chapter 3 sensation and perception


undefined, object
copy deck
Theory that different cones are sensitive to particular colors in the retina (blue, red, green)
trichromatic theory
theory that 3 kinds of cells respond by increasing or decreasing their rate of firing when different colors are present
opponent process theory
light-sensitive receptor cells in the retina that look like slender cylinders and allos the eye to respond to as few as 5 photons of light
light-sensitive receptor cells in the retina that enable humans to see color and fine detail in adequate light but do not function in very dim ligth
visual depth cues that depends on both eyes and one eye
monocular and binocular depth cues
using a part to get to the whole
bottom-up processing
using the whole, or previous knowledge, to get to its parts
top down processing
number of cycles, completed by a sound wave in 1 second. it determines pitch, measured in Hertz
determines loudness and measured in decibel
determines distinctive qualities of a sound
theory that each individual pitch a person hears is determined by the spot that vibrates the most
place theory
theory that hair cells vibrate the same number of times. pitch is determined by how many times hair cells move back and forth at 1000 Hz, hair cells can't vibrate with pitch greater than 1000 Hz
frequency theory
2, one-square inch patches of tissue. Contains 10 million olfactory neurons, which are the receptor smells for smell.
olfactory epithelium
2 brain structures the size of matchsticks where smell sensations first register in the brain.
olfactory bulbs
basic tastes
sweet, sour, salty, bitter, umami
pathway of smell
olfactory epithelium olfactory bulbs thalamus orbitofrontal cortex
the orbitofrontal cortex controls what senses?
taste and smell
theory that an area in the spinal cord acts as a gate and either blocks pain messages or transmits them to the brain
gate control theory
sense that detects movement and provides info about the body's orientation in space
vestibular sense
3 fluid-filled tubular canals in the ear(inner) that sense the rotation of the head. movement is triggers hair cells and senses balance.
semi-circular canals.
