Schachter-Singer Experiment

1962 epinephrine study supporting two-factor theory: arousal plus context yields the specific felt emotion.

Specifications & Metrics

Participants given epinephrine without explanation reported emotion matching a planted euphoric or angry accomplice.
Informed participants attributed their arousal to the injection and were less swayed by the context.
The design grounded the two-factor theory that emotion is arousal interpreted by cognitive label.
