Final answer:
People are inclined to think of specific information sources when required to memorize details that will be made inaccessible.
Step-by-step explanation:
The discussion of the experiments suggests that people are inclined to think of specific information sources in response to being required to memorize details that will then be made inaccessible. This is because people tend to rely on specific sources of information when retrieving information from memory. For example, if we are asked to recall specific details that we have memorized, we are more likely to think of the source from which we learned those details.
