Effortless learning during sleep is the dream of many people.
The supportive effect of smells on learning success when presented both during learning and sleep was first proven in an extensive sleep laboratory study. Researchers at the University of Freiburg – Medical Center, the Freiburg Institute for Frontier Areas of Psychology and Mental Health (IGPP) and the Faculty of Biology at the University of Freiburg have now shown that this effect can be also achieved very easily outside the lab.
For the study, pupils in two school classes learned English vocabulary – with and without scent sticks during the learning period and also at night. The students remembered the vocabulary much better with a scent.
