Summary

This series of experiments has clearly demonstrated that the brain systems necessary for performing mental arithmetic are both widespread and dynamic. Previous models of numerical cognition, namely the triple-code model and its recommended extensions, link arithmetic skill to the semantic memory system. However, results of this investigation suggest that some aspects of arithmetic skill also draw on aspects of the episodic and procedural memory systems. Though further research is warranted, a critical point made in this dissertation is that mental arithmetic is very much a distributed process, and its neural correlates are heavily influenced by factors such as strategy and practice.
