Imagine that the students described below are all taking a multiple choice test. Which student's behavior best describes an example of implicit memory?
a. One student comes to a question for which he is unsure of the answer, but choice b seems familiar so he decides that it must be right.
b. One student remembers the correct answer to a question as well as where the information could be found in his notebook.
c. One student has no idea what an answer was supposed to be, but she does not want to leave a question blank. So, she guesses by first writing out items that she thought would make sense.
d. One student is sure he does not know the answer for a question, so he leaves it blank.
