Humans have the ability to produce an internal reproduction of a specific motor action without any overt motor output. Recent findings show that the processes underlying motor imagery are similar to those active during motor execution and both share common neural substrates. This suggests that the imagery of motor movements might play an important role in acquiring new motor skills.

Article Synopsis
- Humans have a remarkable ability to adapt their movements, which is important for both robotics and neuroscience studies.
- This research explores using motor imagery techniques to enhance learning in a robot-based task that involves a mixed force field with both velocity and position components.
- Findings indicate that mental practice can positively affect motor learning and potentially speed up the adaptation process during rehabilitation.

In this paper, we investigate motor adaptation of human arm movements to external dynamics. In an experiment, we tried to determine whether humans can learn an internal model of a mixed force field (V+P) that was the sum of a velocity-dependent force field (V) and a position-dependent force field (P). The experimental results show that the subjects did not learn the internal model of V+P accurately and they compensated for the loads by using impedance control.
