两个实验考察了读者使用从旁脑室获得的字长信息进行单词识别的情况。这两个实验都操纵了副正面预览的目标单词的长度(组成字符的数量)，以便准确或不准确地指定它。在实验1中，预习也揭示或否定了有用的拼写信息。在实验2中，副中央凹目标是高频词或低频词。利用眼动条件显示变化来显示目标物注视时的完整。对目标观看时长的检验表明，实验一中字长预览和拼写预览的全加性效应，精确长和拼写预览条件下的观看时长较短。实验2显示词长和词频的完全加性效应，在精确词长和高频条件下，目标观看时间较短。总之，这些结果表明，在阅读中，不同的功能子系统控制着视旁可见的空间和语言信息的使用。视旁可见的空间信息似乎被用于两种不同的非语言计算：视觉对象选择和扫视指定。
Two experiments examined readers' use of parafoveally obtained word length information for word recognition. Both experiments manipulated the length (number of constituent characters) of a parafoveally previewed target word so that it was either accurately or inaccurately specified. In Experiment 1, previews also either revealed or denied useful orthographic information. In Experiment 2, parafoveal targets were either high- or low-frequency words. Eye movement contingent display changes were used to show the intact target upon its fixation. Examination of target viewing duration showed completely additive effects of word length previews and of ortho-graphic previews in Experiment 1, viewing duration being shorter in the accurate-length and the orthographic preview conditions. Experiment 2 showed completely additive effects of word length and word frequency, target viewing being shorter in the accurate-length and the high-frequency conditions. Together these results indicate that functionally distinct subsystems control the use of parafoveally visible spatial and linguistic information in reading. Parafoveally visible spatial information appears to be used for two distinct extralinguistic computations: visual object selection and saccade specification.
