Very interesting. My favourite part of all this though is how she comes up with an actually reasonable sounding excuse for why she didn't draw the left, and she kind of refuses to acknowledge that she can't 'mentally see' it. That reasoning part is still very much intact even when she literally can't even draw a daisy properly.
This is very common in these types of illnesses, her brain refuses to send any signal at all to that section of it, which means she doesn't actually recognise that nothing is being sent, imagine being blind but your eyes dont send the signal to your brain to tell it they cant see anything
It's the same with everyone. If you had her condition you'd see things the way she sees them. It doesn't make her sad probably. It's just how our brain works. So fascinating tho!
What would happen if Peggy was asked to close her eyes, imagine a sunflower, and then draw the sunflower while keeping her eyes closed. Would she draw the sunflower which is complete inside her mind, or will she persist to draw an incomplete version of the sunflower?
J Spright I think an incomplete version will persist to be drawn. Even in her consciousness, when she thinks of the image, the left side is completely removed and the emptiness is ''filled'' by just attaching the two lose ends of the flower. (Like when you take a paper circle, remove one quarter and try to make the new ends meet). While this would result in a preposterous image in the real world; in her brain, it all makes sense.
She realises her mistake when pointed out! If her abstract reasoning is ok and she is aware of her condition, why can't she point this out to herself and realize her mistake..?
basically her brain was damaged so the visual part of her brain isn't sending signals to her brain that she can't see that side of the daisy, and as a result the conscious side of the brain has to convince herself she is seeing the whole daisy. the communication/speech part of the brain has to come up with a completely untrue response because there is no signals to for her to become consciously aware of what is happening.
@@zoejane1635I would say that more than a visual problem, it is an attention problem. At least, that's what the current updates interpretation is. She can't allocate attention to the left side of her body and environment, no matter what happens in the environment itself (e.g., if an apple falls to the left, your attention would be naturally caught by it, and you would look at it). But when they force her to pay attention, so allocate her attention voluntarily, then, the left field appears to her. Because, again, it's not a visual problem, that would be another condition, which is called emianopsia. All on all, a very interesting condition. Nonetheless, I hope this grandma managed to regain some lost ability, it has to be a struggle to live with...
Does anyone know that when after it was pointed out to her that she drew only half of the flower, would she be able to continue to draw the rest of it?
Yes! And in italian sinister is "sinistro" wich is the same word for "sinistra" wich means "left". Left is the part thosee patients neglect. Some hermeneutic interpretation of the condition consider this aspect :) they neglect the sinister in the world.
Hello, I work for Texas Woman's University in the Disability Services for Students office. One of our professors is using the following video as a part of their curriculum. Can you either upload accurate captions to this video to make them accessible to Deaf and Hard of Hearing people viewing the video, or will you give me permission to caption the video so that we can get this video captioned before the start of the fall semester? We are not able to use the auto-generated captions as they are not ADA-compliant. Thank you

😂😂😂 come on, you made laugh so pleasantly. Thank you. 😊
tell peggy turn the page upsided down when shes finished
Jay Seraphina 😂
It would actually be interesting to see if she figures out by herself of if you still have to point it out
I wanna give that poor old lady a hug

On repeat loll 😂

i feel sad for her...makes us realize how lucky we are ..

People... He meant we're lucky for having our capacities functioning normally...
Whos here from vsauce?
I'm here from Reddit

Ironically no
Will I'm not
thanks for posting! a great example for neuro/cognition students!
Absolutely fascinating
Great video and enough detail to help me understand! Thanks!
I surprised to hear from her that she got a problem and said it's very odd to not pay attention to left side.
I loved cognitive psych! ... yet another example of how amazing our brains are

hiiii

+J Spright neglect applies to mental images too
They do that with a daisy at 1:23, right?
you suffer off the same condition as Peggy.. but yours is more of an intelectual problem

Yeah it is
Anyone from Prof. Steve Joordens online classes?
yeah!

Yaaay Ramachandran! \o/
Does anyone know that when after it was pointed out to her that she drew only half of the flower, would she be able to continue to draw the rest of it?
maybe if you rotate the paper lol
He sounds like a black Sean Connery :)
What if we gave her a daisy flower with a broken or torn right side and told to draw it exactly as it is without rotating or touching it?
Sinister!
Yes! And in italian sinister is "sinistro" wich is the same word for "sinistra" wich means "left". Left is the part thosee patients neglect. Some hermeneutic interpretation of the condition consider this aspect :) they neglect the sinister in the world.
Subtle but major takeaway: Attention is intricately related to consciousness
Hi... Glad to see fellow Courserians
Wait, what if I have anosognosia but I don’t realize I have it. How can you tell if you are fine or it’s all an illusion
If you had it, your daily life would certainly be affected, and someone would have pointed it out by now
At 2:37 I was like "oh shit Liam Nesson is narrating this"
I was *NOT* expecting the guy to look like that at all :L
YES RAMACHANDRAN
I see Borat!
Hi Dr. Itaya students!
Allocentric neglect
And the daisy example is one of representation neglect
