01//DefinitionTerm

// ##test-def =Testing Effect — the finding that long‑term memory is enhanced when some of the learning period is devoted to retrieving information (testing) rather than merely restudying it. .Also known as retrieval practice or test‑enhanced learning. .Robust across materials, ages, and test formats. →The act of recall strengthens memory more than passive review.

02//MechanismWhy it works

// ##test-mech ~Elaborative retrieval — during recall, you activate related information, strengthening the network. ~Search practice — the act of searching memory makes the path to the target more accessible later. ~Reconsolidation — retrieved memories are re‑encoded, potentially updating and strengthening them. .Testing with feedback corrects errors and reinforces correct traces.

03//CLN ConnectionApplication

// ##test-cln →Reading a CLN document is passive encoding (shallow). →But the trace panel turns past interactions into retrieval cues. →Clicking a trace forces you to recall: "What was this about? Why did I tag it?" →Each click is a mini‑test — you retrieve the context before jumping to the line.

04//Trace Retrieval as TestingMechanism

// ##test-retrieval +Trace list shows only a preview (tag/decision snippet) — you must recall the full context. +After attempting recall, clicking jumps to the line, providing immediate feedback. +This is a form of cued recall with feedback — a powerful learning paradigm. +Repeatedly revisiting traces across sessions implements spaced retrieval practice.

05//Open QuestionsFuture

// ##test-open ?Can trace previews be designed to optimise retrieval effort (e.g., progressive hints)? ?What is the ideal spacing of trace reviews for long‑term retention? ?Should the system prompt users to review old traces automatically (spaced repetition)? ?Does the testing effect combine with generative effect when you re‑generate a tag?
