Positional similarities are found when elements have similar positions, or have similar "relationships" between themselves. These relations form figures (compound elements) with the similar "characteristic" of being compound elements with like internal relationships.
The spaces between elements, the "relationships" can take on the status of elements in the perceptual field. These spaces are dependent for their definition on the elements. If there is too much space, the relationship can be lost, and the elements be perceived as multiple elements on a field, instead of a single figure.
Balance and equilibrium are examples of positional similarity. The sub-elements of an element have an equal relationship to a particular point or line. The point or line is the axis of symmetry in physical balance, and the central concept or normative reference in intellectual balance.
