Answer:
The encoding specificity principle.
Step-by-step explanation:
The encoding specificity principle is of the school of thought that memory performance and retrieval is better when memory is tested in the presence of the same cues that were present when the memory was formed. This implies that people tend to perform better when they are tested in the same environment they stayed to learn.
This postulation is countered by another study, which believed that people tend to do better when learning is carried out in different locations than staying at just one.
