Check answer

Question 6

Multiple Choice

The gray intersections in the Hermann Grid _____ .

Choose correct answer/s

are physically present

are explained by dark adaptation

support the claim that "perception is not the same as the physical stimulus"

support the claim that what is learned in animals is not applicable to humans

Question 7

Multiple Choice

In Hermann's grid, a possible explanation for why gray areas appear at the intersections is because _____ .

Choose correct answer/s

the amount of inhibition right at the intersections is twice as great as the inhibition between each square

the amount of inhibition right at the intersections is much less than the inhibition between each square

the superior colliculus responds maximally as you move your eye from intersection to intersection

moving the eye creates a blur at all the intersections
