Selected ICAR data from the SAPA-Project: Development and initial validation of a public-domain measure

These data were collected during the initial evaluation of the International Cognitive Ability Resource (ICAR) project. ICAR is an international collaborative effort to develop open-source public-domain tools for cognitive ability assessment, including tools that can be administered in non-proctored environments (e.g., online administration) and those which are based on automatic item generation algorithms. These data provide initial validation of the first four ICAR item types as reported in Condon & Revelle, 2014. The 4 item types contain a total of 60 items: 9 Letter and Number Series items, 11 Matrix Reasoning items, 16 Verbal Reasoning items and 24 Three-dimensional Rotation items. Approximately 97,000 individuals were administered random subsets of these 60 items using the Synthetic Aperture Personality Assessment method between August 18, 2010 and May 20, 2013. The data are available in rdata and csv formats and are accompanied by documentation stored as a text file. Re-use potential includes a wide range of structural and item-level analyses.本数据集采集自国际认知能力资源（International Cognitive Ability Resource, ICAR）项目的初始评估阶段。ICAR是一项国际性合作项目，旨在开发用于认知能力评估的开源公共领域工具，涵盖可在非监考环境下施测的工具（如线上施测）以及基于自动化项目生成算法的工具。本数据集首次验证了ICAR的前四类项目题型，相关发现已发表于Condon与Revelle 2014年的研究中。该四类项目题型共计包含60道测验题目：9道字母与数字序列题、11道矩阵推理题、16道言语推理题与24道三维旋转题。2010年8月18日至2013年5月20日期间，约97000名受试者通过合成孔径人格评估（Synthetic Aperture Personality Assessment）法完成了该60道题目的随机子集作答。本数据集提供rdata与csv两种格式的存储文件，并附带以纯文本格式保存的说明文档。该数据集具备广泛的复用潜力，可支持多类结构层面与项目层面的分析研究。
