Final answer:
The precision of knowledge representation (KR) can vary with the stage of learning. Studies suggest that as individuals gain more expertise, their ability to categorize knowledge at a more precise level improves.
Step-by-step explanation:
The precision of knowledge representation (KR) may vary depending on the stage of learning. The given information from Johnson and Mervis (1997) suggests that the level of expertise can affect the basic level of categorization. As learners gain more expertise, their ability to categorize knowledge at a more precise and specific level improves.
For example, in the study by Tanaka and Taylor (1991), experts in a particular field were able to categorize objects at a more detailed level compared to novices. This indicates that as individuals become more knowledgeable and experienced in a specific domain, their precision in knowledge representation tends to increase.
The referenced studies provide insights into how the precision of KR can vary with the stage of learning. However, it is important to consider that individual differences and other factors may influence the relationship between expertise and precision in knowledge representation.
