The rod and frame test (RFT), a measure of field dependence-independence, recently has reemerged as a measure of research interest and potential diagnostic value in neuropsychology. In the standard RFT, the subject experiences offsetting visual cues from a frame surrounding an embedded rod, while the subject's postural/vestibular cues provide the sense of verticality as the subject attempts to set the rod to vertical. The paper shows that RFTs not adhering to RFT parameters can reduce the test's visual framework impact experienced by the subject. Comparisons of neuropsychological studies will highlight that correct adherence to RFT testing conditions can strengthen RFT effects.
This review presents the parameters that have been studied which impact on subject performance on the RFT. It identifies how computer administered RFTs have been applied to enhance the study of the RFT parameters and make the RFT more accessible to the study of different diagnostic groups. The article also critiques studies by identifying how the RFT's parameters, study's design and statistical analysis may have diminished identifying the full effects of the RFT experience.
Parameters impacting judgments of verticality of the rod can include: perceived size of rod and frame, the gap between the ends of the rod and surrounding frame, presentation of the rod within an encompassing 3D visual framework that visually blocks out the surrounding environment, a dark room, instructions stressing egocentric vs allocentric strategies, double frame surrounding the rod to assess global perception effects, etc. Details are presented how gap size likely affected results in neuropsychology studies. Potentially, these and other experiments may be studied using computer administered RFTs.
Based on the descriptions of computer administered RFTs, this article suggested that incorporating these technologies can provide better understanding underlying the RFT, and in turn, understanding neuropsychology processes.
杆框测试（RFT）是一种衡量场依存独立性的方法，最近在神经心理学领域重新成为研究兴趣和潜在诊断价值的衡量标准。在标准的 RFT 中，主体会受到来自框架的视觉线索的影响，而主体的姿势/前庭线索则提供了垂直感，主体试图将杆设置为垂直。本文表明，不符合 RFT 参数的 RFT 会降低主体在 RFT 中体验到的视觉框架影响。对神经心理学研究的比较将突出表明，正确遵守 RFT 测试条件可以增强 RFT 效果。
本综述介绍了影响主体在 RFT 上表现的参数。它确定了计算机管理的 RFT 如何应用于增强 RFT 参数的研究，并使 RFT 更容易被不同诊断群体研究。本文还通过确定 RFT 参数、研究设计和统计分析如何可能削弱对 RFT 经验的全部影响，对研究进行了评价。
影响杆垂直判断的参数包括：杆和框架的感知大小、杆和周围框架末端之间的间隙、在视觉上遮挡周围环境的包含 3D 视觉框架中呈现的杆、暗室、强调自我中心与非自我中心策略的指令、环绕杆的双框架以评估全局感知效果等。介绍了间隙大小如何可能影响神经心理学研究的结果。这些和其他实验可能会使用计算机管理的 RFT 进行研究。
基于计算机管理的 RFT 的描述，本文建议将这些技术结合起来可以更好地理解 RFT 的潜在原理，进而理解神经心理学过程。
