Research on Memory Processes Shows Us That When Tested on a Recently

Research on memory processes shows us that when tested on a recently learned word list, the majority of people will recall the words at the end of the list at a higher rate than the words in the middle of the list. This "recency effect" can be eliminated by involving the participants in a task that stops them from rehearsing the words. Using this principle, before Dr. Brown gives an exam, she asks that all books and notes be put away and then takes time to prevent the "recency effect" by giving the instructions for the exam, the
Grading procedures, and next week's lesson topic before allowing students to begin the exam. In this case, Dr. Brown is:

A) collecting applied research data in her class.
B) relying on students' short-term memory to help them out.
C) increasing the chance that students will cheat.
D) applying basic research principles in her course.
