Science Museum of Minnesota The Psychograph machine consisted of 1, 954 parts in a metal carrier with a continuous motor-driven belt inside a walnut cabinet containing statements about 32 mental faculties. These faculties were each rated 1 through 5, “deficient” to “very superior, ” so that there were 160 possible statements but an almost unlimited number of possible combinations. The “score” was determined by the way the 32 probes, each with five contact points in the headpiece, made contact with the head. The subject sat in a chair connected to the machine and the headpiece was lowered and adjusted. The operator then pulled back a lever that activated the belt-driven motor, which then received low-voltage signals from the headpiece and stamped out the appropriate statement for each faculty consecutively.
