Abstract
This is a basic research study to clarify the necessary conditions for organizing the school science teaching based on child's cognitive process. The objective of this experiment is to make clear the psycho-physiological activities induced by the level of information processing. The study was undertaken to measure the electroencepharogram (EEG), plethysmogram (PTG) and electro-oculogram (EOG) in ten male students, in place of children, as induced by recognizing identity and difference. Cluster analysis was used to analyze them. The experiment had five stages which were rest time (RES), collecting information for recognizing identity (CII), conclusion of recognizing identity (CRI), collecting information for recognizing difference (CID), and conclusion of recognizing difference (CRD). The results were summarized as follows: (1) Psycho-physiological activities induced by CII and by CID showed the same activities. (2) Psycho-phrsiological activities induced by CRI and by CRD showed a different activities. (3) Psycho-physiological activities induced by CII and by CRI showed a different activities, and also, CID and CRD had a different activities. (4) RES showed a different psycho-physiological activities from the other. (5) The combination on activities of EEG, PTG and EOG showed different types depended on the level of information processing. From these, it is considered that psycho-physiological activities are changed according to the level of information processing and it is possible to grasp them to a certain degree by analyzing EEG, PTG and EOG.
