Abstract: | ABSTRACTResearch on the testing effect demonstrated a stronger decrease in performance for repeated studying compared to repeated testing. The bifurcation model attributes this test-delay interaction to different distributions of item memory strength. The present study tested the assumptions of the bifurcation model for learning foreign language vocabulary. We hypothesised an elimination or reduction of the interaction in a test/feedback condition because feedback prevents the bifurcation of item memory strength. Our experiment based on a 3 (Learning Method within: Test, test/feedback, copy)?×?3 (Retention Interval between: Immediate, 1-week, 2-weeks) mixed factorial design with a sample of N = 122. The greatest long-term retention was achieved in the test/feedback condition. The bifurcation model was supported by a reduced test-delay interaction for the test/feedback condition. Further evidence for the bifurcation model is needed as interpretations on the dropout rates of items with different recall success were limited due to a floor effect. |
