Psych 111 Exam 2 Study Guide.
Sensation - answer✔the reception of environmental information through your sensory organs
perception - answer✔process where meaning is imposed on sensations
reception - answer✔stimulation of senses
transduction - answer✔transform sensory stimulation to neural impulses
transmission - answer✔sensory information sent to the brain
sensory adaptation - answer✔diminished sensitivity as a consequence of constant stimulation
absolute threshold - answer✔minimum stimulus needed to detect some kind of sense half the time
difference threshold - answer✔minimum difference you can detect between 2 stimuli half the time
weber's law - answer✔the size of the just noticeable difference depends on the strength of the physical
objects, all senses differ, more intense sensation, smaller noticeable differences
vision - answer✔processing information in visible light, different waves of electromagenetic radiation
can be picked up by eye
cornea - answer✔the transparent outer covering of the eye
pupil - answer✔opening in the center of the iris
iris - answer✔Colored part of the eye, ring of muscles, controls diameter of pupil
lens - answer✔transparent layer, alters shape to focus on near or far objects, called accomodation
retina - answer✔neural tissue in back of eye, where transduction happens
rods - answer✔sensitive to faint light, dim, more rods than cones, basic sensory info
cones - answer✔sensitive to color and detail, clustered in fovea/center of retina
blind spot - answer✔optic disc where nerve cells leave retina, filled in by brain or eye movement
blindsight - answer✔damage to visual cortex, eyeballs function normally but person feels completely
blind

hue - answer✔wavelength, long wave red light, short wave blue light
saturation - answer✔purity of waves, stronger colors
brightness - answer✔height/amplitude of waves
trichromatic theory of color vision - answer✔all colors are combinations of red blue and green color
receptor cones that react to different wavelengths
opponent process theory of color vision - answer✔photoreceptors paired together and activation of one
member of pair inhibits the other, blue v yellow, red v green, black v white
frequency of sound - answer✔corresponds to our perception of pitch
amplitude of sound - answer✔correspons to our perception of loudness
outer ear - answer✔collects sound waves, consists of pinna, ear canal, and eardrum
middle ear - answer✔amplifies sound waves, has 3 small hones the hammer anvil and stirrup, move at
same frequency as eardrum
inner ear - answer✔where sound is transduced, cochlea, semicircular canals related to balance, fluid in
cochlea swishes over tiny hair cells that send action potential down auditory nerve
conduction hearing loss - answer✔middle ear isn't conducting sound well to the cochlea
sensorineural hearing loss - answer✔receptor cells arent sending messages, caused by damage to hair
cells in cochlea
olfaction - answer✔smell, chemical sense, processed in olfactory bulb, bind to receptors on olfactory
nerve
taste - answer✔chemical sense, flavors binding to tongue and trigger action potential, sweet, sour,
umami, bitter, salty
touch - answer✔every touch sensation combination of pressure, warmth, cold, and pain
pain - answer✔an unpleasant sensory and emotional experience associated with actual or potential
tissue damage
nociceptors - answer✔small sensory fibers in skin, muscles, and internal organs
gate control theory - answer✔spinal cord can act as a gate for pain signals to brain, open to intensify
pain, closed to reduce pain
proprioception - answer✔body movement and position
