(8) There may be failure to comprehend how one may project space in three dimensions upon a plane. (9) Manual skill may fail. (10) There may be no artistic sense. (11) Inability to draw may arise from a combination of various of these deficiencies. Manuel has offered the following analysis, after study of persons especially talented: The following characteristics, each an independent or partially independent variable, seem closely related to ability in drawing: (1) The ability mentally to note a visual form, and, by certain lines and areas, to reproduce it or significant features of it. (2) Ability to observe. (3) Ability to select from a complex visual situation the most representative and the most beautiful aspects. (4) Memory for visual forms. (5) Ability mentally to manipulate visual forms. (6) Ability to control hand movements in accordance with visual percept or image. (7) Ability to invent, to bring together into new artistic combinations the elements of different visual experiences. (8) Ability to judge the beautiful in line, form, color, and composition. (9) Ability to discriminate differences in color. (10) Ability to discriminate differences in visual magnitude. (11) Acuity of vision. (12) Interest in the act and products of drawing. (13) General intelligence. These two analyses may serve as samples, since they include practically all the elements suggested by any other investigators. Jones has recently furnished us with additional evidence that memory of objects visually perceived and perception of perspective are probably important contributors to drawing ability. Among 264 school children in the seventh and eighth grades of the Evanston public schools, a correlation was found of .83 between visual memory and ability to draw. Perception of perspective and visual memory yielded a coefficient of .85. As a result of administering more than twenty tests to 19 individuals gifted in drawing, Manuel concludes that, “Persons talented in drawing exhibit great individual differences in their psychophysical characteristics.” Nevertheless, tests devised to measure status in the traits listed in the analyses which have been made, would be expected to yield, finally, a psychograph of talent in each of the various kinds of drawing. Persons approximating these psychographs could then be identified as talented in drawing, and those deviating widely from them could be classified as deficient in ability to draw. The invention and standardization of such tests is a matter for further research. At present we have no means of gauging talent in drawing except by grading a finished product on a scale of drawings, like Thorndike’s “Scale for Measuring Achievement in Drawing.” Such a means does not always adequately separate talent from training.
