Nagata et al. (2012) were interested in the neural mechanisms Adanson's jumping spiders use for depth perception. They found that the spiders: |
| |
A) |
use color information but not depth perception. |
| |
B) |
see in depth by coordinating information from across their many eyes. |
| |
C) |
compare images on different levels of their retinae to determine depth. |
| |
D) |
use the comparison of their vision and their jump to infer distance. |

A) |
movement-based cues. |
| |
B) |
pictorial cues. |
| |
C) |
stereo cues. |
| |
D) |
monocular depth cues. |

Heinrich knows that a vase is much smaller than a statue. However, because the vase appears larger, Heinrich knows it must be closer. Heinrich is using: |
| |
A) |
relative height. |
| |
B) |
relative distance. |
| |
C) |
linear perspective. |
| |
D) |
familiar size. |

Francois is a passenger in a car moving at 65 miles per hour down the highway. When Francois looks out the windows, nearby objects will appear to rush by him in the opposite direction, but objects farther way appear to move more slowly relative to the car. Which depth cue is this associated with? |
| |
A) |
Binocular disparity. |
| |
B) |
Motion parallax. |
| |
C) |
Linear perspective. |
| |
D) |
Optic flow. |

The sense of depth we perceive from the visual system's processing of the comparison of the two different images from each retina is known as: |
| |
A) |
stereopsis. |
| |
B) |
optic comparisons. |
| |
C) |
retinal parallax. |
| |
D) |
binocular rivalry. |

The region in space where the two images from an object fall on corresponding locations on the two retinae is known as the: |
| |
A) |
corresponding point. |
| |
B) |
vergence point. |
| |
C) |
horopter. |
| |
D) |
parallax. |

In a 3D movie, if a filmmaker wants an image to come out of the screen toward the viewer, the filmmaker will create: |
| |
A) |
stereoscopic disparity. |
| |
B) |
zero disparity. |
| |
C) |
uncrossed disparity. |
| |
D) |
crossed disparity. |

If object recognition is necessary for matching correspondence, then random-dot stereograms will not result in a 3D perception. However, if correspondence matching occurs before object recognition, then it should be possible for people to extract binocular depth cues from random-dot stereograms. What has research found? |
| |
A) |
Random-dot stereograms can be detected only while in motion. |
| |
B) |
People can extract binocular depth cues from random-dot stereogram. |
| |
C) |
People cannot extract binocular depth cues from random-dot stereogram. |
| |
D) |
Random-dot stereograms cannot produce 3D perception in the absence of monocular depth cues. |

Size constancy is: |
| |
A) |
the invariance of visual angle as a function of disparity when an object gets closer or moves father away. |
| |
B) |
the principle that predicts where the horopter will be on each retina of a person's eyes. |
| |
C) |
an illusion in which relative size is distorted, despite the fact that the size of the object has not changed. |
| |
D) |
the perception of an object as having a fixed size, despite the change in the size of the visual angle that accompanies changes in distance. |

Hofeldt and Hoefle (1993) compared professional baseball players in the highest professional league (the major leagues) with professional baseball players who had not made the highest professional league (the minor leagues). They found that: |
| |
A) |
the better baseball players were more likely to misperceive the Ponzo illusion. |
| |
B) |
stereopsis did not predict baseball performance in either league. |
| |
C) |
the major league players did not have a dominant eye but the minor league players did. |
| |
D) |
the major league players were more accurate at a stereoscopic task than the minor league players. |

visual angle. |
| |
C) |
disparity. |
| |
D) |
correspondence ratio. |

B) |
the same image printed in red to the left eye and green to the right eye. |
| |
C) |
anaglyph images to both eyes. |
| |
D) |
the same image printed in color to the left eye and black and white to the right eye. |
