Final answer:
The theory that best fits the definition related to concepts' role within theories and conceptual networks is 'Theory Based Concepts'.
Step-by-step explanation:
The theory that fits the definition where concepts are not just based on definitions but also on the role they play within theories and conceptual networks is Theory Based Concepts. Concepts can be incredibly diverse, embodying complex and abstract constructs like 'justice' or more concrete elements like 'types of birds'. Within psychology, we see the application of concepts in frameworks like Piaget's stages of development. Concepts such as tolerance, for instance, have become commonly understood due to their widespread usage and conceptual evolution over time.
Concepts are a core part of how we organize thoughts and are essential to communication and complex thinking. We differentiate between natural and artificial concepts, with the former being derived from experiential understanding and the latter defined by a fixed set of characteristics. For example, our concept of snow is a natural concept while the parameters that define geometric shapes like squares and triangles are deemed artificial concepts.
