In this channel, I try to explain some of the trickier concepts in psychology (and other sciences). The explanations aren't too dumbed down, not too high-brow -- they're just ok.

this video takes a look at the "yanni vs. laurel" audio illusion that was super popular in May 2018. it can be explained through categorical speech perception, one of the basic building blocks of how we acquire and understand spoken language.

this video covers THE MCGURK EFFECT, a strange phenomenon that occurs when we experience conflicting visual and auditory information. we'll cover the original paper (McGurk & Macdonald, 1976) along with a newer study that uncovers what's going on in the brain when we experience this effect (Beauchamp, Nath, & Pasalar, 2010). words & music: alex daniel danielcog.com

what's a "supertaster"? - ok science
Просмотров 3,2 тыс.7 лет назад
the TAS2R38 gene accounts for variations in taste buds, particularly for BITTER receptors. those that have more bitter receptors (about 15 - 20% of the population) are especially sensitive to things like coffee, wine, beer, or tonic water. these folks are known as SUPERTASTERS. this video talks a bit about the history, definition, and daily lives of supertasters. you can find some of the test-s...

Kind of reminds me of this whole trans thing. They call themselves this or that, but your eyes and ears say something else. That’s why it’s so absurd to hold misgendering against someone.
POV your ADHD cannot handle this at all
Thanks so much for this useful explanation ❤❤
thanks well explained
Thanks man! Keep at it, you're awesome!
Great video, nice exaples, well exlplained. but the background audio is irritating and has high volume. please focus on sound quality and music to match your presentation and explanation.
Great explanation, thank u!!!! and a veeeery cool way of explaining
Any ideas on why my boyfriend of 10+ years left me with no warning? He said it was because of my mental health. The crazy thing is he was best friends with a psychology professor and texted them every single day nonstop and even went out with them weekly to the movies. When I asked if he ever discussed my struggles with his psychology professor best friend he said no?? So crazy. People can really convince themselves they’re right to do anything. I was texting him, “I’m going to off myself” and he said “can you go buy some lingerie for our date?” When I had a psychotic episode he laughed at me. He plays bass and is a narcissist if that helps! Edit: PS we never fought and he was my best friend and I’m no contact with my family and he took everything from me. I was even the main financial provider.
bruh i am so sorry i hope youre doing better now
@@kanakparmanandani8914 that’s actually mega nice of you to reply to my crazy comment. I was really grieving when I posted this. I’m really glad you saw how much pain went into that and not just a psycho person. It means a lot this morning I was still crying over this. Your comment makes me feel better even though it was so simple and I don’t know you. I hope you have an amazing day
this video helped me understand this sososo much better than before thank you!!!!
Does anybody have a video of a man who has the ability to see in night vision? Is that a hoax?
The Me effect‽‽ 😂😂
What if you can concentrate on both simultanouesly?
Simple ,easy to understand help alot
Please can u send me the test as a pdf , for kids ( 3-6 ) years old please
intro got me
My professor put this in our material to go over and I really wish he hadn't. The concepts were explained really well but the music was too loud. The water sound actually hurt my ears but I couldn't turn it down because I couldn't hear the speech otherwise. This video definitely could have benefitted from better editing.
When I'm walking and stop to rest it appears as if the ground is stretching before me. I was told it is motion after effect. I rather enjoy it lol. It's not exactly bothersome.
The first few notes of the theme song. I thought Brittney was about to sing. 😆
I didn't notice the change in the shadow even with the 0.1 second flicker. I guess that means my sensory memory doesn't even last a tenth of a second.
I have a cognitive psychology exam tomorrow and this video was extremely helpful!
I even tried hearing yanni but all i can hear was laurel the whole time
never noticed the ice cube, just the lights flickering throughout the scene
I still hear "yearly" 🤣
thank yoou
TOTALLY unintelligible narration.
you shouldve had added a final example for that very last math part... i still dont understand how to get the "k" of something and how exactly do u multiply that w the stimilus strength
And what about the stick on the ground? That’s what I saw 😂
My problem with the first one is that I couldn’t remember any of the words cause my memory sucks. The words and numbers, I didn’t remember the numbers, just that one side was words and the other was numbers.
heard both at the same tiiime in all these cases bro
Looked liked interesting content but due to the back ground sounds, I hesitate to call it music, I was unable to concentrate. I must be the only one.
Me too to some extent
Thank you
2:00 AHHH, but did you also notice that the log lying on the ground, next to the shadow, ALSO disapeared?
A guy from 6 years ago saved my uni life. Thanks.
I hope he's doing well
I only heard Yanni, regardless of the frequency.
I haven't even finished the video yet but damn that's a cool intro!!
Thanks brother, for your easy to understand video.
Why are you talking much much much fast!!!!!!!!!!!!!!!!!
In the shining he also takes a scoop of nuts to eat, and there are still a few in the glass. Unless I’m mistaken then there are none in the next shot
OMG, your video is so much fun! Thank you😊
Awesome! Your explanation was very easy to follow. Thank you!
i saw the change in the first example but not the second 🤦🏾♀️
I had the opposite, didn’t see anything in the first but i did in the second
I saw those strawberries as _"largely a grey but with a tiny extra red colouration"_ (as though somebody added black to pink), and so, as with other optical "illusions" I've doubted before when in video, I checked it out. And they are not grey but instead they are exactly what I said they are. Et la, I took a screen-shot and put it in an art package software and used the colour picker. In more than one area _(such as the strawberry cleft in twain laid apon its back)_ there is slightly more red than other colours in the "grey". Video compression (such as 480p vs 1080p) will not sacrifice the same amount of black as other compressions. It's too "expensive" in the compression, such that the encoder discards it. You can essentially end up with a gaussian kernel density 'estimation' for a hot pixel, a bit like the visual effect of antialiasing at neighbour pixels. A bar in a histogram bin is essentially swapped for a hyperplane, and compressing down so you get some different magnitude or frequency. Before verifying as described, I was prepared to doubt my vison because it mostly looks grey as if they are not strawberries but face-hugger-xenomorph eggs or dea-sea mud. However, turns out, nope, it definitely has more red in some pixels in the spots I saw it before checking. Computer video compression messes with the optical illusions. I saw this with another video on the topic of the black and white squares. Same happened but instead of reds it was two different greys. Those types of photos are often jpeg known-quantity files witha give hash and the DCT (discrete cosine transform) has already been through it, but then by plonking it into a video the author is demanding of that image to go, yet again, through the DCT (sometimes more than once). And so something changes, be it YUV or luminosity or whatever the software has optimised for in whatever pass the encoding had in for it. Your patter was cool. The image simply is not what it claims though. This information is to help you. My comment has no hate in it and I do no harm. I am not appalled or afraid, boasting or envying or complaining... Just saying. Psalms23: Giving thanks and praise to the Lord and peace and love. Also, I'd say Matthew6.
It was like a light switch, depending which one I looked at the sound changed almost instantly. That's insane.
how did i end up here, i’m litterally 13. Great presentation tho 👍 explained it rlly good
which movies is it?
Thank you so much, Sir. You explained it clearly and more easily than my professor. 😁
I don't like the music that is distracting me a lot😱😱😱
Still am watching thank you so much

Hey just a random aside, but I have always heard that an accident with the chemical PTC at DuPont in the 1930’s is how people first realized that some folks had an intense reaction to the taste and others did not! Probably would have been a good idea to add, but either way you are a fantastic science communicator, I love your energy!!!!
