项目摘要

DESCRIPTION (provided by applicant): An emerging movement within cognitive neuroscience posits that many cognitive processes are a product of goal-directed interactions between actors and environments. A complementary view is the theory of "motor facilitation", which maintains that viewing an object activates the appropriate movements for interacting with it. Thus hypothesized is a strong bi-directional link between conceptual representations of objects and goal- directed actions. Due in part to the novelty of this area of investigation, relevant theories are for the most part highly unconstrained. This proposal makes use of our conceptual model of object-related actions, the 2 Action System model, to frame a theoretically- driven set of predictions that will be tested in an interdigitated series of studies with patients with stroke and cortico-basal ganglionic degeneration syndrome, both of whom exhibit high-level action disorders, healthy subjects, detailed neuroimaging analyses, and transcranial magnetic stimulation. One of the critical hypotheses to be tested is that different types of action representations may be activated under different task demands, with differing predicted time courses, and based upon distinct neuroanatomic substrates. Also to be tested are predictions related to a hypothesized set of constraints on the relationship of motor competence and conceptual organization. Finally, several experiments will relate individual differences in the current status of the motor system, and underlying integrity of brain structures involved in motor planning and execution, to a) activation of previously-existing, natural conceptual representations and b) the ability to develop artificial conceptual object and action representations. These studies will test the hypothesis that the competence of the motor system has highly circumscribed and predicted relevance for both natural concept retrieval as well as artificial concept learning. The proposed work is expected to have broad significance for theories of "selection for action" and "embodied cognition", as well as for accounts of higher-level disorders of motor control. Specifically, the proposed work will 1) provide critical constraints on the contexts in which bidirectional links are observed at the conceptual- motor interface, 2) elucidate the precise representational structure and time-course of activation of object and action representations, 3) anchor relevant constructs in a detailed cognitive-neuroanatomic model, and 4) clarify the nature of conceptual-motor impairments of patients with high-level (cognitive) action disorders.
描述(由申请人提供):认知神经科学中的一个新兴运动假定许多认知过程是行为者和环境之间目标导向的相互作用的产物。另一个补充观点是“运动促进”理论,该理论认为,观看物体会激活与之互动的适当运动,因此假设物体的概念表征与目标导向的动作之间存在强有力的双向联系。部分由于这一研究领域的新奇,相关理论在很大程度上是高度不受约束的。该建议利用我们的目标相关行为的概念模型,即2行为系统模型,来构建一组理论驱动的预测,这些预测将在一系列交叉研究中进行测试,这些研究涉及中风和皮质基底神经节变性综合征患者,他们都表现出高水平的行为障碍,健康受试者,详细的神经影像学分析和经颅磁刺激。其中一个关键的假设是,不同类型的动作表征可能会被激活不同的任务需求,不同的预测时间过程,并根据不同的神经解剖基板。也要测试的预测有关的一组假设的约束关系的运动能力和概念组织。最后,几个实验将运动系统当前状态的个体差异,以及参与运动规划和执行的大脑结构的潜在完整性与a)先前存在的自然概念表征的激活和B)开发人工概念对象和动作表征的能力联系起来。这些研究将测试这一假设,即运动系统的能力具有高度限制和预测的相关性,为自然概念检索以及人工概念学习。这项工作将对“行为选择”和“具身认知”理论以及更高层次的运动控制障碍的解释具有广泛的意义。具体而言,拟议的工作将1)提供关键的约束条件的情况下,双向链接观察在概念-运动接口,2)阐明精确的表征结构和时间过程的激活对象和行动的代表,3)锚相关的结构在一个详细的认知神经解剖模型,4)阐明高水平(认知)动作障碍患者的概念运动障碍的性质。
