Goodmon and Anderson (2011) showed not only that prior retrieval enhances later retrieval of those same words (Rp+ items), but that remembering words related to practiced words (Rp - items) can suffer as a result of prior retrieval compared to unrelated words (NRp items). By comparing the recall for Rp - and NRp items, the experiment showed a 13% RIF effect . </Td> </Tr> <P> Retrieval - induced forgetting (or RIF) is a memory phenomenon where remembering causes forgetting of other information in memory . The phenomenon was first demonstrated in 1994, although the concept of RIF has been previously discussed in the context of retrieval inhibition . </P> <P> RIF is demonstrated through a three - phase experiment consisting of study, practice of some studied material, and a final test of all studied material . Such experiments have also used multiple kinds of final tests including recall using only category cues, recall using category and word stems, and recognition tests . The effect has been produced using many different kinds of materials, can be produced in group settings, and is reduced in special clinical populations . </P>
