Answer to Question 1
Disturbance in the temporal region of the cortex can lead to simultagnosia. In simultagnosia, an individual is unable to pay attention to more than one object at a time.
Answer to Question 2
CUES FOR DEPTH PERCEPTION APPEARS CLOSER APPEARS FARTHER AWAY
Texture gradients Larger grains, farther apart Smaller grains, closer together
Relative size Bigger Smaller
Interposition Partially obscures other object Is partially obscured by other object
Linear perspective Apparently parallel lines seem to diverge as they move away from the horizon Apparently parallel lines seem to converge as they approach the horizon
Aerial perspective Images seem crisper, more clearly delineated Images seem fuzzier, less clearly delineated
Location in the picture plane Above the horizon, objects are higher in the picture plane; below the horizon, objects are lower in the picture plane Above the horizon, objects are lower in the picture plane; below the horizon, objects are higher in the picture plane
Motion parallax Objects approaching get larger at an ever-increasing speed (i.e., big and moving quickly closer) Objects departing get smaller at an ever-decreasing speed (i.e., small and moving slowly farther away)
