Evidence for the hypothesis that the appearance of visually presented words is stored in "literal copy" form is critically evaluated and shown to be inconclusive. An experiment in which students were required to retain information about zero, one, or two visual properties of words is reported. A strong version of the literal-copy hypothesis predicts that retention of both case and color should be equally good under instructions to remember one of these attributes and instructions to remember both. However, the results were inconsistent with predictions from this hypothesis. A model that assumes that each visual attribute is stored independently in abstract propositional form provided a good quantitative fit to the data.
关于视觉呈现的单词外观以“文字副本”形式存储这一假设的证据受到了批判性评估，结果显示尚无定论。本文报告了一项实验，要求学生记住单词的零个、一个或两个视觉属性。文字副本假设的一个强版本预测，在记住这些属性之一的指令和记住两者的指令下，大小写和颜色的保留效果应该同样好。然而，结果与该假设的预测不一致。一个假设每个视觉属性以抽象命题形式独立存储的模型对数据提供了良好的定量拟合。
