Suppose you (a student) are asked by a teacher to learn a poem you will recite in front of your class. Soon after, both you and a classmate, J. P., are asked by another teacher to learn the lyrics to an unfamiliar song. When you andJ. P. are later asked to remember the song lyrics, you have a much more difficult time recalling them than J. P. does. This impairment of your performance is most likely attributable to:a. proactive interference. b. your overloading the phonological loop. c. a release from proactive interference. d. a recency effect.
