虽然在传统的注意研究中，视觉空间注意的焦点被认为是不可分割的，但在过去的15年中，许多研究都声称相反。这些研究表明，人类可以直接他们的注意力同时多个不连续的区域的视野，只要指令。空间注意力可以很容易地被分割，这一概念在当前的注意力神经认知模型中是违反直觉的。我们检查了关于分散注意力的研究，针对4个方法标准，这些标准应该得到满足，以便令人信服地证明分散注意力，我们发现目前的文献中没有通过这项测试的研究。在当前注意力理论的基础上，我们认为，分开注意力可能不容易由天真的人类观察者实现，相反，这是一种只能通过训练才能获得的技能。
Although in traditional attention research the focus of visual spatial attention has been considered as indivisible, many studies in the last 15 years have claimed the contrary. These studies suggest that humans can direct their attention simultaneously to multiple noncontiguous regions of the visual field upon mere instruction. The notion that spatial attention can easily be split is counterintuitive in the light of current neurocognitive models of attention. We examined studies on divided attention against 4 methodological criteria that should be satisfied in order to convincingly demonstrate divided attention, and we found no studies in the current literature that pass this test. On the basis of current theories of attention, we argue that dividing attention may not be easily achievable by naive human observers and that, instead, it is a skill that may be acquired only through training.
