There might have existed two loops for human information processing: one might be a positive feedback control (PFC) and the other might be a negative feedback control (NFC). Depending on students, which they might choose one during the problem solving would be different and it might be clarified by analyzing

a. In the case of PFC, Loop of (1)(2)(4)(5), (Figure 6), encoded words into symbols might be feedback directly to perceptive organs in order to comprehend the next word along with the context of given each

questionnaire. Therefore, this type might have a tendency toward eidetic with short-term memory (STM) to make their decisions in a short time without

b. In the case of NFC, Loop of (1)(2)(4)(6)(7)(3)(4)(8), (Figure 6), encoded words into symbols might be feedback control after phonologization with image schema and matching meanings of the words with sound voice by long-term memory (LTM). If there are conflicts between them, s/he might need to modify either one of them; then, the results would be conveyed to the cycle of feedforward control (Figure 6; (3)). In this case, they need time to

c. Most of the students might use both loops to solve problems and make decisions for replies. How they might choose one, depending on

And more over, this tendency might have effects on their personality.

Twenty-eight university students participated in this experiment.

The experiment took place from January to March in 2015.

The purpose of prototype experiments is to calibrate the measurement system.

The participants were divided into two groups for a counterbalance depending on orders of the way of presentation by sound voice or letters. Prototype experiments are implemented twice to the same participants in the same way and conditions in January and March, for example, the arrangement of laptop displays on the

questionnaires, would be effects on their performances.

this chapter, we will examine hypotheses of "dual loop theory" as below.

Each comparative experiment plans to obtain 240 responses and response time per person. Total amount of data should be 6720 for each element.
