“Prevalence of direct retrieval in autobiographical memory: Effects of ageing and clinical implications“

by
Lia Kvavilashvili, University of Hertfordshire

Abstract
Growing evidence shows that spontaneous cognitions in the form of mind-wandering, involuntary autobiographical memories, semantic mind-pops, and future thinking are prevalent in daily lives of children and adults across the life span. While research on voluntary forms of episodic and autobiographical memories shows substantial decrements with ageing, studies on spontaneous cognitions have shown small or no age effects, indicating that cue-driven, bottom-up retrieval processes are preserved in typical ageing. Importantly, recent research on voluntary autobiographical memory has shown that such automatic bottom-up retrieval processes are prevalent even in laboratory experiments in which memories often seem to pop into mind in response to a cue word (e.g., cake) without participant using any strategic or generative retrieval to recall a memory.

In this talk, I will present several studies on the effects of age on autobiographical recall, using a laboratory cue-word paradigm, introduced by Uzer et al. (2012), that distinguishes directly (effortlessly) versus generatively (effortfully) retrieval in autobiographical memory. The results of these studies consistently show very high rates of direct retrieval (around 70%) and importantly, no age effects in the number or percentages of directly recalled memories. By contrast, people with Mild Cognitive Impairment, who have increased chances of developing Alzheimer’s disease, did not show the prevalence of direct retrieval that was present in normally ageing older adults. Clinical implications of these findings will be discussed in the light of spontaneous retrieval deficit hypothesis (Kvavilashvili et al., 2020), which stipulates that people at prodromal stages of Alzheimer’s disease have disproportionate reductions in spontaneous cue-driven retrieval processes.
