眼睛在空间中从一个点到另一个点快速扫视运动，每秒数次。一般认为，视觉环境的一些心理表征在跨扫视记忆中的眼球运动中保持。我们研究的作用，在编码的信息到trans-saccadic记忆使用部分报告程序的注意。在一个注视中呈现字母阵列，然后在对新位置进行扫视后，用条形标记探测一个阵列位置的报告。准确性是高的位置，受试者已被告知要注意，但它也是高的位置附近的眼跳目标，即使受试者已被指示参加其他地方。这些结果表明，注意力决定了哪些信息被编码到跨扫视记忆中，从而在眼球运动中被记住。因为注意力自动先于眼睛到达扫视目标位置，所以扫视目标附近的信息可能被编码。结果讨论的VAM，神经认知模型的视觉注意Schneider（1995）提出的。
The eyes make rapid, saccadic movements from point to point in space several times each second. It is generally assumed that some mental representation of the visual environment is maintained across eye movements in a trans-saccadic memory. We examined the role of attention in the encoding of information into trans-saccadic memory using a partial report procedure. A letter array was presented in one fixation, then a bar marker probed report of one array position after a saccade was made to a new location. Accuracy was high for positions that subjects had been told to attend to, but it was also high for positions near the saccade target, even if subjects had been instructed to attend elsewhere. These results indicate that attention determines what information is encoded into trans-saccadic memory and hence remembered across eye movements. Because attention automatically precedes the eyes to the saccade target location, information near the saccade target is likely to be encoded. The results are discussed in terms of VAM, the neurocognitive model of visual attention proposed by Schneider (1995).
