Natural and Artificial Concepts
In psychology, concepts can be divided into two categories, natural and artificial.
natural concepts
Natural concepts are concepts we form through experience—either direct (hands-on) or indirect (through media, conversations, or stories).
For example, consider the concept of snow:
- If you grew up in Essex Junction, Vermont, you have direct experience: watching snow fall, shoveling it, sledding, or packing perfect snowballs.
- If you grew up on Saint Vincent in the Caribbean, you may have never touched snow. Instead, your concept develops from indirect experience: pictures, movies, books, or descriptions from others.
In both cases, you can build a concept of snow, but the richness and detail of the concept depend on your personal experience.
Natural concepts are “fuzzy.” They do not have strict boundaries, and individuals may form slightly different versions based on their own backgrounds and cultures.

artificial concept
Artificial concepts are defined by a specific set of rules or features. They have clear boundaries and consistent characteristics
Examples of artificial concepts include:
- Geometric shapes:
- A triangle always has three sides.
- A square always has four equal sides and four right angles.
- Mathematical formulas:
- The concept of area (length × width) applies only when certain conditions are met.
- Legal and scientific definitions:
- Citizenship, chemical classifications, diagnostic criteria—all rely on agreed-upon rules.
Because artificial concepts have rigid structures, they are especially useful for teaching, communication, and advanced thinking. Artificial concepts often build on one another:
- You must first understand what a square is.
- Then you can learn the area of a square.
- With that foundation, you can learn to calculate the area of other shapes.
As Goldstone and Kersten (2003) explain, concepts act as building blocks, combining in countless ways to support complex reasoning and problem-solving.
