Instructing Use of an Effective Strategy Improves Recognition Memory in Healthy Adults

Area of Science:

• Cognitive Psychology
• Neuroscience of Aging

Background:

• Age-related memory decline is linked to reduced use of effective memory strategies.
• It remains unclear if teaching these strategies can overcome memory differences.

Purpose of the Study:

• To investigate if teaching mnemonic strategies can mitigate age-related associative memory deficits.
• To examine the impact of strategy instruction on memory performance over time in healthy adults.

Main Methods:

• Longitudinal study of 276 healthy adults (18-79 years) over 5 testing occasions (2-year intervals).
• Assessed associative and working memory, and beliefs about mnemonic strategies.
• Introduced sentence generation strategy instruction from the third testing occasion.
• Utilized continuous-time dynamic modeling to analyze changes and intervention effects.

Main Results:

• Younger age, better working memory, and stronger belief in mnemonic strategies predicted better memory recognition.
• Instructional intervention significantly reduced associative memory deficits, with some lasting effects.
• Age, sex, meta-memory beliefs, working memory, and metabolic health were considered in the analysis.

Conclusions:

• Imparting effective mnemonic strategies shows potential for mitigating age-related associative memory deficits.
• Strategy instruction can be a viable approach to support memory function in aging adults.
