active recall

Active recall means deliberately retrieving information from memory—rather than simply rereading it—to strengthen learning and retention.

• Cal Newport’s method: For math, he used blank sheets of paper to reproduce proofs from scratch. If he couldn’t do one, he returned to it later; he said this approach transformed his studying. 1
• Andrew Huberman’s method: After reading, step away from the material and try to recall specific details. Then check the source and fill in what you missed. He describes using this approach to learn neuroanatomy and to review papers on a walk. 2 3
• Why it helps: Both describe self-testing as an effective way to learn and retain information. Newport calls it mentally demanding but efficient; Huberman explains that testing helps build knowledge and offset forgetting. 4 5
