Abstract

Categorization constitutes the most important function of information’s semantic organization in the memory system. Semantic organization refers to the way in which a person organizes the knowledge making sense of the world, while it also constitutes a vital part of language acquisition. One of the basic roles of categorization is to provide the cognitive system with high efficiency, whenever it encounters a vast amount of information in the environment. The aim of this study was to investigate types of categorization, and more specifically taxonomic and thematic pairings from preschool years to adulthood, using a cross-sectional design. One hundred and fifty (N =150) participants from five different age groups (3-years old, 6-years old, 9 years old, 13 years-old and 20 years-old) participated in the study. A categorization task was administered to all the participants. Each participant was presented with a target item and three other associate items (thematic, taxonomic and irrelevant). Then, he/she was asked to choose the one that «went best with the target item» and to justify the pairings. According to the results, the younger participants tended to create groups of items according to thematic associations, while older participants created groups of items on a taxonomic basis. Additionally, the type of justifications varied by age. Younger participants did not provide any justification or if they did, it was a thematic justification, while older participants used mainly taxonomic justifications.
