Description
Summary:This paper reports the development shown by a number of subjects in the course of a series of tests in which they attempted to reproduce a simple figure which had been shown to them for ten seconds. The reproductions were made under varying conditions; sometimes with the eyes closed, sometimes with the result covered so that only the hand movement used in drawing could be seen, sometimes with both the movement and results of the drawing clearly visible. It is shown by a comparison of these results that the recognition of the figure is gradual, some subjects beginning at the beginning of the figure and working it out in detail, others beginning at other points in the figure. It is shown that the greatest amount of error is in the middle of the figure. It is shown that there is a difference in the rate of mastery of the size and relative position of the lines. It is shown that in certain cases parts of the figure may improve for a time, and the same parts may later be partially or completely overlooked. The series of tests is available for a demonstration of the improvement which arises from practice in a very short interval.
