Question

The connections between neurons in the retina, specifically the connections referred to as “lateral inhibition,” help us see which of the following better?
AContrast
BFaces
CColors

Improving the contrast of an image (making the dark regions darker and the light regions lighter) helps us to identify:

AThe edges of objects
BThe center of objects
CThe color of an object

What assumption does our visual system make in order to see curved surfaces (domes, holes)?

ALight comes from above
BCurved surfaces are always evenly lit
CCurved surfaces are always easy to see, no assumptions are made

Which part of the face does our brain pay the most attention to?

AEyes and mouth
BEyes and ears
CEyes and chin

If all these assumptions sometimes lead to mistakes, for example in these optical illusions, why do we make them?

AIt helps us see things faster
BIt helps us see things correctly
CIt helps us pay attention to what's important
DAll of the above
