Previous work has shown that overestimates of geographic slant depend on the modality used (verbal or haptic). Recently, that line of reasoning has come into question for many reasons, not the least of which is that the typical method used for measuring "action" has been the use of a palm board, which is not well calibrated to any type of action toward slanted surfaces. In the present work, we investigated how a remote haptic task that has been well calibrated to action in previous work is related to verbal overestimates of slanted surfaces that are out of reach. The results show that haptic estimates are perceptually equivalent to the verbal overestimates that have been found in numerous previous studies. This work shows that the haptic perceptual system is scaled in the same way as the visual perceptual system for estimating the orientation of slanted surfaces that are out of reach.
先前的研究表明,对地理倾斜度的高估取决于所使用的模态(言语或触觉)。最近,这一推理思路因诸多原因受到质疑,其中最主要的原因是,用于测量“动作”的典型方法是使用手掌板,而该手掌板并未针对任何朝向倾斜表面的动作进行良好校准。在本研究中,我们探究了一项在先前研究中已针对动作进行良好校准的远程触觉任务,与对够不着的倾斜表面的言语高估之间有何关联。结果表明,触觉估计在感知上等同于先前众多研究中发现的言语高估。这项研究表明,在估计够不着的倾斜表面的方向时,触觉感知系统与视觉感知系统的缩放方式相同。
