在一系列的5个实验中，使用双任务范式考察了眼跳序列执行前的注意力分配。在主要任务中，参与者被要求执行一系列2次内源性眼跳。第二项任务是强制选择字母辨认任务。在眼跳序列的编程过程中，字母被短暂地呈现在眼跳球门和非眼跳位置。结果表明，在任何一个扫视目标上出现的字母比在任何一个无眼跳位置出现的字母表现更好。结果支持一个空间模型，该模型假设在执行扫视序列之前，注意力被并行地分配到所有扫视目标。
In a series of 5 experiments, the allocation of attention prior to the execution of saccade sequences was examined by using a dual-task paradigm. In the primary task, participants were required to execute a sequence of 2 endogenous saccades. The secondary task was a forced-choice letter identification task. During the programming of the saccade sequences, letters were briefly presented at the saccade goals and at no-saccade locations. The results showed that performance Was better for letters presented at any of the saccade goals than for letters presented at any of the no-saccade locations. The results support a spatial model that assumes that prior to the execution of a saccade sequence, attention is allocated in parallel to all saccade goals.
