本文介绍了一例患者J.G.在左顶骨肿瘤手术后出现严重的计算问题（以及失写症、手指失认症、左右定向障碍和失用症）。虽然患者完全失去了算术的概念知识，但她保留了部分记忆的事实知识（乘法和一些加减法）。研究表明，在不了解所执行的操作的情况下，算术事实可以在表面上表示。该研究完成了计算中涉及的两种知识（记忆事实和概念知识）的有效双重解离。
The paper presents a single-case study of patient J.G. showing severe calculation problems (and also agraphia, finger agnosia, right-left disorientation and apraxia) after the surgery of a left parietal tumor. Although the patient completely lost conceptual knowledge of arithmetic, she preserved part of memorised fact knowledge (multiplications and some additions and subtractions). The study indicates that arithmetic facts can be represented at a superficial level without understanding of the operation performed. The study completes a valid double dissociation between two types of knowledge involved in calculation (memorised facts and conceptual knowledge).
