Imagining performing a movement helps with learning how to physically do the movement. This process, called motor imagery (MI), is thought to help with learning because the same things happen in the brain when you imagine movement as when you physically perform it. Our research suggests that MI is different from physical performance. Knowing how it is different is important. If we know how MI is different, we can use MI more effectively to help people learn new movements. Also, the new knowledge we gain tells us a lot about the ways learning can occur in the brain. We think there are two main differences between MI and physical performance. When you physically practice a movement you get very good at the specific things you practice - if you practice with your right hand, your right hand is really good, but doing the same movement with your left hand results in bad performance. When you practice through MI, performance of the movement is not as good, but you can transfer what you learned - that is you could use your left hand as well as your right. This ability to transfer what you learned makes us think that what you learn through MI is different from physical practice. The other difference is about how you learn. When you physically do a movement, information about how you did the movement is compared to how it was supposed to be done, allowing for errors to be detected and fixed. Because you actually never move in MI, it is not clear if errors are made, detected, and fixed - leading to the question of how MI can help with learning. The proposed projects look to find out more about the kind of learning that results from MI, and what the mechanism is for detecting errors and fixing them. In the first set of projects people will learn a movement through MI or physical practice. Throughout the learning we will test their performance to see if what they are learning is different. We will also record people's brain activity to find out which areas of the brain were active, and how this differs between MI and physical practice. We will also test different combinations of MI and physical practice to see if the kind of learning that MI helps with improves what we learn from physical practice. In the second set of projects we will explore if people make errors when they learn through MI. We will also record people's brain activity to find out what areas are involved in error detection in MI. Finally, using special equipment, we will turn down activity in parts of the brain for a short period of time to find out more about the way that learning occurs in MI. This research will allow us to confirm our ideas about the kind of learning that MI helps with and how learning through MI actually occurs. We need this kind of basic knowledge so we can figure out the best way to use MI to help with learning movement. This will make learning better in a wide range of areas that will ultimately have a positive impact on the health and performance of Canadians.

想象做一个动作有助于学习如何在身体上做这个动作。这个过程被称为运动想象（MI），被认为有助于学习，因为当你想象运动时，大脑中发生的事情与你实际执行运动时发生的事情相同。我们的研究表明，MI不同于身体表现。了解它是如何不同的是很重要的。如果我们知道MI是如何不同的，我们可以更有效地使用MI来帮助人们学习新的动作。此外，我们获得的新知识告诉我们很多关于学习在大脑中发生的方式。 我们认为MI和体能表现之间有两个主要区别。当你身体练习一个动作时，你会非常擅长你练习的特定事情--如果你用右手练习，你的右手真的很好，但用左手做同样的动作会导致糟糕的表现。当你通过MI练习时，动作的表现不是那么好，但你可以转移你所学到的-也就是说，你可以使用你的左手以及你的右手。这种转移你所学知识的能力使我们认为，你通过MI学到的东西不同于身体练习。另一个区别是你如何学习。当你身体做一个动作时，关于你如何做这个动作的信息会与它应该如何做的信息进行比较，从而可以检测和修复错误。因为你实际上永远不会在多元智能中移动，所以不清楚是否会出现、检测和修复错误-这就引出了多元智能如何帮助学习的问题。拟议中的项目希望更多地了解MI导致的学习类型，以及检测错误和修复错误的机制。在第一组项目中，人们将通过MI或身体练习来学习运动。在整个学习过程中，我们将测试他们的表现，看看他们学习的内容是否不同。我们还将记录人们的大脑活动，以找出大脑的哪些区域是活跃的，以及MI和体育锻炼之间的差异。我们还将测试MI和体育锻炼的不同组合，看看MI帮助的学习是否能提高我们从体育锻炼中学到的东西。在第二组项目中，我们将探讨人们在通过多元智能学习时是否会犯错误。我们还将记录人们的大脑活动，以了解MI中哪些区域参与错误检测。最后，使用特殊设备，我们将在短时间内关闭大脑部分的活动，以了解更多关于MI中学习发生的方式。这项研究将使我们能够证实我们关于多元智能有助于学习的类型以及通过多元智能学习实际上是如何发生的想法。我们需要这种基本知识，这样我们才能找到使用MI帮助学习动作的最佳方法。这将使学习更好地在广泛的领域，最终将对加拿大人的健康和表现产生积极的影响。
