Haptic perception is used in the anatomy laboratory with the handling of three-dimensional (3D) prosections, dissections, and synthetic models of anatomical structures. Vision-based spatial ability has been found to correlate with performance on tests of 3D anatomy knowledge in previous studies. The objective was to explore whether haptic-based spatial ability was correlated with vision-based spatial ability. Vision-based spatial ability was measured in a study group of 49 medical graduates with three separate tests: a redrawn Vandenberg and Kuse Mental Rotations Tests in two (MRT A) and three (MRT C) dimensions and a Surface Development Test (SDT). Haptic-based spatial ability was measured using 18 different objects constructed from 10 cubes glued together. Participants were asked to draw these objects from blind haptic perception, and drawings were scored by two independent judges. The maximum score was 24 for each of MRT A and MRT C, 60 for SDT, and 18 for the drawings. The drawing score based on haptic perception [median = 17 (lower quartile = 16, upper quartile = 18)] correlated with MRT A [14 (9, 17)], MRT C [9 (7, 12)] and SDT [44 (36, 52)] scores with a Spearman's rank correlation coefficient of 0.395 (p = 0.0049), 0.507 (p = 0.0002) and 0.606 (p < 0.0001), respectively. Spatial abilities assessed by vision-based tests were correlated with a drawing score based on haptic perception of objects. Future research should investigate the contribution of haptic-based and vision-based spatial abilities on learning 3D anatomy from physical models.

从触觉感知和基于视觉的空间能力中提取的对象

触觉感知在解剖实验室中用于处理三维 (3D) 剖面、解剖和解剖结构的合成模型。在之前的研究中，基于视觉的空间能力被发现与 3D 解剖知识测试的表现相关。目的是探讨基于触觉的空间能力是否与基于视觉的空间能力相关。由 49 名医学毕业生组成的研究小组通过三项单独的测试来测量基于视觉的空间能力：重新绘制的两个维度 (MRT A) 和三个维度 (MRT C) 的范登堡和库斯心理旋转测试以及表面发育测试 (SDT)。基于触觉的空间能力是使用由 10 个立方体粘合在一起构成的 18 个不同物体来测量的。参与者被要求通过盲目的触觉感知来绘制这些物体，并由两名独立评委对图画进行评分。 MRT A 和 MRT C 的最高分均为 24 分，SDT 为 60 分，绘图为 18 分。基于触觉感知的绘图分数 [中位数 = 17（下四分位数 = 16，上四分位数 = 18）] 与 MRT A [14 (9, 17)]、MRT C [9 (7, 12)] 和 SDT [44] 相关(36, 52)] 的 Spearman 等级相关系数分别为 0.395 ( p  = 0.0049)、0.507 ( p  = 0.0002) 和 0.606 ( p  < 0.0001)。通过基于视觉的测试评估的空间能力与基于物体触觉感知的绘画分数相关。未来的研究应该调查基于触觉和基于视觉的空间能力对从物理模型学习 3D 解剖学的贡献。
