Study Notes
Vision and Color Perception
- Shortest wavelengths of visible light in daylight appear red (False).
- Iris controls the light entering the eye (True).
- Pathway from retina to brain: rods and cones → bipolar cells → ganglion cells → optic nerve (True).
- Trichromatic theory of color vision does not explain color blindness or afterimages (True).
- Red-green color blindness results in seeing blues, yellows, and grays.
Opponent-Process Theory
- Opponent-process theory identifies correct opposing color pairs: red vs. green, blue vs. yellow.
- Staring at red and then white leads to seeing green, supporting opponent-process theory.
Sensation and Perception
- Perception is interpreting sensations meaningfully.
- Bottom-up processing involves analyzing smaller features to create a complete perception, initiated by stimulus.
Auditory Perception
- Average threshold for human hearing: a ticking watch heard from 20 feet under quiet conditions.
- The hammer (malleus) connects to the eardrum; the stirrup (stapes) connects to the oval window.
Other Key Concepts
- Visual accommodation refers to the lens changing shape to focus on images.
- The cornea is the clear protective coating at the front of the eye.
- The eardrum is also known as the tympanic membrane.
- Binocular disparity refers to the slightly different images each eye perceives.
- Gate-control theory of pain suggests pain signals pass through a "doorway" in the spinal cord.
- Proximity is the tendency to group nearby objects together.
