Assume that Joe and Sarah, from the figure shown, are also dating, in addition to working together on the
joint school project. Further assume that Joe is madly in love with Sarah, who is an excellent student.
Sarah tells Joe that she will break up with him if he does not put forth high effort on this project. This
future punishment by Sarah is an example of:
