Learners were asked to learn pairs of words and were tested immediately, then 6 hours later with a nap in-between. The ‘nappers’ scored 15% higher than the ‘non-nappers’ on the factual test.
There’s something quite interesting emerging in these empirical studies of memory. It would seem that significant increases in retention, perhaps the most fundamental aspect of learning, can come through simple adjustments and additional techniques. With a simple understanding of how knowledge and skills are acquired, stored, rehearsed and recalled, we could make significant advances in productivity.
It is clear that daytime napping is good for the retention of knowledge so I look forward to compulsory naps at school and after training courses. In my experience, in most classroom courses, this happens without much prompting!
