Visual search performance (with sets chosen to elicit both serial and parallel search patterns) under two conditions that precluded saccades was compared to the typical situation in which visual inspection of the array is possible. In one condition, the display duration was so brief that any saccades that were executed would be too late to bring the targeted portion of the array into the fovea. In the other, the display remained present until the subject's response, but eye position was monitored and trials with shifts in fixation were excluded from analysis. The latter condition produced search latencies that were nearly identical to those with free inspection. Brief exposure, in contrast, did not produce the pattern typical of serial search, presumably because of strategies induced to deal with the rapid decay of the visual array. It is concluded that saccadic eye movements play little role in the patterns of performance used to infer serial and parallel search, and that brief exposure is not a satisfactory technique for exploring the role of saccadic eye movements in visual search.
在两种排除扫视的条件下，对视觉搜索性能（通过选择能引发串行和平行搜索模式的集合）进行了比较，与可对阵列进行视觉检查的典型情况进行对比。在一种条件下，显示持续时间非常短暂，以至于任何执行的扫视都太晚而无法将阵列的目标部分带入中央凹。在另一种条件下，显示一直呈现直到受试者做出反应，但会监测眼睛位置，并且排除注视点发生移动的试验进行分析。后一种条件产生的搜索潜伏期与自由检查时的潜伏期几乎相同。相比之下，短暂暴露并没有产生串行搜索的典型模式，大概是因为为应对视觉阵列的快速衰减而引发的策略。得出的结论是，眼跳运动在用于推断串行和平行搜索的性能模式中作用不大，并且短暂暴露不是探索眼跳运动在视觉搜索中作用的令人满意的技术。
