Autobiographical memory refers to the ability to recall personal experiences and events from one's own life. This type of memory includes specific details about past events, such as when and where they occurred, as well as the emotions associated with those experiences. It plays a crucial role in shaping an individual's identity and understanding of their life story. This memory system is distinct from other types of memory, such as semantic memory, which involves general knowledge about the world. Autobiographical memory can be influenced by various factors, including age, cognitive development, and emotional state, affecting how memories are formed and retrieved over time.
