Experimental verification of hierarchical structure in Kansei processing

感性是人类从感官到精神状态的反应，即，敏感性，感觉，感性，感觉，美学，情感，情感和直觉。本研究提出一个感性过程的模型，以探讨感性的特性。该模型由感性判断的层次结构和两个智能数据库组成。假设层次结构由五个级别构成，即，在2003年度，为了弄清感性的等级结构，进行了两个使用感性的语言表达的实验。在第一个实验中，60名被试对215个言语表达的感性表达频率进行了评级，并选择了100个表达作为代表。在第二个实验中，测量了100个表情之间的心理距离，并使用MDS（多维标度）技术进行分析。在MDS获得的100个言语表达的二维结构中，其中一个轴清楚地显示了感性的层次结构。在2004年度，我们对智力数据库对感性判断的影响进行了研究。音乐被用来唤起感性，玩家的信息被用来激活情报数据库。14名被试对8种由音乐和玩家信息组成的刺激进行了12种言语表达的评分。结果表明，即使音乐声音相同，演奏者的信息也会显著影响被试的感性。这些实验结果表明，本研究假设的感性决定层次是有效的。

Kansei is the human reaction from sensory to mental state, i.e., sensitivity, sense, sensibility, feeling, esthetics, emotion, affection and intuition. In this investigation, a model of Kansei process intrinsic to a human being was proposed in order to examine the property of Kansei. The model consisted of a hierarchy for Kansei determination and two databases in terms of intelligence. The hierarchy was assumed to be constructed with five levels, i.e., basics, pleasantness, liking, art, and the absolute Kansei.In FY 2003, two experiments using verbal expressions of Kansei were carried out to clarify the hierarchical structure. In the first experiment, 60 subjects rated 215 verbal expressions with respect to the frequency of Kansei expression, and 100 expressions were selected as representative. In the second experiment, psychological distances among the 100 expressions were measured, and analyzed using a MDS (multidimensional scaling) technique. In the obtained two-dimensional configuration of the 100 verbal expressions by MDS, one of the axes clearly showed the hierarchy of Kansei. Besides the assumed five levels, the level of emotion was found.In FY 2004, the effects of intelligence databases on Kansei determination were examined. Music was used to evoke Kansei, and information of players was used to activate the intelligence database. Fourteen subjects rated eight stimuli consisted of music and player's information for 12 verbal expressions. As a result, it was shown that the player's information has significant effects to change subjects' Kansei even if the musical sounds were the same. The effects were restricted for the higher levels in the hierarchy.These experimental results indicate that the hierarchy of Kansei determination assumed in this investigation is valid.
