许多视觉搜索理论提供了一般原则，旨在适用于搜索由任何刺激属性定义的目标。考虑不同的视觉子系统的特定属性的重要性证明通过检查搜索运动方向的连接。在混合移动和静止刺激的显示中，在移动刺激中搜索显著倾斜目标（45度与垂直）比静止刺激更容易。如果需要更精细的方向区分（9度与垂直）。反之亦然;在固定的区域中搜索更容易。这是根据专门处理移动或静止刺激的视觉子系统的已知特性得出的。它不是由视觉搜索的一般理论预测的，如引导搜索或相似性理论，也不是由完形分组的原则。
Many theories of visual search offer general principles intended to apply to search for targets defined by any stimulus attribute. The importance of considering specific properties of different visual subsystems is demonstrated by examining search for movement-orientation conjunctions. In displays of intermingled moving and stationary stimuli, search for a salient tilted target (45-degrees vs. vertical) is easier among moving than stationary stimuli. If a finer orientation distinction is required (9-degrees vs. vertical). the reverse is true; search is easier among the stationary. This follows from the known properties of visual subsystems specialized for processing moving or stationary stimuli. It is not predicted by general theories of visual search such as guided search or similarity theory, nor by principles of Gestalt grouping.
