Production benefits both recollection and familiarity.

In three experiments, we investigated the roles of recollection and familiarity in the production effect--the finding that words read aloud are remembered better than words read silently. Experiment 1, using the remember/know procedure, and Experiment 2, using the receiver operating characteristic procedure, converged in demonstrating that production enhanced both recollection and familiarity. Experiment 3 supported the role of recollection by demonstrating that specific episodic information--that is, whether a word had been studied aloud or silently--was stronger for items studied aloud. These findings fit with an explanation of the production effect as hinging on two factors: greater recollection of distinctive information from the study episode, and more familiarity due to greater attention allocated to the material studied aloud.
