ABSTRACT

Subject handedness is an important parameter to be evaluated and accounted for in neuroscience studies dealing with laterality. The aim of this study was to survey for the details of how researchers administered the Edinburgh handedness inventory (EHI) to assess subject handedness. Web of Science and PubMed databases was searched on 3 August 2021 to identify functional magnetic resonance imaging (fMRI) articles published since 2013 using the EHI or citing Oldfield, the original paper that introduced the EHI. Articles not actually using the EHI and/or its variants were excluded. Two reviewers performed the screening independently and disagreements were solved by mutual consensus. Most of the 406 studies using the EHI did not report details regarding the number of items (94.1%), identity of items (96.1%), response format (97.0%), and cutoff score for right-handedness (87.2%). Items were found dropped or replaced, with response format and cutoff score changed without citing references that justified the modifications. A clearer reporting of the details of the EHI as an assessment tool for determining subject handedness should be encouraged.

摘要

受试者的惯用手是在处理偏侧性的神经科学研究中要评估和考虑的重要参数。本研究的目的是调查研究人员如何管理爱丁堡惯用手（EHI）以评估受试者惯用手的细节。2021 年 8 月 3 日对 Web of Science 和 PubMed 数据库进行了搜索，以识别自 2013 年以来使用 EHI 发表的功能性磁共振成像 (fMRI) 文章，或引用了介绍 EHI 的原始论文 Oldfield。不实际使用 EHI 和/或其变体的文章被排除在外。两名审稿人独立进行筛选，分歧通过共同协商解决。使用 EHI 的 406 项研究中的大多数没有报告有关项目数量 (94.1%)、项目标识 (96.1%)、响应格式 (97.0%)、和右撇子的截止分数（87.2％）。发现项目被删除或替换，响应格式和截止分数发生了变化，而没有引用证明修改合理的参考资料。应鼓励更清晰地报告 EHI 的详细信息，作为确定受试者惯用手的评估工具。
