Researchers have utilized reaching paradigms to measure infant handedness for more than a century. However, methods vary widely. Recent research has identified that the number of trials used in assessment is critical with the recommendation that at least 15 trials are necessary to reliably classify infants into handedness categories via statistical cutoffs. As a first step towards establishing best practices for the field, we identified, categorized, and synthesized findings according to trial number from studies that utilized reaching to index handedness in infants across the first two years of life using PRISMA guidelines. Database searches were conducted in PsycINFO, PubMed, and Ovid MEDLINE®. All articles published through May 2018 were included. Additional records were identified through other sources. After removing duplicates, 1,116 records were screened using the online software program Abstrackr. Of these records, 125 full-text articles were further assessed for eligibility, and 87 articles were included in the qualitative synthesis. Results revealed that the majority of papers published since 1890 (70%) do not meet the 15-trial minimum criterion for statistically reliable measurement of infant handedness. Broad themes from articles meeting the measurement criterion and implications for future research are discussed.

通过伸手可靠地测量婴儿的利手习惯:系统评价。

一个多世纪以来,研究人员一直利用伸手范式来测量婴儿的利手习惯。然而,方法差异很大。最近的研究发现,评估中使用的试验数量至关重要,建议至少需要 15 次试验才能通过统计截止值将婴儿可靠地分类为利手类别。作为建立该领域最佳实践的第一步,我们根据 PRISMA 指南利用伸手能力来衡量婴儿生命前两年的利手习惯的研究的试验编号,对结果进行了识别、分类和综合。在 PsycINFO、PubMed 和 Ovid MEDLINE ®中进行数据库检索。截至 2018 年 5 月发表的所有文章均包含在内。通过其他来源确定了更多记录。删除重复项后,使用在线软件程序 Abstrackr 筛选了 1,116 条记录。在这些记录中,125 篇全文文章的资格得到了进一步评估,87 篇文章被纳入定性综合。结果显示,自 1890 年以来发表的大多数论文 (70%) 都不符合婴儿利手习惯统计可靠测量的 15 次试验最低标准。讨论了满足测量标准的文章的广泛主题以及对未来研究的影响。
