Ch 6

2. The psychological correlates of wavelength and intensity are________, respectively.

  • color and brightness
  • brightness and hue
  • shape and color
  • brightness and shape
Ch 6

3. The adjustment of pupil size in response to changes in illumination represents a compromise between________.

  • size and position
  • accommodation and disparity
  • sensitivity and acuity
  • color and shape
Ch 6

4. When rhodopsin is moved from the dark to intense light,_________.

  • it absorbs light in the same range of wavelengths as the scotopic spectral sensitivity curve
  • it becomes bleached
  • it becomes an intense red color
  • it gains light-absorbing properties
Ch 6

5. The photopic visual system is characterized by_______.

  • a high degree of convergence onto biopolar cells
  • maximal sensitivity to light in the range of 560 nm
  • high visual acuity
  • high sensitivity
Ch 6

6. Off-center cells include __________.

  • rods and cones
  • retinal ganglion cells
  • simple cortical cells
  • complex cortical cells
Ch 6

7. Hubel and Wiesel found that several neurons encountered along a(n) _______ electrode tract in the primary visual cortex had receptive fields in the same general area of the visual field and preferred straight line stimuli in the same orientation.

  • oblique
  • straight
  • vertical
  • horizontal
Ch 6

8. The ventral visual stream has been referred to as the _______ pathway, which flows from the primary visual cortex to the ventral prestriate cortex and finally to the ________ cortex.

  • what ; inferotemporal
  • where ; posterior parietal
  • what ; posterior parietal
  • where ; inferotemporal
Ch 6

9. Because of the phenomenon of color constancy, the color of an object_______.

  • varies with changes in illumination
  • does not vary with changes in illumination
  • will vary depending on whether the photopic or the scotopic visual system is active
  • does not vary regardless of whether the photopic or the scotopic visual system is active
Ch 6

10. The retinal ganglion cells _______.

  • are responsible for scotopic vision only
  • are responsible for lateral communication across the retina
  • transduce light energy in the range of 560 nm
  • are the most superficial layer of cells in the retina
Ch 6

11. The retina-geniculate-striate system________.

  • contains neurons that are generally monocular
  • is retinotopically organized
  • contains simple cells at all levels
  • conveys information from each eye to primary visual cortex in both hemispheres
Ch 6

12. cones are to rods as________.

  • color vision is to viewing shades of gray
  • photopic vision is to scotopic vision
  • high sensitivity is to high acuity
  • high convergence is to low convergence
Ch 6

13. The M pathway for visual information is ________.

  • responsible for conveying information about moving objects
  • comprised of magnocellular neurons in the LGN and the retinal ganglion cells that project to them
  • largely responsible for conveying information from rod photoreceptors
  • found in the upper four layers of the LGN
Ch 7

14. Prosopagnosia is ______.

  • an inability to recognize faces
  • may be a general inability to recognize individual members of a complex class of visual stimuli
  • Due to damage to striate cortex
  • Due to damage to the posterior parietal cortex

Ch 5

19. The size and shape of a radio-frequency lesion is determined by _______.

  • The duration and intensity of current
  • The size of the subject
  • The configuration of the electrode
  • The location of the electrode
Ch 5
