Recent studies on handwriting production and neuropsychological data have suggested that orthographic representations are multilevel structures that encode information on letter identity and order, but also on intermediate-grained processing units such as syllables and morphemes. This study on handwriting production examined whether orthographic representations also include a graphemic-processing level. French adults wrote words containing an embedded one-, two-, or three-letter grapheme (e.g., a in clavier, ai in prairie, ain in plainte) on a digitizer. The results for letter duration revealed that the timing of movement processing depends on grapheme length (e.g., the duration of a for one-letter graphemes was shorter than that for two-letter graphemes, which, in turn, was shorter than that for three-letter graphemes). Two- and three-letter graphemes start to be processed before we start to write them. The results therefore revealed that orthographic representations also encode information on grapheme complexity.
最近关于笔迹生成和神经心理学数据的研究表明，拼写字元的表示是多层次的结构，编码有关字母身份和顺序的信息，但也编码有关中间粒度处理单元的信息，如音节和语素。这项关于笔迹生成的研究检验了拼写字元的表示是否还包括字形处理层次。法国成年人在数位板上书写包含嵌入的一个、两个或三个字母的字形的单词（例如，clavier 中的 a、prairie 中的 ai、plainte 中的 ain）。字母持续时间的结果表明，运动处理的时间取决于字形长度（例如，一个字母字形的 a 的持续时间比两个字母字形的 a 短，而两个字母字形的 a 又比三个字母字形的 a 短）。两个和三个字母的字形在我们开始书写之前就开始被处理。因此，结果表明，拼写字元的表示还编码有关字形复杂性的信息。
