Sensations

TermDefinition
sensation process by which our sensory receptors and nervous system recieve and represent stimulus energies from our environment
perception the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events
bottom-up processing analysis that begins with the sensory receptors and works up to the brain's integration of sensory information
top-down processing information processing guided by higher level mental processes
absolute threshold the minimum stimulation required to detect a particular stimulus 50% of the time
difference threshold the minimum difference between two stimuli required for detection
jnd just noticeable differences
Weber's law to be percieved as different, two stimuli must differ by a constant percentage
signal-detection theory predicts how and when we detect the presence of a faint stimulus amid background stimulation
subliminal below one's absolute threshold for conscious awareness
priming activation, of unconsciously, of certain associations, thus predisposing one's perception, memory, or response
sensory adaptation diminished sensitivity as a consequence of constant stimulation
transduction conversion of one form of energy into another
wavelength distance from peaks of waves
hue dimension of color determined by wavelength
fast wavelength color blue
slow wavelength color red
intensity amount of energy in a wave determined by amplitude
cornea membrane that protects the eye
iris ring of muscle tissue that forms the colored portion of the eye and controls the size of the pupil opening
pupil adjustable opening in the center of the eye where light enters
lens behind the pupil that changes shape to help focus the images on the retina
accomidation process where the eye's lens changes shape to focus on near of far objects
retina light-sensitive inner surface of the eye
fovea central focal point in the retina, where the cones cluster
blind spot where the optic nerve leaves the eye and has no receptor cells
optic nerve nerve that carries neural impulses from the eye to the brain
rods white, black, gray and activated by dim light
cones bright light and color
feature detectors nerve cells in the brain that respond to specific features of the simulus
parallel processing processing of many aspects of a problem simultaneously
Young-helmholtz trichromatic theory the retina contains three different color receptors (red, green, blue) that can produce the perception of any color
opponent process theory opposing retinal processes (red and green, blue and yellow, black and white) that enable color vision
acuity sharpness of vision
color constancy the color of an object remains the same under different illuminations
audition sense or act of hearing
pitch tone's experienced highness or lowness
eardrum tight membrane that vibrates when struck by sound waves
middle ear hammer, anvil, and stirrup that concentrate the vibrations
outer eat auditory canal and eardrum
oval window entrance to the cochlea
inner ear cochlea, semicircular canals, and vestibular sacs
cochlea coiled, bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses
basilar membrane membrane on the cochlea with millions of hairs that vibrate fluid to create neural impulses
auditory nerve sends the auditory message to the brain via the thalamus
place theory links pitch with the place where the cochlea's membrane is stimulated
frequency theory the rate of nerve impulses traveling up the auditory nerve matches the frequency of a tone
conduction hearing loss caused by damage to the mechanical system that conducts sound waves to the cochlea (eardrum or three bones)
sensorineural hearing loss causes by damage to the cochlea's receptor cells or to the auditory nerve
cochlea implant device for converting sound into electrical signals and stimulating the auditory nerve through electrodes threaded into the cochlea
types of touch (4) pressure, warmth, cold, pain
kinesthesis senses the position and movement of individual body parts
vestibular sense sens of body movement and position and includes balance
noiceptors activated by signals of damage
gate-control theory spinal cord contains gates that block pain signals or allows them to pass to the brain
phantom limb sensation feeling limb after amputated
rubber hand illusion think you feel the rubber hand
types of taste (5) sweet, salty, sour, bitter, umammi
word for taste gustation
sensory interaction one sense may influence another
word for smell olfaction
