Sensation and Perception Vocab Quiz 3
14
absolute threshold: minimum magnitude of the stimulus that can be detected 50% of the time
rhodopsin: visual purple
difference threshold: minimum amount a stimulus must change in order for the change in sensation to be detected 50% of the time
Rods: photoreceptor, important for vision in dim light, located in the periphery of the retina
Weber fraction: the amount of the stimulation necessary to result in a “just noticeable difference” is a constant fraction of the stimulus intensity, Provided the answer to the “How much?” question
Cones: photoreceptor, color, photo pigments
JND: just noticeable difference
Sclera: white tough covering of the eye
fovea: structure in your retina is responsible for highly detailed vision
cornea: transparent covering, provides most 75% of light refraction ability/power
optic disk
: blind spot in the eye, where the optic nerve leaves the eye, located nasally
lens: thicker in middle and thinner on edges, can change shape
refraction: bending light rays
Gestalt principle: The whole is greater than the sum of the parts
Accommodation: changes shape to allow vision at varying differences
