A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

This just happened to me the other night.

I'm in a dispersed camping spot in a National Forest. It's not crowded. I go to sleep around 9:30PM and wake up at 4:30AM to someone parked right next to me. There's no trees between us and no possible way that they did not see my car.

As I drive out of the forest I pass dozens of empty spots.

This has happened to me twice. Who are the people who do this? There's no rational explanation for it.

I wouldn't judge someone who shows up to a campground at 430 am too harshly...

They're probably running on pure lizard brain at that point.

Like, depending on your definitional of rational, there was/is a reason for this behavior, but it's not like someone intentionally decides to do it. It's just autopilot.

A lot of what we do is just autopilot and rationalizing it later. Shits crazy interesting, but we can't really study it because it's not ethical to just cut people's brains in half for no reason other than to gain knowledge. And there was only a brief period it was a valid medical treatment for things like epilepsy.

Sperry performed another similar experiment in humans to further study the ability of the right hemisphere to recognize words. During that experiment, Sperry asked volunteers to place their left hand into a box with different tools that they could not see. After that, the participants saw a word that described one of the objects in the box in their left field of view only. Sperry noted that most participants then picked up the needed object from the box without seeing it, but if Sperry asked them for the name of the object, they could not say it and they did not know why they were holding that object. That led Sperry to conclude that the right hemisphere had some language recognition ability, but no speech articulation, which meant that the right hemisphere could recognize or read a word, but it could not pronounce that word, so the person would not be able to say it or know what it was.

In his last series of experiments in humans, Sperry showed one object to the right eye of the participants and another object to their left eye. Sperry asked the volunteers to draw what they saw with their left hand only, with closed eyes. All the participants drew the object that they saw with their left eye, controlled by the right hemisphere, and described the object that they saw with their right eye, controlled by the left hemisphere. That supported Sperry´s hypothesis that the hemispheres of brain functioned separately as two different brains and did not acknowledge the existence of the other hemisphere, as the description of the object did not match the drawing. Sperry concluded that even though there were no apparent signs of disability in people with a severed corpus callosum, the hemispheres did not communicate, so it compromised the full function of the brain.
