Data from Touron, Swaim, and Hertzog, 2007, with increases in memory retrieval use plotted over training with repetition of noun-pairs for younger adults (black) and older adults (red). We separate retrieval use by between-subjects conditions that provided either standard task instructions, instructions that the memory strategy is preferred, or instructions that the memory strategy is preferred coupled with modest monetary incentives to use memory.
