Expanding retrieval, increasing the delay between retrieval attempts of recently studied material, should lead to better memory than equally spaced retrieval, however, recent results have been mixed. Ninety-six participants studied word pairs with the following expansion schedules: 1-2-3; 1-5-9; 3-5-8; 5-8-13. An evenly spaced (5-5-5) condition was also used. A final test was given after a 10 minute or 48 hour retention interval. Performance after the 48 hour retention interval was best in the 5-8-13 condition. The higher level of performance in this condition was due to no forgetting between the final learning trial and the immediate final test.
