Two studies were conducted to discover possible patterns in question acquisition. For the production study, questions were collected from 22 children aged two to eleven. In the comprehension study, 100 children, aged three to five, were tested. The test controlled syntax and vocabulary and varied specific "wh-" question-words. (Author/RM)

Describes a study showing that mentally retarded children and mentally normal children do not differ fundamentally in cognitive development within the framework of a particular cognitive training. (Text is in French.) (AM)

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…

How a child answers questions provides information about how he or she processes input. A child's early responses to questions at age one year, three months, were compared to her responses at one year, seven months, when she was in the two-word stage. (SW)

A phenomenon called "pragmatic variation" is discussed as a child's individual system of behavior in response to a question the child doesn't understand but realizes that he must verbalize an answer to. (NCR)

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)

This experiment used two groups of preschoolers and one group of young grade-schoolers to test for their comprehension of presuppositions and negation in complex syntax. (NCR)

Observes 75 first- and third-grade children in their classroom mathematics seatwork to test assumptions drawn from Vygotsky's theory about the development of private speech and its relationship to task performance, attention, and motor behaviors accompanying task orientation. (HOD)

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…

A study was conducted to determine whether children give evidence of using any of six comprehension strategies and whether children of same and different ages use different strategies. It was studied how comprehension performance can best be predicted by other facts about the child, including his language and his language input. The six…

The role of language in conservation tasks and the development of the concept of conservation of quantity in young children are investigated in this study. A total of 50 children, aged 3.0 to 4.7 years, were divided into three groups according to age with a large number clustered around age 4.0 years. Children were randomly assigned to one of two…
