There is evidence for developmental hierarchies in the type of information to which infants attend when reasoning about objects. Investigators have questioned the origin of these hierarchies and how infants come to identify new sources of information when reasoning about objects. The goal of the present experiments was to shed light on this debate…

Three studies examined the developmental relationship between early linguistic and cognitive achievements. Findings showed that children's ability to classify objects in a spatial or temporal order was independent of advances in productive vocabulary growth, suggesting that developments in categorization and naming depend on abilities in addition…

Noting that current research on childrens mathematical development does not adequately detail how toddlers represent small numbers and the role that number words play in the development of number understanding, this study used a combination of methods to examine mathematical development in one toddler. Underlying the study was an Integrated Model…

Two experiments examined toddlers' noun vocabularies and interpretations of names for solid and non-solid items. Results indicated that one side of the solidity-syntax-category organization mapping was favored. Seventeen- to 33-month olds do not systematically generalize names for solid things by shape similarity until they already know many…

Calls for a process-oriented approach to study of categorization in infancy. Maintains that further understanding of infant categorization and its changes with development requires a more direct assessment of infants' category formation. Argues that two research directions will enhance understanding of categorization: (1) contextual variations on…

This document is Part I of a two-part project whose goal was to identify the sequential development of child behavior from birth through age seven and to identify the materials which could be used to strengthen or initiate a behavioral facet. Research on child development was collected, organized, and analyzed for correlative events pertinent to…
