The relationship between illuminance and brightness

Question 1 of 6

1

What is simultaneous brightness contrast?

Select one of the following:

  • When two areas of the same brightness appear to have different brightness' dependent on their backgrounds

  • When two areas of different brightness appear to have the same brightness dependent on their background

  • When two areas of the same brightness appear to be the same brightness dependent on their backgrounds

  • When two areas of different brightness appear to have different brightness' dependent on their backgrounds

Explanation

Question 2 of 6

1

What is the mechanism that controlls simultaneous brightness contract called?

Select one of the following:

  • Lateral inhibition

  • Simultaneous inhibition

  • Lateral facilitation

  • Simultaneous facilitation

Explanation

Question 3 of 6

1

What is an on center, off surround ganglion receptive field?

Select one of the following:

  • Increased brightness creates a stronger response when this is within the on center, but creates a stronger inhibitory response when within the off surround

  • Decreased brightness creates a stronger response when this is within the on center, but creates a stronger inhibitory response when within the off surround

  • Decreased brightness creates a stronger inhibitory response when this is within the on center, but creates a stronger response when within the off surround

  • Increased brightness creates a stronger inhibitory response when this is within the on center, but creates a stronger response when within the off surround

Explanation

Question 4 of 6

1

How are match bands affected by lateral inhibition?

Select one of the following:

  • A uniform grey going from dark to light appears to have brighter bars separating it

  • A set of grey bars going from light to dark, separated by lighter bars appear to be a uniform grey

  • When looking at the lighter bands there appears to be a grey dot in the intersection

  • The contrast within a uniform grey appears unchanged

Explanation

Question 5 of 6

1

(a) What is the Hermann or Hering grid illusion? and how is this affected by lateral inhibition?

Select one of the following:

  • Black squares spaced apart on a white background, grey dots will be perceived in the intersections

  • White squares spaced apart on a black background, grey dots will be perceived in the intersections

  • Black squares spaced apart on a white background, grey dots will be perceived in the square centers

  • White squares spaced apart on a black background, grey dots will be perceived in the square centers

Explanation

Question 6 of 6

1

Why does lateral inhibition happen, function?

Select one of the following:

  • Perception only cares about the contrast (edges) and properties that help determine edges, not the retinal image

  • Perception does not care about the contrast (edges) and properties that help determine edges, only the retinal image

  • Perception cares about both the contrast (edges) and properties that help determine edges, and the retinal image

  • Perception only cares about neither the contrast (edges) and properties that help determine edges, or the retinal image
