Discusses a study that examines which combination of animate and inanimate actors (anyone or anything performing an action) and patients (the thing that is the object of action) two-year-olds view as prototypical. Results suggest that the actor category is usually acquired first for prototypical sentences with animate actors and inanimate…

Children's understanding of the nature of polar terms and comparative terms between the polar opposites is discussed. (CHK)

Diary observations of two-year-olds' over-extended word use have been interpreted as arising from the word's underlying semantic feature structure. This interpretation was rejected after a study of five children. The need to construct models of early word meaning reflecting certain early language development patterns is discussed. (CHK)

The comprehension ability of 36 children at three stages of telegraphic speech was assessed using active behavioral responses to declarative and imperative sentences. A significant increase in verbal and behavioral appropriateness with age was found for imperative and declarative forms. Results are compared with Shipley, Smith and Gleitman's…

In testing kindergartners and first graders in their comprehension of the words "before" and "after," it was found that when temporal terms are acquired, they are first used as prepositions and then as subordinating conjunctions. (Author/NCR)

Preschool children's comprehension of the adverbial modifiers "very" and "sort of" was experimentally investigated in 64 children. (Author/NCR)

A study was conducted to test whether three, four, and five-year-old children would be better able to use either static or dynamic properties for grouping objects, and whether performance under these conditions would be better than when no property was given. One of the two study tasks, the free sort, also used by Rosch et al. (1976), asked…

Comprehension of the quantifiers "some" and "all" was studied with 202 children, three to nine years old. Thirty-two quantifier sentences dealing with descriptions of circles and squares were presented to the children. Wooden objects were presented to some children to see if results were affected by the choice of abstract objects, but no…

Children's early utterances were studied to determine whether there are developmental changes in the content, context, frequency, and form of their speech and the degree to which the changes correspond to changes in Piagetian cognitive stage. Twenty children were studied; six were 10 or 11 months old, and the remaining 14 were distributed evenly…

The acquisition of rules for formulating causative verbs was studied with children over a period of a few years. Most of the data is based on the spontaneous speech of the author's two daughters, from age 2;6 to 6;2 and from age 2;4 to 3;11. It was hypothesized that there are at least two prerequisites for the child's formulation of a general rule…

A study was conducted to compare the relative performance on yes-no questions of bilingual and monolingual children and to discuss the relationship of semantic development and linguistic development, both in the bilinguals and monolinguals. Eighteen English monolingual, eighteen Japanese monolingual, and eighteen Japanese-English bilingual…
