What is mental rehearsal?
Sources:
Mental rehearsal, also known as visualization, involves imagining the performance of a specific skill or action without physically doing it. According to , mental rehearsal engages the upper motor neurons, which are responsible for generating commands for movement, similar to actual physical activity. This method can improve strength and skill acquisition, although the improvements are generally not as significant as those from actual physical practice 1 2.
Huberman emphasizes that mental rehearsal is most effective when used as a supplement to physical training rather than a replacement. For example, visualizing muscle contractions or skill sequences can enhance your ability to perform these actions in real life by increasing the frequency and accuracy of correct performance 3 4.
Additionally, the effectiveness of mental rehearsal can vary depending on one's ability to visualize. Some people naturally find it easier to mentally simulate actions than others, but this skill can be improved with practice 3 5.
In summary:
- Mental rehearsal activates upper motor neurons, aiding in skill and strength acquisition.
- It is most effective as a supplement to physical practice, not a replacement.
- Individual ability to visualize can vary but can be improved with practice.
