Which of the following statements regarding depth perception is true
A-Texture gradient is a monocular cue
B-Motion parallax is detected because humans perceive binocular disparity
C-Experience teaches people to perceive relative size as an indicator of the color of an object
D-The change in position of an object relative to the retina is a binocular cue
A-Texture gradient is a monocular cue is the true statement regarding depth perception.
The correct statement is:
A- Texture gradient is a monocular cue.
Texture gradient is a monocular cue for depth perception. Monocular cues only require information from one eye to perceive depth. The texture gradient refers to the way that the pattern of a surface changes as it extends into the distance. As objects recede into the distance, they appear closer together and their details become less apparent. This gradient of texture provides our visual system with information about the relative depth of objects in a scene.
To determine which statement regarding depth perception is true, let's analyze each option.
A- Texture gradient is a monocular cue: To understand this, we need to know that depth perception is the ability to perceive the relative distance of objects in the three-dimensional space. Texture gradient refers to the gradual change in the texture of a surface as it recedes into the distance. This visual cue helps us perceive depth. Now, is it a monocular cue? Monocular cues are depth cues that can be perceived with only one eye. Texture gradient is indeed a monocular cue because we can still perceive depth even if we close one eye or observe a picture with just one eye.
B- Motion parallax is detected because humans perceive binocular disparity: Motion parallax is a monocular depth cue that allows us to perceive depth by observing the relative motion of objects as we move. Binocular disparity, on the other hand, refers to the slight difference between the images seen by each eye. Therefore, these two are different cues. So, statement B is not true.
C- Experience teaches people to perceive relative size as an indicator of the color of an object: This statement is unrelated to depth perception. It suggests that relative size can be used to determine the color of an object, which is not accurate. Therefore, statement C is not true.
D- The change in position of an object relative to the retina is a binocular cue: The change in position of an object relative to the retina is also known as retinal disparity. It occurs because each eye sees the world from a slightly different angle, allowing us to perceive depth. This is a binocular cue as it requires information from both eyes to perceive depth accurately. So, statement D is true.
In conclusion, the correct statement regarding depth perception is D- The change in position of an object relative to the retina is a binocular cue.
