Chapter 6 Review
PSYCH 335


1. Adjusting the configuration of the lens to bring images into sharp focus on the retina

is accomplished by the ciliary muscles
increases acuity
is called accommodation
all of the above


2. Which of the following retinal cells have axons?

rods
cones
retinal ganglion cells
bipolar cells


3. If a woman's optic chiasm were cut down the midline, she would be

totally blind in her contralateral visual field
totally blind in her fovea
blind in her two temporal hemiretinas
blind in her two nasal hemiretinas


4. An effective way of activating on-center cells of the retina-geniculate-striate system is to illuminate the entire

visual field with intense light
receptive field with intense light
"on" area with intense light
retina with intense light


5. The physical dimension of light wavelength is most associated with the perception of

hue
brightness
saturation
saturation


6. Color constancy suggests that the perception of color

is mediated by complex cortical cel
is mediated by component retinal cells
is mediated by three different kinds of cones
depends on the analysis of comparisons between the wavelengths of light received from different areas of the visual field


7. Which of the following is true of transduction of light into nerve potentials?

the retinal photoreceptors lie at the front of retina, closest to the lens
light hyperpolarizes the retinal photoreceptors
glutamate is released by photoreceptors in response to light
light depolarizes the retinal photoreceptors


8. The portion of the visual field to which a neuron changes its firing rate is considered to be

sensitive to more than one sensory modality
a receptive field
carried out by the magnocellular visual system
carried out by the parvocellular visual system


9. Which of the following is NOT a function of the magnocellular visual system?

brightness analysis
depth analysis
analysis of movement
analysis of color


10. Visual agnosia involves

an inability to recognize a stimulus via a sensory modality
lesions of the striate cortex
deficient visual acuity
failure to integrate bilateral visual input
