Abstract
The overlap of numerical and non-numerical properties in concrete object arrays raises the questions of how these input dimensions interact, and how this interaction affects numerical cognition. Two studies were conducted to address these questions and showed that changing the object identity (while retaining the numerosity) and changing the numerosity (while retaining the object identity) both resulted in attenuated recognition of the unchanged dimension. However, this interference differed across development. In the adults and older children interference was asymmetrical (i.e. changing the object identity has greater effect on memory for numerosity than changing the numerosity had on object identity). In contrast, the young children showed a symmetrical pattern of interference. These results imply that people may not process numerosity of sets independently from non-numerical surrounding properties; rather, they integrate all of the visual properties present in the stimulus and use them even when the integrated inputs were not relevant to a task. Furthermore, independent processing of numerosity would be utilized only with focused attention later in development.
