Memory improves as the brain matures, with myelination speeding signal transmission and growing connections between brain regions that support memory processes like encoding, maintenance, and retrieval. This is why neural development theories are the best fit here—they tie cognitive gains directly to physical brain changes, including connectivity among systems such as the hippocampus and prefrontal areas.

The other ideas focus on different mechanisms: the overlapping waves perspective emphasizes shifting problem-solving strategies over time rather than biological changes in the brain; domain-specific and core-knowledge theories highlight knowledge content and specialized domains rather than general memory improvements driven by brain maturation.
