Final answer:
Reversible figure-ground relationships are the best illustration of the same stimulus pattern triggering more than one perception.
Step-by-step explanation:
The best illustration of the same stimulus pattern triggering more than one perception is reversible figure-ground relationships. Reversible figure-ground relationships occur when the same visual stimulus can be perceived as either the figure or the background, depending on how our brain interprets it. For example, the classic figure-ground image of the vase and two faces can be perceived as either the vase or the faces, demonstrating that the same stimulus can trigger different perceptions.
