What is responsible for depth perception?

Question

A) thalamus
B) binocular cues
C)retinal disparity
D)All but one of the above

how do you all know this stuff
what are retinal disparity and binocular cues? What is the thalamus responsible for?

Answer 1

binocular cues (things like color and size of what you're looking at, placement of objects. if you are looking at a candle that is behind another candle, you assume it is further away from you) and retinal disparity (your eyes are in different places and both receive different pictures, and because of the difference, your mind works out a comparison in order to find the relative placement of an object) are both responsible for depth perception, so the answer is D, all but one. your thalamus basically relays information to its respective processing center in the brain, so beyond passing on visual information, its not really responsible for depth perception

Answer 2

None of your choices are correct. Depth perception is a learned perception, some people don’t have it, even if they have two eye. Pygmies, don’t have it. This is because they don’t ever see anything more than few feet away. They have all the same binocular cues everyone else has, but when people without depth perception are in an environment where something will occur, like an object getting bigger the closer you get, it meaningless to them. In fact, they may not understand what is going on, and get frightened. Similarly people who lose an eye still have depth perception, almost the same as before, because they already learned what they need to know to figure out how far away something it. Depth perception is a just that, a perception. It is something that is learned.

While binocular clues and steropsis may help us get the information needed to learn depth perception, they are not responsible for it. That is like claiming that hearing is responsible for distinguishing sounds. Hearing gets noise, it is up to you to break that apart into sounds. Just like with vision, we do this but not always correctly, or perfectly. Our threshold for sounds for example are with in several fractions of a second of the actual sound. That is a fundamental aspect of linguistics (and cognitive psychology), and this is a fundamental aspect of cognitive psychology.

However, since the aforementioned research is ignored along with logic and common sense, the correct answer for your question is D, depth perception is “caused by” binocular vision and steropsis (retinal disparity). Since many psychologists follow the logical fallacy that the modes of transfer are the information itself.

I don't have the link to what I was talking about the pygmies, if you care you can contact me and I can find. Same with the linguistics and hearing. Although, since this is obviously for school, your teacher should know about the pygmies experiment and should be able to address, right or wrong, my claims.

Answer 3

binocular cues.
