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，却没拍到。如果我再次尝试，我可以使用什么类型的错误信号来更新和调整我的后续尝试？我对错误信号的意识是否会影响我如何以及是否调整我的覆盖面？我对错误信号的意识是否会影响我对错误来源的看法——例如，我错过了是因为苍蝇移动还是我犯了一个移动错误？我是否有意识地控制我的触手，或者我是否能够无意识地纠正它，这有关系吗？该研究的长期目标是了解在面对感觉/知觉环境和/或效应机制的系统干扰时，控制目标导向到达运动的适应原则。我们的感觉运动系统的适应能力——检测和纠正运动错误，改进我们的行动，适应环境和/或神经肌肉系统不断变化的条件——对行动和与世界互动很重要。本研究的目的是解决上述例子中提出的问题类型，并促进我们对感觉运动适应的理解。

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 subsequent attempt? Does my conscious awareness of the error signal influence how and whether I adapt my reach? 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 movement error? Does it matter whether or not I consciously control my reach or if I am able to unconsciously correct it? The long-term objective of the proposed research is to understand the principles that govern the adaptation of goal-directed reaching movements in the face of systematic disturbances to the sensory/perceptual environment and/or the effector machinery. The capacity of our 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 aim of the proposed research is to address the types of questions raised in the example above, and to contribute to, and further our understanding of sensorimotor adaptation.
