Suppose you assign the least desirable tasks to a worker until he performs well and only then assign him the desired assignments he wants. This OB Mod strategy is known as __________.

A) positive reinforcement
B) extinction
C) punishment
D) negative reinforcement
E) parallel reinforcement

This OB Mod strategy is known as negative reinforcement, which involves the removal of an unpleasant stimulus (in this case, the least desirable tasks) in response to desired behavior (performing well). Once the worker performs well, they are rewarded with the desired assignments they want. Positive reinforcement involves the addition of a positive stimulus in response to desired behavior, extinction involves the removal of a positive stimulus in response to undesired behavior, and punishment involves the addition of an unpleasant stimulus in response to undesired behavior. Parallel reinforcement is not a recognized term in OB Mod strategies.
