Abstract
Because the risk for cognitive pathologies such as Alzheimer’s Disease increases with advancing age, there is a critical interest in understanding the pathways that promote healthy cognitive aging. In this talk, we examine self-reported Big 5 personality traits among adults who showed risk for amnestic (memory specific deficit) and non-amnestic (deficit in one or more cognitive domains) subtypes of mild cognitive impairment (MCI), based on psychometric classification. Psychometric classification of amnestic and non-amnestic MCI risk was defined using methods described in Payne & Stine-Morrow (2016). Those adults with non-amnestic MCI scored higher on agreeableness relative to non-impaired and amnestic MCI subtypes. Those adults at risk for non-amnestic MCI reported lower openness than non-impaired and amnestic MCI subtypes. There was a marginal trend for amnestic MCI to score lower on conscientiousness than non-amnestic subtypes. Collectively, these findings highlight the potential that personality traits play in shaping trajectories of non-normative cognitive aging.
