有文献认为，空间precuing的注意与周边和中央线索可能是由不同的机制介导的。为了研究这个问题，我们重新分析了之前两篇论文中的数据，以研究用以下两种方式来预测目标位置的完整时间过程：（1）可能引起注意的反射性外围线索，或（2）可能需要注意力自愿定向的中央象征性线索。这种分析导致了在另一个实验中测试的预测。本实验的主要结果是，周边线索产生的歧视性能在100毫秒内的最大影响，而中央线索需要约300毫秒，以实现最大的效果。结合以前的研究结果，目前的证据表明，两个线索条件之间的时间差异表明，一个以上的过程是参与注意的空间precuing。
There are suggestions in the literature that spatial precuing of attention with peripheral and central cues may be mediated by different mechanisms. To investigate this issue, data from two previous papers were reanalysed to investigate the complete time course of precuing target location with either: (1) a peripheral cue that may draw attention reflexively, or (2) a central, symbolic cue that may require attention to be directed voluntarily. This analysis led to predictions that were tested in another experiment. The main result of this experiment was that a peripheral cue produced its largest effects on discrimination performance within 100 msec, whereas a central cue required approximately 300 msec to achieve maximum effects. In conjunction with previous findings, the present evidence for time differences between the two cuing conditions suggests that more than one process is involved in the spatial precuing of attention.
