When children succeed in changing their responses: Insights from three versions of a flexible categorization task

Cognitive flexibility is a hallmark of human cognition, but its development is still poorly understood. The present work examined the flexibility of categorization in preschool children. Thirty-three participants aged 3–4 years were divided into three groups, with each group receiving a different version of a flexible categorization task in which the targets belonged to two distinct categories. These versions manipulated the type of questions that were asked and the alternation of shape and color games. The children exhibited flexibility when the questions were specific (or asked about attributes). The results support the idea that instructions play a role in children’s performance in sorting tasks. Considering cognitive flexibility as an expression of the interaction between children’s knowledge and abilities on the one hand and the structure, specifics, or demands of the task on the other can help clarify what cognitive flexibility is and how it develops.
