This article explores relationships between designing and making in the work of children within the age range 5-11 when engaged in practical modelling tasks. The notion of the model is explored from the perspective of concrete representations. It is suggested that concrete models may be used as hypotheses from which to test ideas about the nature…

The purpose of this study was to determine what effect exposure to linguistic input pertinent to kinship terms and kinship relations has on the acquisition of the meaning of such terms. The subjects were 84 German children living in families, and 84 orphans. (Author/CFM)

This paper examines whether language development can be understood epigenetically in the same manner and based on the same principles with which Piaget has analyzed intellectual-cognitive development generally. The study is subdivided into four parts: (1) some principles in Piaget's system (the epigenetic principle, the genetic circle, and the…

Examines whether young children make explicit references to beliefs, ideas, thoughts, and intentions. Relates that three-year-old children correctly distinguish between real and mental items and that they think and dream about things that are not real. Concludes that conceptual development theories portraying early development as concrete and…

Two semantic theories of word learning, a perceptual complexity hypothesis (H. Clark, 1970) and a quantitative complexity hypothesis (E. Clark, 1972) were tested by teaching 24 preschoolers and 16 college students CVC labels for five polar spatial adjective concepts having single word representations in English, and for three having no direct…

Focusing on the acquisition of semantic features and the relation between semantic and perceptual features, this study further tests the "semantic feature hypothesis," where a child acquires full adult word meaning component by component, and its complementary "correlation hypothesis," which claims that the source of these semantic features lies…

The purpose of this research was to develop methods to study the effects of context on children's comprehension and production of temporal terms such as "before,""after,""next,""then," and "but first." A longitudinal study, using naturalistic and traditional laboratory methods, and three…

Twenty-four children aged five and twenty-four children aged six were interviewed individually three times during a calendar year. It was found that not only did the children's language develop over the period, as judged syntactically and lexically, but they also showed an increasingly fluent control over their own style. All the children…
