Final answer:
Episodic memory refers to a type of long-term, declarative memory about events personally experienced. It involves the recollection of specific events, places, and times, distinguished by personal narratives and sensory details. It contrasts with semantic memory, which deals with general knowledge and concepts, and is different from implicit memory, which is not consciously recalled.
Step-by-step explanation:
Definition of Episodic Memory
Episodic memory is a type of declarative memory that contains information about events we have personally experienced, also known as autobiographical memory. It is the memory of specific episodes or events, including the context in which they occurred, such as the time and place. It encompasses the 'what', 'where', and 'when' of an event. For example, the memory of celebrating your last birthday would be an instance of episodic memory. It is usually recounted as a narrative and involves personal recollections and sensory perceptions like visual imagery and emotions tied to the event.
Contrasting Semantic and Episodic Memory
In contrast, semantic memory is concerned with knowledge about words, concepts, and facts that are not tied to personal experiences. This includes language-based knowledge, such as the meaning of words or general knowledge facts, like the first African American president of the United States.
Understanding Implicit Memory
Implicit memory, on the other hand, includes memories we are not consciously aware of, such as procedural memory that involves skills and tasks learned through repetition. It does not involve conscious recollection but is demonstrated through performance of tasks, revealing the influence of previous experiences.
