Source monitoring

When you feel you know something, also ask yourself where you learned it and how recently.

Why it works

FOK can be driven by familiarity with the cue rather than actual encoding of the answer — the word looks familiar because it appeared in a paragraph you read, not because the fact it refers to was encoded. Source monitoring — tracking when, where, and how you encountered information — reduces this familiarity-based inflation by requiring the learner to distinguish genuine encoding from mere exposure.

How to do it

1. When you have a feeling of knowing, add a second question: "Where did I learn this?"
2. If you cannot name a source or context, treat the FOK with additional skepticism.
3. After recall tests, note whether correct recalls had clear source memories; incorrect ones often lack them.
4. When reviewing new material, deliberately encode context: "I learned this in chapter 3, from the diagram."

Evidence

Source monitoring research (Johnson, Hashtroudi & Lindsay, 1993) shows that memory for source is distinct from memory for content, and that familiarity-based FOK without source information is a reliable predictor of recall failure. (observational)

Source monitoring failure increases with age and is influenced by encoding conditions; the source-memory prompt is a useful heuristic rather than a precise diagnostic.

Common mistake

Treating familiarity with the question stem as evidence that you know the answer — a confusion between recognizing the cue and knowing the content it refers to.
