• The testing effect describes the finding that retrieval practice compared to study practice enhances memory performance. Prior evidence consistently demonstrates that this effect can be further boosted by providing feedback after retrieval attempts (test-potentiated encoding, TPE). The present PhD thesis was aimed at investigating the neural processes during memory retrieval underlying the beneficial effect of additional performance feedback beyond the benefits of only adding correct answer feedback. Three studies were conducted and behavioral as well as neural correlates (collected with electroencephalography and functional magnetic resonance imaging) of feedback learning were examined.
