An optimal viewing position (OVP) for word recognition has been proposed by several authors. The location of this position would be located at the center of the word or just left of it. Several hypotheses ranging from perceptual to hemispheric factors have been proposed to explain this phenomenon. In the experiment presented here, the effect of the nature of the stimulus was tested: word, pseudo-word, or nonword on the existence and location of this position. Little research has investigated this issue. Five-letter words, pseudo-words, and non-words were presented, with the subject fixating initially on one of the five possible letter positions. The number of letters correctly identified and reading performance were recorded for each stimulus. Results show that an initial fixation on the third letter entails better letter identification for all kinds of stimuli. However, in terms of reading, only word reading benefit from a fixation on the third letter. These results are discussed in relation to the different hypotheses of OVP in reading. These are (1) hemispheric specialization, (2) reading habits, and (3) lexical constraints.
几位作者提出了单词识别的最佳注视位置（OVP）。该位置位于单词的中心或其左侧。人们提出了从感知因素到半球因素等几种假设来解释这一现象。在本文所呈现的实验中，测试了刺激性质（单词、伪词或非词）对该位置的存在及位置的影响。很少有研究探讨过这个问题。呈现了五个字母的单词、伪词和非词，让受试者最初注视五个可能字母位置中的一个。记录每个刺激下正确识别的字母数量和阅读表现。结果表明，最初注视第三个字母能使各类刺激的字母识别效果更好。然而，在阅读方面，只有单词阅读从注视第三个字母中受益。结合阅读中OVP的不同假设对这些结果进行了讨论。这些假设包括：（1）半球特化，（2）阅读习惯，（3）词汇限制。
