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