Practice Research: study shows faster, better learning
Thanks to cognitive researchers we are understanding more and more about how the brain processes information. A practice research study published in January 2016 by Pablo A. Celnik, M.D., looked at how modifications in practice routines can dramatically improve learning.

A good blog article about the study can be found here:
In this study, subjects were tested on how quickly they could learn a new skill (moving a cursor on a computer.)
The volunteers were split into three groups, and each spent 45 minutes practising this. Six hours later, one of the groups was asked to repeat the same training exercise again, while another group performed a slightly different version that required different squeezing force to move the cursor.
The third group only completed the first training session, so they could act as a control.
At the end of the training period, everyone was tested on how accurately and quickly they could perform the new skill, and predictably, the control group did the worst after their one training session. But the surprise was that the group that had repeated the original training session actually did worse on the test compared to those who had mixed things up and trained in new areas – in fact, the group that modified their training did twice as well as those who’d repeated the original skill.
Did you get that? The group with the varied practice routine performed twice as well as the group that received a second training on the skill. It’s interesting to note that the groups that performed the best received a second training 6 hours after the first training.
The idea that varied practice leads to stronger learning is not a new one. The authors of the above study call this phenomenon “reconsolidation;” others call it “interleaving.” It’s not a new idea. In the book How We Learn, Benedict Carey points to two other studies, on badminton and beanbags, that show the same results.

What can musicians take away from these practice research studies?
