Evaluation of Experimenter-Supplied and Subject-Originated First-Letter Mnemonics in a Free-Recall Task

The purpose of this experiment was to determine whether supplying Ss with a mnemonic device produced a differential retention effect as opposed to letting Ss originate their own device when using a first-letter mnemonic technique in a free-recall situation. No difference in the recall of a list of 19 nouns existed at the immediate retention test, but Ss with an E-supplied scheme showed significantly better recall than those with S-originated schemes at 1-day, 1-wk., and 4-wk. retention intervals. It was concluded that the E-supplied first-letter mnemonic excelled S-originated ones as an effective aid to free recall.
