Episode 5 - Bite-Size Research on Spaced Retrieval

Oct 18, 2017
This episode discusses the benefits of spaced retrieval practice for higher order learning. An experiment showed that spaced retrieval practice improves performance on both factual and application questions. It also reveals that taking a review quiz after eight days is more effective than after one day. Spaced retrieval practice enhances memory and boosts performance on unpracticed questions.

Quick takeaways

  • Spaced retrieval practice is effective in both lab studies and realistic classroom settings, improving memory of factual information as well as performance on complex application questions.
  • Spacing out retrieval practice can lead to a carryover effect, enhancing the retention and application of related information even if it was not explicitly practiced.

Deep dives

Space retrieval practice enhances memory and application

In this podcast episode, the hosts discuss a study that examines the benefits of space retrieval practice, which combines spaced practice and retrieval practice, on higher-order learning. The study involved undergraduate psychology students who were taught a lecture on meteorology and then given a review quiz either one day or eight days later. The quiz included both factual and application questions. The results showed that students who took the review quiz after eight days performed better on both types of questions compared to those who took it after one day. The study highlights the importance of spacing out retrieval practice and its positive impact on memory of factual information as well as performance on complex application questions.
