Prototypicality and the Development of Categorization. Papers and Reports on Child Language Development, No. 16.
Mulford, Randa
Children aged three to five were the subjects of two studies of the development of ability to classify diverse objects into superordinate categories. In the first experiment, subjects were asked to designate two of three pictorially represented objects as representative of a given category. The second experiment required subjects to choose from a random array of objects those which fell within a given category. Results tend to support these hypotheses: (1) younger children recognize as category members a greater percentage of highly prototypical members than less prototypical members, (2) with increasing subject age, there is a decrease in the difference of percentages of high-prototypicality and low-prototypicality members correctly identified, and (3) the absolute percentage of correct identifications of category members increases with age for both high and low instances.
