Does Psychology Exist Outside of the Social Realm?
A question that was requested I answer.
Overall, yes, it does—at least in my opinion. Forgive me, I am entirely biased. Bias? That in and of itself is psychology, no? Anything outside of my mind or within it has an impact on my brain and how I process things.
If there was one single individual in his lonesome on the Earth with no person or animal to interact with, it still remains psychological, because everything is filtered through the mind. Your thoughts on the sky, the trees, and its effect on you.
Granted, a human would go insane without social interaction. Eventually, the brain would construct itself a realm of social interaction. For all you know, it could start calling trees their friend. Ready to be a tree hugger? A study in the past I did research on was conducted by two scientists who sat in caves, both for separate amounts of time. The one who stayed isolated longer was much more deeply impacted by the traumatic experience. He'd made the rats skittering around in the cave his friend, talked to them as if they were people, and lost all concept of time. He also slept for 2-3 days at a time, feeling as though it had been a normal eight-hour slumber.
I can't imagine how humans would be today if they were all isolated from social interaction, but nonetheless, psychology would not cease to exist unless creatures themselves ceased to exist.
In conclusion, a human can still experience negative emotions or overly positive ones. In fact, social interactions are likely what's keeping a person's sanity intact. I believe that psychology and how susceptible your brain is to outer stimuli is significantly higher than it would be without social interactions.
