The guy who 'mistook his wife for a hat' - people who have perfect vision but can't interpret what they're seeing... can they read?

ahh sorry my mind is a bit drifty today... i can't believe i confused that

Okay so I'm not 100% sure on this but I am pretty sure that they would NOT have the capacity to read. Before information is transmitted to Wernicke's area for comprehension purposes, the individual would still need to have a fully functioning visual cortex in order to process the information visually. In other words, visual interpretation would need to occur before transmission to Wernicke's area. As the individual cannot interpret visual information, Wernicke's area would be receiving distorted information (hence, the person can't read).

daniel99:
No they wouldnt be able to. Like your example lol, they would see writing as something else e.g. a hat?

jess3254:
Thanks Nick and Daniel :) Yeah, that sounds about right.

daniel99:
Sorry, but when i posted I hadnt done chapter 2 yet.

I think if damage is done to the visual cortex you cannot read at all, as you cannot see lol???

BTW, when you said about the man seeing his wife as a hat are you referring to synaesthesia, which is a codition where people see noise as colours and objects as different things. e.g. a person as a hat?

jess3254:
Yes, well, damage to the visual cortex can cause blindness.

However, damage to the Primary Visual association areas can produce varying amounts of difficulty in perceiving shapes and objects. I was wondering whether these individuals experience inability to read, considering.
