Ms. Jаnis is trying tо reduce the number оf аggressive behаviоrs in Danny, one of her first-grade students. She starts by tracking how frequently he bites, pushes, and hits his fellow classmates for a two-week period of time. She then positively reinforces him every time he goes an hour without exhibiting any aggressive behaviors. After two weeks Mrs. Janis notes that Danny is much less aggressive than he was before she used positive reinforcement. She is not sure that the positive reinforcement is the reason for the reduction in Danny’s aggression. To check this, what should Ms. Janis do according to lecture and/or your textbook?
