  8. What do you see? Why? What is the Gestalt principle behind your perception?

  9. Don’t say it out loud!! How does top-down processing relate your perception of this image?

  10. Dissimilarity

  11. We live in a 3D world—How does your brain know this?Visual Depth Cues 3D with 1 eye • Monocular cues • Motion parallax video clip

  12. Which of the following rules of monocular cues did the artist use to help us perceive depth in this 2 dimensional image? linear perspective interposition texture gradient shadows aerial perspective (AKA relative clarity) elevation (AKA relative height) relative size

  13. Which of the following rules of monocular cues did the artist use to help us perceive depth in this 2 dimensional image? linear perspective interposition texture gradient shadows aerial perspective elevation relative size

  14. Which of the following rules of monocular cues did the artist use to help us perceive depth in this 2 dimensional image? linear perspective interposition texture gradient shadows aerial perspective elevation relative size

  15. Which of the following rules of monocular cues did the artist use to help us perceive depth in this 2 dimensional image? linear perspective interposition texture gradient shadows aerial perspective elevation relative size

  16. 3D with 2 eyes • Binocular cues • Retinal disparity • Floating hot dog finger! Can you explain the phenomenon? • Oculomotor (proprioceptive) cues Your brain interprets motion of muscle movement as depth • convergence and vergence Feel the muscles move! Brain detects inwards strain as ____________? • object is closer!! • accomodation= lens changes shape as you fixate on objects--more curvature for close objects, less for far away • You don’t consciously control accomodation.

  17. Human factors—what psych majors can do besides clinical psych Trapped between doors

  18. More really cool stuff! • Perception of motion—the phi phenomenon Video clip • Stroop effect class demo • Why does it happen? • Speed of Processing Theory: the interference occurs because words are read faster than colors are named or items are counted. • Selective Attention Theory: the interference occurs because naming colors or counting items requires more attention than reading words.

  19. How your sensory organs work: The eye and the ear • Cow eye dissection • Video clip: how the eye works • Video clip Hearing

  20. How the other senses work • Video clip olfaction • Video clip taste and smell • So you think you really need eyes to “see”? • video clip of the blind painter • Video clip: bionic eyes • Echolocation part 1, part 2 • Pain—why do we feel it and why do we sometimes not? • Video clip woman falls off cliff • Phantom limb video clip

  21. Vestibular and kinesthesis demo • Nystagmus demo with 1 volunteer and a roving pair of eyes • All: • Stand on 1 foot for 30 seconds. How well can you maintain balance? • Stand on 1 foot for 30 seconds with eyes closed. How well can you maintain balance? What is helping your body maintain balance? • Spin until I tell you to stop. Close your eyes and balance on one foot. Why can’t you? • ALL: • Stand on right foot with left foot tucked behind right leg. • Close your left eye and direct your fovea at something with your right eye. • Gently apply pressure inwardly on your right eyelid so that you are forcing your eyeball towards your nose while maintaining focus on the object

  22. Are you field dependent or field independent? • Field dependent people rely on visual cues to create sense of balance • Field independent people rely on gravity/vestibular cues to find sense of balance So what? • Field dependent people tend to be more extroverted, emotionally open and good at reading social cues • Field independent people tend to be more introverted, cerebral, and science/math oriented
