Question

Introduction about depth cues and motion

Answer 1

Looming, vergence, and relative disparity effect the perception of motion in depth. Looming is basically the rapid expansion in the size of any given image I.e. the image becoming increasingly large on the perceiver's retina as we come close.

While vergence is the simultaneous movement of the pupils of the eyes towards or away from one another while we are focusing.

Individual differences in depth contrast are related to individual differences in the weighting of disparity and perspective in the single-stimulus conditions.
