Question
Answer
Sensation   show
🗑
show Organizing and interpreting sensory information  
🗑
Bottom-up Processing   show
🗑
show construction of perceptions based on knowledge, experience, or expectations  
🗑
Psychophysics   show
🗑
Absolute Threshold   show
🗑
Signal Detection Theory   show
🗑
subliminal   show
🗑
show the activation of certain associations that predispose someone to give a certain response, recall a specific memory or perceive something in certain way, that usually occurs unconsciously.  
🗑
show the minimum difference between stimuli required to identify the difference fifty percent of the time, also called the just noticeable difference.  
🗑
show the principle that two stimuli must differ by a constant percentage, rather than a constant amount, to be perceived as different.  
🗑
sensory adaptation   show
🗑
show the conversion of one form of energy to another  
🗑
wavelength   show
🗑
hue   show
🗑
intensity   show
🗑
show the opening in the center of the eye through which light enters  
🗑
show a ring of muscle tissue that surrounds the pupil and controls its size  
🗑
show a transparent structure behind the pupil that changes shape to focus images on the retina  
🗑
show when the lens changes shape to focus objects at a specific distance on the retina  
🗑
show the light-sensitive inner surface of the eye that contains the receptor rods and cones as well as layers of neurons that begin to process visual information  
🗑
acuity   show
🗑
show a condition in which near objects can be more easily seen than distant objects because distant objects focus in front of the retina  
🗑
show a condition in which distant objects can be more easily seen that near ones because the images of near objects are projected behind the retina  
🗑
rods   show
🗑
cones   show
🗑
show the pathway that carries neural impulses from the retina to the brain.  
🗑
blind spot   show
🗑
fovea   show
🗑
show nerve cells in the brain that respond to specific aspects of a stimulus, such as shape, angle, or movement  
🗑
show the brain's natural mode of information processing, in which several aspects of a stimulus; such as shape, color, and motion, are processed at once.  
🗑
show the theory that the retina contains three different color receptors - red, green, and blue - which can produce any color when stimulated in combination  
🗑
show the theory that opposing retinal processes, such as red-green or yellow-blue, enable the perception of color.  
🗑
show perceiving familiar objects as having consistent color despite changing illumination  
🗑
audition   show
🗑
show the number of complete wavelengths that pass a point in a given time  
🗑
show the highness or lowness of a tone, dependent on frequency  
🗑
middle ear   show
🗑
show a coiled, bony, and fluid-filled tube in the inner ear through which sound waves trigger neural impulses  
🗑
show the part of the ear that contains the cochlea, semicircular canals, and vestibular sacs  
🗑
show the theory that the place where the cochlea's membrane is stimulated determines the the pitch of a tone  
🗑
show the theory that the rate of neural impulses traveling up the auditory nerve matches the frequency of a tone, determining its pitch  
🗑
show hearing loss caused by damage to mechanical systems in the ear  
🗑
show hearing loss caused by damage to the cochlea's receptor cells or the auditory nerves  
🗑
show a device that converts sounds into electrical impulses to stimulate the auditory nerve through electrodes threaded into the cochlea  
🗑
show the theory that pain is controlled through a neurological gate in the spinal cord that can allow pain signals or allow them to pass through to the brain.  
🗑
sensory interaction   show
🗑
kinesthesis   show
🗑
vestibular sense   show
🗑
afterimage effect   show
🗑
show (ear canal) a tube running from the outer ear to the middle ear.  
🗑
show a thin membrane that separates the external ear from the middle ear in humans and other tetrapods  
🗑
amplitude   show
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
