Schachter+and+Singer+-+Period+1

To test Schachter and Singer's two-factor theory of emotion
 * Aim:**

If a person is psychologically aroused and does not know the cause of this arousal, then he will try to find a reason for that feeling. He will label the feelings according to the cognitions available to him at the time.
 * Hypothesis:**

If a person experiences a state of arousal for which he has an explanation, then he has no need to label his feelings.

If a person is in a situation which should make him feel a certain way, but is not psychologically aroused, he will not have any emotion.
