Abstract
In this chapter, the authors propose neural reuse as a promising unifying framework for the advance of developmental cognitive neuroscience. In order to do so, first, the authors describe the hypothesis of neural reuse and some of the evidence for its importance to and impact on the development of the brain. Then, the authors compare neural reuse with the three prominent frameworks in contemporary developmental cognitive neuroscience—maturational viewpoint, interactive specialization, and skill learning—and show how neural reuse can accommodate their virtues while avoiding their shortcomings. After that, the authors explore some of the implications of neural reuse for the developmental study of math cognition, brain dynamics, and neurodevelopmental disorders. Finally, the authors sketch some future directions of research and some specific research suggestions.
