traits, and then theoretically to determine for which economic tasks the presence of these qualities would be useful and for which tasks their absence or their deficiency would be fatal.  Common sense may be sufficient to lead us a few steps in that direction.  For instance, if we find by psychological examination that an individual is color-blind for red and green sensations, we may at once conclude, without any real psychological analysis of the vocations, that he would be unfit for the railroad service or the naval service, in which red and green signals are of importance.  We may also decide at once that such a boy would be useless for all artistic work in which the nuances of colors are of consequence, or as a laborer in certain departments of a dyeing establishment, and that such a color-blind girl would not do at a dressmaker’s or in a millinery store.  But if we come to the question whether such a color-blind individual may enter into the business of gardening, in spite of the inability to distinguish the strawberries in the bed or the red flowers among the green leaves, the first necessity, after all, would be to find out how far the particular demands of this vocation make the ability to discriminate color a prerequisite, and how far psychical substitutions such as a recognition of the forms and of differences in the light intensity, may be sufficient for the practical task.  Moreover, where not merely such mental defects, but more subtly shaded variations within normal limits are involved, it would be superficial, if only the mental states were examined and not at the same time the mental requirements of the vocations themselves.  The vocation should rather remain the starting-point.  We must at first find out what demands on the mental system are made by it and we must grade these demands in order to recognize the more or less important ones, and, especially for the important ones, we must then seek exact standards with experimental methods.

Such an experimental investigation may proceed according to either of two different principles.  One way is to take the mental process which is demanded by the industrial work as an undivided whole.  In this case we have to construct experimental conditions under which this total activity can be performed in a gradual, measurable way.  The psychical part of the vocational work thus becomes schematized, and is simply rendered experimentally on a reduced scale.  The other way is to resolve the mental process into its components and to test every single elementary function in its isolated form.  In this latter case the examination has the advantage of having at its disposal all the familiar methods of experimental psychology, while in the first case for every special vocational situation perfectly new experimental tests must be devised.
