The James-Lange Theory of Emotion (AQA GCSE Psychology): Revision Note

Physical arousal leads to emotion

• The James-Lange theory of emotion is an explanation of how emotions are produced, based on the physiological arousal involved in the fight or flight response

• The theory suggests that emotions occur as the result of the physiological reaction experienced by someone who is in the presence of a threat/danger

• According to the James-Lange theory, receiving an external stimulus leads to a physiological reaction which will then determine the nature of the emotional response

• Therefore your emotional reaction depends on how you interpret your own, bodily, and physiological reactions, e.g:

  • You are walking home at night down a dark street and you hear footsteps behind you (adrenaline is released into your bloodstream)

  • You begin to breathe faster, you start to shake, your hairs stand on end, and your heart rate increases

  • The James-Lange theory proposes that you will interpret these physical sensations and conclude that ‘I am frightened’

• Emotions are feelings which come about as a result of physiological changes; they are not the cause of these changes

• This can be summarised as:

Event → Physiological Reaction → Interpretation of Physical Response → Emotion

• According to the James-Lange theory theory it is impossible to feel an emotion if there is no accompanying physiological reaction/sensations

Evaluation of the James-Lange theory of emotion

Strengths

• The theory is supported by real-life examples of emotions following physiological arousal, such as phobias or panic disorders: a trip or fall in public can lead to an emotional reaction such as anxiety or embarrassment

  • This can lead to the avoidance of similar public situations as an association is formed between the situation and the emotion

• The theory may explain extreme emotional responses e.g. to phobic stimuli as the physical reaction may precede the emotional reaction

Weaknesses

• The theory is possibly too simple:

  • The physical reactions to a fear stimulus may be the same as those elicited by being in love or riding on a roller coaster, thus it lacks validity

• Schachter and Singer's (1962) two-factor theory agrees that physiological arousal comes before emotion, as the James-Lange theory suggests, but argues that social cues are also needed to correctly label the emotion

  • E.g. the same racing heart could be interpreted as fear (hearing footsteps in a dark alley) or excitement (kissing someone you like), depending on the situation

• Cannon-Bard challenged the theory in the 1920s, saying that emotions occur at the same time as the physiological response

  • Furthermore, the physiological response to exercising vigorously is not interpreted as a fear response even though it shares features of the same e.g. raised heart rate, sweating etc
