Elaboration is useful for memorizing meaningful material, including new vocabulary words, sentences, people’s names, directions, or even phone numbers. Ironically, elaboration does not need to be very elaborate to make a difference. In one study, participants had to memorize one hundred words (Tresselt & Mayzner, 1960). There were three conditions: cross out the vowels, copy the words, and judge the degree to which each word was an instance of the concept “economic” (e.g., poem would be low, and credit would be high). When asked to remember the words, participants in the judge condition did twice as well as the copy condition and four times as well as the cross-out-vowels condition.
