We investigate the relationship between verbal and hand proprioception of slant. In Experiment 1 we demonstrate that verbally estimating free hand orientation produces overestimates by a factor of 1.67. These values are similar to those seen for verbal overestimates of slanted surfaces. In Experiment 2, participants positioned their hand to a ramp at 1 of 4 different orientations, and then verbally estimated the orientation of either their hand or the ramp. We show that verbal estimates of the ramp are a product of the orientation of their hand and the perception of the orientation of their hand. We discuss how this work is consistent with the proprioception calibration hypothesis that proposes that similar biases exist in both verbal estimates of visually perceived slant and proprioceptively perceived hand orientation and how this may explain free hand estimates to outdoor hills that are greater than actual hill orientation by a factor of ~2, but are still less than verbal (over)estimates.
我们研究了倾斜度的言语感知与手部本体感觉之间的关系。在实验1中，我们证明，对徒手方向进行言语估计会产生1.67倍的高估。这些数值与对倾斜表面的言语高估情况相似。在实验2中，参与者将手放置在4种不同方向之一的斜坡上，然后对其手部或斜坡的方向进行言语估计。我们表明，对斜坡的言语估计是其手部方向与对手部方向的感知的产物。我们讨论了这项研究如何与本体感觉校准假说相一致，该假说提出，在视觉感知的倾斜度的言语估计和本体感觉感知的手部方向中都存在类似的偏差，以及这如何解释对户外山丘的徒手估计比实际山丘方向大~2倍，但仍小于言语（过度）估计。
