本研究调查了两个问题：第一个问题是研究非流利阅读者的单词识别和理解的准确性和延迟之间的关系；第二个问题是研究这些读者在单词识别中是否使用了组成字母处理或整体处理。对单个单词进行了单词识别速度和准确率的测试。在有意义的语境中，对同样的单词进行文字理解。感知单位通过单词识别潜伏期与单词长度的关系来衡量。如果学生使用组件处理，延迟会随着单词长度的增加而增加，但如果使用整体处理，延迟不会随着单词长度的增加而增加。本研究结果表明，对一年级和二年级词汇的理解，准确率和潜伏期均显著相关，且潜伏期对一年级词汇的理解得分影响更大。关于感知单位，总体而言，所有受试者都有成分字母处理的证据，高度准确的读者表现出更全面的处理倾向。
Two issues were investigated: the first examined the relationships among accuracy and latency of word recognition and comprehension by non-fluent readers, and the second examined whether component letter or holistic processing was used in word recognition by these same readers. Speed and accuracy of word recognition were measured on individual words. Literal comprehension was measured for the same words presented in meaningful context. The unit of perception was measured by the relationship between latency of word recognition and word length. If students were using component processing, latency would increase with word length, but if holistic processing were used, there would be no increase in latency with length. Results of this study indicated that accuracy and latency were each significantly related to comprehension for both first- and second-grade words, with evidence for latency influencing comprehension scores to a greater extent on the first-grade words. With regard to the unit of perception, in general there was evidence of component letter processing for all subjects with the highly accurate readers showing a tendency towards more holistic processing.
