Lateral Eye Movements Increase False Memory Rates.

Area of Science:

• Cognitive Psychology
• Trauma Studies
• Memory Research

Background:

• Eye movement desensitization and reprocessing (EMDR) is a widely used therapy for posttraumatic stress disorder.
• The precise memory-related effects of EMDR, particularly its core eye movement component, remain largely uninvestigated.

Purpose of the Study:

• To investigate whether the lateral eye movements characteristic of EMDR influence susceptibility to the misinformation effect.
• To assess the impact of EMDR-like eye movements on memory accuracy in a simulated eyewitness scenario.

Main Methods:

• A misinformation paradigm was employed with 82 undergraduate participants.
• Participants viewed a video of a car crash and were then divided into two groups: one performing lateral eye movements and a control group maintaining stationary eyes.
• Following the eye movement manipulation, all participants were exposed to an eyewitness narrative containing misinformation.

Main Results:

• Participants who performed eye movements demonstrated reduced accuracy in recalling the video details compared to the control group.
• The eye movement group exhibited a greater susceptibility to the misinformation effect, incorporating false details from the narrative into their memory.

Conclusions:

• Lateral eye movements, as utilized in EMDR, may impair memory accuracy and increase vulnerability to misinformation.
• These findings suggest potential risks associated with EMDR in contexts involving eyewitness testimony, highlighting the need for further investigation.
