After studying 178 participants across two studies, the team also discovered that building a rapport also helped witnesses to remember more."It is clear from our research that closing the eyes and building rapport help with witness recall," said lead author Robert Nash from University of Surrey.
"Our results show that building rapport makes witnesses more at ease with closing their eyes. That in itself is vital if we are to encourage witnesses to use this helpful technique during interviews," Nash concluded. The study was published in the journal Legal and Criminology Psychology.
