Sensory and Perceptual Contributions to the Preparation and Execution of Goal-Directed Action

例如，假设我伸手去拍桌子上的一只苍蝇，但没有拍到，如果我再试一次，我可以使用什么类型的错误信号来更新和调整我的下一次尝试？我对错误信号的意识是否会影响我认为是错误的来源，例如，我错过了，因为苍蝇移动或我在我的范围内犯了一个错误？如果我没注意，苍蝇落在我手背上怎么办？不用看，我能轻易地知道苍蝇落在哪只手上吗？手的位置如何影响我找到苍蝇的速度？如果我决定，还是不看，试着用我的另一只手拍苍蝇，我对我的手（上面有苍蝇）在空间中的位置的感觉有多准确？我使用什么信息来计划我的伸手去拍苍蝇，我多快可以做出决定？*拟议的研究旨在解决这些类型的问题。我们的大脑和感觉运动系统的能力，以适应检测和纠正运动错误，完善我们的行动，并调整到不断变化的条件下，在环境和/或神经肌肉系统是很重要的，以采取行动，并与世界互动。这项研究计划的长期目标是更好地了解感官和感知运动对目标导向行动的准备和控制的作用机制。我试图了解的原则，管理的控制和适应目标导向的运动在面对系统的扰动的感觉/感知环境和/或效应器机械。*****

Consider, for instance, that I reach to swat a fly on my desk and miss it. If I try again, what type of error signal can I use to update and adjust my next attempt? Does my awareness of the error signal influence what I think is the source of the error for example, did I miss because the fly moved or I made a error in my reach?******What happens if, while I'm not looking, the fly lands on the back of my hand? How easily can I tell, without looking, which hand the fly has landed on? How will the location of my hand affect how quickly I can locate the fly? If I decide, again without looking, to try and swat the fly with my other hand, how accurate is my sense of where my hand (with the fly on it) is in space? What information do I use to plan my reach to swat the fly, and how quickly can I make my decision?******The proposed research is designed to address these types of questions. The capacity of our brain and sensorimotor system to adapt to detect and correct movement error, to refine our actions and adjust to changing conditions in the environment and/or neuromuscular system is important to act upon and interact with the world.******The long-term objective of this research program is to better understand the mechanisms underlying the sensory and perceptual-motor contributions to the preparation and control of goal-directed actions. I seek to understand the principles that govern the control and adaptation of goal-directed movements in the face of systematic perturbations to the sensory/perceptual environment and/or the effector machinery. *****
