2.2 Measuring system

Before starting those practical experiments, we had been developing the measuring system for individual traits [12], regarding human information processing. This system is simulated interactive communication between an instructor (A) and a learner (B) with using ICT (a) ! (b) ! (c) ! (d) (Figure 4). In the field of educational technology studies, they call this interaction as learning process. When the learner responses to the instructor (A) after the information or instruction for assignments from the instructor (A) conveyed to her or him, the one session of activity has been considered as coming into effect of learning (Figure 5).

From this theory of learning processing, we predicted that language information processing might be the same as each other (Figure 5, ①). Then, instead of the instruction or assignment, we decided to use questionnaires of YGPI (Yatabe-Guilford Personality Inventory), which is consisted of 120 short sentences and 12 factors (10 of 120 each), and more, they are composed of two main factors, emotional and non-emotional factors. Subjects are required to choose responses to questionnaires among "yes," "no," or "either," comparing with their daily activities or behavior. The system also measures their response time from the start of presenting the questionnaire to subjects' replies (Figure 5, ② and ③). Card has

introduced the theory that the perceptional system (τp), cognitive system (τc), and motor system (τM) are involved in simple reaction time [17, 18].
