Just what is the difference between sensing and perceiving? And how does vision actually work? And what does this have to do with a Corgi? In this episode of Crash Course Psychology, Hank takes us on a journey through the brain to better explain these and other concepts. Plus, you know, CORGI!

    That's right, I am your average binge watching crash course kid a night before AP psych exam. Are you guys with me?!!
  • I am dying right because i'm swamped with Psychology homework, but that corgi just made me feel so much better. I vote to have the Corgi in every crash course video
  • @cianodwyer5144
    Someone, somewhere realized they were color blind while watching this video lol
  • @a_Rand0m_Guy
    i love the absolute randomness of the sherbert part like that has nothing to do with psychology and almost nothing to do with the video but they invluded it anyway
  • You explained waves better in 30 seconds than my physics teacher did in 47 minutes. And you did it in a psychology video. I'm impressed.
  • @Kissarai
    I had to rewatch some of that. When the corgi showed up all my attention was wrapped up in "OMG OMG OMG OMG SO CUTE CAN'T HANDLE OMG CUTE."

    "Someone just told me the word 'sherbert' doesn't exist." "His name is Michael Aranda and he's a dumbhead." "ASK GOOGLE ABOUT SHERBERT!" I love Hank Green.

    I have a Bachelor's degree in Psychology, and I am amazed by how little I learned about neurology and physiology. Hank's teaching me more about these things than my college education did. Go higher education! Oh, and thanks Hank!
  • Funny thing, my native language is spanish, yet thanks to this courses I know a lot of words in English that I have no idea in Spanish
  • @danspearo6893
    Understanding perception from lecture = no. Understanding perception from psychology crash course = yes! When are you guys making more videos/lessons? So helpful, thank you!!
  • @MsKeksPudding
    I love how we're actually using his as educational material in our Psychology Bachelor course! Nice explanations!
  • @nine49four
    I'm studying psychology and the topics of these videos coincide with the topics I'm learning at university. I'm paying thousands of dollars for this material at university, yet your videos are better. Love it.
  • @simplymaci
    Idk who's more precious, the corgi or Hank Green 😂
  • @sithys
    This video is so interesting, I can't wait to learn more about...... THAT CORGI LOOKS SO HAPPY.
  • That dog is so fucking confused. The whole time he was trying to figure out wtf Hank was doing with his hands.
  • @DannyMercer1993
    As an anatomist, can I just say that this was brilliant.  The calibre of the scientific content, friendly "layman" presentation, and fabulous animation is how things should be taught in this age.  Its just ace :P 
  • @ES-xx2jq
    I've spent a week learning this stuff for a university exam next week and you just give me all of it in 10 minutes. The more I learn the more I appreciate the quality of crash course😍
