Cognitive monitoring and strategy choice in younger and older adults.
Younger (24- to 39-year-old) and older (60- to 88-year-old) adults learned a list of vocabulary words; one half of the words were studied using a generally more powerful strategy (mnemonic keyword method), and one half mediated with a less powerful approach (generating semantic contexts). Before using these strategies as part of the experiment, neither younger nor older adults judged that the keyword method was more effective and neither group preferred one strategy over the other. After using the strategies and taking a test of strategically studied unfamiliar vocabulary words, the younger subjects reported accurately the relative effectiveness of the two strategies and selected the one that had worked better for them to apply to a subsequent list of vocabulary items. The older participants were not as aware of the differential potency of the strategies and did not rely as much as did the younger subjects on knowledge of strategy utility in making strategy choices. In short, metacognitive awareness of strategy effects produced by monitoring and use of metacognitive awareness in regulating strategy choice were more pronounced in the younger compared with the older sample in this study.
