BACKGROUND AND OBJECTIVES
Eye Movement Desensitization and Reprocessing (EMDR) is a treatment for posttraumatic stress disorder. It uses a dual-task approach, in which patients recall an aversive memory while making lateral eye movements. Research has shown that this 'eye movements' intervention reduces subjective memory vividness and emotionality. This study examined whether it also reduces memory accuracy on a visual discrimination task.
METHODS
Participants (68 undergraduates) underwent an aversive conditioning phase, in which two pictures of male faces were followed by shock. Then they recalled one face with (experimental condition) and one without (control condition) making lateral eye movements. Finally, they completed a stimulus discrimination test with slightly different faces shortly after the intervention and one day later.
RESULTS
Results showed that the eye movements intervention led to increased false-positive rates one day later.
LIMITATIONS
Our intervention targeted newly formed memory rather than consolidated memory.
CONCLUSIONS
The results inform theory about EMDR's mechanisms of change and suggest that the treatment may have side effects regarding memory accuracy.
背景与目的
眼动脱敏再处理（EMDR）是一种创伤后应激障碍的治疗方法。它采用双任务方法，患者在回忆痛苦记忆的同时进行横向眼球运动。研究表明，这种“眼球运动”干预会降低主观记忆的生动度和情绪性。本研究旨在探讨它是否也会降低视觉辨别任务的记忆准确性。
方法
参与者（68 名本科生）经历了一个痛苦的条件反射阶段，在此期间，两张男性面孔的照片后面跟着电击。然后，他们回忆起一张带有（实验组）和一张不带有（对照组）横向眼球运动的面孔。最后，在干预后不久和一天后，他们用略有不同的面孔完成了刺激辨别测试。
结果
结果表明，眼球运动干预导致一天后假阳性率增加。
局限性
我们的干预针对的是新形成的记忆，而不是巩固的记忆。
结论
研究结果为 EMDR 改变机制的理论提供了信息，并表明该治疗可能会对记忆准确性产生副作用。
