Background:

Superordinate categorization relies on abstract relations, not just appearance.
Operativity, the ability to form nonfigurative relations, is key to this categorization.
Understanding how children develop superordinate categorization is crucial for developmental psychology.

Purpose of the Study:

To assess the role of cognitive development in superordinate categorization.
To compare categorization strategies between preoperational and concrete-operational first graders.
To investigate how children utilize and acquire superordinate knowledge.

Main Methods:

Employed two categorization tasks (Category-Membership and Sample-Match) using color drawings of artifact exemplars.
Assessed age-equivalent preoperational and concrete-operational groups of first graders.
Analyzed consistency in categorization decisions based on cognitive level.

Main Results:

Both cognitive groups showed similar category membership decisions.
Concrete-operational children consistently matched exemplars if they belonged to the same category.
Preoperational children additionally required exemplars to be typical for matching, indicating a reliance on figurative cues.

Conclusions:

Cognitive level influences the strategy for matching exemplars within superordinate categories.
Preoperational children's reliance on typicality highlights developmental differences in overcoming figurative similarity.
Findings contribute to understanding the acquisition and utilization of abstract knowledge in children.
