"Everything psychological is biological."
Episode 3 of Crash Course is, sadly, the one other topic of general psychology that I tend to hate. While I dislike learning about the scientific procedure and research methods, I might dislike learning about the biology even more. Axons, neurons, dendrites, action potentials... this episode goes through all of this that I have been forced to go through over and over (namely action potentials) that make me simultaneously groan because I've learned this in every single PSY course and also because it is still the most difficult stuff for me to memorize.
Despite the greatness that is Crash Course, I still found myself zoning out multiple times during this video, which already makes me sad because this video deserves better. Although, my favourite part of the video would have to be Hank describing the difference in communication between the nervous system and the endocrine system in a very funny and useful metaphor:
"If the nervous system wants to get in touch with you, it sends a text. But if the endocrine system wants to send you a message, it will lick the stamp, write your address... and then a note... on pen, on paper... fold it up, and then mail it to you... via post office."
My LEAST FAVOURITE PART of the video was when they decided to put in a half-second scream randomly near the end of the video to demonstrate you not being able to control when you get scared, but your body reacts for you in different ways. Wow, if I was sleeping before, that definitely woke me up. Thanks, Hank. Thanks a lot.
