1) Autobiographical memory (AM) refers to memories of personal experiences and facts about one's life. It includes both autobiographical episodes of specific events and autobiographical knowledge of general facts.
2) AM follows predictable patterns across the lifespan, including childhood amnesia for early memories, a "reminiscence bump" with more memories from adolescence/young adulthood, and gradual forgetting over time.
3) Emotional events tend to be remembered more vividly due to enhanced consolidation and the involvement of the amygdala in processing emotional memories.
