Slamecka & Graf (1978), JEP:HLM 4(6) — Generation Effect: generated words beat read words across cued/uncued recognition, free and cued recall, and confidence
Summary
Claim: Slamecka & Graf (1978), "The Generation Effect: Delineation of a Phenomenon," Journal of Experimental Psychology: Human Learning and Memory 4(6), 592-604. Five experiments; generated words beat read words across cued/uncued recognition, free and cued recall, and confidence ratings.
Source: Slamecka & Graf (1978), JEP:HLM.
Confidence: Verified (foundational).
Nuance: Slamecka & Graf's own Experiment 3 found no significant generation effect on the stimulus terms — i.e., the benefit is not simply "heightened attention to everything."
Why this matters for Candid: Foundation for "make the user produce inputs" as a real memory and engagement lever. Anchors R4 — Where appropriate, make the user GENERATE inputs (not just pick from menus) — the generation effect d≈0.40 is real but ceilings beyond ~900 words and doesn't scale to expository text.
