Object exploration is considered a driver of motor, cognitive, and social development. However, little is known about how early childhood education and care settings facilitate object exploration. This study examined if children's exploration of objects during free play was facilitated by the use of particular spatial components (floor, tables,…

Preschoolers made numerical comparisons between sets with varying degrees of shared surface similarity. When surface similarity was pitted against numerical equivalence (i.e., crossmapping), children made fewer number matches than when surface similarity was neutral (i.e, all sets contained the same objects). Only children who understood the…

To clarify the nature of the social cognitive skills involved in preschoolers' reenactment of actions on objects, we studied 31- and 41-month-old children's reenactment of intended acts (''failed attempts'') in Meltzoff's [Meltzoff, A. N. (1995)]. Understanding the intentions of others: Reenactment of intended acts by 18-month-old children.…

This study investigated the prediction that playful activity would increase the number of alternate uses that children would be able to give for objects which are not involved in that activity. Subjects were 36 white, middle-class preschoolers. (Author/SDH)

The purpose of this sequence of a working paper intended for inclusion in a curriculum manual to be published in the future, is to provide the child with concrete experience, opportunities to represent things symbolically, and to learn the nature of symbols and how to read them. Examining objects, acting them out, and experimenting with them, the…

Compared the impact of a small box emitting sounds in response to nearby motion introduced into an infant/toddler and a preschool classroom to illustrate qualitative differences in how children of different ages recognize the same objects as mediating devices for activity. Found that the box became a social object for infants/toddlers and part of…

Discussed are results of studies of the cognitive development of 2- and 3-year-old children which suggest that the mind makes gains in the ability to think as gains in language development are made. "Thinking" in this context refers to the judgments children made as they selected objects and maneuvered them into one arrangement or…

A dissertation proposal involved a study to observe spontaneous behavior of children in interaction with materials in order to gain understanding of the factors that influence classificatory and imaginative behavior in free play. Children at two levels of ability in terms of classification skills were observed in interaction with materials at two…

This paper reports on an experiment undertaken to delineate more clearly the relationship between the naming process in children and certain aspects of the environment which may play a role in that process. The investigation concerned the effect of manipulation and of object novelty on naming. Sixteen children, ten girls and six boys, ranging in…
