Shutting Your Eyes Enhances Accurate Recall Capabilities
A Fresh Glimpse at Memory:
Losing your car keys in a frenzy or struggling to remember key details can seem like a hassle, but a new research twist suggests closing your eyes might just be the secret trick to boosting your short-term memory.
Exciting findings from the University of Surrey in the UK reveal that shutting off visual distractions could make a significant difference in memory retention.
It's not just a quirky hack for everyday life; it could positively impact real-life scenarios.
For instance, an eyewitness to a crime who closes their eyes while recalling events may provide more accurate testimony, potentially contributing to better justice outcomes.
Why Closing Your Eyes Boosts Memory
Dr. Robert Nash, the leading researcher behind the study, explains that shutting your peepers helps you visualize details from your past more vividly and even improves auditory recall.
By eliminating distractions, you can focus on specific sensory details that might otherwise slip your mind.
To test this theory, the researchers conducted two experiments with a total of 178 participants.
In the first experiment, participants watched a silent film showing an electrician entering a house, performing his job, and swiping possessions. The research group instructed one set of participants to close their eyes while answering questions about the clip, while the other group kept their eyes wide open.
The results? A staggering 71% success rate for the eyes-closed gang, compared to a mediocre 48% for their sighted counterparts.
In a second experiment, participants watched a British crime show featuring an elderly man being attacked in his home. Researchers evaluated both visual and auditory recall. Again, those who closed their eyes outperformed the open-eyed bunch.
Shaking Up Eyewitness Testimony Concepts
Many assume the human memory operates like a video camera, recording and retrieving information as needed. However, research consistently reveals that memory is fallible, especially when confronted by external factors like stress, leading questions, or distractions.
Traditional police investigations rely heavily on eyewitness testimony, yet research has exposed that even cooperative witnesses can struggle to remember crucial details.
The University of Surrey's study underscores how a simple step, like closing one's eyes, can considerably improve recall accuracy.
This finding carries significant relevance, given the ongoing debate over the validity of eyewitness testimony in legal settings.
The criminal justice system often places enormous faith in eyewitness accounts, even though they can be distorted by factors like poor lighting, brief exposure, and emotional trauma.
The Bonding Effect on Memory Recall
Another key finding from the study was the role of building rapport in enhancing recall. Researchers discovered that participants who felt comfortable and trusted their interviewers recalled details more effectively.
This suggests that effective police questioning techniques should encompass both rapport-building and encouraging witnesses to close their eyes.
At present, many law enforcement agencies receive minimal training in proper witness interview techniques.
This research underscores the necessity of structured interview methods prioritizing witness comfort and memory recall accuracy.
Memory Manipulation’s Dark Side
While closing your eyes can strengthen recall, another study was published the same week, revealing that memory can be manipulated under certain conditions.
Researchers found that innocent individuals could be persuaded to believe they had committed crimes through mental trickery and improper questioning.
Shockingly, after just three hours of psychologically manipulative questioning, some participants started to genuinely believe they had committed serious crimes during their adolescent years.
This development raises concerns about how law enforcement officers interrogate suspects. If memory can be distorted so easily, how many wrongful convictions have resulted from misleading questions or manipulation?
The Future of Eyewitness Testimony
The University of Surrey's study emphasizes a crucial point: how we retrieve memories is essential.
Minor changes, like closing one’s eyes or ensuring a witness feels secure, can have profound consequences for the accuracy of testimony.
As legal experts and psychologists refine best practices for police interviews, simple techniques like these could aid in preventing wrongful convictions and improve the reliability of eyewitness testimony.
The next time you misplace your phone or require assistance remembering an essential detail, give your eyes a rest and let your brain take over.
It could work better than you think.

Overall:
Closing one’s eyes during memory tasks can enhance short-term memory by reducing distractions, promoting internal focus, and facilitating mental imagery. While the immediate impact of eyes-closed memory recall is not scrutinized in all current memory studies, insights into visual attention and memory systems offer valuable insights.
Reduced Distraction and Enhanced Attention
- Limited Environmental Interference: Closing the eyes reduces extraneous stimuli, allowing attention to focus more solely on memory retrieval, aligning with the multi-store model of memory, in which distraction hamper recall.[4]
- Promoting Internal Focus: Inner thoughts and imaginative processes rely on internal representation networks rather than the external environment. Closing the eyes can help individuals focus on these internal processes.
Mental Imagery and Eyewitness Implications
- Visual Imagery and Memories: Visual short-term memory involves retaining and manipulating images in the mind. Closing one's eyes supports this mental imaging, potentially improving recall.
- Mental Rehearsal Relevance: Closing the eyes may create a brief window in which mental rehearsal is less likely to be interrupted, potentially boosting retention for the last items presented (recency effect).[4]
Eyewitness Testimony and Recall Accuracy
- Reduced Irrelevant Stimuli: In high-pressure situations, closing one’s eyes may help eyewitnesses filter out non-essential information, focusing on the memory of the event.
- Combined Physiological Indicators: Eyes-closed recall in conjunction with physiological measures like pupil dilation could offer new ways to assess memory accuracy in legal and educational contexts. Research suggests that pupil responses during recall reflect familiarity and accuracy of remembered details, which could be beneficial in court settings.[1][5]
- Parallels with Memory Consolidation: Animal studies indicate that memory processing continues during sleep, with pupil behavior reflecting ongoing memory consolidation.[5] While not identical, enhanced memory performance with eyes closed may resemble these processes, allowing the brain to focus on internal memory work.
Science and health-and-wellness research highlight the potential benefits of mental-health practices for improving memory. A study conducted by the University of Surrey found that closing one's eyes can significantly boost short-term memory, as it reduces distractions, promotes internal focus, and facilitates mental imagery. In the realm of health-and-wellness, mental-health techniques like closing one's eyes could potentially aid in preventing memory issues and even contribute to more accurate recall in real-life scenarios, such as in eyewitness testimonies.
