三个实验提供的证据表明，2个机制，1个自动和1个控制，本地和全球形式的处理效率产生变化。如果目标出现在与先前试验中的目标相同的水平（全局或局部），则可以更快地识别目标。M. R.羔羊肉，B。伦敦，H。M. Pond和K. A. Whitt（1998）提供的证据表明，水平重复的有益效果是由于一个不受自愿控制的自动过程。在目前的实验中，审前提示告知参与者即将到来的目标的水平。有效的线索有利于性能，而无效的线索回家性能相对于noninformative中性线索。即使当线索和它所发出的信号水平之间的关系是任意的时，情况也是如此，这表明线索引发了注意力的自愿转移。然而，与水平重复相关的好处不受线索的影响。这些数据表明，水平重复的好处来自于一个不受自愿控制的过程。
Three experiments provide evidence that 2 mechanisms, 1 automatic and 1 controlled, produce variations in the efficiency with which local and global forms are processed. Targets are identified faster if they appear at the same level (global or local) as the target on the previous trial. M. R. Lamb, B. London, H. M. Pond, and K. A. Whitt (1998) provided evidence that the beneficial effect of level repetition is due to an automatic process that is outside voluntary control. In the present experiments, pretrial cues informed participants as to the level of the upcoming target. Valid cues benefited performance, whereas invalid cues homed performance relative to noninformative neutral cues. This was so even when the relation between the cue and the level it signaled was arbitrary, indicating that the cues initiated voluntary shifts of attention. The benefit associated with level repetition, however, was unaffected by the cues. These data suggest that the benefit of level repetition results from a process that is not subject to voluntary control.
