Study Notes
Testing and Error Generation in Memory
- Testing and generating answers, especially incorrect ones, can strengthen memory, particularly when feedback is provided.
Kornell et al. (2009) Experiments
- Six experiments tested participants on trivia questions and weakly associated word pairs.
- Experimental conditions compared testing with an answer generation phase to a control condition where the answer was presented directly (read only).
- A critical aspect was equating conditions for exposure to answers to isolate the direct effect of generating and testing.
- Recall was significantly better in the test condition for the trivia questions, even when feedback was shown for significantly shorter time than read-only trial, demonstrating the benefit of generating errors.
- Experiment 2, however, showed no benefit of generating errors, potentially due to limited exposure time.
- Successful generation of incorrect answers and subsequent feedback proved crucial.
Benefits and Boundary Conditions
- Generating errors benefits memory by pushing for semantic understanding, creating additional cues for later recall.
- This effect is more pronounced for questions with strong semantic associations between question and answer, weakening with unrelated pairs.
- The benefit is present with multiple-choice formats, but less consistent in cued recall situations.
Kornell (2014) - Trivia Question Experiments
- Four experiments confirmed the previous observations for word pairs and extended them to meaningful trivia questions.
- Testing improved learning even with delays in feedback (up to 24 hours).
- The benefit depended on the intrinsic meaningfulness of the questions. Richly associated trivia questions showed substantial improvement even with delays, whereas those with less meaningfulness benefited primarily from immediate feedback.
The Generation Effect (Slamecka & Graf, 1978)
- Generating an answer from memory results in better memory than simply reading an answer.
- This differs from Kornell's finding, where the focus is on the process of generating and potentially incorrect answers.
Potential Explanations and Further Research
- Potential confounding effect of item interleaving (mixing generate and read items) might contribute to the "generation effect" in some studies.
- Future research should explore the issue using blocked designs.
