It suggests that simplicity and clarity are key elements in creating effective visual communications with strong visual hierarchy, use of spacing-or white space or negative space-and more. In UX design and UI design, the law of Pragnanz has a particularly special place. That fact is extremely helpful when users encounter a graphical user interface (GUI) for a product or service. This way of simplifying what we see lets us process information more easily and efficiently. As the human mind has a natural preference for order and organization over chaos, when presented with visual stimuli, we tend to simplify complex shapes and forms into more recognizable and understandable patterns. There may be varying interpretations of the law or principle of Pragnanz, but it’s generally understood as the law of Simplicity.

As are the principle of uniform connectedness, principle of continuity, principle of closed region, and more. This is also true of the principle of similarity, principle of proximity, and principle of closure. So, the law of Pragnanz is a powerful truth in design, a vital frame of reference, a handy real-world “barometer” for aligning users’ expectations with your business goals, and a kind of tool that your design includes. What’s more, the mind’s lightning-fast perceptions of images mean that the Gestalt laws are timeless. And so is the point that an image is different from the sum of its parts. The effects of some lines or curves are central to this school of psychology. These fields include graphic design and product design, and involve great attention to detail for UX and UI designers.ĭespite these different definitions, the Gestalt school of thought proposes fundamental laws about how a person perceives objects, whatever the medium. That has led to different understandings and descriptions of the concept as it relates to various fields. However, the exact definition and interpretation of Prägnanz have evolved over time. In Wertheimer's 1923 paper on Gestalt theory, he discussed the idea of Prägnanz as a fundamental principle of human perception. The law of Prägnanz (with the umlaut, as spelled in German) is one of the centermost principles of Gestalt psychology. Wertheimer was one of the founders of 1920s’ Gestalt psychology, along with fellow psychologists Wolfgang Köhler and Kurt Koffka. The concept of Prägnanz was the brainchild of Max Wertheimer, a German psychologist. The law of Pragnanz here involves clever interplay between the figure and ground. For example, in the image below, the mind makes sense of the design to see black and white arms and hands in a figure-ground format where the background and foreground work together. Users don’t even have to think about what they’re doing or force the process. This is a quick and automatic process since the human mind dislikes chaos and strives for order. They do so by removing the excess detail from the shapes to make a single, unified whole. Whenever viewers-or users-see complex or highly intricate shapes in a design, their eyes simplify these. The law of Pragnanz is closely related to these categories and serves as a guiding principle for visual perception. Pragnanz is therefore a fundamental part of each product or service you produce.Īccording to Gestalt psychologists, our minds innately tend to perceive patterns using five main categories: proximity, similarity, continuity, closure, and connectedness. From your work on websites to mobile apps, the design elements you include need to “grab” users from the get-go. This is a crucial factor when you as a designer create products. The Gestalt principles of grouping describe how humans perceive visual elements and simplify complex images. It translates to “good figure” or “pithiness.” It also goes by the names “the law of good Gestalt” and “the law of simplicity.” It’s key among the Gestalt principles of grouping and a vital part of graphic design, visual design, user experience (UX) design and-particularly-user interface (UI) design. "Prägnanz" is a German word that spans the concepts of salience, conciseness, and orderliness.
