AP PSYCHOLOGY

Detailed explanation-1: -Schachter and Singer found that participants uninformed about the injection’s true side effects felt either happier or angrier compared to informed participants. Since participants didn’t know the injection would affect their physiological arousal, they interpreted such reactions based on their confederate’s mood.

Detailed explanation-2: -The Schachter and Singer experiment, published in 1962, is one of the famous and controversial in the history of psychology. Some test subjects were secretly injected with adrenaline, giving them a sudden, unexplained surge of arousal. Subjects experienced this surge differently depending on context.

Detailed explanation-3: -According to the Schachter-Singer theory of emotion, developed in 1962, there are two key components of an emotion: physical arousal and a cognitive label. In other words, the experience of emotion involves first having some kind of physiological response which the mind then identifies.

Detailed explanation-4: -Schachter and Singer’s (1962) Two-Factor Theory of Emotion suggests that physiological arousal determines the strength of the emotion, while cognitive appraisal identifies the emotion label. So, in this theory, the “two-factor” represents physiological change and cognitive appraisal change.
