More than Education: Openness to Experience Contributes to Cognitive Reserve in Older Adulthood

Cognitive reserve (CR) is a well-known indicator of resilience to cognitive decline in older adulthood. Although higher education is the most widely-recognized contributor to CR, research suggests that the personality trait Openness to Experience might also contribute to reserve in later life. The purpose of this study was to examine whether the personality trait Openness contributes uniquely and independently to CR (above and beyond education). 72 adults (M=70.46 years old, SD=6.82) completed the WAIS-III Information subtest (measuring CR), the NEO Personality Inventory-Revised (measuring Openness), and the Dementia Rating Scale-2 (measuring global cognitive status and used in validity analyses confirming Information as a CR proxy). Openness accounted for unique variance in Information above and beyond demographics and education, with some evidence of a greater effect at fewer years of education. These results provide preliminary evidence supporting the association between Openness to Experience and CR, a known indicator of resilience to cognitive decline in older adulthood.
