这项研究评估了顶叶损伤对学习视觉运动跟踪技能的影响。 30 名患有单一单侧脑损伤的受试者（13 名有顶叶损伤，17 名没有顶叶损伤）和 23 名人口统计相当的健康受试者执行了旋转追踪任务。对于每组来说，四个学习模块中达到目标的时间都显着增加。与其他脑区病变的受试者和健康对照受试者相比，顶叶病变的受试者从第 1 到第 4 块的旋转追踪的改善较小。从第一个到第二个学习块以及从第一个到第三个学习块的任务表现的改进在组之间是相似的。顶叶似乎在获得新的视觉运动跟踪技能中发挥着重要作用，特别是在相对较晚的学习阶段。 (C) 2015 Elsevier Ltd. 保留所有权利。
This study evaluated the consequences of damage to the parietal lobe for learning a visuomotor tracking skill. Thirty subjects with a single unilateral brain lesion (13 with and 17 without parietal damage) and 23 demographically comparable healthy subjects performed the Rotary Pursuit task. For each group, time on target increased significantly across the four learning blocks. Subjects with parietal lesions had smaller improvements on the Rotary Pursuit from the 1st to the 4th block than subjects with lesions in other brain areas and healthy comparison subjects. The improvements on task performance from the 1st to the 2nd and from the 1st to the 3rd learning blocks were similar between groups. The parietal lobe appears to play an important role in the acquisition of a new visuomotor tracking skill, in particular during a relatively late phase of learning. (C) 2015 Elsevier Ltd.
