Combining recall of an emotional memory with simultaneous horizontal eye movements (i.e., Recall + EM) reduces memory aversiveness. However, the long-term persistence of this effect is inconsistent across studies. Given that stress may aid in the consolidation of memories, we examined whether acute stress can boost the long-term effects of degraded memories. To test this, participants recalled two negative memories, which were assigned to a Recall + EM or Recall Only condition. Before and after each intervention they rated memory aversiveness (i.e., immediate effects) followed by a stress-induction or control procedure. After a 24h-period, participants rated each memory again (i.e., long-term effects). We found that Recall + EM produces immediate effects but that these effects dissolve over time. Moreover, acute stress did not boost potential long-term effects of Recall + EM. Degraded memories were not retained better by applying stress. We discuss these results and how long-term effectiveness may still be achieved.
将对情绪记忆的回忆与同时进行的水平眼动（即回忆 + 眼动）相结合可降低记忆的厌恶感。然而，该效应的长期持续性在各研究中并不一致。鉴于压力可能有助于记忆巩固，我们研究了急性应激是否能增强衰退记忆的长期效应。为了验证这一点，参与者回忆了两个负面记忆，并将其分配到回忆 + 眼动组或仅回忆组。在每次干预前后，他们对记忆厌恶感进行评分（即即时效应），随后进行应激诱导或对照程序。在24小时后，参与者再次对每个记忆进行评分（即长期效应）。我们发现回忆 + 眼动会产生即时效应，但这些效应会随着时间消失。此外，急性应激并未增强回忆 + 眼动潜在的长期效应。施加压力并不能更好地保留衰退记忆。我们讨论了这些结果以及如何仍可能实现长期有效性。
