title: Understanding developmental changes in the stability and flexibility of spatial categories based on object relatedness.
abstract: Two experiments examined the flexibility and stability with which children and adults organize locations into categories on the basis of object relatedness. Seven-, 9-, and 11-year-olds and adults learned the locations of 20 objects belonging to 4 categories. Displacement patterns revealed that children and adults used object cues to organize the locations into groups. The organization remained the same following a 7-day delay for all 4 ages, demonstrating stability. Moreover, for 11-year-olds and adults, this organization shifted after a new pattern of object-location pairings was introduced. The pattern was less clear for the younger children, suggesting that flexibility increases across childhood. Discussion focuses on the dynamics of organization processes, particularly stability and flexibility, and the integration of objects and locations.
