The Basic Idea
When you’re waiting to make a left turn at the traffic light, and it suddenly starts flashing green, you’re likely not interpreting every bulb of green light individually. You’re likely perceiving the configuration of lights as a whole in the shape of an arrow.
Similarly, when you hear a song that’s been transposed in a different key, you’re still able to identify the same song even though each individual note is different from the original version.
Our brains have the incredible ability to perceive large configurations of stimuli despite the uniqueness of their components, and they can do so in very predictable ways. This is the insight that lies at the base of Gestalt psychology, a school of thought that emphasizes the idea that the ‘wholes’— patterns we make of individual stimuli— shape perceptual organization and transcend the sum of their parts.
There are wholes, the behavior of which is not determined by that of their individual elements, but where the part-processes are themselves determined by the intrinsic nature of the whole. It is the hope of Gestalt theory to determine the nature of such wholes.
– Max Wertheimer
