phonetic changes occurring when a speaker attempts to revise an unclear word for a listener focuses on changes made in the sound segment duration to maximize differences between phonemes. In the study, five-year-olds were asked by adults to revise words differing in voicing of initial and final stop consonants; a control group of…

A study investigated children's hypotheses about the meanings of novel verbs on the child's first exposure to the verb. The study focused on the properties (action, result, or instrument) ascribed to the verbs before any information was given about word meaning. Subjects were 3-year-olds, 5-year-olds, and adults. The stimuli were six sets of…

Children's ability to learn aspects of their language in the absence of supportive evidence is discussed. Specifically, the learnability of null subjects in languages in which they appear is examined when indirect negative evidence is present. It is concluded that parameters such as the null subject parameter may not generate languages, strictly…

This paper examines the referential strategies used by Japanese children and adults in two story telling tasks focusing upon the following discourse contexts: (1) first mentions of story characters, (2) references in subject position to the same character, and (3) references to another character. The subjects, 60 children and 10 adults, were…

Three experiments were conducted to conceptualize how structural differences between English and Japanese affect the way in which young children acquire the verification system. Linguistic characteristics that may distinguish between English and Japanese verifications are described along with the possible responses to four types of statement: true…

Confirms previous studies showing the existence of implicit phonological rules in children and the extent to which the rules govern the behavior of speakers of English. (RB)

A sequence of behaviorally specified drama skills needs to be developed--but cautiously. (JH)

Two studies were conducted, with three-to-five-year-olds, to assess the relationship between language comprehension and production and the development of quantity concepts. The asymmetry of acquisition of adjectives, "big" and "little," was also assessed, as well as differences in the acquisition of the underlying concepts. In Experiment 1, it was…

Three experiments with children between 5 and 7 years are described. It is shown that nominal predication of an unknown word by a superordinate term enables young children to make appropriate inferences concerning its attributes. The results are discussed in relation to semantic development and reasoning in the young child. (Author/RM)

A teacher of elementary school students and father of preschool age children admits his errors and misconceptions concerning child rearing, discusses what he has learned from his children's communicative behavior, and offers suggestions to parents for promoting the growth of children's expressive abilities. (Author/RH)

The speech of 18 children aged 4;1 to 7;1 during role-playing sessions simulating family, doctor, and classroom situations was analyzed for the use of directives. Six categories of directive formula types were identified, and the use of each of these in each context was examined with a view to determining the child's sense of what directive is…

Children and adults participated in two speech perception experiments in which they listened to recorded consonant-vowel-consonant (CVC) words in random order and resPonded by indicating which number of a word-pair they had heard. Some but not all stimuli that were intended to induce perceptual cross-over were successful in getting subjects to…

This paper argues that if conclusions about children's grasp of logical concepts are to be reached and acceptable lines of research followed, then more precise definitions of the concept "logical necessity" must be formulated. The paper defines logical necessity as "the unconditional guarantee of truth that accompanies valid…
