Final answer:
The Olympic symbol illustrates the Gestalt principle of similarity, where elements that are similar in shape or form are perceived as part of a group.
Step-by-step explanation:
The Olympic symbol, which is typically perceived as five distinctly colored, interlocked circles, best illustrates the Gestalt principle of similarity. This principle suggests that things that are alike tend to be grouped together. In the case of the Olympic symbol, the circles are perceived as belonging together despite their different colors because they are similar in shape and are evenly spaced, implying a group.
On the other hand, principles like good continuation and proximity also play a role in visual perception, but they refer to our tendency to perceive smooth, continuous lines and to group together elements that are close to each other, respectively. In the context of the Olympic symbol, similarity is the principle that is most directly illustrated.
