These materials were kindly provided by Benjamin Storm. Their use should coincide with attribution to Storm, Bjork, & Bjork (2008). **Note from Dr. Storm:** "I've attached some of the files that I was able to find on my computer, but I am not 100% certain they are the final versions that we ended up using. For example, we removed the instructions for the second and third rounds of retrieval practice because they were redundant. Participants were simply told that another round of retrieval practice was about to commence. I'm sure there are some other small things that got fixed as well (e.g., typos), so be on the look out. Most importantly, however, the materials, timing, and general instructions should be accurate. For a more clear description of the category-exemplar pairs see Appendix C in the attached ms by Anderson, Bjork and Bjork (1994). Our studied items correspond to their strong items, and our to-be-practiced items correspond to their weak items."
