Brief Summary:
It is commonly believed that objects in the world can be categorized in at least three different ways or levels The three levels are basic superordinate and subordinate Previously it was believed that basic categorization presents a cognitive mental advantage to childrens development However recent studies on superordinate categorization has challenged this belief
1 TABItems in superordinate are grouped according to functional purpose even though they may not share any similarities in how they look perception For instance desks chairs and beds do not appear similar but they can be group together in the superordinate category of furniture
2 TABItems in basic categorization share similarities in function and in perception For instance chairs can be considered as a basic category Chairs can share functional and perceptual similarities with many kinds of chairs but are readily distinguished from other types of furniture like beds or desks
3 TABSubordinate categories are subsets of basic categories For instance kitchen chairs desk chairs and high chairs are all within the basic category of chairs Each one is very similar in its function to the others but is definitely discriminable
This study was developed to investigate the development of categorization at all three levels by using a design in which children between the ages of 1 and 3 years are tested for categorization at all three levels with sets of objects from the same domain such as vehicle or fruit Researchers plan to chart when infants develop categorization at the basic subordinate and superordinate levels over the two-year periodTAB

Detailed Description:
The major objective of this research is to better understand the functional significance of object categorization in early development The proposed work is designed to examine the emergence of organization in toddlers internal representations of real-world categories such as furniture and fruit Representation in this capacity refers simply to stored information that can influence later behavior Categorization refers to the treatment of discriminable as equivalent in some way
Even young infants appear capable of categorizing diverse sets of discriminable patterns and objects and can form internal representations of such bounded collections Much less is known however about changes leading from this basic capacity to the highly structured concepts that are characteristics of children s and adults category knowledge The present research is designed to characterize the course of these changes between infancy and childhood
The primary research strategy to be used consists of analyzing toddlers examination and manipulation of familiar objects that are similar within adult-defined categories than between such categories The organization and temporal structure of children s actions on the objects will be coded and analyzed to infer the similarity relations that are perceived among of each stimulus set
