A 2012 Northwestern study investigating memory concluded that memory is like the telephone game. When you remember something, you’re actually not recalling the original event. Instead, you’re remembering what you remembered from your last recall of this memory.
What does this mean for memory? Not only does it explain a cause of false memories, but this phenomenon can be helpful in treating patients with PTSD, which allows memories to be “adjusted” by healthcare professionals.
When you remember something, you’re actually remembering the last time you remembered it.
As I thought about this more, I wondered — what actually happens when you remember a memory over and over and over again, recursively? What does that memory become? Do the forces of entropy and chaos reduce the memory to an empty void? Or, since memories are always filtered through your brain, perhaps your personality, internal beliefs, and worldview tint the memory, making it uniquely yours.
I wanted to investigate this recursive phenomenon more. A friend showed me Alvin Lucier’s “I Am Sitting in a Room”, an audio clip of a recording of a recording of a recording, etc. which ultimately reduces the entire audio to the room’s resonant harmonies.
Then I thought of a visual analogy: taking a picture of a picture, over and over again, and observing the result. Below is the photoshoot for a picture of Ted & Wally’s ice cream taken in Omaha, NE.
I used my iPhone 6s Plus to take the pictures, and my MacBook Pro 15 inch with Retina Display for displaying the rendered images. I mounted the iPhone 6s Plus with the Zilu Universal Car Phone Mount on a rotating small mirror, so that I could adjust the positioning of the camera precisely.
After taking a picture from my iPhone, IFTTT (link to the specific applet) automatically backed up the photos to a specific Google Drive folder, which I then opened on my computer to take the next picture.
When each photo is taken, there are small perturbations that slightly mutate the image:
This experiment is obviously not an accurate representation of exactly how the brain deals with memories, but an interesting thought experiment and investigation into the mutating forces of recursion and entropy.
It’s beautiful and fascinating to see the RGB colors of the computer screen come to life in the imagery, and the transformation of the image to the blobs is mesmerizing. For me, it’s a reminder that, despite the “destructive” nature of entropy, there’s such beauty in chaos.
The magnification of even the slightest perturbations was remarkable. In this ice cream photoshoot, my camera was very slightly tilted to the right, so that the left side of the image would get cut off. This effect compounded and eventually caused the whole subject of the photo to shift to the left. In memories, a similar effect occurs — a subtle negative thought or suspicion can compound over and over again, consuming the memory itself.
What other natural processes could this recursive photography symbolize?
I was curious to check out this effect on other types of subjects. I noticed that the colors still strongly trend toward RGB values. Quite fascinating to see my own face morph into a beautiful array of colors.
In this example, I really wanted to investigate the final equilibrium of the photo — does it ever reach a point where it stops changing? This photoshoot took the longest, but I eventually got to a point where I viewed a plain blue screen, which, after several photos, stopped changing.
What is the “final equilibrium” of our memories?
