In English and some other languages, spelling problems that arise at a phonological level can sometimes be solved through consideration of morphology. For example, children could infer that tuned should contain an n and that fighting should contain a t because their stems include these letters. Children could thus avoid misspellings that might otherwise occur, such as "tud" and "fiding." We used a spelling-level match design to examine the extent to which children with dyslexia and younger typical children use morphology in this way. Both groups of children benefited from morphology to some extent, but not as much as they could have given their knowledge of the stems. Our results suggest that the spellings produced by older children with dyslexia are similar to those of younger normal children in their morphological characteristics, as well as in other ways.
在英语和其他一些语言中，有时可以通过考虑词形变化来解决语音层面出现的拼写问题。例如，孩子们可以推断出“tuned”应该包含一个“n”，“fighting”应该包含一个“t”，因为它们的词干包含这些字母。这样孩子们就可以避免可能出现的拼写错误，比如“tud”和“fiding”。我们采用了一种拼写水平匹配设计，以研究患有诵读困难症的儿童和年幼的正常儿童在多大程度上以这种方式运用词形变化。两组儿童在一定程度上都从词形变化中受益，但受益程度不如他们凭借对词干的了解本应达到的程度。我们的研究结果表明，患有诵读困难症的大龄儿童所产生的拼写在词形特征以及其他方面与年幼正常儿童的拼写相似。
