The association of locus of cerebral hemispheric specialization of spatial function with identity and equivalence conservation judgments was tested in a group of four- to six-year-old right-handed children (N=31). (Author/MP)

Employed regression analysis to determine the association between multiplicative classification and inductive reasoning. Subjects were 103 fourth grade children. (SDH)

One hundred and sixty first grade boys and girls of normal intelligence were tested for ability to conserve multiple space relations. The criterion task apparatus was a wooden T with a model of schoolhouse attached and centered above the point of contact of the horizontal and vertical axis. The T had a track running the length of both its axes…

It was shown that hierarchies change with development and that relative salience of a dimension is negatively associated with both reaction time of choice and number of errors on the identity task. (Authors)

In training people to perform auditory identification tasks (e.g., training students to identify sound characteristics in a sonar classification task), it is important to know whether or not training procedures are merely sustaining performance during training or whether they enhance learning of the task. Often an incorrect assumption is made that…

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…
