PSYCH 100 Lecture 8: Perceptual Organization
Document Summary
To understand how perception is organized, illusions provide good examples. Which segment is longer ab or bc?-yellow. What is wrong with this picture?- skewed perspective makes one look bigger than the other. Our brain must decide what is figure and ground. Then it has to decide which part of an object goes with which part. Depth perception enables us to judge distances. Image on each retina is slightly different. When brain combines images, sees things in 3d. Our eyes move together to focus on something close, farther apart for distant objects. Monocular cues - require only one eye. If two objects are similar in size, one that casts a smaller retinal image as farther away. One object blocks our view of another, the object that is blocking closer. Parallel lines appear to converge with distance. The more the lines converge, the greater their perceived distance. We see fewer details (texture) the farther an object is from us.
