5). Consider the general properties of color vision.
A) All vertebrate species have some form of color vision.
B) In daylight, color vision usefully adds a lot of detail to the view of a scene.
C) Color vision is based on a combination of rod and cone responses.
D) Human color vision is based on responses of 4 types of cone.
6). “Trichromacy” means that normal, adult color vision has three independent dimensions; these could be:
A) Sensations of hue, brightness, and saturation.
B) Spectral sensitivities of L, M, S cones.
C) Intensities of three primary lights in an additive color mix to match appearance of a specific stimulus.
D) All of the above.
13). Shapes of objects in a visual image can be specified as an assembly of cylinders of various sizes, or analysis of intersections of contours, etc. David Marr proposed a more general computational theory to identify such objects; assuming that the unseen back of an object is the same as the visible front:
A) the visual image of an object can be described as a silhouette.
B) a silhouette can be summarized as a “generalized cone.”
C) a “generalized cone” is an object whose cross-section has the same shape along its length.
D) All the above are correct.
32). To see the inside of a trapezoidal room (Ames-Ittelson room) as a normal room
A) it must be viewed binocularly.
B) binocular convergence is necessary.
C) it must be viewed monocularly through a small peephole.
D) it must be viewed from above.
37). The neuronal components of stereopsis may be
A) neurons in area V1 that respond only to very narrow ranges of disparity.
B) many neurons in area V2 respond equally strongly to diplopic images at a range of distances beyond Panum’s area and closer to the observer.
C) the complet absence of neurons responding to diplopic images.
D) A and B, above, are both correct.
39). Animal species typically have color vision
A) that does not include ultraviolet radiation, provided they have relatively long life-spans.
B) that includes ultraviolet radiation, provided they have short life-spans.
C) including ultraviolet light, provided they are not honey bees.
D) unless they have colored oil-droplets in their cones.
42). To derive the details of images of many familiar objects easily, they must
A) always be examined in different orientations.
B) always be examined in orientations other than the ones in which they typically appear.
C) be presented in the orientations in which we typically see them.
D) have all the details of the object in the same orientation.
48). Richard’s 3-pool hypothesis about the types of neurons involved in stereopsis postulates
A) that one type responds only to crossed (convergent) disparities.
B) that one type responds only to diplopic images of objects near the horizon.
C) that none respond to both crossed and uncrossed disparities.
D) that depth perception cannot be specified by responses of single neurons.
