When are moving images remembered better? Study–test congruence and the dynamic superiority effect

Abstract

It has previously been shown that moving images are remembered better than static ones. In two experiments, we investigated the basis for this dynamic superiority effect. Participants studied scenes presented as a single static image, a sequence of still images, or a moving video clip, and 3 days later completed a recognition test in which familiar and novel scenes were presented in all three formats. We found a marked congruency effect: For a given study format, accuracy was highest when test items were shown in the same format. Neither the dynamic superiority effect nor the study–test congruency effect was affected by encoding (Experiment 1) or retrieval (Experiment 2) manipulations, suggesting that these effects are relatively impervious to strategic control. The results demonstrate that the spatio-temporal properties of complex, realistic scenes are preserved in long-term memory.

Notes

¹ The fact that study–test congruence yielded higher discriminability for each study mode does not imply that study–test congruence yields the best performance across all study and test modes. Indeed, d _a in the incongruent moving/multistatic condition was (nonsignificantly) higher than that in the congruent multistatic/multistatic condition in Experiment 1, t(71) = 1.41, p = .16.
