Preschool and kindergarten nonconservers (N=114) were examined for their use of dimensions relevant to quantity in two conservation-of-substance tasks. The results were interpreted as being counter to Piaget's 4-step equilibration model of the development of compensation and conservation. (ST)

Two studies examined how nonconservers use the dimensions relevant to quantity in the conservation of substance task. Most nonconservers are very selective in their use of the information provided by these dimensions. Most preschool and kindergarten nonconservers used length to define amount, while ignoring width. This was true regardless of how…

A total of 174 first, second, and third graders were tested to examine the relation between perceptual salience and cognitive style. The results indicated that implusives made more errors than reflectives only on trials requiring the use of the least salient dimension and that these performance differences decreased with age.

Study explores the preschool child's ability to operate on a cognitive level by testing his capacity to compare a concrete stimulus with some abstract concept. (Author/CB)

This study compared the use of discrete and relational aspects of visual configurations in making similarity judgments. Subjects were 3-, 4-, 5-, and 8-year-old children and adults. (BD)

This study investigates the developmental changes that occur in the attending behavior of children engaged in a relatively simple classification task, and attempts to reaffirm the existence of developmental changes in stimulus preferences and in the ability to employ double classification systems. Subjects were 24 preschool and 24 first grade…

Uses the transposition paradigm to compare the influence of the adjectives "same" and "different" on the test choice of 5- and 9-year-old children. (Author/SDH)

To investigate two measures which have been used to assess children's attention to stimulus dimensions, component selection, and dimension preference, both measures were administered to 38 3 1/2 to 5-year-olds and 20 5- to 6 1/2-year-olds. Seven to ten days after the dimension preference task was given. the component selection measure was…

This exploratory study was conducted to interpret age and individual differences in 48 kindergarteners' and second graders' performance on a referential communication task in light of the Pascual-Leone Theory of Constructive Operations, a neo-Piagetian theory of cognitive development. Stimulus materials were black and white photographs of dogs,…

This paper examines the concept of decalage from two cognitive-change positions (structures of logical thought and attentional and verbal mediators) and proposes an alternative explanation for decalage from a perceptual-change point of view. The term decalage is used to summarize the relation between differences in performance of various age…
