A tips from Memory Improvement is Closing your eyes when trying to recall events raises the chances of researchers, accuracy at Surrey University advice.
Experts tested people capability to remember details of movies showing bad crime scenes.
The hope the studies will support witness recall details more perfectly when questioned by police.
They say establishing a rapport with the person asking the questions can also support improve memory.
Writing in the Legal and d Criminological Psychology journal, experts tested 178 participants in 2 separate experiments.
In the first, they asked volunteers to watch a movie showing an electrician entering a home, carrying our job and then stealing a number of things.
Volunteers were than questioned in 1 of 4 groups. People were either asked questions with their eyes closed or open, and after a sense of rapport had been built with the interviewer or no attempt had been made to make a friendly introduction.
People who had some rapport with the interviewer and had their eyes close throughout questioning replied 3 quarters of the 17 questions perfectly.
But those who did not have a welcoming introduction with the interviewers and had their eyes open replied 41% perfectly.
The analysis presented that eye closing had the powerful impact on remembering details perfectly but that feeling best during the interview also helped.
In the 2nd experiment, people were asked to remember facts what they had heard during a mock crime scene.
Again shut their eyes and having a sense of rapport with the interviewer support people recall more details then participants in all other groups.
Dr Robert Nash (Lead researcher), said: “Our figures and other figures before us points towards eye closure supporting because it removes distraction.
“Closing your eyes might also support people visualise the details of the event they are trying to remember, but our 2nd experiment advises keeping your eyes close can support focus on audio detail too.
The mechanisms we identified ought to apply to other contexts, for instance trying to remember lecture details.
Prof Tim Hollins, University of Plymouth, offered an independent comment” This adds to the rising body research that eye closure might be helpful idea that police may want to use.
The other perfect thing about this piece of job is that they have looked a rapport building too.
This data presents the advantage of eye closure and rapport building added combine rather than cancelled each other out as some people previously terror.
