The ratio rule relates the recency effect in free recall to the ratio of the duration of the inter item presentation interval (IPI) and the retention interval (RI). Three experiments examined this ratio rule in an immediate memory setting. An approximately linear relationship was discovered to hold over ratios ranging from 1:12 to 12:1 (Experiment 1), and also for constant ratios ranging from 1:1 to 12:12 (Experiments 2 and 3). However, in contrast to a "true" ratio rule, recency systematically decreased with increases in absolute duration, despite a constant IPI to RI ratio. A new distinctiveness model is proposed that accurately predicts the reported empirical relationships. The model incorporates a precise definition of stimulus distinctiveness, based on the dimensional distinctiveness model, and includes a specific mechanism to account for how the distinctiveness of each item arises, based on the perturbation model. @ 1997 Academic Press
