Schachter Singer Theory

The Schachter-Singer theory, also known as the two-factor theory of emotion, is a psychological model that attempts to explain the complex and multifaceted nature of human emotions. Developed by psychologists Stanley Schachter and Jerome Singer in the 1960s, this theory posits that emotions are the result of a combination of two factors: physiological arousal and cognitive labeling. According to this theory, emotions are not solely the result of internal physiological states or external environmental stimuli, but rather the result of an interaction between the two.
Introduction to the Schachter-Singer Theory

The Schachter-Singer theory was developed as a response to the prevailing theories of emotion at the time, which were largely based on the idea that emotions were the result of specific physiological states or external stimuli. Schachter and Singer argued that these theories were insufficient to explain the complexity and variability of human emotions, and proposed a new model that took into account both physiological and cognitive factors. The theory is based on the idea that emotions are the result of a two-factor process, in which physiological arousal is combined with cognitive labeling to produce a specific emotional experience.
Physiological Arousal
The first factor in the Schachter-Singer theory is physiological arousal, which refers to the physical sensations and changes that occur in the body in response to a stimulus. This can include changes in heart rate, blood pressure, and respiration, as well as other physical symptoms such as trembling or sweating. According to the theory, physiological arousal is a necessary but not sufficient condition for the experience of emotion. In other words, physiological arousal is required for an emotional experience to occur, but it is not enough on its own to determine the specific emotion that is experienced.
Cognitive Labeling
The second factor in the Schachter-Singer theory is cognitive labeling, which refers to the process of interpreting and making sense of the physiological arousal that is experienced. This involves the use of cognitive processes such as attention, perception, and memory to assign meaning to the physiological sensations that are experienced. According to the theory, cognitive labeling is the factor that determines the specific emotion that is experienced, as the same physiological arousal can be labeled in different ways depending on the context and the individual’s past experiences.
Emotion | Physiological Arousal | Cognitive Labeling |
---|---|---|
Fear | Increased heart rate, sweating | Interpretation of arousal as threatening or dangerous |
Anger | Increased blood pressure, tense muscles | Interpretation of arousal as frustrating or unjust |
Joy | Increased respiration, smiling | Interpretation of arousal as pleasurable or satisfying |

Key Points
- The Schachter-Singer theory is a two-factor theory of emotion that posits that emotions are the result of a combination of physiological arousal and cognitive labeling.
- Physiological arousal is a necessary but not sufficient condition for the experience of emotion, and cognitive labeling is the factor that determines the specific emotion that is experienced.
- The theory suggests that emotions are not simply the result of automatic or instinctual responses, but rather the result of a complex interaction between physiological and cognitive factors.
- The Schachter-Singer theory has been influential in the development of cognitive theories of emotion, and has been applied in a variety of fields, including psychology, neuroscience, and philosophy.
- The theory highlights the importance of cognitive processes in the experience of emotion, and suggests that emotions are not simply the result of internal physiological states or external environmental stimuli, but rather the result of an interaction between the two.
Criticisms and Limitations of the Schachter-Singer Theory

While the Schachter-Singer theory has been influential in the development of cognitive theories of emotion, it has also been subject to a number of criticisms and limitations. One of the main criticisms of the theory is that it oversimplifies the complex and multifaceted nature of human emotions, and fails to take into account the role of other factors, such as social and cultural influences, in the experience of emotion. Additionally, the theory has been criticized for its lack of empirical support, and for its failure to provide a clear and consistent definition of the terms “physiological arousal” and “cognitive labeling”.
Empirical Support
Despite the criticisms and limitations of the Schachter-Singer theory, it has been supported by a number of empirical studies. For example, studies have shown that individuals who are aroused physiologically and then given a cognitive label for their arousal are more likely to experience a specific emotion than individuals who are not given a cognitive label. Additionally, studies have shown that the same physiological arousal can be labeled in different ways depending on the context and the individual’s past experiences, which supports the idea that cognitive labeling plays a crucial role in the experience of emotion.
What is the Schachter-Singer theory of emotion?
+The Schachter-Singer theory is a two-factor theory of emotion that posits that emotions are the result of a combination of physiological arousal and cognitive labeling.
What is the role of physiological arousal in the experience of emotion?
+Physiological arousal is a necessary but not sufficient condition for the experience of emotion, and it provides the raw material for the experience of emotion.
What is the role of cognitive labeling in the experience of emotion?
+Cognitive labeling is the factor that determines the specific emotion that is experienced, as it involves the interpretation and meaning-making of the physiological arousal that is experienced.
In conclusion, the Schachter-Singer theory is a complex and multifaceted theory of emotion that highlights the importance of cognitive processes in the experience of emotion. While it has been subject to a number of criticisms and limitations, it has also been supported by a number of empirical studies, and continues to be an influential theory in the field of emotion research. By understanding the role of physiological arousal and cognitive labeling in the experience of emotion, we can gain a deeper insight into the complex and multifaceted nature of human emotions, and develop more effective strategies for managing and regulating our emotional experiences.
