Richard Lester Solomon (October 2, 1918

– October 12, 1995) was a psychologist well known for his work with in comparative psychology, as

well as his opponent-process theory of

emotion. Solomon attended Brown

University, where he earned a bachelor's degree (A.B.)

in 1940, a master's degree (A.M.)

in 1942, and a doctorate (Ph.D.) in 1947. Solomon

won several awards for his scientific achievements, including the Distinguished

Scientific Contribution award of the American Psychological

Association and the Howard Crosby WARREN Medal of the Society of

Experimental Psychologists. Additionally, he was elected to both

the American

Academy of Arts and Sciences and the National

Academy of Sciences. He also held several honorary posts, and edited

the Psychological Review. During

his time at Harvard University, Solomon conducted research into avoidance learning. In his

experiments, he placed dogs into shuttle boxes with two chambers. The lights

would then come on in the side where the dog was. A few seconds later, one half

of the chamber would become electrified. To avoid shock, the dog would run to

the other chamber. Eventually, the dogs learned to avoid shock entirely by

running to the other side in the interval between lighting and electrification.
