Abstract

This paper is concerned with the first part of a series of experiments involving the image formation process of simple meaningless line figures. Iijima (1973) proposed a “mathematical figure theory” in his pattern recognition theory. In this theory he emphasizes a definition of the relationship between original figure and figure image formed on the retina before feature extraction processing. This paper reports an attempt to find clues of basic rules of ordinary human perceptional behavior. Such practical study of pattern recognition psychology of form perception are scarce.
The main purpose of Experiment 1 to identify the general characteristics which affect the image formation process when a person views unknown figures. Factor analysis has been performed on the scale value of “conspicuous” figure which were selected intuitively out of the presented stimulus figures. Some characteristics of figures were extracted as image formation factors. Experiment 2 was conducted to verify the results of Experiment 1 from another point of view. The data for “impressive” figures was collected by stimulus reduction using a tachistoscope. In Experiment 3, the results of above two experiments were validated more directly in observation of eye movement responces for stimulus figures. From these results, it is indicated that the practical methods used here may be an effective approach to investigate the basic elements of human pattern recognition.
