Adult age-related changes in the specificity of episodic memory representations: A review and theoretical framework

We provide a comprehensive review describing research on the qualitative representational nature of older adults' episodic memories. Our review considers several broad theoretical frameworks and decades of research converging on a universal principle of adult aging: Episodic memory in older adulthood is characterized as being less specific in nature than in younger adulthood. Going beyond earlier specific reviews on related topics in the false memory, neuroscience, and reading comprehension literatures, our review synthesizes findings from these fields with more recent research from the precision literature, along with several new studies on age differences in the specificity of associative aspects of episodic memory, where age deficits have long been reported. We also sketch a new theoretical framework as inspiration for future research that can better elucidate the mechanisms underpinning age differences in the specificity of memory representations, including reduced attentional resources and slower speed of processing.
