An episodic memory is a memory of a specific event. Because each person has a different perspective and experience of an event,
episodic memories of that event are unique to each person. Show
Closely related to this is what researchers refer to as autobiographical memory—memories of your own life history. As you can imagine, episodic and autobiographical memories play an important role in your self-identity. What Is Episodic Memory?Episodic memory is a category of long-term memory that involves the recollection of specific events, situations, and experiences. Imagine that you get a phone call from an old college friend. You spend an evening reminiscing about amusing moments from your days at school. Your memories of those specific events and experiences are examples of episodic memory. These memories provide you with a sense of personal history as well as a shared history with other people in your life. Episodic memories are important because they allow you to recall personal experiences that helped shape your life and perceptions. Several parts of the brain work in concert to help you store and retrieve episodic memories: the temporal, parietal, and frontal cortices, diencephalon, and cerebellum. Practice, genetics, and experience all influence your ability to recall episodic memories. Episodic vs. Semantic MemoryThe term episodic memory was first introduced by Endel Tulving in 1972 to distinguish between remembering events from the past (episodic memory) and knowing factual information, which is known as semantic memory. Semantic memory is focused on general knowledge about the world and includes facts, concepts, and ideas. Episodic memory together with semantic memory is part of the division of memory known as explicit or declarative memory. Types of Episodic MemoriesEpisodic memories fall into a few main categories. Specific EventsThese involve memories of particular moments from personal history. Your first kiss, first day of school, a friend's birthday party, and your brother's graduation are all examples of episodic memories. In addition to your overall recall of the event itself, the episodic memory include the locations and times of the events. Personal FactsKnowing who was president the year that you got married, the make and model of your first car, and the name of your first boss are all examples of personal fact episodic memories. General EventsRemembering what a kiss feels like is an example of this general type of memory. You do not remember each and every kiss you've ever shared, but you can recall what it feels like based on your personal experiences. Flashbulb MemoriesFlashbulb memories are vivid and detailed "snapshots" related to finding out particularly important news. Sometimes these moments might be highly personal, like the moment you found out that your grandmother had died. In other cases, these memories might be shared by many people in a social group. The moments you found out about the 9/11 attacks or the Paris concert theater attacks are examples of shared flashbulb memories. Examples of Episodic MemoriesSome examples of episodic memories might include:
Remember, each person's episodic memory of an event is entirely unique. Even other people who shared the same experience may have different recollections of what happened. 9 Properties of Episodic MemoryResearch indicates that episodic memory carries nine attributes. Other types of memory feature some of these, too—but only episodic memories comprise all of them. Episodic memories:
Impact of Episodic MemoryResearchers have found that episodic memory can also be interdependent with semantic memory. On learning tasks, participants performed better when new information was aligned with prior knowledge, suggesting that semantic knowledge of a task provides a sort of framework for new episodic learning. Participants were asked to remember the prices of grocery items. Those in the control group were better able to remember these prices when the new information was congruent with their existing episodic memories of grocery prices. Amnesiac participants in the experimental group, however, performed much worse at remembering new information because they did not have access to episodic information from their past. Conversely, researchers have also found that episodic memories also play a role in the retrieval of semantic memories. In experiments where participants were asked to generate lists of items in particular categories, those who were able to rely on episodic memories performed better than amnesiac participants who did not have access to episodic memories. Studies also suggest that there are sex differences in episodic memory. Research has found, for example, that women tend to outperform men on tests of episodic memory function, particularly on verbal-based episodic memory. Studies also show that women are able to access these memories faster and date them more accurately than men. How Damage and Disease Can Affect Episodic MemoryAging and neurodegenerative diseases take an extreme toll on episodic memory. For example, a decline in the ability to retrieve this kind of memory is among the first signs of Alzheimer’s disease. Other psychiatric conditions such as dissociative disorders, schizophrenia, and Parkinson's disease also feature
deficits in episodic memory functions. However, such damage is difficult to assess because memories are difficult to induce and measure. Likewise, traumatic brain injury, such as concussion, tends to impede episodic memory. Semantic memory appears to be less susceptible to this kind of damage.

Thanks for your feedback! What is the memory of general knowledge?Semantic memory refers to general world knowledge that humans have accumulated throughout their lives. This general knowledge (facts, ideas, meanings, and concepts) is intertwined in experience and dependent on culture.
What are memories for general facts and personal information called?declarative memory: Memory of facts and personal information that requires a conscious effort to bring to mind (also called explicit memory).
What type of memory is used to state and use facts and concepts?Explicit memory refers to knowledge or experiences that can be consciously remembered. As you can see in Figure 9.2, “Types of Memory,” there are two types of explicit memory: episodic and semantic.
What memories involve both facts and general knowledge?Semantic memory involves the recall of ideas, concepts, and facts commonly regarded as general knowledge. Episodic memory, on the other hand, involves the recollection of personal events or episodes in a person's life, such as birthdays.
