Why, as we look from left to right, do objects in front of us not seem to move from right to left?

The assembly of geons into an object __________.

What mechanism seems to be mainly responsible for our ability to detect primitive features?

Some artists create paintings wherein the figure and the background relations are deliberately reversible and ambiguous. Such ambiguity illustrates which important general point about human perception?

One thing that seems clear is that vision is made possible by an intricate network of subsystems, each specialized for a particular kind of visual task and each working together. But with all these subsystems at work, how does one manage to create the impression of a cohesive and organized world? How does the brain reunify pieces of visual information that start out discrete? The difficulty in answering these questions is called __________.

Which area(s) of the cortex is (are) directly involved in processing visual information?

Francis has visual agnosia. He is looking at his cat, Fluffy. What will be most difficult for Francis?

Which of the following is an example of figure-ground perception?

Leo looks at an old photo of his family. At first, his feature detectors are triggered by horizontal and vertical lines; these detectors then trigger the next level of detectors and so on until he is able to perceive that the photo is of his family. This would be an example of __________.

Bert has just baked a large sheet of perfectly round, delicious cookies. When Bert leaves the room briefly, Cookie Monster takes a half-moon-shaped bite out of one of the cookies and replaces it into the array of cookies. Bert returns to the room and looks at the cookies, but misses the fact that Cookie Monster has taken a bite out of one of them.
