Dataset 2 for Learning number notations – Comparison of a sign-value and place-value system

Data analysis files associated with the paper "Learning number notations – Comparison of a sign-value and place-value system".Includes the original JASP files, HTML exports of the results presented in each JASP file, the csv file to run all analyses and a ReadMe document which describes and explains all varaibles used in the csv file.Article abstractAlthough numbers are universal, there are great differences between languages and cultures in terms of how they are represented. Numerical notation can influence number processing. Two well-known types of notational systems are sign-value, such as the Roman numeral system, and place-value systems, such as the Indo-Arabic numeral system. What is involved in learning each system? Here we report a study that investigated adults’ abilities to implicitly learn an artificially created sign-value or place-value system. We asked if they could perform symbolic comparison and ordering tasks using the novel symbol system. We found adults could learn the ordinal meaning of symbols within either system and were able to extend the system to symbols not encountered during training. There was a relative advantage of the sign-value system over the place-value system for expressions encountered during the training, but also for expressions that had not previously been encountered. These results shed light on how easily the structure of place-value and sign-value systems can be learned.

本数据集关联论文《学习数字记号系统——符号值与位值计数体系的对比》（Learning number notations – Comparison of a sign-value and place-value system），包含原始JASP分析文件、各JASP文件结果的HTML导出文件、可复现所有分析的CSV文件，以及一份用于说明并解释CSV文件中所有变量的ReadMe文档。

【论文摘要】数字虽具有通用性，但不同语言与文化在数字表征方式上存在显著差异。数字记号系统会对数字加工过程产生影响。两类广为人知的记号体系分别为符号值系统（sign-value system），如罗马数字体系；以及位值系统（place-value system），如印度-阿拉伯数字体系。学习两类体系分别涉及哪些认知过程？本研究探讨了成年人内隐学习人工构建的符号值或位值系统的能力。实验要求被试使用全新的符号体系完成符号比较与排序任务。结果显示，成年人可习得两类体系中符号的序数含义，并能将所学体系推广至训练阶段未接触过的符号。在训练阶段接触过的表达式以及此前未遇过的表达式上，符号值系统均展现出相对于位值系统的相对优势。本研究结果有助于深入理解位值与符号值系统的结构学习难度。
