34^ EMPLOYMENT PSYCHOLOGY psychologist or the trained interviewer must continue the process. When, by a series of test questions, it has been discovered that the applicant has a general knowledge of the work in question, the psychologist will give him a series of standard tests, such as is given to all other appli cants for that work, in order to discover more closely what the applicant’s ability really is. These tests will be based upon the actual work of the position in question. In the case of the mechanical trades, applicants are first shown an assortment of odd tools, and asked to point out those which are used in their trade. Then, as a more refined test, they are given a series of hypothetical tasks and asked to point out the tools which would be used in the performance of each task. As a still further test, a set of typical drawings is displayed, and the applicant asked to point out the work which each drawing calls for. A tool maker or machinist, for instance, may be shown a series of blueprints representing operations of the various machine tools, and he may be asked to state, in each case, which of the machines would be involved in perform ing the work called for by each of the drawings. This is a very simple test but one which reveals a great deal about a man’s ability. Finally, the applicant may be requested to give a demonstration of his knowledge by performing some actual work on tasks assigned by the interviewer. The draftsman may be asked to do some lettering, to make a sketch, to design a fixture, or to work out a gauge. The machinist may be given a task on a machine which will involve certain essential operations. The stenographer is tried out on some actual dictation and typing. The accountant will be given some entries to make, etc., etc. Several objections are likely to be raised at this point.
