Final answer:
Exemplars are a more effective way of understanding category variability than prototypes because exemplars take into account the individual instances within a category rather than representing a single averaged idea, allowing for a more nuanced and diverse comprehension.
Step-by-step explanation:
The statement "Exemplars provide a better way of thinking about the variability of a category than prototypes" is true because while prototypes represent an average or idealized example of a category, exemplars account for the individual instances and variation within that category. Prototypes are based on our most typical experiences and can lead to generalizations and potentially stereotyping, as they might not always encapsulate the full diversity found within a category. Exemplars, however, are actual members of the category that we've encountered, allowing us to consider the full range of possibilities and leading to a more nuanced understanding. For instance, if a Golden Retriever is your prototype for a dog, you might miss the diversity in the category of dogs ranging from Chihuahuas to Great Danes. Thought experiments and the habit of questioning through counterexamples can also help to understand the full breadth of a category, reinforcing the importance of considering exemplars.
