Impairments in Motor Cognition: Examining alternative routes to action

点击翻译按钮获取中文摘要

The proposed studies investigate effects of stroke and limb apraxia as well as aging on motor cognition, specifically on selecting actions. The work-program includes fundamental studies with healthy participants, yet it is predominantly oriented towards applications in patients, with the aim to offer implications for diagnostic and rehabilitative approaches. The goal is to investigate two concepts that may reduce the load on impaired behavioral and neural components of motor cognition in stroke patients. Firstly, alternative routes to the same action will be studied, and secondly, interfering carry-over effects of prior executed actions on the subsequent movements will be analyzed. A recently developed paradigm will be applied that makes use of rule and plan-based action selection.
