In order to explore the possible contribution of the motor system to the representation of verbs, we studied the relative preservation of the capacity of Parkinson disease patients to name matched sets of object and action pictures. The performance of this group of participants was compared with that of a group of healthy seniors, and a group of Alzheimer disease patients. Generalized linear mixed-effects analyses showed that, whereas the two control groups had similar accuracy scores in response to objects and actions, Parkinson disease patients presented a significant impairment in their capacity to name actions compared to objects. The results of this study support the idea that verb representations are grounded in neural networks to which brain areas involved in motor control contribute.
为了探究运动系统对动词表示的可能贡献，我们研究了帕金森病患者命名匹配的物体和动作图片集的能力的相对保留情况。将该组参与者的表现与一组健康老年人和一组阿尔茨海默病患者的表现进行了比较。广义线性混合效应分析表明，虽然两个对照组在对物体和动作的反应中具有相似的准确性得分，但帕金森病患者在命名动作的能力上明显受损，而在命名物体的能力上则没有明显受损。这项研究的结果支持了这样一种观点，即动词表示是基于涉及运动控制的大脑区域的神经网络的。
