Shocks came randomly and seemed inevitable, which caused learned helplessness, the dogs assuming that nothing could be done about the shocks. This belief persisted until the 1970s, when Paul Ekman and Wallace Friesen, psychologists at the University of California at San Francisco, captured the precise muscular coordinates behind 3,000 facial expressions in their Facial Action Coding System, known as FACS. During the course of the experiment, the researchers recorded the participants' facial expressions. How quickly someone can abuse their control when put into the right circumstances.
