研究关于输入、本体感受和输出对表面触觉认知的影响,旨在探索运用触觉识别质地密度逐渐变化的表面时,理论关于表面粗糙度恒定的情况下,主动手指运动产生的信息不影响触觉认知的解释是否仍然成立。实验采用表面质地密度呈正态曲线式逐渐变化,组成正负两组变化方向。正方向变化为表面质点密度向中逐渐增大,与手指触摸运动的加减速方式一致;负方向变化为表面质点密度向中逐渐减小,与手指触摸运动的加减速方式相反;另外包括一个表面密度不变的平面。让被试辨别表面质地密度变化的方向,结果发现被试能够很好地判别表面质地密度变化的方向,但在判别正向变化的表面时显得更准确;当表面密度没有变化时,被试倾向于判别为正向变化。这一发现没有支持表面密度恒定的触觉认知解释模型。与常规直觉相反,研究还发现即时反馈并没有改进触觉识别,反而降低了辨别的正确率。质地密度逐渐变化的触觉识别在变化的大小、准确和自信心方面都显示了不同,但没有发现认知学习作用该触觉任务辨别的过程。基于这些发现,文章讨论了触觉质地感知和有关存在的理论解释模式。
To study the effects of input, proprioception and output on the surface tactile perception, and to explore the use of tactile recognition of the surface texture with gradual changes in density, the theory that the information generated by active finger movement does not affect tactility when the surface roughness is constant Knowledge of the interpretation is still true. The density of the surface texture used in the experiment shows a gradual change in the normal curve, forming a positive and negative direction of change for both groups. The positive direction changes gradually as the surface mass density gradually increases, which is consistent with the acceleration / deceleration mode of finger touch movement. The negative direction changes as the surface mass density gradually decreases toward the middle, opposite to the acceleration / deceleration mode of finger touch movement. In addition, The same density of the plane. The subjects were asked to discern the direction of the surface texture density change. The results showed that the subjects were able to determine the direction of the surface texture density change well, but it was more accurate in discriminating the surface of the positive change. When the surface density did not change, To determine the positive changes. This finding does not support the tactile cognitive interpretation model of constant surface density. Contrary to conventional intuition, the study also found that instant feedback did not improve tactile recognition, but rather reduced the accuracy of discernment. Tactile recognition of a gradual change in texture density shows differences in size, accuracy, and self-confidence, but no cognitive learning role is found for the tactile task discrimination. Based on these findings, the article discusses the tactile texture perception and the related theoretical explanations of existence.
