Across
  1. 4. the principle that, to be perceived as different, two stimuli must differ by a given proportion or percentage
  2. 6. German for "whole," this theory says our brain tends to integrate information into meaningful wholes
  3. 7. Retinal receptors that detect fine detail and allow color sensation
  4. 9. The activation, often unconsciously, of certain associations, thus predisposing one's perception, memory, or response
  5. 12. The ability to adjust to an artificially displaced or even inverted visual field
  6. 14. The minimum stimulation needed to detect a particular stimulus 50% of the time
  7. 18. An illusion of movement created when two or more adjacent lights blink on and off in quick succession
  8. 20. Retinal receptors that detect faint light, specifically, black, white and gray
  9. 21. Tendencies to organize stimuli into meaningful groups - includes proximity, continuity and closure
  10. 22. The process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events
Down
  1. 1. According to the Young-Heimholtz Trichromatic Color Theory, the number of different color receptors we have in our retinas (spelled out)
  2. 2. A mental predisposition to perceive one thing and not another (two words, no space)
  3. 3. The process by which our two eyes each resolve the slight difference between their images, allowing for depth perception
  4. 5. The processing that allows us to detect color, motion, form and depth simultaneously (One word)
  5. 8. The light-sensitive inner surface of the eye that contains the cells which transduces light into neural energies
  6. 10. The study of relationships between the physical characteristics of stimuli and our psychological experience of them
  7. 11. Depth cues that function within either eye alone
  8. 12. The tendency to perceive objects as unchanging
  9. 13. The process by which we receive sensory information, transform it into neural impulses, and deliver it to our brain
  10. 15. The process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment
  11. 16. A short one of these in electromagnetic energy results in the perception of bluish colors, long ones resulting in red
  12. 17. Depth cues that rely on the use of two eyes
  13. 19. The adjustable opening in the center of the eye that allows light in; large in the dark, small in bright light
