EMPLOYMENT PSYCHOLOGY II 4 again. The experimenter believed that an operator could do this more rapidly and successfully at the beginning of a day when fresh, than at the end of a day when fatigue had set in. He further believed that if this could be dem onstrated, it would also follow that machine operators were more liable to accidents toward the end of the day than in the morning, for the same reason. The manner in which this experiment was conducted and the merits of its results are not of particular interest here. However, the apparatus seemed very promising for the purpose of separating the slower from the faster operators. A similar apparatus was therefore constructed and tried out. To begin with, tests were given to twenty operators in order to familiarize the experimenter with the use of the apparatus, the giving of directions for it, and scoring the results. As a result of these preliminary tests, certain difficulties were discovered. First, the construc tion of the apparatus was such as to make accuracy of performance impossible. For instance, each time the arm struck the cube on the square it would knock it off onto a different part of the table. This condition became worse as the speed of the rotating arms was increased, and fre quently the cube would be knocked entirely off the table and would have to be picked up from the floor. This factor might have been a desirable one, and a measure of the operator’s resourcefulness, had it not been for a second difficulty. It was practically impossible to score the results. The operator hardly ever placed the cube exactly on the painted square, but each time the angle or degree of displacement was different, making it ex tremely difficult for the experimenter to make any score on the mistakes of the operator. Even if the observer had been able to estimate the misplacement in every
