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