Stanley Schachter

Stanley Schachter (April 15, 1922 – June 7, 1997) was an American social psychologist, who is perhaps best known for his development of the two factor theory of emotion in 1962 along with Jerome E. Singer. In his theory he states that emotions have two ingredients: physiological arousal and a cognitive label. A person's experience of an emotion stems from the mental awareness of the body's physical arousal. Schachter also studied and published a large number of works on the subjects of obesity, group dynamics, birth order and smoking. A Review of General Psychology survey, published in 2002, ranked Schachter as the seventh most cited psychologist of the 20th century.

Schachter was born in Flushing, New York, the son of Anna (Fruchter) and Nathan Schachter. His parents were both Romanian Jews, his father from Vasilau a small village in Bukovina and his mother from Radauti. As a young man, Schachter initially studied Art history at Yale University. He obtained his Bachelor’s degree in 1942, and went on to pursue his Master's in Psychology, also at Yale, where he was influenced by Clark Hull. After earning his Master’s in 1944, Schachter joined the United States Armed Forces, where he served until 1946. During his two years in the Armed Forces, Schachter obtained the rank of sergeant. He worked at the Biophysics Division of the Aero-Medical Laboratory of Wright Field in Riverside, Ohio, studying the visual problems experienced by pilots in flight.
