双手触觉体积感知是指通过双手获得体积信息的体感，影响这种感知的特征仍然不清楚。本文探讨了目标物体的形状和手指对双手触觉知觉的影响，此外，协会的双手触觉功能障碍和非精神病患者的典型特征进行了调查。二十名被蒙住眼睛的参与者使用新开发的双手触觉体积呈现设备，用双手辨别不同形状（四面体、立方体或球体）和手指对（高灵敏度或低灵敏度对）条件下规则固体物体的体积变化。然后使用中文版的分裂型人格问卷（Schizotypal Personality Questionnaire）将辨别阈值与分裂型人格特质相关联。目标物体的形状和手指对双手触觉体积感知显着影响。在高灵敏度对条件下，四面体刺激的体积辨别阈值显着高于立方体或球形刺激，但在低灵敏度对条件下，形状之间没有显着差异。此外，高敏感对的体积辨别阈值与典型人格问卷的偏执评分相关。研究结果提供了初步的证据，了解双手触觉体积感知的性质，包括对象，个人和对象的个人接口的属性。
Bimanual haptic volume perception refers to somatosensory access to volume information through both hands, and the characteristics that influence this perception remain unclear. This article investigated the influence of target object shapes and finger pairs on bimanual haptic perception; in addition, associations of bimanual haptic impairment and schizotypal features in nonpsychotic individuals were investigated. Twenty blindfolded participants bimanually discriminated volume variations in regular solid objects under different shape (tetrahedron, cube, or sphere) and finger pair (high- or low-sensitivity pairs) conditions using a newly developed bimanual haptic volume presentation device. Discrimination thresholds were then associated with schizotypal traits using the Chinese version of the Schizotypal Personality Questionnaire. Target object shape and finger pairs significantly influenced bimanual haptic volume perception. Volume discrimination thresholds were significantly higher with the tetrahedron stimuli than the cubic or spherical stimuli in high-sensitivity pair conditions, but no significant differences among shapes were found in low-sensitivity pair conditions. Moreover, volume discrimination thresholds with high-sensitivity pairs were correlated with the paranoid score of the schizotypal personality questionnaire. The findings provide initial evidence toward understanding the nature of bimanual haptic volume perception, including the properties of objects, individuals, and object-individual interfaces.
