Allow learners to ‘sleep on it’
If you want learners to remember more, you might want to give them a chance to sleep on what you’ve told them.
According to a recent study, post-learning sleep has a powerful effect on retention.
Researchers conducted an early-morning study during which subjects memorized a series of word pairs.
One group reported back later that same evening for a memory test. The other group returned the following morning.
The subjects who slept after the learning event scored more than 12% higher on the assessment.
Numerous studies have demonstrated sleep’s role in encoding information into long-term memory. This study went further: Researchers found that the brain actively prioritizes information during sleep, deciding what’s worth remembering and what can be safely forgotten.
Takeaway: Schedule training in ways that give learners a chance to sleep on what they’ve learned. For example, instead of one all-day session, consider scheduling an afternoon session followed by another one the next morning.
