Two-Factor Theory of Emotion

Also called Schachter–Singer theory

Emotion needs both undifferentiated arousal and a cognitive label, so the same bodily state reads as different emotions depending on context.

Schachter and Singer's 1962 adrenaline study: subjects given the same injection reported euphoria or anger depending on how a confederate behaved. Shares its name with Herzberg's two-factor theory of motivation, which is unrelated.

In practice

  • A candidate whose heart is racing before an interview reads it as dread in one building and as anticipation in another.
  • Two passengers in the same turbulence, one told it is routine and one told nothing, report irritation and fear from an identical set of sensations.
