Question

Quizplus · Accepted Answer

Depth perception is the ability to perceive the distance of an object or surface from the observer. This is necessary for activities such as climbing and descending stairs, where depth perception helps us judge the height and location of each step to avoid stumbling or missteps. Shape continuity refers to the ability to perceive an object as continuous despite changes in position or appearance, and is not directly related to stair-climbing. Binocular disparity refers to the differences in the images received by each eye, which our brain interprets to create 3D depth perception. While binocular disparity is related to depth perception, it is not the best choice for this particular scenario. Serial perspective is not a recognized term in psychology or perception.
