通过两个实验探讨了旁视字母与空间信息在阅读眼动引导中的关系。视读者的注视情况而定，注视右侧可获得的旁视信息的类型由以下几种情况而变化：（a）仅空间信息，（B）空间信息与在某个延迟添加的字母信息，或（c）字母和空间信息同时。此外，发病的相关旁的信息延迟0和250毫秒之间的固定。处理这两种类型的信息（字母或空格）的时间过程不同，它们对眼动记录的影响的性质也不同。尽管字母和空间信息都影响眼跳长度和单词中的初始着陆位置，但只有字母信息对注视持续时间有影响。此外，固定持续时间的影响，只有在固定的前50毫秒内进入的信息，而眼跳长度的影响，在固定过程中的任何时间到达的信息。结果与眼球运动控制模型一致，其中2个独立的过程串联操作以确定在阅读期间何时和何处移动眼球。
The relation between parafoveal letter and space information in eye movement guidance during reading was investigated in 2 experiments. Contingent upon the reader's fixation, the type of parafoveal information available to the right of fixation was varied by (a) space information only, (b) space information with letter information added at some delay, or (c) letter and space information simultaneously. In addition, the onset of the relevant parafoveal information was delayed between 0 and 250 ms into the fixation. The time course of processing the 2 types of information (letters or spaces) differed, as did the nature of their impact on the eye movement record. Although both letter and space information influenced saccade length and initial landing positions within words, only letter information had an effect on fixation duration. In addition, fixation duration was affected only by information entering within the first 50 ms of the fixation, whereas saccade length was affected by information arriving at any time during the fixation. The results are consistent with a model of eye movement control in which 2 independent processes are operating in tandem to determine when and where to move the eyes during reading.
