1. Perception crash course
The process of organizing and interpreting information, enabling us to recognize meaningful objects and events.
mind illusions

3. Perceptual Ideas an illusion

4. Selective Attention
The focusing of conscious awareness on a particular stimulus.
cocktail party effect selective attention to one voice among many

5. Change Blindness Would you fall for that?

7. Top-Down Processing We perceive by filling the gaps in what we sense.
I _ant ch_co_ate ic_ cr_am.
Based on our experiences and schemas.
Perceptual Set – a mental predisposition; the experiences, assumptions, and expectations that influence our perception

10. Perceptual Adaptation inverted vision program 7: start @ 15:39
The ability to adjust to an artificially altered visual field

12. Gestalt Psychology
Gestalt – an organized whole; from German for “form” or “whole”
Gestalt psychologists emphasized the tendency to integrate pieces of information into a meaningful whole.
Gestalt Psychology says that we innately look at things in groups, not as isolated elements.
“The whole is greater than the sum of its parts.”

13. Grouping & Gestalt Psychology Khan Academy
Proximity - group objects that are close together as being part of same group
Similarity - objects similar in appearance are perceived as being part of same group
Continuity - objects that form a continuous form are perceived as same group
Connectedness – objects that are uniform and linked are perceived as single units
Closure - we fill gaps to create a whole or complete image
Closure

14. Figure Ground Relationship
Visually, our first perceptual decision is “What is the figure?” in the image and “What is the ground?” (background).
The figure ground relationship can also be applied as a principle of auditory perception.

15. Depth Perception Eleanor Gibson - Visual Cliff Experiment
If you are old enough to crawl, you are old enough to see depth perception.
We see depth by using two cues that researchers have put in two categories:
Monocular Cues
Binocular Cues

16. Sensory Restriction Blakemore & Cooper, 1970
Kittens raised without exposure to horizontal lines later had difficulty perceiving horizontal bars.

17. Binocular Cues Khan Academy
We need both of our eyes to use these cues.
Retinal Disparity - as an object comes closer to us, the differences in the images for our eyes becomes greater.
“finger sausage”
3-D movies
Convergence - as an object comes closer, our eyes have to come together to keep focused on the object

18. Monocular Cues khanacademy(start 2:00)
You really only need one eye to use these (used in art classes to show depth).
Linear Perspective
Interposition
Relative Size
Texture Gradient
Light / Shadowing

20. Motion Perception Stroboscopic Effect Phi Phenomenon
a rapid series of slightly varying images perceived as moving images (flip book, “old” movies)
Phi Phenomenon
illusion of movement created when two or more -----lights next to each other blink on and off

22. Constancy khanacademy(start @ 6:10)
Objects change in our eyes constantly as we or they move….but we are able to maintain content perception
Shape Constancy
Size Constancy
Color Constancy
Brightness Constancy
However, color and brightness also depends on context!

23. Parapsychology
the study of paranormal phenomena, including ESP and psychokinesis
ESP – extrasensory perception; perception outside of sensory perception
Telepathy
Clairvoyance
Precognition
