The Artifacts Collection features more than 1,000 instruments, apparatus, and other objects from the history of psychology and related sciences.
The collection includes devices from the late nineteenth century “brass-and-glass” era of psychology, including kymographs, chronoscopes, and ergographs. It also contains the “baby-tender” popularized by B. F. Skinner in the 1940s, a diathermy machine used to calm patients in asylums, and early prototypes of home electronic monitoring devices designed by psychologists.
The CHP collection is home to this teaching machine, patented by Sidney Pressey in 1928. Students press one of the four keys to respond to a multiple choice question viewed through a window on the device. When the machine is in "teaching mode," it will not advance to the next question until the student answers correctly.
