Apparent ambiguities in Levy and Reid's writing posture criteria and dissimilar criteria used by other investigators are discussed. Classification of inverted writing postures by a diagram which, as Levy and Reid indicated in 1976, depicts typical writing positions is questioned because their 1978 paper suggests that these diagrammed positions were only an intermediary stage in the classification of some inverters. Results of studies using dissimilar criteria for writing posture appear to be difficult to compare because subjects who may differ in cerebral organization might be placed in the same category. Some of these studies introduced another possible source of confounding because different tasks were used to test lateralization of function. Since different tasks seem to study distinctive facets of language, lateralization of one function in sinistrals, thought to be less lateralized than dextrals, does not predict lateralization of any other function. These considerations suggest that an adequate test of Levy and Reid's ideas concerning the relationship among handedness, hand posture during writing, sex, and cerebral organization requires the development of a standard set of valid criteria for writing posture.
讨论了利维（Levy）和里德（Reid）书写姿势标准中明显的模糊之处以及其他研究者使用的不同标准。正如利维和里德在1976年指出的那样，用一幅描绘典型书写姿势的图表对倒向书写姿势进行分类受到质疑，因为他们1978年的论文表明，这些图表所示的姿势只是一些倒向书写者分类中的一个中间阶段。由于可能在大脑组织上存在差异的受试者可能被归为同一类别，因此使用不同标准进行书写姿势研究的结果似乎难以比较。其中一些研究引入了另一个可能造成混淆的因素，因为使用了不同的任务来测试功能的偏侧化。由于不同的任务似乎研究语言的不同方面，左利手（被认为比右利手的功能偏侧化程度低）中一种功能的偏侧化并不能预测任何其他功能的偏侧化。这些考虑表明，要充分检验利维和里德关于利手、书写时的手部姿势、性别和大脑组织之间关系的观点，需要制定一套标准的有效书写姿势标准。
