这项研究得到了荷兰先锋基金的支持。视觉注意力可以分散在多个物体或位置上。然而，没有一个单一的理论框架可以解释注意力分散的影响。为了建立这样一个模型，我们在这里操纵了注意力被分割的视觉处理阶段，同时探讨了在两个维度上划分注意力的成本。我们表明，分散注意力会产生可分离的时间和精度成本，这取决于注意力是在监测期间还是在访问期间被分散。在监测期间分散注意力，导致随着监测更多地点，进入被监测地点的时间逐渐延迟，以及一次性的精确费用。当在访问过程中分散注意力时，一个被访问位置的时间成本系统地低于另一个被访问位置，这表明在访问过程中分散注意力实际上涉及到未分散注意力的快速顺序分配。我们提出了一个模型，在这个模型中，分散注意力被理解为同时并行准备和随后连续执行多个集中注意力的转移。这种解释有可能汇集来自分散注意和扫视准备文献的不同发现，并提供一个框架，在其中整合广泛的分散注意方法。
This research was supported by a Pioneer grant from the Netherlands Visual attention can be divided over multiple objects or locations. However, there is no single theoretical framework within which the effects of dividing attention can be interpreted. In order to develop such a model, here we manipulated the stage of visual processing at which attention was divided, while simultaneously probing the costs of dividing attention on two dimensions. We show that dividing attention incurs dissociable time and precision costs, which depend on whether attention is divided duringmonitoring or duringaccess. Dividing attention during monitoring resulted in progressively delayed access to attended locations as additional locations were monitored, as well as a one-off precision cost. When dividing attention during access, time costs were systematically lower at one of the accessed locations than at the other, indicating that divided attention during access, in fact, involves rapid sequential allocation of undivided attention. We propose a model in whichdivided attention is understood as the simultaneous parallel preparation and subsequent sequential execution of multiple shifts ofundivided attention. This interpretation has the potential to bring together diverse findings from both the divided-attention and saccade preparation literature and provides a framework within which to integrate the broad spectrum of divided-attention methodologies.
