Chapter 6 Flashcards
Depth of focus is normally greater
when the pupils are constricted
The phenomenon of color constancy makes the point that
the perceived color of an object is not solely determined by the wavelengths of light that it reflects
When the enters the eye, the photons pass through the layers of the retina in what sequence?
ganglion, amacrine, bipolar, horizontal, receptors
The existence of complementary afterimages supports
the opponent-process theory
Simple cells of the primary visual cortex
have receptive fields with static “on” and “off” areas that are separated by a straight edge
What can be found at the blind spot?
the axons of the retinal ganglion cells
A spectral sensitivity curve shows that the brightness of a light depends on
both the wavelength and the intensity of the light wave
Mammals without cones tend to
be nocturnal
With respect to vision, wavelength is to intensity as
color is to brightness
In the lateral geniculate nucleus, parvocellular is to magnocellular as
small is to big
Most researchers support the “where” vs. “what” theory about the dorsal and ventral streams. An alternative theory claims that the respective functions of the dorsal and ventral streams are
“control of behavior” vs. “conscious perception”
The neural basis of contrast enhancement depends on a type in interaction among neurons that is called
lateral inhibition
