Endogenous attention can be allocated in parallel to at least two saccade target locations of a planned sequence, but attentional resources are larger in the location of the first than the second saccade. The meridian effect that is observed in endogenous attention can be explained by eye programming, but it is not known how eye-movement preparation and eye programming can together affect endogenous attention during sequential saccades. We used a double-task paradigm to investigate this issue. In two experiments, we confirmed the relation between the preparation of sequential saccades and attentional selection and also showed that eye programming could eliminate deterioration of attentional resources in the second saccade location. The finding of the meridian effect in both the saccadic task and the target discrimination task additionally indicates the important role of eye programming in endogenous attention. The results were discussed in terms of the Premotor Theory of Attention.

扫视序列的准备和眼睛编程会影响内源性秘密注意。

可以将内生注意力并行分配给计划序列的至少两个扫视目标位置，但第一个扫视的位置的注意力资源要大于第二个扫视的位置。内在注意中观察到的子午线效应可以通过眼睛编程来解释，但尚不清楚眼动准备和眼睛编程如何在顺序扫视期间共同影响内生注意。我们使用双重任务范例来研究此问题。在两个实验中，我们确认了连续扫视的准备与注意选择之间的关系，并且还表明，眼睛编程可以消除第二扫视位置中注意资源的退化。在子午任务和目标辨别任务中都发现子午线效应，这进一步表明了眼睛编程在内源性注意力中的重要作用。根据前运动注意力理论对结果进行了讨论。
