How Sleep Helps Us Remember Names

2^min

People are much better at remembering names if they sleep for up to eight hours after first meeting new people, research suggests.

Researchers found that people were 'significantly better' at remembering faces and names if they were given the chance to sleep for up to eight hours after seeing those faces and names for the first time.

The 14 participants in the study undertook testing in a controlled environment while staying at the Center of Brigham and Women's Hospital (BWH) in the US for Clinical Investigation.

They were shown 20 photos of faces with corresponding names from a database of more than 600 color photographs of adult faces, and asked to memorize them.

Twelve hours later they were then shown the photos again with either a correct or incorrect name. In addition to answering whether or not the correct name was shown, the participants were asked to rate their confidence on a scale of one to nine.

Each participant completed the test twice - once with an interval of sleep in between and once with a period of regular, waking day activities in between.

When given an opportunity to sleep for up to eight hours, the participants properly matched 12 per cent more of the faces and names.
