Side effects of induced lateral eye movements during aversive ideation
This study examined eye movements and memory accuracy on a visual discrimination task.
Article Abstract
“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.
Highlights:
- Induced eye movements during trauma memory recall is often applied in PTSD treatment.
- We tested whether an analogue dual task procedure reduces objective memory accuracy.
- Recall of a face image was followed by a discrimination task with novel similar faces.
- Eye movements were associated with increased false-positive rates at 24-h follow-up.
- Eye movement interventions may have unwanted effects related to memory accuracy.”
