This paper reports a patient with a selective difficulty in spelling words and pseudowords with geminate (double) consonants. In all writing tasks, deletions of a geminate consonant occurred ten times more often than deletions of a consonant in a non-geminate cluster. In addition, the probability of substituting both geminate consonants was indistinguishable from the probability of substituting one consonant in a non-geminate cluster; and, the probability of substituting only one geminate consonant was close to zero, and significantly lower than the probability of substituting one consonant in a non-geminate cluster. This pattern of performance is consistent with the hypothesis that grapheme quantity and identity are separately represented in orthographic representations. The fact that these errors occurred in the absence of a significant number of geminate transpositions is interpreted as support for the hypothesis that letter gemination is specified by a "doubling feature."
本文报告了一名患者，该患者在拼写包含双辅音的单词和假词时存在选择性困难。在所有书写任务中，双辅音的删除频率比非双辅音组合中辅音的删除频率高出十倍。此外，替换两个双辅音的概率与替换非双辅音组合中一个辅音的概率没有区别；而且，仅替换一个双辅音的概率接近于零，且显著低于替换非双辅音组合中一个辅音的概率。这种表现模式与以下假设一致，即字形数量和特征在正字法表征中是分别呈现的。这些错误在没有大量双辅音换位的情况下出现，这一事实被解释为支持字母双写由“重复特征”指定这一假设的证据。
