Final answer:
Experts are just as good at subordinate level categorization as they are at basic level categorization.
Step-by-step explanation:
In regards to how expertise affects categorization, the statement that experts are just as good at subordinate level categorization as they are at basic level categorization is true (option D).
Research studies such as the one conducted by Johnson and Mervis (1997) have shown that experts are able to categorize items at both basic and subordinate levels with similar accuracy and speed. This is because experts have acquired extensive knowledge and experience in their field, which allows them to recognize subtle differences and make nuanced categorizations.
Alternatively, novices tend to perform better with basic categorization tasks than experts (option B) and are faster at basic categorization tasks than at subordinate categorization tasks (option C).
