Final answer:
The Gestalt rules for organizing perception are called 'proximity' for grouping nearby objects and 'similarity' for grouping like objects together.
Step-by-step explanation:
The Gestalt rule describing the perceptual tendency to see objects that are near each other as belonging to a set is termed proximity; while the tendency to see like objects as belonging together is termed similarity. These principles are part of the Gestalt psychology's approach to understanding how we perceive patterns and organize sensory information. When objects are physically close, our perception tends to group them into a unit, demonstrated in the Gestalt principle of proximity. Similarly, the Gestalt principle of similarity suggests that items that share visual characteristics such as shape, size, color, or texture, are seen as belonging to a set. For example, we might see a cluster of stars as a constellation because of proximity, or we might group leaves of the same tree species together because they are similar.
