than 600 colour photographs of adult faces, and asking them to
memorise. After 12 hours, the photos were shown again with either a
correct or incorrect name. Alongside the photograph test,
participants were also asked to rate their confidence on a scale of
one to nine.

eight hours, participants correctly matched 12 per cent more of the
faces and names.
The researchers said sleep duration or sleep

Dr Duffy said, "As people get older, they are

may in turn cause memory issues.
