The increased ability of the brain to recall information due to using the Divide and Conquer flash card strategy and the Cornell Note Taking system is primarily attributed to multisensory input.
Both methods engage different modes of learning (visual, auditory, and kinesthetic), which can enhance memory retention and recall by creating stronger neural connections. The use of different strategies helps to reinforce the material through multiple senses, making it easier to remember.
While other options like "meaning before detail" and "synaptic memory" may also play roles in learning and memory, multisensory input is most directly connected to the effectiveness of these specific note-taking and study strategies.
