Retroactive inhibition (RI) has long been recognized as one of the most potent factors in forgetting. Of relative recent treatment is the forgetting produced by the operations defining proactive inhibition (PI). If RI is defined as a decrement in the recall of an activity as a result of other activity intervening between the original learning and recall, PI may be defined as a decrement in recall as a consequence of an activity which took place prior to the original learning.
