Answer:
The group who has been informed has been least likely to experience emotions such as euphoric or angrier.
Step-by-step explanation:
Sactacher and Singer were hypothesized that if the person does not have any idea about emotions, they do not have any explanation about the emotions. They can label that experience only when they have experienced those emotions or feelings at that moment.
Thus here the people who have no idea about their emotional explanation were more susceptible to the emotional influence for the confederate.
