Read the following example and select whether it is positive reinforcement, negative reinforcement, positive punishment, or negative punishment for Sallie

Ellie is a twenty three year old who got mad and started yelling her friend Sallie out when her friend did not want to go to the mall with her because she had to study. Her friend cried and went and said if it is that important to you, I will study later but please stop being mad and yelling at me. In the future Ellie is more likely to cuss at Sallie and Sallie is more likely to give in to get Ellie to stop being mad and yelling.
