The aim of the present study was to assess the influence of word image vividness on the immediate and long-term recall (one-day interval) of words using either the rote repetition learning method or the keyword mnemonics method in a sample of adults aged 55 to 70 years. Subjects learned a list of concrete and abstract words using either rote repetition or keyword mnemonics. Individuals using keyword mnemonics recalled more concrete than abstract words both immediately after learning and after a one-day time interval. In contrast, subjects using the repetition method recalled more abstract than concrete words immediately after learning; however, no difference in the number of recalled concrete and abstract words were found after the one-day interval. These findings are discussed in the context of previous studies, and new lines of research are proposed. (Contains 2 tables.)
