Test both modalities
Run baseline attempts in Number and Sequence Memory.
Clear comparison
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 digitsAfter 4 weeks of Number Memory focusSpatial span gain
+1.5 sequencesAfter 4 weeks of Sequence Memory focusModalities & 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
Identify dominant vs. weak
Train the weaker modality first to balance cognition.
Combine drills
Plan dual-modality sessions twice per week.
