Christian Ruckmick, who contributed one important monograph to the Payne Fund Motion Picture Studies, praised the emotion-reading power of the psychogalvanometer, which was essentially a lie detector that measured a variety of physiological changes and then recorded them on film.
For Ruckmick, the psychogalvanometer engaged deeply with people's emotions so that he didn't have to, leaving him to observe the emotions of the new technological age from an appropriate--though equally technologized--distance.
For example, in 1948 the corporate research director of Ford set up a psychogalvanometer testing facility to evaluate advertising and car design in the Rotunda.
