AB  - Background: There are mixed findings regarding the effectiveness of selected directed forgetting (SDF). On psychological and physiological grounds, SDF may influence forgetting and subsequent memory enhancement via multiple mechanisms, including, for example, executive control and the Rac1-Cofilin pathway. These mechanistic pathways may also be altered by acute exercise engagement, suggesting that acute exercise may facilitate SDF. Methods: The present novel experiment evaluates this possibility. A four-arm (N=20 per group; Mage=20 yrs), parallel-group randomized controlled experiment was employed. The four groups included: 1) exercise plus SDF (Ex+SDF), 2) SDF only (SDF), 3) DF (directed forgetting) only (DF) and 4) R (remember) only (R). For L1 (List 1), the EX+SDF, SDF, and DF groups recalled fewer items than R, for both red and green items. For L2 (List 2), and for green words, EX+SDF, SDF, and DF recalled more items than R. Results: We observed a significant L1 Item-Type x Cue interaction (F=4.02, P=.01, η2p=.13) and a marginally significant L2 Item-Type x Cue interaction (F=2.73, P=.05, η2p=.10). Conclusion: This experiment provides suggestive evidence for the SDF paradigm. Further, we provide the first examination of whether acute exercise influences SDF. Our findings suggest that acute exercise may facilitate SDF, particularly for L2 enhancement.
