摘　　要：Müller提出维度权值概念(Dimensional weighting)来解释注意选择,他认为在视觉搜索过程中,来自自上而下和自下而上的信息会根据任务的需求联合起来,对注意进行动态性调整。维度权值理论对选择注意的解释得到了行为、脑成像及脑损伤研究的支持,目前它已经成为解释两种控制加工关系的重要理论。The account dimension-weighting of visual selection was developed by Miiller suggests that during visual search, both top-down information and bottom-up information combine as required by the task to dynamically mediate attention. The ＇dimension- weighting＇ account of visual selection has obtained evidence from behavior, fMRI and brain lesions studies. At present, it has become one of the most important theories to explain the relation between two types of control.
