The main principle of gestalt psychology regarding perception is that the sum is greater than the parts. This principle emphasizes that when we perceive a complex scene, we do not merely add up individual components to form a whole. Instead, our mind integrates these parts into a cohesive whole through various organizational rules, such as grouping and figure-ground separation. This means that the human brain tends to perceive objects as organized patterns and whole forms rather than just a collection of simple lines, shapes, and colors.

For instance, when looking at a picture, we see a tree rather than just recognizing brown and green colors and various shapes. The organization of these sensory inputs into a recognizable structure enriches our perception and highlights that the comprehensive interpretation involves more than just individual sensory data. This holistic approach to understanding perception is central to gestalt psychology and plays a significant role in how we experience and interact with our environment.
