Answer:
John Watson and Pavlov would most approve of the following memory tip:
D) Studying at your desk if that's where you take the test.
Step-by-step explanation:
Our brain does not store data like books or document but like a puzzle. And so retrieving it is not that simple. Recalling a specific event or let us say a topic studied in this case is a completely unconscious process. However, there are things that might slow this process like lack of attention. There are factors that can trigger that specific part of the memory as well. For example, recalling detailed events when we revisit a place we used to go to an year ago.
The tip "Studying at your desk if that's where you take the test" would be most probably approved because memorizing the topics at that place and then giving the test at the same place would help the 'memory retrieving process' trigger more easily.
