Consolidate peg images with spaced review

Test your peg links at expanding intervals before they fade, not after.

Why it works

Mnemonic images are vivid at encoding but fade over hours and days without retrieval practice. Spaced retrieval strengthens the memory trace each time it is reconstructed — a process called reconsolidation — and forces active retrieval rather than passive re-reading, which is among the most durable encoding strategies studied.

How to do it

1. After encoding a set of peg images, close the material and retrieve from memory within 10 minutes.
2. Retrieve again after 24 hours, then 3 days, then 1 week.
3. Any item you retrieve incorrectly resets its interval to the shortest.
4. Integrate with a spaced-repetition tool if maintaining a large set.

Evidence

Spaced retrieval practice (the "testing effect") is one of the most robustly supported principles in memory research, with benefits across age groups and material types. (rct)

This evidence applies to retrieval practice generally; the specific interaction with mnemonic imagery is less studied, though no mechanism predicts they would conflict.

Common mistake

Reviewing by re-reading your image notes rather than closing them and attempting pure recall — passive review feels successful but does not strengthen the retrieval path.
