计算障碍，或数学学习障碍，目前已知是异质性的（Wilson & Dehaene，）。虽然计算障碍的各种轮廓共存，这种数学学习障碍的一个普遍和持久的标志是难以记忆算术事实（Geary，Hoard&Hamson; Jordan&Montani; Slade & Russel）。算术事实是通过直接从记忆中检索来解决的简单算术问题。最近，德·维舍尔和诺埃尔（）在一名患有算术事实存储特定缺陷的成年人身上表现出记忆对干扰的超敏反应。根据作者的说法，算术事实有许多共同的特征。算术事实之间的这些特征的重叠可能引起干扰。因此，对干扰高度敏感的学习者在存储算术事实时可能会遇到相当大的困难。本研究旨在验证这一新的假设，对四年级儿童谁是学习乘法表。在101名被评估的儿童中，23名低算术事实学习者被选中，因为他们在算术事实流畅性（控制处理速度）方面得分较低。选择了23名对照儿童，按班级、性别和年龄进行匹配。除了全球推理的子测试外，这些参与者还被赋予乘法生产任务和低干扰和高干扰关联的记忆任务。结果表明，与具有典型算术流畅性的儿童相比，算术流畅性低的儿童在记忆中经历了对干扰的超敏反应。
Dyscalculia, or mathematics learning disorders, is currently known to be heterogeneous (Wilson & Dehaene, ). While various profiles of dyscalculia coexist, a general and persistent hallmark of this math learning disability is the difficulty in memorizing arithmetic facts (Geary, Hoard & Hamson, ; Jordan & Montani, ; Slade & Russel, ). Arithmetic facts are simple arithmetic problems that are solved by direct retrieval from memory. Recently, De Visscher and Noel () showed hypersensitivity-to-interference in memory in an adult suffering from a specific deficit of arithmetic facts storage. According to the authors, arithmetic facts share many features. The overlapping of these features between arithmetic facts may provoke interference. Consequently, learners who are hypersensitive-to-interference could have considerable difficulties in storing arithmetic facts. The present study aims at testing this new hypothesis on fourth-grade children who are learning multiplication tables. Among 101 children that were assessed, 23 low arithmetic facts learners were selected because of their low score in arithmetic facts fluency (controlling for processing speed). Twenty-three control children were selected, matched for classroom, gender, and age. In addition to a subtest of global reasoning, these participants were given a multiplication production task and a memorization task of low- and high-interference associations. The results show that children with low arithmetic fluencies experience hypersensitivity-to-interference in memory compared with children with typical arithmetic fluencies.
