MACHINE FOR TESTING THE HUMAN BRAIN.
Professor Carl Seashore, of the lowa State University, has invented a machine which he calls the "Psychograph," designed for. testing the human brain. The machine ia simple,, and consists of two parts, one looking like a typewriter and the other like the recording apparatus on a telegraph.1 instrument. To make the desired test, a person sits in. front of the instrument arid places a finger, on each of the four keys. Those keys are labelled with colours. A key of the colour touched by the person being tested is then, touched by the operator, and by electrical action the colour in a dot is immediately changed. This colour key is pressed, another colour appears, and the action is continued as long as desired. Another part of the machine records, by means of five pencils working on a continuous tape, the. amount of work done, the time required for each action, and the quality of the work.
