该研究通过经典的不可见边界范式和一种新颖的旁视预览操作（即，视觉退化）。眼动研究了5个字母的目标词与约束（即，高度信息化）的首字母或类似约束的最后字母。视觉退化管理的所有，没有，最初的，或最后2个字母的旁视预览的目标词。重要的是，旁视预览的操作并没有干扰中央凹的处理。因此，我们有一个适当的基线，我们可以把我们的主要发现，这是如下：首先，有效的（即，未降级的）目标单词的最后字母的预览导致与基线条件相比更短的注视时间（即，所有字母的退化）。第二，最后一封信的预览益处与预览最初一封信的益处相当。第三，然而，与不受约束的初始字母序列的预览相比，受约束的初始字母序列的预览产生了更大的预览益处。后一项发现表明，预处理约束初始字母是特别有利于中央凹字识别。
The study investigated parafoveal preprocessing by the means of the classical invisible boundary paradigm and a novel manipulation of the parafoveal previews (i.e., visual degradation). Eye movements were investigated on 5-letter target words with constraining (i.e., highly informative) initial letters or similarly constraining final letters. Visual degradation was administered to all, no, the initial, or the final 2 letters of the parafoveal preview of the target words. Critically, the manipulation of the parafoveal previews did not interfere with foveal processing. Thus, we had a proper baseline to which we could relate our main findings, which were as follows: First, the valid (i.e., nondegraded) preview of the target words' final letters led to shorter fixation times compared to the baseline condition (i.e., the degradation of all letters). Second, this preview benefit for the final letters was comparable to the benefit of previewing the initial letters. Third, the preview of a constraining initial letter sequence, however, yielded a larger preview benefit than the preview of an unconstraining initial letter sequence. The latter finding indicates that preprocessing constraining initial letters is particularly conducive to foveal word recognition.
