The statement that rules do not have the capacity to influence or alter motivating operations is incorrect Rules can indeed affect motivating operations MOs For instance a rule like If you dont save money now you wont be able to afford that new car later can increase the value of saving money establishing operation and evoke saving behavior Conversely a rule like Youll get paid next week regardless of how much you work this week might decrease the value of working hard abolishing operation Therefore rules can powerfully alter the effectiveness of consequences and influence the evocative effects of antecedents The other statements are true A Rulegoverned behavior is often called instructional control as rules provide a form of control over behavior B Effective rules clearly specify what consequences reinforcement or punishment will occur if a behavior is performed or not performed C By their very nature rules are verbal antecedents that must precede the behavior they are meant to govern in order to influence it
