Can a blind person?

[iBrezeeh]

Can a naturally blind person, who for some reason gets eyesight, differentiate between cube and ball just by seeing it?
He has felt both forms before, but now he can only look at them without feeling them. Could he tell what's what?

P.S. It doesn't care if he was told (while being blind) if what he's holding is a ball or a cube, only thing that matters is the present in which he can see for the first time.

 

[Mellow]

I'm pretty sure they would

 

[Osmon]

Legally blind or . . . ?

How can you drive a getaway car when you're legally blind . . . POP HOLD IT DOWN ! PIMP SQUAD BABEY FOH LIFEE !

 

[Pumpkin Ninja]

Not too sure. I think they'd be able to.

 

[Your Creepy Stalker]

Yes, they're very different shapes. The only way he would think the cube has round edges is if he had never felt the shapes before.

OT: Probably. Since the cube has pointy edges, it would be kind of easy to identify the shape with the edges.

 

[iBrezeeh]

I'll point it out again. The person has never seen anything before. He does not know what edges are, nor what's pointy, etc.

 

[Multiply]

If he has felt the shapes he'll know the difference if he sees them.

 

[Alfred Pennyworth]

I'm not so sure. Normal ppl associate the properties of a shape with their visual memories so just by looking at a certain shape they can figure out how it feels. Assuming blind ppl learn the same way,I doubt they can tell which one has a sharp edge and which doesn't just by looking at them for the 1st time

 

[Stant]

obviously.

 

[ChicagoJhawk]

Once he feels a corner it's all gg for the cube

 

[Jin]

TBH, I'm not really sure. Supposing he felt the edges, how would be able to identify and tell that those edges, when he has never seen anything in his life ...
He doesn't know how edges and flat surfaces look like, so it's possible that he can't tell which is which.

 

[Jack Spicer]

Not sure. I'm not a blind person who gained sight, so I don't know.

 

[Ansatsuken]

I think they still can recognize the shapes after the gain sight. Even though they couldnt see but they have memory and sense/touch. The info they stored after learning the shape of objects when they still blind could help them to identify the objects.

 

[Nick01]

If he/she knows the definition of what is a cube and a ball, then he/she should be able to tell.

A better question is... how do they know when to stop wiping?

These.
It's said no matter how hard you try to explain color to someone, they can never imagine
it- same should apply to this. The person wouldn't know it at a first glance because the
feel itself corresponds to the object(sight), sure you could distinguish and imagine the shape of
the object you felt takes, but that's only because you've had experience with it throughout
your entire life.

Though the blind person has no experience correlating what's seen to what's felt, because
they've never seen a thing and have had no way of telling the appearance of "sharp."

It's kinda like deciding what objects in front of you caused the sound you heard,
but the problem is you've never seen what caused the sound, nor have you ever
seen these objects before.

A better question is how often do they rub the toilet paper they sniff onto their nose?

 

[6ari8]

I don't think so. I doubt they'd even be able to grasp depth if it was their first time seeing. They maight see the ball as a circle and the cube as a box.

 

[Karna]

Yes, their mind would probably associate the sense of touch with other senses, they may not have sight by birth but evolutionary they have the same brain, all humans can think of what a person may look like from voice, weight from footsteps etc, what's to say they can't tell shape from touch? With some trouble I would say yes, but it's just a guess.

 

[Excālibur1]

I believe they will be able to differentiate between the two shapes. Touch and sound is their most important thing and they seem to be highly developed in case of blind people. So they can kind of get an idea of what the object's shape is like which means that they can differentiate.
