Delayed testing over immediate review

Test yourself after a delay rather than immediately after study to get an accurate FOK reading.

Why it works

Immediately after studying, material is highly accessible in working memory, producing an artificially high FOK and inflated test performance. The FOK signal is partly tracking short-term accessibility, not long-term retention. Testing after a delay (24 hours or more) lets short-term accessibility fade, so FOK and test performance reflect actual durable encoding rather than temporary activation.

How to do it

1. After a study session, resist testing yourself immediately.
2. Schedule the test for at least 24 hours later (next-morning review is a good minimum).
3. Before the test, make your FOK judgment about how well you expect to remember.
4. Compare the FOK to outcomes — the gap is more honest than after immediate review.

Evidence

The spacing effect is among the best-replicated findings in memory research: delayed testing produces better long-term retention than immediate review. Immediate testing also inflates FOK accuracy relative to retention. (rct)

Delayed testing reduces immediate performance — it can feel like forgetting rather than learning — making it psychologically aversive to adopt even when it is more effective.

Common mistake

Studying and testing in the same session, then using the high test score as evidence that material is learned — which conflates temporary accessibility with durable retention.
