A recent study has found that people who takes notes are more likely to forget the information they are presented with if they write it down compared to those who don't.
Researchers from Mount St Vincent University in Canada took two groups of participants to play the game Concentration - the "memory card game in which the identity and location of pairs of cards need to be remembered".
They have gave one group a pen and some paper and left the other group without - half way through the game, the group with the pen and paper had their notes unexpectedly taken away from them.
By the end of the game, the group without notes throughout had performed significantly better.
The findings, published in the Memory & Cognition journal, suggest that the human brain "intentionally forgets" information it thinks is safely stored elsewhere.
