Functional neurophysiological basis voluntary action

项目摘要

Humans either cany out actions to produce certain effects in the environment meant to meet the agent s goals; or they carry out actions to accommodate to environmental demands. The first type of action may be referred to as intention-based or voluntary, the latter kind may be referred to as stimulus-based or reactive.Recent research suggests that stimulus- and intention-based actions are controlled by different neural structures. Moreover, the two routes to action work in a different fashion: In the stimulus-based mode, subjects hand over control to the stimuli, in that the system merely acts reflexively upon presentation of a stimulus in a pre-specified way. In this mode, actions are selected with respect to their environmental sensory antecedents. In the intention-based mode, actions are guided by the ideomotor principle. According to the ideomotor theory, voluntary action control is based on learned associations between movements and their perceivable consequences. An intention-based action, so the ideomotor theory, can be triggered by anticipating these consequences.We will investigate the cognitive and neurophysiological basis of stimulus- and intention-based actions along three axes:• Mechanisms of intention-based action control and functional differences between intention- and stimulus-based actions.• Role of distal sensory consequences in intention-based action control.• Coordination of intention- and stimulus-based action.We will approach these issues with the help of techniques coming from two disciplines:• Experimental Psychology and psychophysics (reaction times, detection thresholds).• Neurophysiology (transcranial magnet stimulation [TMS], event-related potentials [ERPs])Our goals are:• to investigate the functional an neurophysiological underpinnings of action control.• to devise and implement new neuroscientific techniques opening up further sophisticated investigation of the topic.• to establish a research axis CNRS LPP / MPI CBS on the topic of neurofunctional antecedents of action control.Because the concept of voluntary action is so pervasive in human sciences, the research will also have wider impact on ethical (accountability) and philosophical issues (free will). Moreover focusing on the sensorimotor basis of voluntary action may help to bridge scientific approaches that are common in health, social, and personality psychology.

人类要么采取行动，在环境中产生一定的影响，以满足代理人的目标;或者他们采取行动，以适应环境的要求。第一种类型的行动可能被称为基于意图或自愿，后一种可能被称为基于刺激或反应。最近的研究表明，基于刺激和基于意图的行动是由不同的神经结构控制的。此外，这两种行动途径以不同的方式工作：在基于刺激的模式中，受试者将控制权交给刺激，因为系统只是以预先指定的方式对刺激进行反射性反应。在这种模式下，动作是根据它们的环境感觉前因来选择的。在基于意图的模式中，行动由表象原则指导。根据表象理论，自愿行动控制是基于运动与其可感知后果之间的习得关联。基于意图的行动，也就是表象理论，可以通过预期这些结果来触发。我们将沿着沿着三个轴来研究基于刺激和意图的行动的认知和神经生理学基础：·基于意图的行动控制机制以及基于意图和基于刺激的行动之间的功能差异。·远端感觉后果在基于意图的行动控制中的作用协调基于意图和刺激的行动。我们将在来自两个学科的技术帮助下处理这些问题：·实验心理学和心理物理学（反应时间，检测阈值）。神经生理学（经颅磁刺激[TMS]，事件相关电位[ERP]）我们的目标是：·研究动作控制的功能和神经生理学基础。设计和实施新的神经科学技术，为该主题的进一步复杂研究开辟道路。由于自愿行为的概念在人类科学中是如此普遍，因此该研究也将对伦理（责任）和哲学问题（自由意志）产生更广泛的影响。此外，专注于自愿行动的感觉运动基础可能有助于弥合健康，社会和人格心理学中常见的科学方法。
