You knew it a moment ago
- A name you cannot produce arrives instantly when someone offers three options.
- The memory was there the whole time; getting it out was the problem.
- Retrieval 提取 is a separate process from storage, and it has its own rules.
Recall and recognition
- Recall 回忆 is remembering without cues — an essay question.
- Recognition 再认 relies on cues — a multiple-choice question.
- Recognition is easier, which is why a test format can change a score without any change in learning.
A multiple-choice question tests mainly...
The options act as cues, which makes it a recognition task.
Retrieval depends on the situation
- Context-dependent memory 情境依存记忆 improves recall in the same environment as learning.
- State-dependent memory 状态依存记忆 improves it in the same internal state.
- Mood-congruent memory 心境一致性记忆 makes memories matching your current mood easier to reach.
Recall, recognition, or a matching effect?
Sort each situation by the retrieval idea it illustrates.
Context-dependent memory means recall improves when the environment matches the one where learning happened.
Storage was equal; the retrieval context is what differed.
Select all the matching effects the CED names.
Serial position is an encoding effect, not a retrieval-matching one.
Feeling that you "know" material after re-reading is a recognition judgement, and the exam will ask for recall. This is a real, measurable trap, not study advice — the CED names metacognition precisely because these two feelings are easy to confuse.
The finding that being tested improves later memory more than re-reading is the ____ effect.
The testing effect is why retrieval practice beats review.
Retrieval practice
- Successful retrieval is more likely after retrieval practice 提取练习.
- The testing effect 测试效应 shows that being tested improves later memory more than re-reading does.
- Metacognition 元认知 — judging what you actually know — makes study time go where it is needed.
Match each study method to what it actually exercises.
The comfortable method exercises recognition; the effective one exercises recall.
What this means for studying
- Re-reading feels effective because the material looks familiar — that feeling is recognition, not recall.
- Self-testing feels harder because it demands recall, which is why it works better.
- The comfortable method and the effective method are not the same method.
Students who learned a word list underwater recalled more of it underwater than on land. The words were equally well stored in both groups — the context at retrieval is what differed.
Recall works without cues, recognition with them. Context-, state- and mood-congruent memory all improve retrieval when the situation matches learning. Retrieval practice and the testing effect beat re-reading, and metacognition tells you which you need.
