Final answer:
The feature comparison model focuses on shared features among category members, while the prototype approach emphasizes typical category members.
Step-by-step explanation:
The feature comparison model and the prototype approach are two cognitive models used to categorize concepts. The main difference between them is that the feature comparison model focuses on shared features among category members, while the prototype approach emphasizes typical category members.
The feature comparison model assumes that categories have graded structures, meaning that some category members are more central and representative than others. On the other hand, the prototype approach assumes that categories do not have graded structures, and instead focuses on identifying the best example or representation of a concept, known as a prototype.
Based on these differences, the feature comparison model is more suitable for complex, abstract concepts that can be differentiated by their shared features, while the prototype approach is useful for identifying typical category members.
