Aria is taking an anatomy class and is trying to remember the names of the bones of the skull, specifically the cranial bones. She decides to remember the six bones by using a play on words and comes up with "PEST OF 6." This helped her recall the Parietal, Ethmoid, Sphenoid, Temporal, Occipital, and Frontal (“PEST OF”) bones (there are 6 bones).What technique is best being utilized by Aria?
