Autobiographical event memory and aging: older adults get the gist

Cognitive aging is often viewed through the lens of loss of function. Research examining the way older adults remember autobiographical event memories, therefore, has focused on how aging reduces the ability to form and retrieve specific details, with less emphasis on understanding the aspects of event memories that are preserved among older adults. We propose that at the heart of what is preserved in older adults' autobiographical event memories is the selective sparing of the ability to store and retrieve the gist. We discuss why older adults' reliance on gist may be driven by multiple factors beyond cognitive decline, including changes in goals that come with age. We propose that older adults' ability to retrieve episodic autobiographical events, although often viewed through a lens of decline, reveals much about what is preserved and prioritized in cognitive aging. Central to our proposal is the idea that the so-called gist of an autobiographical event is not only spared with normal aging but also well adapted to serve memory-guided behavior in older age. To support our proposal, we review cognitive and brain evidence indicating an age-related shift toward gist memory. We then discuss why this shift likely arises from more than age-related decline and instead partly reflects a natural, arguably adaptive, outcome of experience, motivation, and mode-of-thinking factors. Our proposal reveals an upside of age-related memory changes and identifies important research questions.

At a conceptual level, autobiographical event memory is definitionally synonymous with episodic memory, although there are important methodological differences (see episodic memory). Relatedly, autobiographical event memories are believed to typically include general or nonspecific detail that is often described as semantic memory (see semantic memory). conceptually akin to autobiographical event memory in that both are believed to reflect consciously retrieved unique events bound to a time and place. However, methodologically episodic memory is often tested with nonpersonal stimuli. The number of event-defining elements also is often much more limited relative to autobiographical event memories, and generalities are often controlled (e.g., all pictures of outdoor scenes). a general memory for the superordinate, basic category, and prototype features of elements making up a singular event. Applied to autobiographical events, gist representations capture the basics about who, what, and where, as well as an event's general storyline and emotion. Gist representations serve as a solid conceptual base from which to draw meaning and to make connections with related experiences. knowledge of autobiographical and nonpersonal concepts or 'facts.' Semantic memories are derived from experience but are believed to be retrievable without reconstructing the specifics around the time and place from which they were extracted. memory for concrete features of elements that constitute a singular event. Applied to autobiographical events, specific representations capture visual, auditory, and other sensory modalities and are defined as any detailed information that adds to an event's uniqueness, including an element's physical features and location, the length of time and sequencing of actions within an event, and a verbatim-like record of dialogue.
