The Production Effect Interacts With Serial Positions

Reading some words aloud during presentation, that is, producing them, and reading other words silently generate a large memory advantage for words that are produced. This robust within-list production effect is in contrast with the between-lists condition in which all words are read aloud or silently. In a between-lists condition, produced items are better recognized, but not better recalled. The lack of a between-lists production effect with recall tasks has often been presented as one of its defining characteristics and as a benchmark for evaluating models. Recently, Cyr et al. (2021) showed that this occurs because item production interacts with serial positions: Produced items are less well recalled on the first serial positions than silently read items, while the reverse pattern is observed for the recency portion of the curve. However, this pattern was observed with a repeated-measures design, and it may be a by-product of compensatory processes under the control of participants. Here, using a between-participants design, we observed the predicted interaction between production and serial positions. The results further support the Revised Feature Model (RFM) suggesting that produced items are encoded with more modality-dependent distinctive features, therefore benefiting recall. However, the production of the additional distinctive features would disrupt rehearsal.
