In humans, evolution may have favored two eyes facing forward because it statistically increases the chance of detecting a stimulus. The combination of signals from the two eyes that enhances performance on many tasks is called
A. stereoacuity
B. binocular summation
C. binocular vision
D. stereo summation

The combination of signals from two eyes that enhances visual performance is known as binocular summation . This process leads to improved depth perception and spatial awareness, which are crucial for survival. In contrast, stereoacuity specifically relates to the perception of depth through the differences in images from each eye. ;
