HF 300 Exam 2 Questions with Correct Answers Latest Update 2025/2026
To become fully dark adapted, the normal human eye requires: - Answers approximately 30
minutes in a dark environment
The monocular depth cue that is provided by signals from the muscles used to bulge or flatten
the lens when focusing on targets at various distances is called - Answers accommodation
Binocular disparity refers to the fact that: - Answers two eyes receive slightly different images
The light-absorbing pigment of rods is: - Answers rhodopsin
The appearance of one object partially concealing another object refers to the spatial/depth cue
of: - Answers interposition
Why did pirates wear patches? - Answers to maintain dark adaptation in one eye
Objects that lie at different distances from the eye tend to move across the retina at different
rates as the observer moves. This provides a vital cue to depth and distance called: - Answers
motion parallax
The visual cliff research in babies had multiple research designs that led to their ultimate
conclusion that depth perception develops over time based on experience. In two research
designs, they recruited babies who had experience crawling and new crawlers (recently started
crawling) to participate. In the other, all babies had no experience crawling (pre-crawlers), but
they attempted to manipulate this experience by teaching the babies to use a motor controlled
car. The first two are an example of a(n) research design while the last is an example of a(n)
research design. - Answers quasi-experimental, and experimental
If I wanted to ensure people opening a fridge in the dark could both see the fridge contents and
still see very well after closing the fridge, how might I modify the light of the fridge? - Answers
Have it emit only ~650 nm (red) light
Rod receptors undergo major physical changes when exposed to light that take approximately -
Answers 25-40 minutes to return to normal
Cone cells can adapt to low(er) light faster - Answers within 6 minutes but only to the extentthey
are sensitive.
stereoscopic vision - Answers the ability to determine an object's depth based on that object's
projections to each eye
Motion Parallax - Answers the perception of motion of objects in which close objects appear to
move more quickly than objects that are farther away
Anthropometric - Answers measurements of the body and body parts
