Research Focus

Dr. Yoneda's research investigates the links between personality and cognitive aging, as well as the mechanisms underlying these relationships, particularly the interplay between personality and physiological factors. She is passionate about elucidating factors that contribute to cognitive healthspan and optimal development in older adulthood; specifically, under which circumstances, for whom, and how do psychological factors influence physiological and cognitive processes, and vice versa.

Recurring themes throughout her research are advanced methodologies effective for modelling repeated assessments at various timescales, large conceptual replications across countries and cultures, and use of multi-method data, including self-report, objective data (e.g., accelerometer), neuropathology indicators, and physiological biomarkers (e.g., blood pressure).
