Final answer:
Repeating what an instructor says to write it down word for word is a practice involving the self-referencing effect, enhancing memory by making information more distinctive.
Step-by-step explanation:
When you repeat to yourself what your instructor just said in order to write it down word for word, this is an example of the self-referencing effect. Specifically, it's an application of saying words you want to remember out loud to yourself, which is known to improve memory for the words due to their increased distinctiveness, as was discovered in studies like those by MacLeod, Gopie, Hourihan, Neary, & Ozubko (2010). This act of repetition helps to enhance memory retention by making the information more personal and easier to recall.
