Human Growth and Development / Unit 15 HGD 2133 short lesson, about 20 seconds
Episodic and Autobiographical Memory
Captions available
The idea
Cross-sectional studies show larger episodic-memory declines than longitudinal studies, which find declines subtler and more gradual; hippocampal function declines faster after sixty-five.
In practice
Autobiographical memory's episodic side, details of events, declining while its semantic side, facts about one's life, holds.
Where people slip
The design gap reflects cohort effects: cross-sectional comparisons mix age with generational differences.
