Retrieval Induced Forgetting (RIF) shows that selective retrieval of memories can impair later retention of related contents that compete for access during memory retrieval (Anderson, Bjork, & Bjork, 1994). According to previous experiment with the retrieval practice paradigm, inhibition of related contents disappeared when a delay of 24 hours is introduced between Retrieval practice (RP) and the final memory test (MacLeod & Macrae, 1999). In three experiments we further explored this finding using specific-cue-independent final test and introducing the idea of spacing retrieval in RP paradigm. Spacing promote long lasting effects of practice (Bjork, 1975), hence we wanted to explore if spaced retrieval practice modulated temporal effects of retrieval inhibition. In Experiment 1 and 2, we assessed temporal effects of RIF and replicated MacLeod & Macrae results but with specific-cue-independent final tests. In Experiment 3, we applied a spacing practice schedule to the RP paradigm. Result supported our hypothesis.
