Do your movements have a “mind” of their own? When watching leads to unintended doing



Many movements we perform on a daily basis are preplanned in our brains well before we intend to execute them. For example, when a sprinter takes the blocks in a race, they have a very good idea of what movements they need to produce when the starting signal is heard. If this starting sound is above a certain level (124 dB) it may elicit what is called a startle response.

It’s not enough just to feel or see what’s correct, you need to 'actively' experience



Have you ever wondered how effective it is to physically guide a person through an action? In sports, the instructor might hold a person's arm to show them how to hit a golf ball or strike a volleyball serve. In rehabilitation, robotic devices are used to guide a person's limb for therapy purposes. What we and others have shown is that this technique is useful when applied, but that it compromises learning once it is removed. In this study, people practised a novel, two limb coordination movement.
