Learning new behaviors is difficult and threatening. To ensure that trainees continue to demonstrate the skills they have learned, behavior must be reinforced. Reinforcement is a consequence that follows behavior. it can be positive (e.g., praise and financial rewards) or negative (e.g., ‘If you per- form as desired, I will quit screaming at you”), but the consequence must be contingent on performance. Often supervisors and coworkers can he might to reinforce desired changes. If a supervisor or coworker responds positively to a positive change in behavior, the frequency with which the new behavior win be displayed is likely to increase.
