E. W. Jacobs, Marion T. Gaines · Teaching of Psychology · 1986
For approximately $600, Apple IIe owners can purchase equipment for collecting physiological data. Electromyograph (EMG), galvanic skin response (GSR), skin temperature (TEMP), and heart rate (HR) data can be recorded at user-specified intervals, displayed on a monitor, saved to a disk, and printed on paper. The system is flexible, and has been used in classroom demonstrations, relaxation training, and student research projects.
