Term Definition
glucagon a hormone that tends to increase levels of blood sugar
adrenal gland structure that creates adrenaline
adrenal gland structure that creates adrenaline
Young-Helmholtz theory states that we process color vision using color-specific cones
frequency theory accounts for how we perceive low-pitched sounds
place theory accounts for how we perceive high-pitched sounds
frequency theory states that certain frequencies cause the entire basilar membrane to vibrate
place theory states that certain frequencies stimulate hair cells only in certain areas on the basilar membrane
optic chiasm here left visual field and right visual field are sorted out to be sent to the appropriate hemisphere of the brain
ganglion cell its axon forms part of the optic nerve
bipolar cell receives information from rods and cones and passes it on to ganglion cells
blind spot point where the optic nerve leaves the retina
trichromatic theory states that color vision is possible because we have RGB cones
transduction the process of changing one form energy to another
education means to "lead out of"; uses same root as transduction
signal detection theory explains why thresholds change for different people and in different situations
absolute threshold the intensity level of a stimulus at which one can detect the stimulus 50% of the time
difference threshold minimum difference between the intensity levels of two stimuli that we can detect 50% of the time
Weber's Law the difference threshold of two pairs of similar stimuli will be different in magnitude but will be equal in percentage
an application of Weber's Law you can tell the defference between a 4 pound barbell and a 6 pound barbell, but not between 50 and 52 pounders
photoreceptor a neuron that is sensitive to light
adaptation the reason we don't feel the weight of earrings all the time
rods enable us to see in very low light
cones come in red, green and blue models
iris the blue part of blue eyes
pupil it is a place, but not a thing
lens focuses light onto the retina
opponent process theory explains why some people are red-green color blind
retina contains the rods and cones
tympanic membrane also called an eardrum
visual cortex located in the occipital lobe
pinna the outside part of the ear
ossicles little bones in the middle ear
stirrup connects the anvil to the oval window
anvil connects the hammer to the stirrup
top-down refers to processing in which our experience and expectations influence our perceptions
bottom-up refers to visual processing in which experience does not influence perception
sensation the process of receiving information from the environment
perception selecting and interpreting information from the environment
hue wavelength has to do with
brightness intensity has to do with
saturation purity has to do with
habituation decline in sensory sensitivity as stimulation is repeated
selective attention only attend to singal thing
light as it enters eye light-->retina-->bipolar-->ganglion-->optic nerve-->visual crossover-->optic chiasm-->thalamus
cochlea fluid-filled tube in ear through which sound waves trigger nerve impulses
parallel processing doing several things at once
accomodation lens changes shape to focus objects on retina
optic nerve carries neural impulses from eye to brain
feature detector neurons that receive information and respond to a scene's specific features-edges, lines, movements, angles
frequency number of complete wavelengths that pass a point at a given time
highness or lowness pitch
conduction hearing loss caused by damage to the mechanical system
sensorineural hearing loss caused by damage to receptors or auditory nerves
motion parallax as we move, objects that appear to be stable seem to move
texture gradient change from coarse distinct this to fine indistinct this signals increasing distance
linear perspective parallel lines appear to converge with distance
vestibular sense feeling of balance, moniters position of head
depth perception ability to see objects in 3 dimensions, allows us to judge distance
figure-ground organization of objects that stand out of their surroundings
grouping tendency to organize stimuli into coherent groups
gestalt whole
selective attention attending to one stimulus as in the cocktail party effect
inattentional blindness failing to see visible objects when our attention is directed elsewhere
selected attention the focusing of conscience awareness on a particular stimulus
sweet, sour, salty, bitter, msg the 5 tastes
kinethesis the sense of our body parts' position and movement

stellanaulo : Changed convergence → structure that creates adrenaline to adrenal gland → structure that creates adrenaline
stellanaulo : Changed vestibular sense → feeling of balance, moniters position of movement to vestibular sense → feeling of balance, moniters position of head
stellanaulo : Changed sweet, sour, salty, bitter → the 4 basic tastes to sweet, sour, salty, bitter, msg → the 5 tastes
stellanaulo : Changed pitch → highness or lowness to highness or lowness → pitch
stellanaulo : Changed intensity has to do with → brightness to brightness → intensity has to do with
stellanaulo : Changed purity has to do with → saturation to saturation → purity has to do with
stellanaulo : Changed wavelength has to do with → hue to hue → wavelength has to do with
