absolute threshold the lowest level of a stimulus – light, sound, touch, etc. – that an organism could detect.
difference threshold a point or way in which people or things are not the same.
signal detection theory a means to measure the ability to differentiate between information-bearing patterns and random patterns that distract from the information

receptor cells proteins either inside a cell or on its surface which receive a signal
rods a type of photoreceptor cell in the retina. They are sensitive to light levels and help give us good vision in low light. They are concentrated in the outer areas of the retina and give us peripheral vision.
cones They give us our color vision
optic nerves comprised of millions of nerve fibers that send visual messages to your brain to help you see
blind spot the point of entry of the optic nerve on the retina, insensitive to light.
trichromatic theory human eyes only perceive three colors of light: red, blue, and green.
opponent-process theory the human visual system interprets information about color by processing signals from photoreceptor cells in an antagonistic manner.
pitch the perception of the frequency of sound waves
cochlea the spiral cavity of the inner ear containing the organ of Corti, which produces nerve impulses in response to sound vibrations.
