The purpose of this study is to propose and assess a method to reflect psychological evaluations precisely. The proposed method principally aims to dissolve the incongruity of evaluative words with regard to subjects and objects. In a questionnaire, the evaluative words which are used in inner speech are shown allinclusively and independently in order to reflect the individuals' evaluating viewpoint on the surroundings. Subjects reply to questions by choosing the words which are equivalent to their feelings or sensations. The meaning of each word and the relationship among the words are derived from the questionnaire results. Two kinds of experiments where subjects were exposed to the controlled air temperatures. Thermal evaluation using the ASHRAE scale and the word-choice method were compared. As a results, it was revealed that the word-choice method was a valid way to grasp the difference of psychological evaluations.
