Imagination Requires Memory January 9, 2008Posted by Mrs Weird Scientist in Human Body, Psychology and Behavior, Tough Stuff.

As kids and teens, we imagine all sorts of stuff – what we want to be when we grow up or maybe even becoming famous. We hear about kids having vivid imaginations and big dreams for the future. Older adults, on the other hand, can struggle to remember past events and imagine new ones. We obviously know that adults have imaginations too but what makes it different and not always so intense?
A new study performed at Harvard University has shown that the ability of adults to create imaginary scenarios is linked to their ability to recall detailed memories. The full study results can be viewed in the Psychological Science journal.
If you didn’t already know, we have different types of memory. One type is called episodic memory. This kind of memory refers to personal memories of past experiences. It’s what lets you go backwards and forwards in the recollection of an event in time. Basically, episodic memories are connected to a specific time and place. If I asked what you had for dinner last night, you would be using episodic memory to answer. Think of episodic memory as being endless snapshots of different moments in your life.
Getting Back To Imagination
So, how does episodic memory relate to imagination? Simple. In order to create and imagine future events, a person needs to remember a previous event. Then, they need to take out bits and pieces from the specific details of the event before they can piece it all back together to form a new, imagined event. There’s even a name for this process – it’s called constructive episodic simulation.
Testing It Out
Psychologists from the university asked young and older participants to respond to various randomly chosen cue words with past and future scenarios. Researchers Donna Rose Addis, Alana Wong and Daniel Schacter then looked at the results, which showed that older adults had a significant reduction in their use of episodic memory to describe past memories and imagined future events. It’s interesting to think about memory being so important in the process of imagination. It just goes to show that all the stuff you do plays a special part in allowing you to imagine new and exciting things, which then creates even more episodic memories.
As for me, I don’t qualify as an older person just yet, I hope. So, I will use my episodic memory to the best of its ability as I imagine what it would be like to finish all of my work this week and take a very long vacation around Europe!
