The development of numerical abilities

The development of numerical abilities is crucial in our modern societies and constitute a critical foundation in order to acquire arithmetic and mathematical knowledge. One important stepping stone for the acquisition of numerical abilities is the construction of symbolic numerical knowledge: Children have to learn to represent numerical information via symbols, which can be number words or Arabic digits. In our research, we focus on how the brain constructs symbolic representations of numerical magnitude (i.e., knowledge about the number of objects) and numerical order (i.e., knowledge about the relative rank or position within a sequence) in children and adults.

Findings from our research has shown that the left intraparietal sulcus (IPS) of the parietal cortex is sensitive to the processing of numerical magnitudes and that this region shows a developmental specialization to represent symbolic information about numerical magnitudes. This brain specialization is characterized by an age-related increase in brain activity, which suggests an automatization of the left IPS to process symbolic numerical information as children get more experienced. Results from our work on numerical order has demonstrated that the understanding of numerical order (a) explains unique variance in children’s arithmetic abilities, (b) mediates the well-established association between numerical magnitude processing and arithmetic, and (c) shows specific neurocognitive developmental trajectories within the first years of formal education. More specifically, our recent neuroimaging work has demonstrated that the left IPS also shows an age-dependent increase in brain activation in response to numerical order processing. Furthermore, we found a significant association between the neural responses of ordinal processing and arithmetic performance in regions of the semantic control network, especially in the right posterior middle temporal gyrus (pMTG) and at the right inferior frontal gyrus (IFG). Together, these findings indicate that multiple resources work in concert to support the construction of symbolic representations in the brain.
