Even if you only have one eye, you would still be able to drive a car or land an airplane. The ability to still engage in tasks that require depth perception shows that
a.
most depth cues are monocular in nature.
b.
depth perception in a one-eyed individual is limited, not absent.
c.
stereoscopic vision is only slightly better for judging depth than is accommodation.
d.
pictorial depth cues are even more important than other depth cues.

b.

depth perception in a one-eyed individual is limited, not absent.

Explanation:

Information about depth that relies on just one eye, includes relative size , light and shadow, interposition, relative motion, and atmospheric perspective. Depth perception means perception of distances from object from each other or from observer.

As in one eyed individuals, depth perception is limited, not entirely absent, hence, they would still be able to drive a car or land an airplane.

Hence the correct option is b.  depth perception in a one-eyed individual is limited, not absent.

this null effect is caused by a weak manipulation and ineffective internal validity. in a scientific study, as the one dr. morimoto is trying to perfom, internal validity refers to the confidence placed in the cause-effect relationship and to how well an experiment is done and able to eliminate confounding variables.
