the question: Some size/distance cues are useful for distant objects, others for close objects. Provide one example of a cue that would be good for near objects, and one for distant objects. Explain why the cues you have selected would be less useful for objects at other distances (i.e., why the ‘close’ cue is less useful at great distance, and why the ‘distant’ cue is less useful up close).

Question

my answer so far: It can be difficult to determine the true size and distance of an object, but there are some cues to help with this. One cue that is good for near objects is convergence. When an object is closer, the eyes cross in order to look at it. You want the image to appear on the fovea, the center of the retina. Your eyes are some distance apart, so they cross in an attempt to keep the image on the fovea. This cue is less useful for objects at further distances because for objects that are more than twenty feet away, the eyes are nearly parallel and do not cross.

i can't find ANYTHING about cues that are more useful for distant objects and i've been searching for an hour now. help?
