To see an object best in normal to bright levels of light, you should look _____.
to the side, so the object is focused on the periphery of the retina where more rods are located
directly at the object, so it is focused on the fovea where more cones are located
to the side, so the object is focused on the periphery of the retina where more cones are located
directly at the object, so it is focused on the fovea where more rods are located
Cones differ in the extent to which they respond to different wavelengths of light because the cones _____.
are located at different locations on the retina
are different colors
contain different photopigments
have different sizes
The trichromatic theory of color vision proposes that we have three types of _____.
cones and that each type is specialized for two complementary colors
cells that perceive wavelengths of light and that they are located in the post-receptor level of processing (along the visual pathways from the bipolar cells to the brain)
cones specialized for perceiving wavelengths of light corresponding to red, green, and yellow
cones specialized for perceiving wavelengths of light corresponding to blue, green, and red
The trichromatic theory of color vision proposes that the perception of color _____.
occurs when cones respond selectively to certain ranges of light wavelengths
is much like mixing different colors of paint to achieve a single color that is new
results from cones responding in a stimulate/inhibit fashion to specific pairs of colors
is the process of cones responding selectively to certain ranges of light wavelengths but in a stimulate/inhibit fashion to pairs of colors
