It can be considered that the process of conviction plays an important part in many real life situations such as knowledge acquisition, opinion formation and so on. Clarifying the conditions that control the subjective feeling of "being convinced", we can design the effective methods in wide range of areas of education. The present study was planned to describe the structure of situational aspects in which the subjective feeling of "being convinced" emerges. We collected 214 reports of episode concerning conviction from 109 university students. Through the contents analysis, these reports were summarized into 61 items. Each of them describes the concrete situation in which the conviction increase or decrease. This 61- item questionnaire was presented to 682 university students. They were required to evaluate the degree how much do they feel the subjective feeling of being convinced in 5-point scale. The factor analysis to the acquired data reveals that two large factors, logical and emotional, controls the subjective feeling of being convinced. The detailed aspects of obtained data will be discussed at the time of presentation.
