Elementary school students in the U.S. are often taught to use the very familiar word "HOMES" as a cue for remembering the names of the Great Lakes (each letter in "HOMES" provides a first-letter cue for one of the lakes: Huron, Ontario, Michigan, Erie, Superior). This memory procedure usually works better than repeating the names over and over. The use of this familiar word provides an example of a. implicit memory. b. a self-reference effect. c. elaborative rehearsal. d. repetition priming.
