The basis for acquisition of categories in child language was investigated. The early encoding of the distinction between mass and count nouns was examined to determine whether children categorize them on the basis of semantic type or syntactic regularities. An experiment was designed in which semantic and syntactic cues were in competition:…

Language samples were gathered from two children, from several weeks after the first birthday of each child to the beginning of the child's two-word period (approximately 10 months). The children were observed and videotaped every two weeks, to obtain 33 continuous minutes of tape. Analyses focused on the question of whether or not the child uses…

A set of six conditions for critically analyzing proposals in the various areas of language acquisition is developed and justified. These conditions are then applied to theoretical proposals in language acquisition literature. Proposals in the following areas are discussed and evaluated: (1) phonological development, (2) early lexical development,…

This discussion argues that the development of children's definitions is shaped by a particular orientation to word meaning characteristic of literate language use. This orientation is marked by increased attention to the linguistic form of expressions. To test this argument, a study was undertaken in which eight common nouns, familiar to most…

This study focuses on meaning differentiation among different causative expressions. Semantic differences between lexical and periphrastic expressions are reviewed. A picture comprehension task was administered to 32 adults and 99 children between the ages of 32 and 70 months. The children were asked to select the picture that matched a sentence…

A distinction is drawn between pragmatic and semantic meaning and a supporting discussion is presented. The hypothesis is then stated, that there are cases where semantic meaning of an utterance is learned as an abstraction from pragmatic meaning. Data from two experiments on a group of 63 preschool children are presented which provide empirical…

Examines preschool children's comprehension of the differing implications of the verbs "think" and "know". Results indicated that 4-year-olds, but not 3-year-olds, understood the differences between the terms. (JMB)

Considers children's understanding and use of contrast in language, including discussion of the role contrast plays in adult speech, the kinds of contrast commonly exemplified, and possible tests for sameness or difference of meaning. (CB)

Examines the age at which and the form in which children produce speech acts which commit them to a future action. Results revealed that all of the four- to 11-year-olds produced directive speech acts, but only the older children used the explicit performative verb "promise" to reassure the hearer of their commitment. (Author/CB)

Examines the relationship between children's attribute saliency and metaphor interpretation. Findings indicate that attribute saliency for the individual perceiving the metaphor plays a key role in the interpretation process. (Author/CB)

Children were asked to judge/correct sentences in which verb pairs, as predicates, could be associated with propositions or "arguments" which were obligatory for one verb and optional for the other. Results indicated gradual progression with age from initial ignorance to adultlike representation of obligatory and optional arguments for each verb.…

Reports on research that sought to clarify Brown's (1973) research on acquisition order, syntactic complexity, semantic complexity, and the relationship among the three. (Author/AM)

Reports on an experiment, performed on seven children, designed to show that children understand "here" and "there" with the self as reference point before they understand words such as these with reference to other speakers as reference points. (Author/AM)

Presents examples of how children acquire language through the principles-and-parameters model, a highly modular system in which different theories interact so that only permissible sequences arise, and highlights research on Spanish syntax and semantics. (136 references) (CB)

A case study on bilingual child language development used the systemic functional (SF) model to analyze data. Other studies have used the generative transformational or pragmatic models. The SF framework recognizes language as a tristratal system composed of semantics, lexicogrammar, and phonology. (49 references) (LET)
