Number Memory vs. Sequence Memory
Verbal span or spatial span?
Different workloads, different neural circuits—train the one you need most.
Verbal span gain
+2 digits
After 4 weeks of Number Memory focus
Spatial span gain
+1.5 sequences
After 4 weeks of Sequence Memory focus
Modalities & Transfer
Number Memory trains the phonological loop—great for language learning, meetings, and calculations. Sequence Memory trains the visuospatial sketchpad—great for design, gaming, sports, and navigation.
Most people have a dominant modality. Training the weaker modality unlocks balanced cognition.
Difficulty Curves
Number Memory difficulty increases linearly by adding digits. Sequence Memory difficulty increases exponentially as the grid expands. Expect faster wins in Number Memory but more dramatic breakthroughs in Sequence Memory.
Use peg systems with Number Memory to push beyond raw span; use chunking and pattern stories for Sequence Memory.
Programming Tips
Alternate modalities across the week or sandwich them in the same session (Number → Sequence → Applied task). This keeps boredom low and promotes cross-transfer.
During exams or product launches, lean into the modality most relevant to upcoming work.
Action Steps
Test both modalities
Run baseline attempts in Number and Sequence Memory.
Identify dominant vs. weak
Train the weaker modality first to balance cognition.
Combine drills
Plan dual-modality sessions twice per week.

Frequently Asked Questions
Which helps with math?
Number Memory for formulas, Sequence Memory for geometric intuition. Use both for best results.
Do I need to train both forever?
Maintain both monthly. Focus cycles can shift depending on upcoming demands.
