STM, LTM, and Placing Orders

During Lesson 6 and 7 we discussed Short Term Memory (STM) and Long Term Memory (LTM). Typically, STM is capable of holding about five or nine items in its memory slot. If repeated multiple times, it’s usually stored in our LTM section of the brain. Along with this discussion, we were introduced to a Phonological Similarity test where each individual had to go through memorizing a series of randomly generated letters and try to remember the order in which they were given. STM and LTM play such a large role in our everyday lives. While it wasn’t until I had friends over and offered to buy them Starbucks that I realized my STM is quite shorter than I realized. It also made me recognize, with a simple everyday activity, just how common it is that we utilize both STM and LTM.

So it was a Sunday morning and I had company over. I decided to treat everyone to some coffee at a local Starbucks. Of course, no one wanted to come, but they all wanted coffee so I figured I’d take their orders and drive out on my own. While asking for their order I realized that after the fifth person, the previous orders were already forgotten. I quickly opted for everyone just to text me their orders since the only thing I remembered was my sister’s Grande Soy Mocha (hot) with whipped cream and my Grande Cinnamon Dolche latte with a single shot, hot as well, with whipped cream and no cinnamon on top. That’s when I stopped. I couldn’t remember everyone’s order, not even the simple tall Vanilla Bean Frap, but I surely remembered my complex order or my sister’s order as well.

So let’s talk about STM, short term memory only lasts about 30 seconds or so, and we only remember a few digits at that. The Phonological Test showed us that it’s easier for humans to remember the first and last words/letters in a list, but we easily forget everything in between, unless it’s repeated and then sent to our LTM category. Back to me, standing in my living room with five individuals staring me down all the while calling their orders out; I could only recall the last order I was given. And even with only one order successfully mentally jotted down, I personally knew that by the time I’ve arrived at the location, which was a 20-25 min drive, I would surely forget everything that was requested of me.

So why did I remember my complex order and my sister’s? LTM. Long term memory comes into play when items are repeated. Over the years I change my order up of course, but that’s not to say that my Cinnamon Dolche isn’t a classic favorite. And no matter how many times I get it, it’s always the same in that order I listed earlier (single shot, no cinnamon on top, Grande, whipped cream…yum!). After ordering it many times over the years, it’s no wonder I recalled it so easily compared to the randomized list of coffees my guests were giving me.

And so, in the end, it was interesting to realize how we utilize both types of memory in regular everyday activities. The only time I personally ever really thought about it was when I heard of people suffering from mental disabilities (strokes or accidents where there was brain injury). It never occurred to me how vital these two compartments of our brain are until these last few chapters and then recognizing it with something as simple as placing an order for my guests at a local Starbucks was an interesting experience.
