I got a D in college Philosophy (I didn't have a clue what I was doing). Today. (53 years later) I'd probably ace the class unless they flunked me for disagreeing with their hypotheticals. lol
I minored in Industrial Psychology, and had to pick a couple of electives. One that I chose was called Cognition. It was of how our mind works. I thought it might be interesting, and it was. It was strictly science things on how our brain works, like memory, etc. One of the reasons why phone numbers were put in 7 digits was because our short term memory stores things into long-term memory more easily as sets of 7.
One of the things I didn't believe at first, was how not everyone has the natural ability for abstract thinking. They referenced an experiment (which was made a movie), where they brought in a test subjects, one at a time, and set them before this table-panel of a row of toggle switches with voltmeters. They were told the test involved asking the subject in a back room on headphones test questions, and for each one missed, they were to flip a toggle switch and a shock would be administered. They were told to go through the test and continue through the switches as needed, each next switch adding more voltage than the last. The actual receiver was an actor who only play-shouted like he was being shocked.
They tested 3 subject Categories:
1. the first category were those who went through the whole test without any remorse or questioning, shocking the receiver as each question was missed.
2. the second group started, but after just a little into the test, turned and showed concern about the guy on the receiving end. The instructor then brow-beat the person to continue, and they did, went through the whole test like the first category.
3. when those in the third category were simply revealed about that the guy in the back room would receive a shock for missing a question, the subject became irate at the experiment, and refused to participate.
They also tested each Category's ability for abstract thinking:
1. the first category, that showed no moral sense, tested lowest on the ability to abstract think.
2. the second category, which showed some sense of moral code, but gave in by a little prodding, show some ability for abstract thinking.
3. the third category which completely refused to participate tested the highest in the ability to abstract think.
They also proposed that folks who tested low on abstract thinking often have a lack of ability to visualize things in their mind.
I didn't really believe it.
Then when I worked as a craftsman mechanic, and knew a couple of pipefitters, I noticed one of them did all the trigonometry layouts, and the other did all the welding. So I asked why. The one doing all the welding said he could not 'see it'. He claimed he could not visualize to do the pipe layouts of angles and such. So I asked if he could visualize period, and he said no.
