P1-530: DCTCLOCK™ VERSUS MANUAL 10-POINT SCORING METHOD IN PREDICTING AMYLOID BURDEN AND MEMORY PERFORMANCE IN HEALTHY OLDER ADULTS WITH SUBJECTIVE COGNITIVE COMPLAINTS

Cultural stereotypes that equate aging with decreased competence and increased forgetfulness have persisted for decades. Stereotype threat (ST) refers to the psychological discomfort people experience when confronted by a negative, self-relevant stereotype in a situation where their behavior could be construed as confirming that belief. The purpose of this study was to examine the relationships of ST on memory performance in older adults over 24 months. The ST levels on average significantly declined, or improved in the memory training, but not the health training group. Although not significant at the .01 level, the bivariate correlation indicated that change in ST was moderately related to change in verbal memory, suggesting the possibility that improvements (or reductions) in ST may be related to increases in verbal memory scores. We discovered that the unique contribution of ST into the memory performance of healthy older adults offers a possible malleable trait.

Healthy Older Adults

ABSTRACT Objectives: The relationship between wisdom and fluid intelligence (Gf) is poorly understood, particularly in older adults. We empirically tested the magnitude of the correlation between wisdom and Gf to help determine the extent of overlap between these two constructs. Design: Cross-sectional study with preregistered hypotheses and well-powered analytic plan (https://osf.io/h3pjx). Setting: Memory and Aging Center at the University of California San Francisco, located in the USA. Participants: 141 healthy older adults (mean age = 76 years; 56% female). Measurements: Wisdom was quantified using a well-validated self-report-based scale (San Diego Wisdom Scale or SD-WISE). Gf was assessed via composite measures of processing speed (Gf-PS) and executive functioning (Gf-EF). The relationships of SD-WISE scores to Gf-PS and Gf-EF were tested in bivariate correlational analyses and multiple regression models adjusted for demographics (age, sex, and education). Exploratory analyses evaluated the relationships between SD-WISE and age, episodic memory performance, and dorsolateral and ventromedial prefrontal cortical volumes on magnetic resonance imaging. Results: Wisdom showed a small, positive association with Gf-EF (r = 0.181 [95% CI 0.016, 0.336], p = .031), which was reduced to nonsignificance upon controlling for demographics, and no association with Gf-PS (r = 0.019 [95% CI −0.179, 0.216], p = .854). Wisdom demonstrated a small, negative correlation with age (r = −0.197 [95% CI −0.351, −0.033], p = .019), but was not significantly related to episodic memory or prefrontal volumes. Conclusions: Our findings indicate that most of the variance in wisdom (>95%) is unaccounted for by Gf. The independence of wisdom from cognitive functions that reliably show age-associated declines suggests that it may hold unique potential to bolster decision-making, interpersonal functioning, and other everyday activities in older adults.
