两个实验调查了副中央凹中呈现的单词的性质对同时接受中心凹检查的单词的处理时间的影响程度。在实验1中，受试者在一个固定的点观看一组五个字母的单词，这些单词在中央凹旁视觉中的长度、词频以及其前三个字母的类型和符号出现频率都不同。结果表明，靶点出现的频率及其首字母的打字频率影响中心凹注视时间。在实验2中，受试者在对实验物品进行初始注视之前进行一系列的眼跳。在这种情况下，注视时间总体上较短。副中凹单词的词汇特征对中心凹加工没有影响，但其首字母的长度和打字频率对中心凹加工有较大影响。这种形式的副中央凹对中央凹的效应与注意力按顺序分配到连续单词的阅读模式不相容。这些数据与以下命题更一致：中央凹和副中央凹的加工是平行进行的，加工过程分布在一个比一个字更大的区域。辅助分析显示，任何被操纵的变量对眼跳程度的影响都很小。
Two experiments investigated the degree to which properties of a word presented in the parafovea influenced the time to process a word undergoing concurrent foveal inspection. In Experiment 1, subjects viewed a set of five-letter words at a fixed point, with words in parafoveal vision varying in length, word frequency, and both the type and token frequency of occurrence of their initial three letters. The results showed that the frequency of the target and the type frequency of its initial letters influenced foveal fixation time. In Experiment 2, subjects executed a sequence of saccades before initial fixation on the experimental items. Under these circumstances, fixation time was shorter overall. Lexical properties of parafoveal words had no effect on foveal processing, but the length and the type frequency of their initial letters exerted a strong influence. Parafoveal-on-foveal effects of this form are incompatible with models of reading in which attention is allocated sequentially to successive words. The data are more consistent with the proposition that foveal and parafoveal processing occurs in parallel, with processing distributed over a region larger than a single word. Subsidiary analyses showed little influence of any of the manipulated variables on saccade extent.
