2. which of the following statements regarding depth perception is true?
a. texture gradient is a monocular cue
b.experience teaches us to perceive relative size as an indicator of the color of an object
c.motion parallax is detected because we perceive binocular disparity
d.the change in position of an object relative to the retina is a binocular cue
ans c
It's not C
The correct statement regarding depth perception is option c: "Motion parallax is detected because we perceive binocular disparity."
To determine which statement is true, let's examine each option and understand the concepts involved:
a. Texture gradient is a monocular cue: Texture gradient is a depth cue based on the perception of the change in the size and density of texture as it recedes into the distance. This statement is accurate.
b. Experience teaches us to perceive relative size as an indicator of the color of an object: This statement is unrelated to depth perception and is therefore incorrect.
c. Motion parallax is detected because we perceive binocular disparity: Motion parallax is a monocular cue that helps us perceive depth by noticing the relative motion of objects as we move. Binocular disparity refers to the slight differences in the images received by each eye. So, this statement is incorrect.
d. The change in position of an object relative to the retina is a binocular cue: This statement refers to motion parallax, which is a monocular cue, not a binocular cue. Therefore, this statement is incorrect.
Based on the explanations above, the correct answer is option c. Motion parallax is not detected because of binocular disparity, but rather due to the perception of relative motion.
