Ah-Aloud Method
This experimental technique allows us to observe the real-time emotions of the experimental participants. The magnitude and tone of the "Ah" that participants vocalize during the task are used to determine the ups and downs of their emotions and the type of emotion they are experiencing. Since "Ah" is used as an emotional verb in daily life, it is easy to determine the emotion, and since it does not require tools or equipment, it is useful for casual experiments.
