hemineglect

Question 9

The problem of determining which bit of the image in the left eye should be matched with which bit of image in the right eye is known as the

correspondence problem
disparity paradox
motion paradox
convergence problem

Answer 9

correspondence problem

Question 10

two lines in an upside-down V, with a line horizontal near the tip and another one near the end

In this figure, why might the top horizontal line appear to be longer than the bottom line?

Linear perspective makes the top line appear farther away, which means it must be longer

Binocular disparity makes the top line appear farther away, which means it must be longer

Relative height makes the top line appear closer, which means it must be longer

Relative size makes the top line appear closer, which means it must be longer

Answer 10

Linear perspective makes the top line appear farther away, which means it must be longer
