Encoding Systems

Create a digit-to-image table (0=hero, 1=candle, 2=swan). Combine images for each chunk and place them in a story. The more sensory detail, the better.

Scheduling Practice

Use 3-1-3 structure: three attempts, short break, three attempts. Stop when accuracy drops below 70%.

Plateau Busting

Change variables—play standing up, switch devices, or add background noise to build robustness.

Action Steps

Create encoding

Assign images or syllables to digits 0-9.

Map palaces

Use familiar locations to store sequences.

Review weekly

Revisit best strategies and adjust.

Frequently Asked Questions

Should I say numbers out loud?

Use subvocal rehearsal to avoid distracting others while still reinforcing memory.

What if I forget mid-sequence?

Abort, breathe, and visualize the chunk again. Rushing increases errors.
