Exam 3: Visual Perception

Shadowing can provide a cue for depth. For example, if a shadow appears on the bottom of a circle, the object appears convex. However, if the shadow appears on the top of the object, it appears concave. This happens because

Ganglion cells A, B, and C are next to each other in the retina and inhibit each other laterally. If light is hitting the entire receptive fields of A and B, but only partially hitting the receptive field of C, what will happen?

The blockage of one's view by another object can provide information about depth perception. This is termed

The importance of vision for humans is reflected in the

Some people have sustained brain damage and lost the ability to identify color. Other people sustained damage to a different area of the brain and lost the ability to detect motion. What does this indicate about our visual system?

________ cells in the LGN are specialized for spatial analysis and form detection, whereas ________ cells are specialized for the detection of motion and depth.

Molly went to the mall and parked her red car under a tree. When she returned to her car a few hours later, only half of the car was still in the shade. How will Molly perceive this situation?

A researcher has identified the receptive field for a neuron and has determined that the receptive field has a center-surround organization. If the researcher were to shine light into the entire receptive field, including both the center and the surrounding areas, we would expect the neuron to

Parvo cells are similar to magno cells in what way?

Which of the following statements about the visual stimulus, light, is FALSE?

The specialization evident in visual processing shows that

Jose is walking toward Dan, who is standing still. As Dan watches Jose move toward him, a series of physical and perceptual events will occur. Which of the following is NOT one of those events?

Through single-cell recordings, researchers have identified the ________ neurons in the visual system.

Cells detecting the boundary of a surface are subject to less lateral inhibition than cells detecting the center of the same surface. This leads to an effect called

Human brains have a distinct division-of-labor strategy. Each task is achieved as a result of multiple brain areas working together. But the work of the various parts of the brain must be compiled into a finished whole. The issue of how this reassembly works is referred to as the

Pick one of the ambiguous figures that was mentioned in the chapter. Describe the illusion and why it occurs. Make sure to differentiate between the role the stimulus plays and the role the interpreter plays in the illusion.

Which of the following statements about the retina is FALSE?

Which of the following does NOT provide an example for parallel processing in the visual system?

Which of the following is NOT considered a monocular cue for depth perception?

Which of the following would NOT be considered part of the fovea?
