Across 5. The processes that allows us to detect color, motion, form and depth simultaneously (One word) 6. the principle that, to be perceived as different, two stimuli must differ by a given proportion or percentage 7. The adjustable opening in the center of the eye that allows light in; large in the dark, small in bright light 8. An illusion of movement created when two or more adjacent lights blink on and off in quick succession 13. The process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events 14. The central focal point in the retina, around with the eye's cones cluster 15. Depth cues that function within either eye alone 18. The light-sensitive inner surface of the eye that contains the cells which transduces light into neural energies 19. A short one of these in electromagnetic energy results in the perception of bluish colors, long ones resulting in red 20. The study of relationships between the physical characteristics of stimuli and our psychological experience of them 21. The activation, often unconsciously, of certain associations, thus predisposing one's perception, memory, or response 23. Retinal receptors that detect fine detail and allow color sensation 24. The ability to adjust to an artificially displaced or even inverted visual field

Down 1. According to the Young-Heimholtz Trichromatic Color Theory, the number of different color receptors we have in our retinas (spelled out) 2. The process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment 3. Tendencies to organize stimuli into meaningful groups - includes proximity, continuity and closure 4. German for "whole," this theory says our brain tends to integrate information into meaningful wholes 8. The tendency to perceive objects as unchanging 9. In the portion of our eye where the optic nerve leaves the eye, light is not processed by the retina, resulting in a _______. 10. The minimum stimulation needed to detect a particular stimulus 50% of the time 11. A mental predisposition to perceive one thing and not another 12. The process by which our two eyes each resolve the slight difference between their images, allowing for depth perception 16. The process by which we receive sensory information, transform it into neural impulses, and deliver it to our brain 17. Depth cues that rely on the use of two eyes 22. Retinal receptors that detect faint light, specifically, black, white and gray
