当不受约束的受试者轻拍或只看着附近的目标时，眼睛和头部的运动被记录下来。在这两项任务中，扫描模式是相同的：受试者在敲击目标之前先看一眼；视觉搜索的速度和凝视转移的准确性相似，然而，看起来需要更长的时间，而且与敲击不同，练习几乎没有什么好处。当内存负载减少时，看起来比敲击速度更快：在敲击过程中内存更高效。结论：只看时的眼动不同于敲击时的眼动，视觉搜索作为一个独立的过程，整合到两个任务中：当记忆负荷较大时，它可以用来提高性能。
Eye and head movements were recorded as unrestrained subjects tapped or only looked at nearby targets. Scanning patterns were the same in both tasks: subjects looked at each target before tapping it; visual search had similar speeds and gaze-shift accuracies, Looking, however, took longer and, unlike tapping, benefitted little from practice. Looking speeded up more than tapping when memory load was reduced: memory was more efficient during tapping. Conclusion: eye movements made when only looking are different from those made when tapping, Visual search functions as a separate process, incorporated into both tasks: it can be used to improve performance when memory load is heavy.
