Memories are not stored in one location but rather get stored all over the brain. Long-term memoryĭisney’s Inside Out does a beautiful job of depicting what long-term memory is like in the brain. But, if the robots use this information in a meaningful way, they will likely transport it over to a shelf for long-term storage.
But, if the robots are not constantly getting commands from the main computer (your conscious mind) to tell them what to do they may drop the information in the incinerator too. Back to the conveyor belt analogy, working memory is like robots picking information off the conveyor belt to use for some goal (like getting to the ice cream shop). You may mindfully rehearse them a few times to get them to “stick”. For example, keeping directions in your head. Working memory is the opposite, it is an active process we have to think about. Like I said above, short-term memory is a passive process we don’t ‘think’ about it, it’s just there for us to access. Working memory and short-term memory may seem similar but they are actually quite different. However, to truly remember information it has to be taken off the short-term memory conveyor belt. Short-term memory is something we really do not ‘think’ about we just have access to it. This allows you to at least make up a plausible answer to the question. Even though you were not attentively listening, you may be able to vaguely remember the question because the auditory information is still on the short-term memory conveyor belt. For example, you may be day dreaming in class about all the other things you could be doing other than learning about the ancient Greeks when your teacher calls on you to answer a question. Once on the conveyor belt, our brain has about 18 seconds to use this information otherwise it will fall into an incinerator where it cannot be recalled from ever again. The conveyor belt is pretty small, it can only have 5 – 9 information “boxes” on it at one time.
Information falls onto the conveyor belt, either through our senses, like sight or sound, or internally from our own thoughts. A good analogy for short-term memory that I like to use is a conveyor belt moving along in your brain. Short-term memory is a form of memory which allows us to remember about 7 +/- 2 items for approximately 18 seconds. I’ll leave out procedural memory because Dory seems to have no problems with swimming!Ĭopyright: Disney/Pixar Short-term memory Procedural memory primarily has to do with motor movement, like riding a bike, throwing a ball, or swimming. A fourth type of memory, procedural memory, exists as well. Source: Disney/Pixar Different types of memoriesīefore getting into Dory’s short-term memory loss I think I should first explain different types of memories and how they work. There are three primary types of memory in the conventional sense of the word: short-term memory, working memory, and long-term memory. Through a fun filled adventure with help from old friends from the Finding Nemo, like Crush the turtle, and new friends, like Hank the Octopus, Dory sets out to find her parents. But, without robust memories, Dory has to rely on gut instincts to navigate back to where she thinks her parents may be. Some very old memories of Dory’s begin to come back to her and she feels an urge to leave the safety of the reef and seek out her parents across the sea. This is extremely difficult due to Dory’s short-term memory loss. Also, rather than Marlin trying to find Nemo again, Dory is trying to find her parents. Rather than following Marlin, Nemo’s dad, the movie follows Dory the Blue Tang who sufferers from short-term memory loss. Nemo is still a kid and going to school with Mr. Warning: Minor spoilers if you have not yet seen the movie! Summary of Finding Doryįinding Dory picks up a little while after Finding Nemo ended.
