Episodic Memory (Definition + Examples + Pics)

When you watch a TV show with a narrator, you can put yourself in the other person’s shoes. You see what they are seeing. Hear what they are thinking. And you watch the whole episode play out from their perspective. 

Sometimes, watching a TV show can feel like real life. You may even feel like recalling your memories is like watching an episode of TV, except that you’re the main character. 

That’s because humans have an episodic memory that plays out like a TV show. We are the main character, and we can place ourselves in our memories as if we were the narrator and the audience was watching from our perspective. 

This video is all about episodic memories, how we develop them, and the different types of memories that help us create the story of our lives. If your life was a TV show, what would the story be? In order to find the answer, you’ll have to draw from your episodic memories. 

Definition

Episodic memory is a type of memory that we have personally experienced. When we recall these memories, we can recall where we were, what we were doing, who we were with, how we were feeling, etc. It plays out like an episode of TV or a short scene from a movie. 

Episodic memory falls under the larger umbrella of declarative, or explicit memories. Also under the umbrella of explicit memories is semantic memories. These provide context and information that helps us understand what is happening in each “episode.” 

Example

Here’s an example. Let’s say you have a puppy or a dog. Think about the first time you held the puppy. Or, you might think back to a time where you and your dog played fetch in the yard. Or the event in which your dog got out of the house during a thunderstorm and you had to go find it. 

All of these events are ones that you personally experienced in the past. You can place where you were, what you saw in front of you, the emotions you felt when you played fetch with (or couldn’t find) your dog, etc. As those scenes play out in your head, you are recalling episodic memories. 

Nine Properties of Episodic Memory 

The man behind the term episodic memory is Canadian psychologist Endel Tulving. Tulving has been researching episodic memory for quite some time. He describes it, quite simply, as “mental time travel. He also has this to say about episodic memory:

“Episodic memory is a recently evolved, late-developing, and early-deteriorating past-oriented memory system, more vulnerable than other memory systems to neuronal dysfunction, and probably unique to humans.” 

Since Tulving first started discussing episodic memory in the 1970s, researchers have created nine different “properties” of these memories: 

  • They contain sensory-perceptual-conceptual-affective information

  • The experience is consolidated into your long-term memory, recalled, and consolidated again to make the memory stronger

  • You can recall episodic memories visually 

  • They are recalled from a specific perspective 

  • Each episodic memory is a short “slice” of time and experiences

  • Episodic memories are recalled in relation to a certain time frame 

  • They are vulnerable to being forgotten easily (do you remember every experience of your life? Most likely, no.) 

  • They are specific pieces of your overall autobiographical memory (I’ll discuss this term later) 

  • When you recall them, it’s like you’re reliving them again 

Sense of Self, Sense of Time, Autonoetic Consciousness

Episodic memory is similar to time travel. And like the ability to time travel, the ability to recall and store episodic memories requires certain skills. 

In order to “mentally time travel,” Tulving said that a person needs to have:

  • Sense of self

  • Subjective sense of time

  • Autonoetic awareness

Autonoetic awareness is the ability to see ourselves as we were in the past, the present, the future, and in imaginary scenarios. Think about you as a third-grader. Think about you now. You’re still you in both cases, but you know that you had different thoughts, maybe patterns of behavior, and different experiences. Knowing that you are still the same person you were in third grade, just with different abilities and memories, means that you have autonoetic consciousness. 

Of course, we don’t always have the ability to grasp this concept. Psychologists believe that we gain the abilities required to store and recall episodic memory by the age of 3 or 4. It’s not easy to remember things before that age, because your brain didn’t have the ability to place yourself in your own memories, how you were feeling, and what was going on in each “episode.” 

Flashbulb Memory

Emotion plays a huge role in episodic memory. Let’s go back to the example of seeing your puppy for the first time. Do you remember the moment that your parents told you that you were getting a puppy? What a happy occasion! You might not remember anything else from that day (or even that afternoon, or that hour,) but you remember where you were when your parents said you were getting a puppy. 

Strong emotions can keep memories in our minds for a long time. Researchers have even created a term for short memories backed by high levels of emotion: flashbulb memories. These memories are quick episodes in which we heard news and felt very strong emotions. 

There seem to be a handful of flashbulb memories for each generation. You might be able to recall where you were when you first heard about the 9/11 attacks. Your parents, on the other hand, may also be able to recall where they were when they heard about the Challenger explosion or JFK being assassinated. 

Autobiographical memory

The memory of you getting a puppy or the memory of how the 9/11 attacks affected your life are just two episodic memories. They make up the larger story of who you are and what you have experienced in your life. Like individual TV episodes that tell a larger story, each of your episodic memories are just a piece of who you are.

When you put these episodic memories of your experience together, along with the semantic memories that provide context to each episode, you get a type of memories called autobiographical memories. These are simply memories that tell the story of your life. Flashbulb memories fall under the umbrella of autobiographical memories. 

Understanding these different types of memories, and how they play into your decision-making, can help you make more objective decisions. Our episodic memories are likely to be skewed by our emotions or the process of recalling them over and over again throughout the years. How may those skewed memories change the way you think about yourself and make decisions?
