Final answer:
The statement that observer centered cues decrease in effectiveness as distance increases is true.
Step-by-step explanation:
Observer centered cues, such as stereo vision and motion parallax, are more effective at shorter distances. For example, the closer an object is, the greater the disparity between the two retinal images in stereo vision, which helps in judging distance. Conversely, at larger distances, these cues become less effective because the disparity decreases and the parallax effect is minimized.
When considering an object at a distance, its size on the retina diminishes, making it appear smaller (If something is far away, then it will appear smaller). Additionally, motion-related effects, such as the Doppler effect, illustrate that relative motion impacts perceived frequency: An object moving toward the observer increases perceived frequency, whereas one moving away decreases it (Relative motion apart decreases the perceived frequency).
These principles are essential in understanding perception and the physical properties of waves and motion, which are foundational topics in physics.
