James-Lange Theory of Emotion

Core Concept

• Physical changes in the body precede the experience of emotion, according to the James-Lange theory of emotion.
• Emotions arise from the interpretation of physical sensations.
• For instance, a racing heart leads to the realization of fear.

Origin and Definition

• It is one of the earliest attempts to explain emotions, independently proposed by William James and Carl Lange.
• Emotions occur as a result of physiological reactions to events.
• People have a physiological response to stimuli, triggering an emotional experience.

Theory in Action

• An external stimulus leads to a physiological response and the emotional reaction depends on how those physical reactions are interpreted.
• Example: Seeing a bear causes trembling and a racing heart; these physical reactions are interpreted as fear.
• Bodily changes directly follow the perception of an exciting fact, with the feeling of those changes being the emotion itself.
• Example: Seeing a dark figure in a parking garage causes a racing heart, interpreted as fear which prompts the action of running away.
• Imagining an emotion would be a flat version of the real feeling.
• A physical reaction is required to experience real emotion.

Impact and Prominent Dissenters

• It shifted the understanding of emotional response, suggesting physiological responses precede cognitive perception.
• The theory suggests that physiological responses occur first and play a major role in the experience of emotion.
• Wilhelm Wundt was an early critic, suggesting emotions are primal, hard-wired sensory responses.
• The Cannon-Bard theory, proposed in the 1920s by Walter Cannon and Philip Bard, states that emotions cause physiological reactions.

Modern Views and Criticisms

• Modern researchers largely discount the theory, but there are instances where physiological responses lead to emotions.
• Panic disorder and phobias are examples where physical reactions lead to emotional experiences.
• Forming an association between a situation and emotional state might cause an aversion to things that could trigger that particular emotion.
• Neither James nor Lange based their ideas upon controlled experiments, but on introspection and correlational research.
• Neuroscientists demonstrated flaws, finding that those with major sensory losses are still capable of experiencing emotions.
• Physiological responses are not always necessary to experience emotion.
• People with muscle paralysis can still feel happiness, fear and anger.
• Applying electrical stimulation produces different emotions each time.
• A person may have the same physiological response to a stimulus, yet experience an entirely different emotion.
• An individual's mental state, environmental cues, and others' reactions impact the emotional response.

Support and Relevance

• It maintains relevance today, as research continues to support parts of the original ideas.
• Advancements in technology provided a better understanding of the brain and body's reactions during emotional responses.
• A 1990 study found that making facial expressions for different emotions displayed slight differences in heart rate and skin temperature.
• Brain scan studies revealed that basic emotions elicit distinct patterns of activity in the brain.
• The perception of internal physical states play a role in experiencing emotions.
• People more sensitive to their body's physical signals experienced more negative emotions such as anxiety.

Concluding Thoughts

• It is one of the earliest theories that represents significant time and effort spent toward understanding emotional responses.
• The theory has been criticized and altered over the years, and is still influential today.
• Other theories include the Cannon-Bard theory and Schacter's two-factor theory.
• Emotional experiences are modified by both physiological reactions along with other information.
