The impact on the decision of responses to an ordinal Japanese personality inventory presented by letters or sound voices (L/S) has been examined. The tasks of this inventory comprise 120 question divided into two mental categories: emotionality or introversion-extroversion (E/I, total 240 tasks). A total of 18 university students have participated in the experiment where they were asked to reply to the tasks using the answer “Yes,” “No,” or “I don’t know” (Y/N/?). The result of the analysis of four factors (L/S, E/I) has shown significantly different responses for all the students’ answers. For the L/S factor comparison, the number of Y by S was significantly larger than that by L: in contrast, the number of N by L was significantly larger than that by S. The total response time of N was significantly longer than that of Y at a 1% level in both factors for L and S. Individually, four students’ response times to E tasks in the L factor were significantly different between Y and N. Contrary to the total results, however, three of those four selected Y for a significantly longer time than N. The individual responses and reaction times to tasks have been observed in a dot diagram: the factors have individual correlations between response and reaction times, and these have different effects on their decisions. Considering the differences of impacts on decisions, the importance of instructional design for e-learning, digital materials and so on has been examined.
