Retrieve before rereading
Before reopening the source, write, explain, solve, sketch, translate, or perform what you can from memory. Then compare. The comparison exposes gaps that passive familiarity may hide.
Check and correct immediately enough to learn
After the retrieval attempt, use the source, answer key, teacher, coach, test, or other appropriate feedback to identify what was correct, missing, or confused. Write the corrected version instead of only marking 'wrong.'
Return after time has passed
For material worth keeping, schedule another retrieval attempt later rather than doing all review immediately. The exact interval depends on importance, difficulty, deadline, subject and prior performance. DEPTH-01 deliberately avoids a universal spacing formula.
Memory results do not define the person
Difficulty recalling something may come from weak encoding, insufficient practice, interference, stress, fatigue, task design, unfamiliarity, language, health, or many other factors. A log can guide practice; it is not a neurological or psychological assessment.
Historical 14-day and fixed schedule examples remain examples
The Level 01 source contains a 14-day memory program and suggested return intervals. Those are preserved as historical exercises, not promoted here as universally optimal. The public tool records planned return points and asks the learner to adjust from actual results.
Reflection
Questions to sit with
- What can I retrieve before looking?
- What was missing or incorrect after checking?
- When is a useful next return for this material?
