Answer:
C) context-dependent learning.
Explanation:
Context-dependent learning or memory: In psychology, the term context-dependent memory or learning is described as the phenomenon which includes improved recall of particular information or episodes from an individual's memory if the context of the information present at the time of encoding and retrieval are same.
Example: If an individual lost his or her mobile somewhere in office, then the recall will be great in the office place.
In the question above, Dr James is basing this advice on context-dependent learning.
