An Analytical Study on Cognitive Process of Natural Phenomena (IV) : EOG induced by "Remembering", "Describing" and "Interpreting"

Abstract

This is a basic research study to make clear the cognitive process in children's learning behavior. An analysis of children's behavior and psycho-physiological activities is used as a means to this end. The study was undertaken to measure them in undergraduate students in place of children, as induced by "Remembering", "Describing" and "Interpreting". Such activities were recorded in successive tests measuring changes in Electro-oculogrphy (EOG) induced by saccadic eye movement. By means of EOG testing, 1) Interpretation of changes of natural phenomena, description of a natural thing and remembrance of one's experiences were measured from each student. 2) Various EOGs induced by saccadic eye movements were recorded for each student, according to each remembering, describing and interpriting. The subjects were six undergraduate students. The experiment was undertaken using three kinds of small experiment. One was to solve a problem concerned with changes of natural phenomena, another was to describe a natural thing and the other was to remember one's experiences with regard to the natural thing. These natural thing and phenomena were presented by means of the concrete materials. The results are summarized as follows; 1) There was no significant difference between the appearance rate of the EOG which is more than 50μV induced by "Remembering" and "Describing". 2) The appearance rate of EOG which is more than 50μV induced by "Interpreting" was higher than that the "Describing" and than that by "Remembering" (p < 0.01). 3) The appearance rate of EOG which is more than 50μV induced by a interpretative scene in "Interpreting" was higher than that by a descriptive scene in it (p <0.01). 4) The appearance rate of EOG which is more than 50μV induced by a descriptive scene in "Interpreting" was higher than that by "Describing" (P < 0.01). The results show a significant difference of the appearance rate of the saccadic eye movement among induced by "Remembering", "Describing" and "Interpriting". The differences of "Remembering", "Describing" and "Interpreting" are the degree and extent of thought operations and whether the thought operations have a direction or not. It may be assumed from these results that the appearance rate of EOG correspond to the degree and extent of thought operations and whether the thought operations have a direction or not.
