Physiological and Psychological Indexes showing "PLEASURE" in Vibration

振动并不总是令人不快；人们有时会觉得它令人愉快。当给予与身体特定条件相对应的有利刺激时，个体感觉良好，有时还会感到愉悦。本研究的目的是从心理学、物理学和生理学的角度来研究振动引起的快感的诱导。在这项研究中，为了评估快乐-不快乐，对感觉进行了建模。特别是通过多维尺度方法对愉悦感觉进行分类，快乐构建轴由积极的愉悦--消极的愉悦--和“通过去除而获得的愉悦--通过满意获得的不愉快--”构成。其次，使用摇椅进行生理和心理评价实验，以评价振荡刺激下的快感。之所以选择摇椅进行实验，是因为它能产生较长周期的振动，让人感觉比较舒服。此外，他们还可以负责控制振荡。为了评估受控垂直振动刺激下的快感，人们被要求坐在附加在振动座椅上的汽车座椅上，并受到任意垂直振动。结果证实，振动可以产生负性快感和正性快感，揭示了振动和振动刺激下评价快感的有效生理和心理指标。

Vibration is not always unpleasant; people sometimes find it pleasant. When favorable stimulation that corresponds with a specific condition of a body is given, the individual feels fine and sometimes feels pleasure. The purpose of this research is to investigate the induction of a feeling of pleasure caused by vibration from the viewpoints of psychology, physics, and physiology. In this research, feelings were modeled in order to evaluate pleasure-displeasure. As a result of classification of the feeling of pleasure in particular, through a multidimensional scaling method, pleasure-constructing axes consisted of positive pleasure-negative pleasure, and' pleasure obtained by removing, displeasure-pleasure obtained by satisfaction. Next, physiological and psychological evaluation experiments were carried out using a rocking chair in order to evaluate the feeling of pleasure under oscillation stimulation. The rocking chair was chosen for the experiments because it could give long-period vibration with which people feel comparatively comfortable. In addition, they could be in charge of controlling the oscillation. In order to evaluate the feeling of pleasure under controlled vertical vibration stimulation, people were made to sit in an automotive seat attached to a vibration seat and subjected to arbitrary vertical vibration. As a result, it was confirmed that the feeling of pleasure such as the negative pleasure and the positive pleasure could be induced by vibration, and effective physiological and psychological indexes for evaluating the feeling of pleasure, under oscillation and vibration stimulation, were revealed.
