But when we close our eyes, how do we visualize what we have already seen?
A new study led by the University of Plymouth and the University of Essex investigated this issue and found that many adults refuse to imagine their vision as a flat image-instead seeing it as a fully processed, knowledge-filled image.
The researchers showed 58 adults two lines on the wall.
Although they were told that their judgment should be based on appearances (that is, the closer the line should be, the longer), about half of the participants thought the lines looked the same
This shows that even if the participants are clearly aware that the 2D image vision looks like they treat actual sensory input differently, there is considerable resistance to seeing the so-called "proximal representation" of the vision (how it appears before our brains have a chance Correct the relative size and distance)
The lead author of the study, Dr.
"The next question is, why do these people think like this?" Are they unable to think in 2D, or did they choose not to think? We cannot be sure, but there is an explanation that people resist the principle that vision is equivalent to a flat image— -"Corrected" vision is the only type of vision they can reasonably imagine
