EMPLOYMENT PSYCHOLOGY 
This test has also been used with success in Germany in choos- 
ing shop apprentices. 
Patten (132) used a similar apparatus with students in the 
College of Engineering of the University of Wisconsin. Instead 
of pencil and printed diagram he used a metal stylus and a hard- 
rubber plate in which six small brass pegs were imbedded to form 
a hexagon, flush with the surface of the plate. As the stylus 
traveling over the hard-rubber plate came in contact with a brass 
spot, a buzzer sounded. The time to make the circuit of the six 
brass spots correlated —.423 with the quality of lathe work 
turned out in the Shop Practice Course. 
Explanation of O’Connor Finger Dexterity Test (Figure 6). 
The equipment for this test consists of 300 brass pins and a flat 
metal plate (mounted on an oak board) in which 100 holes are 
drilled part way through. The subject, using the right hand only, 
takes the pins 3 at a time from a tray in which they are piled 
loosely, and places 3 in each drilled hole as rapidly as possible. 
The test is scored in terms of the time required to complete the 
task. Individuals differ widely in this test, the fastest finishing 
in less than 6 minutes, while the slowest require from 12 to 15 
minutes. 
Hines and O’Connor (70) have reported results obtained with 
the use of this test at the West Lynn Works of the General Elec- 
tric Company. Seventy-seven girls engaged in fine meter or 
instrument work were tested. Of these, 60 proved satisfactory, 
6 failed and left, and 11 left before their proficiency could be 
judged. Of those scoring 7.50 minutes or less, 91% proved satis- 
factory, and none were failures. Of those scoring 7.51 minutes 
or more, 45% proved satisfactory, and 27% were failures. 
Explanation of the Wechsler Chauffeur Test (Figures 7 and 8). 
The subject is seated in a dummy car which resembles an ordi- 
nary cab. He is instructed to look straight in front of him at a 
gray board 10 feet from where he is seated, upon which intermit- 
tent lights of different colors are flashed at irregular intervals. 
When seated in the car he is told to take the position for ordinary 
driving, that is, his left foot to the left of the clutch, his right foot 
on the accelerator, and his hands on the steering wheel. He is 
told to imagine that he is driving along at ordinary speed, and 
that in no case is he to press down upon the gas which is already 
being fed at the proper rate. However, upon the flash of certain 
lights, which serve as signals, he must react in certain ways by 
an appropriate movement of the hands or feet, or both. For 
instance—at the flashing of a yellow light (meaning to slow up)
