Three studies examined the domain of concepts about dinosaurs in order to assess how the domain might be structured in 4- through 7-year-old children's representations and to explore how the knowledge might be used. Findings indicated that significant differences exist in the way expert and novice children's representations are structured.…

A multidimensional model of the growth of moral reasoning is described that is significantly different from those proposed by Kohlberg and Piaget. A study that tests several aspects of the model on university students is reported. The suggestion that well-developed chains of reasons are a prerequisite for the emergence of metaethical reasoning was…

This paper contains an elementary and short proof for the case that the underlying distribution function F is discrete, and then extends the result to the general F. In other proofs underlying iid sequences of random variables with continuous distributions are considered to be the "ideal" case. In this paper discretization of the underlying iid…

Literature on cognition is surveyed with a special emphasis on the development of academic skills in handicapped children. (Author/KM)

Tested 63 kindergarten children on a spatial perspective task in which they copied the location and orientation of objects when the model and response spaces were aligned or when one was rotated 90 degrees or 180 degrees. (LLK)

Examines the concepts employed by normal and retarded children matched for mental age in kindergarten through fourth grades. Two studies explored the schema by which these children organized their experience into meaningful patterns. (LLK)

This study investigated the development of the concept of a critical search area by means of an action sequence in which a cartoon character loses his toy while walking through his house. The results showed that it is not until ages 7 or 8 that children readily make the inference that the critical area is the only plausible place to search for the…

This study investigated the use of covariation as a principle of causal analysis in children 3-4, 6-7, and 9-11 years of age. The results indicated that children as young as 3 years were capable of using covariation information in their attributions of simple physical effects. (Author/CS)

The patterning of recall of linguistic subunits was found to be strongly related to the semantic dimensions of abstractness-concreteness, specificity of denotation, comprehensibility, and interest. (Author/BJG)

Twenty children, 3-12 years old, were given a newly constructed interview on their concepts of human reproduction (social causality), in conjunction with Piaget-type tasks assessing physical conservation-identity, physical causality, and a new social identity task. The children's concepts of human reproduction appeared to proceed through a…

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)

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…
