Stimuli. Our 6 animal categories, each containing 8 pictorial exemplars, were assigned to either the Rp (retrieval practice) or Nrp (baseline) condition in a counterbalanced fashion across participants. Proper names beginning with the first letter of the relevant category were randomly assigned to the individual pictures, which were also randomly divided into an A-set and a B-set. Image–name pairs randomly assigned to the A-set of Rp categories populated the Rp− condition, and the other half of the items populated the Rp+ condition. Items in the Nrp categories were also randomly split between the Nrpa and Nrpb conditions.
