Retention beyond the threshold: Test-enhanced relearning of forgotten information
The effect of repeated testing on delayed relearning of paired associates was investigated. Participants learned two lists of Lithuanian-Dutch word pairs until reaching the criterion of one correct
The contributions of encoding, retention, and recall to the Hebb effect
TLDR
An experiment testing whether the Hebb repetition effect—the gradual improvement of immediate serial recall when the same list is repeated several times—depends on overt recall of the repeated lists shows that encoding is sufficient to generate cumulative long-term learning, which is strengthened by recall.
Free recall enhances subsequent learning
TLDR
A paradigm is introduced that can measure the indirect, potentiating effect of free recall tests on subsequent learning, and a hypothesis for why tests may have this potentiate effect is tested.
Is expanding retrieval a superior method for learning text materials?
TLDR
Overall it was found that repeated testing enhanced retention more than did taking a single test, testing with feedback produced better retention than testing without feedback, but most importantly there were no differences between expanding and equally spaced schedules of retrieval practice.
The pretesting effect: do unsuccessful retrieval attempts enhance learning?
TLDR
The authors examined the effect of unsuccessful retrieval attempts on learning by reading an essay about vision and found that posttest performance was better in the test condition than in the extended study condition in all experiments--a pretesting effect.

TLDR
The results suggested that memory is susceptible to decay and disruption after retrieval, and testing might not insulate memory strength and content from modification, but repeated retrievals might reduce the susceptibility to interference.
Reversing the testing effect by feedback is a matter of performance criterion at practice
TLDR
The results point to the conclusion that the level of retrieval success was the key factor in reversing the testing effect in earlier studies, and application of high retrieval success during practice can produce long-lasting accessible memories even in learning settings applying multiple tests with feedback.
Testing the limits of testing effects using completion tests
TLDR
The results suggest that scope or type of processing required during retrieval practice is likely a critical factor in whether testing will have specific or robust benefits.

Test-Enhanced Learning
TLDR
Investigation of the testing effect with educationally relevant materials and whether testing facilitates learning only because tests offer an opportunity to restudy material concluded that testing is a powerful means of improving learning, not just assessing it.
Different rates of forgetting following study versus test trials
TLDR
It is concluded that study and test Trials have different effects upon memory, with study trials promoting memory acquisition, and test trials enhancing the retrieval process itself, which protects against subsequent forgetting.
The Effect of Overlearning on Long-Term Retention
Once material has been learned to a criterion of one perfect trial, further study within the same session constitutes overlearning. Although overlearning is a popular learning strategy, its effect on
