When a very small point is cast in the neighborhood of various kind of figures, the point is influenced by the figures and is displaced in various directions. These directions and the quantity of displacement have been studied in detail in relation to (1) distance between a figure and the point; (2) size of the figure; (3) characteristics of the figure; (4) inside and outside of the contour figure.
The findings were as follows:
1. The point cast around a figure is displaced in the direction away from the figure at a place close to the figure. As it is cast farther away from the figure, iti is displaced toward the figure, showing the greatest magnitude of change in between, and as it is cast still farther away, the magnitude decreases gradually. (Cf. Figs. 4-7)
2. With change in the size of the figure the process of displacement of the point varies slightly-i.e. when the figure is larger, the highest magnitude of displacement occurs at a point slightly farther away from the figure. But it cannot be said that the magnitude of displacement always varies in proportion to the size of the figure. (Cf. Figs. 8-10)
3. On the outside of an angular figure, the point is drawn toward the figure, and the magnitude of displacement decreases is the distance is greater. On the inside of an angle, the point pulls away from the angle when placed near the angle, and in reverse as it is cast farther away it is drawn toward the angle. The greatest magnitude of displacement is attained in the environs of the line which connects the ends of the two sides of the angle, and from there on it gradually decreases. (Cf. Figs. 14, 15)
4. The point cast in a closed contour figure is on the whole drawn toward the center of the figure and the magnitude od displacement largest near the contour line while it decreases as the point is cast toward the center. (Cf. Figs. 11-13)
From these results it is concluded that the phenomenon of the displacement of the point seems to be influenced by the direction of the field force of the figures in the psycho-physical field.
