Processes
this process is when you detect stimuli
sensation
this is the small, adjustable opening in the iris that gets bigger to let it more light.
pupil
name the 5 senses
taste, touch, smell, sight, sound
the part of the ear the sounds waves hit after traveling through the ear canal
ear drum
these drugs distort your perceptions and make you see/hear things without actual stimuli
hallucinogens
this processes is when you organize and interpret sensory input
perception
these two types of receptors are located on the retina. on top of your board, name the receptor that sees black and white, peripheral movement, and works in low light. on the bottom, name the receptor that sees color
rods, cones
small, fluid-filled part of the inner ear that converts vibrations into electrical signals
cochlea
lobe of the brain that processes sound
temporal lobe
these drugs activate the CNS/motivation centers and reduce your inhibitions
for a bonus 50 pts: give an example
stimulant
nicotine, caffeine, amphetamines, ritalin
this process is when your preexisting knowledge or expectations guides how you process info and construct perceptions
top-down processing
this is the transparent, curved structure behind the pupil that changes shape in order to focus incoming light into an image
lens
This is a theory for how color vision works: the three types of cones are stimulated by different wavelengths of light. Each color is a combination of different cones activating.
trichromatic theory
fluid-filled spiral structure in the ear that transmits sounds further into the brain
cochlea
these types of drugs reduce CNS activity and induce sleep
for an extra 50 pts, give an example
depressants
valium, xanax, ambien
this process is when you first detect sensation and your brain then processes the information to construct a perception
bottom-up processing
this is the transparent curved layer that covers the whole front of the eye
cornea
name the part of the ear that these three bones are part of: hammer, anvil, stirrup
middle ear
structure in the brain that processes speech
wernicke's area
These hormones are natural pain relievers and are release when you exercise
endorphins
this is the weakest level of a stimulus that can be detected correctly at least half the time
absolute threshold
these are clues about distance that require both eyes - they use retinal disparity (the difference between the image for eay eye)
binocular cues
this theory states that our absolute threshold can change depending on fatigue, attention, emotions, etc.
signal detection theory
besides the ear canal, ear drum, and cochlea, name one other part of the ear
bones of the inner ear (stirrup, anvil, hammer), semi-circular canals
describe the process of neurotransmission.
a neurotransmitter is released from the axon across the synapic gap and picked up by the dendrite of the next neuron.
