EVERY good UI designer will design elements considering their shape, FORM, size, color, location and alignment. This means that your candidate should understand that element mapping is a crucial part of the design work.

Simply explained, mapping is the implied relationship between controls and their effects. If an element creates an effect that the user expects, then the element has good mapping.

For example, think about a set of IMAGES aligned horizontally that can be MOVED to the left or right. Underneath should be controls or buttons indicating that these images can be moved to either side. To move the images to the left side you would expect to click on the button aligned with the left side. Therefore, actually aligning this button to the left would, indeed, match the user’s expectations, which means this element has good mapping.
