Document Summary
Psych 7a - lecture 6 - sensation and perception (cont. ) Transduction converting one form of energy to another. With regards to sensation, transduction means converting stimulus energies (sights, sounds, etc), into neural impulses that our brain can interpret. Hue (color) determined by wavelength - the distance from one wave peak to the next visible light between 400-700 nm. Accommodation process by which the lens changes shape focuses incoming rays onto retina light-sensitive inner surface onto which light rays focus. We have a blind spot where the optic nerve exits each eye. The optic nerve leaves the eye on the nasal side of the eye, causing a blind spot in the left visual field for our left eye and our right visual field for our right eye. However, we"re normally not aware of the blind spot. The periphery contains all of the rods, but many cones as well. Cones are capable of higher resolution than rods.
