  • Thanks for having me on the show. Hopefully, it was sufficiently interesting/helpful.
  • @jopo7996
    This guy is so good at this, he's actually wearing a red plaid shirt.
  • My guy treated it like a speedrun while still being incredibly informative and concise. Thanks so much!
  • @mallie.b
    Pascal!! The best professor I had at NYU! Can’t express in words how happy I am to see him in-front of more eyes. The best of the best
  • @Quinnzel101
    I like how he said he was going to ruin ducks for everyone and then made them 10x better.
  • @rubycat23
    I have ALWAYS seen the dress as black & blue. Never understood how anyone could see different. To find out only night owls see black & blue is really interesting because I am an EXTREME night owl with a severe circadian rhythm sleep disorder. Thank you for such a fascinating vid. I'd like to see more like this.
  • @nvrt7209
    I could never see the dress as black and blue until this video. I guess him holding up the dress first fixed my brain for a couple seconds and I could see the image as black and blue. Then half a second later I remembered what the white and gold "version" in my head looked like and it changed back to white and gold immediately. But now I can kinda trick my brain into seeing it as black and blue and it's the coolest thing I've ever seen.

    One of my favorite instructors of all time. When I was a student at NYU, I took his sensation and perception class and it altered my entire life trajectory. Watching this was a fantastic reminder of how efficiently he communicates these sometimes dense concepts merely by exuding his palpable passion about how insightful these illusions can be with regards to the way the brain is creating models of external inputs.
  • Love how he is willing to admit that there are things we still don't know. Definitely am important thing to communicate: there are always more things to discover
  • @LFresh86
    Came for the dress, stayed for the knowledge. This was awesome 🙌🏾
  • This was the best episode ever. This professor was the best at breaking it down and not making me feel like I either NEED a PHD to understand nor need a nappy time afterwards.
  • @anshmundra02
    had him as my prof last sem for my data science class. hands down, he is one of the best at NYU. his passion for teaching and learning shines through in every second.
  • @AnkitaBhanot
    My eyes lit up seeing Pascal in this video. I took two classes with him at NYU and they were delightful. He somehow made advanced statistics interesting and had such a bright and vibrant personality! His research on psychopaths and music is fascinating. Love seeing you doing well, Pascal! 😊

    20:40 this is why some stores have bigger shopping carts, people tend to buy more when they don't think they're buying that much.
  • This should be a series... like the one with the body language guy. The man knows his stuff.
  • I wish these episodes were an hour long of these experts sharing their knowledge, I can never get enough of them!
  • I came for the dress question but found myself engrossed in this ENTIRE video! I loved this way of explaining it so it’s easy to understand.
  • @TheRavenfish9
    On the blue dress part: Interesting that when the actual dress was in the shot, I saw the dress as black and blue, but when it cut to a close up it flipped to white and gold. So cool. And I love that fact about morning or night people! That explains so much. Fascinating video! Thanks so much for all this really cool information.
