将注意力分散在多个单词上有时会导致误识别，即字母显然会在单词之间移动。以前的研究发现，字母迁移保留了单词内的字母位置，这被解释为支持特定位置的字母编码。为了研究这个问题，作者使用了像Step和Soap这样的单词对，在这些单词中，一个单词中的一个字母可以迁移到另一个单词中的相邻字母，从而形成一个虚幻的单词(STOP)。三个实验表明，同位置字母迁移和相邻位置字母迁移都可以发生，也可以发生跨越两个字母位置的迁移。这些结果反对在许多阅读计算模型中使用的位置特定字母编码方案，并且它们支持基于相对字母位置而不是绝对字母位置的编码方案。
Dividing attention across multiple words occasionally results in misidentifications whereby letters apparently migrate between words. Previous studies have found that letter migrations preserve within-word letter position, which has been interpreted as support for position-specific letter coding. To investigate this issue, the authors used word pairs like STEP and SOAP, in which a letter in 1 word could migrate to an adjacent letter in another word to form an illusory word (STOP). Three experiments show that both same-position and adjacent-position letter migrations can occur, as well as migrations that cross 2 letter positions. These results argue against position-specific letter coding schemes used in many computational models of reading, and they provide support for coding schemes based on relative rather than absolute letter position.
