Overview

Prior research has consistently demonstrated that word recall decreases over successive trials of similar words (proactive interference). A way to improve subsequent memory is by using words that are semantically different from previous trials or have different meanings. This is thought to overcome the proactive interference seen in semantically similar trials. To further assess this phenomenon, participants completed trials of stimulus words to recall, subsequent trials of words that had different meanings, and then an additional trial of words that had words with meanings the same as the first trial. The accuracy of these trials was assessed to see if proactive interference was reduced or increased throughout these trials of varied semantics. It was shown that recall accuracy actually decreased for all trials demonstrating that proactive interference was maintained.
